It is visible to the naked eye. Still warm from its violent birth, a young Jupiter would glow in infrared light, like a distant heat lamp. Stephane Some astronomers thought the planet, called 51 Peg b for its parent star in the constellation Pegasus, was too bizarre to be real. et al, 2004). Earth hunters like Beichman compare the challenge to that of seeing a firefly hovering next to a lighthouse searchlight 3,000 miles (4,828 kilometers) away—with a little fog rolling in. of Mu Arae planned groups of observatories to search for a rocky inner planet in the "They're common enough that it looks like planet formation is a normal process." to Saturn and Titan Adaptive optics measures the scrambling with a special sensor, then sends the information to a flexible mirror that deforms and undulates many times a second—a frenetic funhouse mirror—to tidy up the image of the star. That leaves plenty of room to find alien Jupiters as searches become more sensitive. around 1.5 AU would disrupt the orbit of an Earth-type planet the TPF will include two complementary observatory groups: As of August 29, 2006, astronomers have announced the discovery Even then more than 99 of every 100 Earths would elude Kepler, because it will be able to detect only the half a percent that have orbits aligned so they pass directly in front of their stars. "d" (also called "c" by those unaware of now confirmed "c" (See an animation of the relative chromospheric inactivity suggest that the star is Frame by frame a Jupiter's influence churns an orderly set of embryos into an unruly, colliding swarm. 2006 BEAUGE C., FERRAZ-MELLO S. & MICHTCHENKO T.

The mu Arae planet found by the Europeans is bounded well to the outside by a Jupiter-mass planet. the Milky Way. in the Solar System), the planet It has a By 2011 or so he expects Kepler to have detected a few dozen Earth- or Mars-size planets set just far enough from their stars to be comfortable for life. Astronomers hoping to capture the light of an Earth-size planet around a star billions of times brighter compare the feat to picking a firefly from a searchlight's glare 3,000 miles (4,800 kilometers) away, on a foggy night. (McCarthy class codes, go to ChView's webpage on Further observations revealed the presence of a second object in the sys… A handful of Earth- and Mars-size planets take shape in the turmoil. Alan J. Penny, Kevin Apps, But it turned out to be the first of an avalanche. But Mu Arae's planet, and two others reported at about the same time by U.S. groups, are far smaller than their predecessors and could be made largely of rock. (shown here with Europa). Founded in 2433 by Earth-backed European colonial corporations, Mu Arae would become the UNSC's largest supplier of Iridium and Osmium, rare-Earth elements necessary in the construction of Shaw-Fujikawa Translight Engines, and a launch site for UNSC Navy, Marine and Army counter-insurg… Earth's night sky are now available from the Instead, from a vantage far beyond the moon, it will chase their shadows. The only planets able to yank their star fast enough to register on the instruments of the day would be the mass of Jupiter or more—hundreds of times heavier than Earth. ε Arae (Epsilon Arae) Epsilon Arae is a binary star system. "They probably have several very beautiful true Jupiter analogues in their data, and they're just waiting to get more data so they're really sure," says Laughlin. et al, 2004; and developmental scenario of inner migration from around 3 AUs under DSS Image via Wikisky Your system is mu Arae. Instead, even the best earthbound telescopes ordinarily see a star as a fat smudge. in an elliptical orbit (e= 0.31, revised from 0.20 +/- 0.03) "It's all just about deleting that star," he says. Its discovery was announced on June 13, 2002. These discoveries told of planetary turmoil—giants swept from remote birthplaces into hot, close orbits, and planetary siblings playing gravitational tug-of-war until one was flung into deep space. It has a maximum press release -- details below). "If SIM can detect a planet," says JPL's Michael Shao, the project scientist, "it can tell TPF when and where to look" for the light of an Earth. Larger image. Mu Arae c, also known as HD 160691 c, formally named Dulcinea (pronounced / dʌlˈsɪniə / or / dʌlsɪˈniːə /), is an extrasolar planet orbiting the star Mu Arae of the constellation Ara. top 100 target Ara. None of this star subtraction would be possible without adaptive optics—a means of sharpening telescope images. For now his team is betting on a pair of technologies. Each dark line indicates a wavelength of light soaked up by gases at the star's surface. Exoplanet News Click for more Hubble Pins Down Weird Exoplanet with Far-Flung Orbit Click for more About Half of Sun-Like Stars Could Host Rocky, Potentially Habitable Planets By now, astronomers tracking the wobbles of nearby stars have detected more than 130 alien planets. Some astronomers aren't waiting until planets as small as Earth are in reach. Robotically controlled for efficiency, the 2.4-meter (7.9-foot) Automated Planet Finder will capture every glimmer of starlight with mirrors plated with silver instead of the usual aluminum. the Astronomiches Rechen-Institut at Heidelberg's Hugh R. A. Jones, Larger If it stands up to the scrutiny of other scientists, this planet, around a star called Mu Arae, will be a milestone in the quest for another Earth. This system also has a superjovian planet in an extreme orbit, which astrophysicists think is beneficial to inner planets. It is visible to the naked eye. The star is named after Miguel de Cervantes, an important Spanish writer, and the planets are named after characters in the novel Don Quixote. The star has a radius estimated to be 31.5% greater than our Sun and is 75% more luminous. Jupiter relatively circular orbit (e= 0.0666 � 0.0122) which takes Terrestrial If it told of a watery, temperate place, humanity would face a 21st-century version of Copernicus's realization nearly 500 years ago that the Earth is not the center of the solar system. Mu Arae may be centered around 1.3 AU -- between the orbital In August 2006, two teams of In the disk of gas and dust that surrounds a newborn sun, giant planets are thought to form first, in a million years or so. They don't smash into each other, so they don't grow. et al, 2006). The following table includes all star systems known to be Called extreme adaptive optics, it would replace the hundreds of tiny pistons that reshape current flexible mirrors with thousands of smaller ones, and correct the light not hundreds but thousands of times a second. NASA "That's a hard, challenging technology problem," says Charles Beichman, the project scientist for the Terrestrial Planet Finder (TPF) mission. More giants quickly turned up, some in searingly close orbits—"roasters," as some astronomers now call them—and others careering near and far with each orbit, on wildly eccentric, or oblong, paths. The planet around Mu Arae weighs at least 14 times as much as Earth—"an Earth on steroids," says one astronomer. It is scorchingly close to its star, completing an orbit every 9.5 days. Nearby It harbors two other planets. orbital period around 1.31 years (478 days). Woolf and others have found they can unscramble Earthshine to see the imprint of gases in our atmosphere, the color of the oceans, and the blue of the sky. Queloz, planetary and potentially astronomers announced the discovery of a third planet with and Nuno et al, forthcoming, in It was the first ' hot Neptune ' or ' mega-Earth ' to be discovered. habitable zone orbits of this system, with a table of To be visible to an earthbound telescope, an alien Jupiter would have to be several times bigger or much younger—say half a billion years old instead of nearly five. giant planet in an outer orbit was also suspected (Jones et Planetary candidates "b" and "c" appear Anglo-Australian Planet Search data; RV curve and planet data (California and Carnegie Planet Search) Starting in 2006, its dual mirrors will peer into space side-by-side like the saucer eyes of an owl, looking for Jupiters. For more information about stars including spectral and luminosity With its powerful gravity, "Jjupiter is going to gradually pull on them and make their orbits more eccentric." Inside, darkened corridors lead to a door that Michel Mayor opens with a magnetic card. The four-planet system of mu Arae is not a record-breaker; the current leader, up to 2009, is 55 Cancri A which boasts five planets. Their strategy was to break the light of each star into all its colors, producing a spectrum, banded with dark lines like a bar code. If the atmosphere is rich in oxygen or its chemical cousin, ozone, TPF should detect it. The next day the team leader, veteran planet hunter Michel Mayor of the University of Geneva, decides that it's time to announce the discovery. separation of 0.43 arc-seconds (about 6.6 AUs) from Mu Arae, The telltale shift in the lines can be minuscule—no more than the width of a dozen or so atoms on a detector, for planets as small as his group's latest prize. That feat, called nulling interferometry, relies on the fact that light waves have crests and troughs, just like waves on water. Planetary candidate "d" may be rocky image candidate "e" with at least half (52.19 percent) of Jupiter's mass In August 2006, two teams of "I like it," the Swiss astronomer says, beaming. Chris The dip due to an Earth would be so tiny—less than one part in 10,000—that it could be seen only from space. Astronomers are hoping to use NASA's Silvery optical fibers snake into the innermost room, carrying starlight from the 3.6-meter (11.8-foot) telescope above. Outside is the daytime brilliance of northern Chile's mountainous desert. beginning in 2015. Weeks before the Swiss team was sure of the Mu Arae discovery, two U.S. groups had quietly firmed up the case for other small worlds. But if that far-off world has an atmosphere like ours, TPF should be able to see signs such as carbon dioxide and water vapor. like our Sun, Sol. From the ground this optical wizardry could see a Jupiter-size planet. eccentric orbit of planet b at an average orbital distance of Mu Arae c, also known as HD 160691 c, is an extrasolar planet orbiting around Mu Arae. But it would be harder to spot such a planet in the glare of a normal star. Mu Arae is a yellow-orange star A rhythmic wavelength shift in a star's spectrum, back and forth, can mean that the star is heading toward us, then away. more highly evolved and probably older than Sol, at around in an inner orbit Very close in orbit is planet Mu Arae d which is about 14 times the mass of the Earth and therefore one of the lightest planets discovered and probably a massive rocky planet. Macintosh and others are working on a new version of adaptive optics that could deliver smoking guns by the dozen. The planet has a mass about half that of Jupiter and orbits at a distance of 0.921 AU from the star with a period of 310.55 days. So astronomers are eager to find more. distances of Earth and Mars in the Solar System -- with an JPL, That's because stars pulse and roil, creating surface motions that would make it impossible to detect a star's tiny drift—barely a crawl—under the spell of an Earth. At the moment, no one on the mountain does. "We can dream," says Queloz. Gozdiewski et al, To be launched in 2007, it won't capture light from other Earths. distances of Earth and Mars in the Solar System -- with an Gaspare Lo Curto, from the Behind it is another door, massively padlocked. Mu Arae e is a gas giant at least 1.8 times as massive as Jupiter. The extent of the shift is a rough gauge of the object's mass, and the timing tells how long it takes to complete an orbit. Planetary Migration and Extrasolar Planets in the 2/1 Mean-Motion Resonance. Steven S. Vogt, pdf, The planet orbits a star called mu Arae every 9.5 days, which is located 50 light-years away in the southern constellation of the Altar. data, planet "b" has at least 1.67 +/- 0.11 times Jupiter's mass. Sylvie Mu Arae has 4 planets: Mu Arae B, discovered in 2000, has a mass 532.7 times the mass of Earth and an orbital period of 643.25 days. 1. mu Arae, stellar object 1.1. mu Arae b, planet, semi-major axis: 1.500AU 1.2. mu Arae c, planet, semi-major axis: 0.0909AU 1.3. mu Arae d, planet, semi-major axis: 0.921AU 1.4. mu Arae e, planet, semi-major axis: 5.24AU Extrasolar A few roaster planets have even been glimpsed more directly when they transit their star, crossing its face and dimming its light like a beetle crawling across a lamp. The orbit of an Earth-like planet (with liquid water) around to be gas giants It just might allow HARPS to detect similar planets—say 20 times Earth's mass, or roughly the mass of Neptune—in orbits the size of Earth's. "I like it a lot. As astrobiologist Vikki Meadows of JPL explains, "That would give us a good clue that something funny is going on, because we don't think we can create large amounts of oxygen without life. Uranus and Based on the abundance of iron, it is around twice as enriched in heavy elements as our Sun, and is therefore described as metal-rich. Stars Database.). Its discovery was announced on August 25, 2004. Paul Butler and his colleagues added their own bantamweight, at 21 Earths. The next step is actually taking a picture of an alien planet. However, the The result is a protected zone where Earth survives. None of this would be happening if not for the winter nights that Didier Queloz, then a Ph.D. student at the University of Geneva, spent a decade ago at a telescope high on a plateau in southern France. There the Large Binocular Telescope (LBT) is taking form. Earlier in the evening, between cups of espresso and cigarette breaks, Naef gloomily eyed a display of weather data. (See an animation of the. Roger Wilcox's Internet mid-infrared telescopes and a fourth communications hub astronomers confirmed that they had discovered a fourth planet All in all, says Laughlin, "it's a bonanza if you can find a planet transiting a bright star." Roasters and eccentric giants are nothing like the planets we know, and the gravitational tug of these rampaging giants could threaten the survival of Earthlike planets. Dominique Naef, At labs and mountaintop domes, engineers are at work on technologies capable of recording a planet's meager glow next to the glare of its sun. Called Earthshine, it's sunlight reflected from Earth onto the moon's rough surface and then back again. Planet Finder (TPF), ; Mu Arae C, discovered in 2004, has a mass 10.6 times the mass of Earth and an orbital period of 9.64 days. Cassini-Huygens Mission Cassini-Huygens Mission and an illustration, go to Christine Kronberg's He has fitted a telescope on Maui with a set of precisely sized masks that physically block the starlight. Like the oscillations that planet hunters watch from the ground, this subtle shimmy would imply an unseen dance partner—a planet that might be only a little bigger than our own. The planet Butler and his colleagues, including Geoff Marcy of the University of California, Berkeley, and Debra Fischer, may be just a few measurements away from announcing the real thing. Forty years ago William Borucki helped design heat shields for the Apollo moon missions. (See an animation of the NASA Sheer size will allow the LBT to see fainter objects than all but a handful of other telescopes in the world. In a workshop under the bleachers of the University of Arizona's football stadium in Tucson, a telescope mirror the size of a small skating rink rests in a cradle. Willy Benz, The shine from another Earth could be millions of times fainter, and would be far less informative, at least to a first generation planet finder. As Mu Arae with at least half of Jupiter's mass (more below -- They captured one more reading of the star's motion before, minutes later, the humidity shot up again and the operator called a halt for the night. Macintosh says that after examining a hundred stars, "we have candidates"—faint spots that might be a planet but could also be a star in the background—"but nothing I would describe as an obvious smoking gun.". Dust clumps together into gravel, gravel to rocks, and rocks to hundreds of planetary embryos about the size of Earth's moon. The leftovers provide the raw material for smaller planets. Mu Arae b 643.25 1.497 Mu Arae c 9.6386 0.09094 Mu Arae d 310.55 0.921 Mu Arae e 4205.8 5.235 Mu Arae f* 2301.4 3.478 *Unconfirmed planet you are trying to verify You are working on a team that is trying to analyze this data. Larger Then the humidity dropped, and the telescope operator gave the go-ahead. et al, 2004). Planet Finder (TPF) and the ESA's team. Even then the LBT probably couldn't see an exact counterpart of our Jupiter, dimly lighted by its distant sun. TPF-C Planet press release). It is scorchingly close to its star, completing an orbit every 9.5 days. complete. With the right filters, he hopes to dim the star and make any planet pop out. candidate) in a very hot but circular, inner orbit (e~0) +/- 0.02 AUs (a semi-major axis around Mars's orbital distance) of a second giant planet of around 3.10 +/- 0.71 Jupiter-masses Pepe (Johnson Mu Arae is the second extrasolar system known to host four planets. "That would get us a bunch of real planets," Macintosh says—hot young Jupiters at a Jupiter's distance. based on a residual trend in radial velocity measurements over Ares IV (also known as Mu Arae d or Tolatuih) was a Unified Earth colony in the Mu Arae System approximately 50.592 lightyears from Sol. around 1.5 AU would disrupt the orbit of an Earth-type planet is likely to have an "essentially rocky core" with an atmosphere of On August 25, 2004, a team of astronomers The key is to blot out the lighthouse while leaving a clear view of the firefly. somewhat larger than Observability Predictor Remarks 29 Aug. 04: The denomination of planets c and d is provisional; there is indeed a planet candidate c (P = 1300 d) proposed by Jones et al (2002) before the 9.55 d. period planet announced by the Geneva group Other web-pages. In fact, the way is barred because it would be all too easy to perturb the exquisite temperature control, high vacuum, and optical stability that allow HARPS to sift starlight for hints of planets smaller than any yet detected. First to fly, in 2014, would be a single telescope, with a mirror perhaps 21 feet (6.4 meters) across and clever masks to banish starlight from the spot where a planet might appear. or gaseous like (ESO "formation-flying" infrared interferometer to launch before et al, 2004; and Louis de La Caille (1713-1762), who had the great honor of naming Vauclair, Michael Bazot, CP(D)-51 10535, SAO 244981, FK5 662, and LTT 7053. of four planetary candidates around Mu Arae. orbital distance of about 0.921 AUs, close to Earth's orbital A group at the Very Large Telescope in Chile has already glimpsed what may be a newborn giant planet near a dim brown dwarf. It's the same strategy that has yielded nearly all the planets found to date. A planet as small as our own, however, will remain out of reach for both teams. It is the second planet discovered around this star and completes a full revolution in 9.5 days. (including Nuno C. Although lighter than Jupiter, this one is bloated to a diameter 35 percent greater. 6.41 billion years Planet Finder (TPF), It lies in the northeastern By precisely aligning the light waves gathered by the two mirrors from a particular point in the sky, astronomers can overlap the wave crests from one mirror with the troughs from the other so that the light simply cancels out. et al, 2006). I want to find that.". Udry, Christophe Lovis, its core is moving the star out of the main sequence into The new exoplanet orbits the bright star mu Arae located in the southern constellation of the Altar. In July 2014 the International Astronomical Union launched a process for giving proper names to certain exoplanets and their host stars. Subtle color changes as starlight shines through the planet's heat-swollen atmosphere are also yielding hints about what this alien world is made of—hydrogen, helium, and sodium, for starters—as well as signs that it is slowly evaporating in the heat. It's just another glimpse, but it's enough to turn a suspicion into a near certainty. Arae as a prime target for the Because that's what I want. "Picture an astronaut on the moon holding a nickel edge on," says Stephen Edberg, a SIM scientist at the Jet Propulsion Laboratory (JPL) in Pasadena. to complete (McCarthy a visible-light coronagraph to launch around 2014; and a exoplanets.org). Seeing alien Jupiters is proving hard enough, and a planet as small as Earth would be far more elusive, snuggled right next to a star shining ten million to ten billion times brighter, with an unknown amount of interplanetary dust adding its own distracting glow. habitable zone orbits of this system, with a table of The recent discoveries bring the total number of known extrasolar planets around normal, sun-like stars to 193. It gives a quick overview of the hierarchical architecture. But they were also trying their luck in a game that had disappointed many other astronomers before them: hunting for alien planets. Additional information may be available at press release). The star may be 1.8 to 1.9 times as or ps). In space, aboard a multibillion-dollar mission called the Terrestrial Planet Finder that's scheduled to fly in a decade or so, it could pick up the light of a planet no bigger than Earth. "You'd like not to have zero [Earths]," says Beichman, adding wryly, "Zero is a bad number, because you get called up in front of Congress and asked how come you spent a billion dollars and didn't find anything.". (Pepe et al, 2006). The new planet orbits about 13 million kilometres from mu Arae, with a year lasting only 9.5 Earth days, and it has about 14 times the mass of Earth. Nearby Mu Arae is a yellow star 50 light years from Earth, it is known to have a system of 4 planets, three of them comparable to Jupiter, it is somewhat larger than the Sun, it is a little more massive, and it … By the time TPF is launched, astronomers should also have an idea which stars are the best prospects. All rights reserved. al, 2002, in 2020 National Geographic Partners, LLC. Among other characteristics, astronomers can measure the surface temperatures, orbits, magnetic fields, and colors of exoplanets. CalTech, of this star and its position relative to the Milky Way, On December 11, 2000, a team of astronomers (including, The orbit of an Earth-like planet (with liquid water) around The planet around Mu Arae weighs at least 14 times as much as Earth—"an Earth on steroids," says one astronomer. Planetary candidates "e" appears to In 2001, an extrasolar planet was announced by the Anglo-Australian Planet Search team, together with the planet orbiting Epsilon Reticuli. The Stars of IX. (AAO around the mass of Uranus the influence of outer giant planet "b" now at 1.5 AUs, this planet (McCarthy It moves around Mu Arae at an average distance of only 1.50 +/- 0.02 AUs (a semi-major axis around Mars's orbital distance) in an elliptical orbit (e= 0.31, revised from 0.20 +/- 0.03) that takes around 1.79 years (654.5, revised from 645.5 +/- 3 days) But there are other ways to parse starlight for hints of real Earths. so-called "Maybe it was intuition, maybe it was luck," he says. Its host star is located in the constellation of The Altar. But astronomers are convinced they will soon be finding solar systems where small, temperate planets like Earth could form and where some kind of life might flourish. But HARPS, up and running since late 2003, brings many times more precision to the task than Mayor's earlier instruments—precision enough to tell when a star tens of light-years away is moving toward or away from Earth at a speed no greater than a walk. "That's why I work so hard every day. Mu Arae d. Mu Arae d, also known as HD 160691 d, later named Rocinante, is an extrasolar planet orbiting the star Mu Arae of the constellation Ara.
