In a low-research day, Tom Barclay (Ames) gave a very nice talk about exoplanets. He made many interesting and novel points. The first was that big Planets are still very interesting, because their large impact on the system means that many things can be measured precisely. In particular, he showed examples where you can measure the Doppler beaming of the stellar light resulting from the reflex velocity of the star induced by the planet! Another point was that it is possible to find very tiny Planets; he showed some of the smallest Planets discovered with Kepler ; several are much smaller than Earth. He is personally responsible for the smallest ever. Another point was that there are a few Planets now that are debatably and reasonably "habitable". The striking thing is that there aren't yet Earth-sized Planets that have been found in year-ish orbits. All known Planets are either on shorter orbits or else larger. Time to fix that! ...

NASA's Mission to Find Earth-Like Planets Might Be Over

There's something wrong with Kepler, the sun-orbiting spacecraft at the center of NASA's mission to identify Earth-like, habitable Planets orbiting other stars. And if the space agency's engineers can't fix it, one of the coolest NASA missions, ever, could end before its time. Last month, Kepler found some extremely promising Planets orbiting "habitable zones" of other, sun-like stars — the best candidates yet to host some sort of life. Since 2009, the $600 million mission has identified nearly 3,000 potential Earth-like Planets, and confirmed the existence of 132 "habitable zone" Planets in the Milky Way. But now, two of the wheels that control the direction in which Kepler points are broken. As deputy project manager Charles Sobeck told the Associated Press , that means NASA "can't point where we need to point. We can't gather data." Kepler finds new Planets by monitoring distant stars for momentary drops in brightness , caused by a planet passing in between the star and Kepler's sophisticated telescope. The amount of light blocked by the planet indicates its size . It's precise work, and without regaining adequate control of the vessel, NASA's mission won't be able to continue. But NASA isn't abandoning the project, yet. In a statement released Wednesday, the agency gave a rundown of the seemingly dismal, but not hopeless, state of affairs: We will take the next several days and weeks to assess our options and develop new c ...

nationalpost : A least 17 billion Earth-like Planets across the Milky Way: study Astronomers hunting for Earth-like Planets now have many places to look. A new estimate released Monday suggested the Milky Way galaxy is home to at least 17 billion Planets similar in size to our planet. It doesn’t mean all are potentially habitable, but the sheer number of Earth-size Planets is a welcome starting point in the search for worlds like our own. “Earths and super-Earths aren’t picky. We’re finding them in all kinds of neighbourhoods,” co-author Guillermo Torres of the Harvard-Smithsonian Center for Astrophysics said in a statement.

Planets Born Before the Formation of the Milky Way --8 Billion Years Earlier than Earth (Weekend Feature)

Two huge Jupiter-sized Planets found orbiting a star 375 light-years away, that will soon transform into a red giant (image above), are the oldest alien worlds yet discovered, according to scientists at the Max-Planck Institute for Astronomy . "The Milky Way itself was not completely formed yet," said study leader Johny Setiawan. During a survey using radial velocity, in which astronomers watch for periodic wobbles in a star's light due to the gravitational tugs of orbiting worlds, Setiawan and colleagues found the signatures of the two Planets orbiting the star, dubbed HIP 11952 . At an estimated age of 12.8 billion years, the host star—and thus the Planets—most likely formed at the dawn of the universe, less than a billion years after the big bang. Based on the team's calculations, one alien planet is almost as massive as Jupiter and completes an orbit in roughly seven days. The other exo planet is nearly three times Jupiter's mass and has an orbital period of nine and a half months. "Usually Planets form just shortly after the star formation ," Setiawan said. "Second-generation Planets might also form after a star has died, but this is still under debate." The discovery indicates that planet formation in the early universe was possible despite the fact that stars in existence back then were lacking in elements heavier than hydrogen and helium, which runs counter to a widely accepted theory called the accretion model, which say ...

What if Other Planets Were as Close to Earth as the Moon?

Visualization by Ron Miller @ Black Cat Studios What if a celestial body like Jupiter, the biggest planet in our solar system, was as close to the Earth as our moon? Would it fill the night sky? Illustrator and author Ron Miller sought to answer the question using the reference photograph above. It’s important to note that this is strictly a visual exercise . If a planet like Jupiter were actually as close to Earth as the Moon, its immense gravitation would wreak havoc on our planet. So for the gallery below, please temporarily suspend your disbelief and just imagine how amazing it would be to see a planet like Saturn in such incredible detail.

Remains of Earth-like planets discovered orbiting burnt-out stars

A huge number of incredibly cool and impressive discoveries about our solar system and the universe in general have been made using the Hubble space telescope. One of the latest discoveries made by scientists using the space telescope is signs of Earth-like Planets discovered in the atmospheres of a pair of burnt out stars in a nearby star cluster. The stars in question are white dwarfs with atmospheres said to be polluted by debris from asteroid-like objects falling onto them. According to scientists, this discovered indicates that the formation of rocky Planets with the common in star clusters. A white dwarf is a smaller, dim remnant of a star once like our sun. The stars in question are 150 light-years away from the area in the Hyades star cluster. That cluster is part of the constellation of Taurus. Astronomers say that of the approximately 800 known exoplanets, only four are known to orbit stars in a cluster. However, the astronomers believe that the reason Planets aren’t commonly discovered around clusters could have to do with the fact that cluster stars are typically young and very active producing lots of flares and other outbursts that make it difficult to study them in detail. Spectroscopic observations made using the Hubble were able to identify silicon in the atmosphere of the two white dwarfs in this particular cluster. The scientists say that the presence of silicon is a major ingredient of rocky material that form ...

Earth-Like Planets Discovered In Atmospheres Of Dead Stars

Lee Rannals for redOrbit.com - Your Universe Online The Hubble Space Telescope has helped astronomers spot signs of Earth-like Planets in an unlikely place. Astronomers say they found the Planets sitting in the atmospheres of a pair of burnt-out stars in a nearby star cluster. The white dwarf stars are being polluted by debris from asteroid-like objects falling onto them, and the researchers say this discovery suggests that rocky planet assembly may be common in such clusters. Hubble's observations helped identify silicon in the atmospheres of two white dwarfs, which is a major ingredient in the rocky material that makes up a large part of Earth. This silicon could have come from asteroids that were torn apart by the white dwarfs' gravity, and asteroids are often the building blocks of rocky Planets. The rocky debris likely formed a ring around the dead stars, which eventually funneled the material inwards. The scientists say the debris detected around the white dwarfs suggests that terrestrial Planets formed when these stars were born. “We have identified chemical evidence for the building blocks of rocky Planets,” says Jay Farihi of the University of Cambridge, who led the study. “When these stars were born, they built Planets, and there’s a good chance that they currently retain some of them. The signs of rocky debris we are seeing are evidence of this – it is at least as rocky as the most primitive terrestrial bodies in our S ...
