#but some of these planets seem to be distinctly rocky and Earthlike: Kepler-62e, Gliese-581g and Kepler 22b, to name but a few."
and ultimately life on such planets, is one of the great frontiers of science, perhaps the last big piece in the puzzle of how we, humans,
Two of the more high-profile planet hunters have hit rocky ground in recent months, however.
Thankfully, more planet-hunting missions are on the way, which will continue and even extend upon their legacy.
a planet has to be similar to Earth in size, rocky, and located in the so-called Goldilocks zone#an area of space around a parent star that is not too cold or too hot,
Since these planets are expected to be small and faint compared to their sun, spotting them is tricky with existing ground-based optical telescopes."
Hence it takes an extremely large telescope to try to spot any planets that may support alien life many light years away.
But even with these adaptive optics tools, existing ground-based telescopes can only"see#planets bigger than Jupiter#gas giants that orbit their parent stars at a huge distance.

unable to support life. Using an instrument called a coronagraph, JWST will try to determine
whether a planet has an atmosphere, and#for the first time#analyse it by examining the spectrum of the light coming from the planet.
Elements and molecules in an atmosphere, such as water and oxygen, have specific signatures in the spectrum,
most exoplanets are still found using indirect techniques#such as detecting a wobble in the position of the star that indicates it is being pulled slightly towards an orbiting planet,
which planets are identified by the tiny dip in brightness caused when they pass in front of its star.
but the method doesn't allow us to calculate a planet's mass#a critical factor in determining its density and hence its rockiness.
It studies space bodies by recording how a planet's gravity makes its parent star appear to vibrate as it rotates around it.
It can use that vibration to detect new planets, but has also been used to learn more about known exoplanets.
if it wasn't for its proximity to its parent star#the planet lies only 2. 5 million km (1. 6 million miles) away from it,
which gives you both the mass and radius of the planet, so you can start to say what it's made of,

The discovery reported in the journal Science lends weight to the idea that biologically crucial molecules like amino acids that are commonly found in meteorites are produced early in the process of star formation even before planets such as Earth are formed.

The scrutinized planet which is known as GJ1214B is classified as a super-Earth type planet because its mass is intermediate between those of Earth and Neptune.
Recent searches for planets around other stars (xoplanets have shown that super-Earths like GJ 1214b are among the most common type of planets in the Milky way galaxy.
Because no such planets exist in our solar system the physical nature of super-Earths is largely unknown.
Previous studies of GJ 1214b yielded two possible interpretations of the planet s atmosphere. Its atmosphere could consist entirely of water vapor
or some other type of heavy molecule or it could contain high-altitude clouds that prevent the observation of what lies underneath.
NASA ESA and G. Bacon (STSCL) via U. Chicago) The researchers describe their work as an important milestone on the road to identifying potentially habitable Earthlike planets beyond our Solar system.
and really nail down some property of a small planet orbiting a distant starexplains Bean an assistant professor and the project s principal investigator.
Kreidberg Bean and their colleagues used Hubble to precisely measure the spectrum of GJ 1214b in near-infrared light finding what they consider definitive evidence of high clouds blanketing the planet.
The planet was discovered in 2009 by the MEARTH Project which monitors two thousand red dwarf stars for transiting planets.
The planet was targeted next for follow-up observations to characterize its atmosphere. The first spectra which Bean obtained in 2010 using a ground-based telescope suggested that the planet s atmosphere either was predominantly water vapor
or hydrogen-dominated with high-altitude clouds. More precise Hubble observations made in 2012 and 2013 allowed the team to distinguish between these two scenarios.
The news is about what they didn t find. The Hubble spectra revealed no chemical fingerprints whatsoever in the planet s atmosphere.
This allowed the astronomers to rule out cloud-free atmospheres made of water vapor methane nitrogen carbon monoxide or carbon dioxide.
The best explanation for the new data is that there are high-altitude clouds in the atmosphere of the planet
of this telescope will allow us to peer through the clouds on planets like GJ 1214b.

But the new addition to the catalogue of 800-plus exoplanets stands out in at least one major respect#it is far smaller than any planet yet discovered outside of our solar system.
"What makes this very interesting is this is a planet smaller than anything we see in our own inner solar system,
The researchers used NASA s Kepler space telescope to identify the three planets orbiting Kepler 37, a star some 200 light-years away that is somewhat smaller than the sun. The spacecraft monitors more than 150,000 stars in the Milky way
or dips in brightness, that might be caused by a planet passing in front of its star, from the probe s perspective.
The Kepler mission has discovered already more than 100 new planets since its launch in 2009 and has identified thousands of additional candidates that await confirmation.
Planets smaller than Earth block relatively small amounts of starlight which limits astronomers ability to detect them with Kepler.
By observing the planet Kepler 37 b as it transited, or passed in front of its star, more than 50 times,
Every 13 days or so the star dimmed by a tiny fraction#just 0. 002 percent#as the tiny planet passed across the star s face.

Whereas giant Jupiter-size planets often exert a gravitational tug on their host stars that is detectable with Earth-based telescope spectrographs,

#Cool planet hints at potential for life in double stars It's a cool planet in a tight spot.
A frigid world about 3000 light years away offers the first evidence that rocky planets can form in Earthlike orbits even
Although this planet probably cannot support life as we know it the discovery greatly expands the places we can look for potentially habitable worlds outside our solar system.
Astronomers have found a handful of planets that orbit both partners in close binary pairs.
But no one was convinced that a planet could orbit just one star at a sufficient distance to host life.
and the sun. The team found a planet about twice the mass of Earth orbiting just one of the two stars at about the same distance as we are to our home star.
and the further it is from the star the more difficult it would be for planets to form.
But this discovery argues that yes indeed at least in this system of two red dwarfs you can form planets at these sorts of longer distances says Gaudi.
Jean-Philipe Beaulieu at the Paris Institute of Astrophysics in France called the newfound planet an important discovery.
While the planet is most likely rocky based on its mass its surface is a frigid-213°C That's
But the same planet orbiting a sun-like star in a binary system would be in the habitable zone where conditions could support liquid water
Gaudi's co-author Andrew Gould also at OSU says his team's evidence for the existence of their frozen planet is airtight.
Microlensing detects planets by watching how their gravity affects the light of a distant background star.
But if the foreground star hosts a planet the world's gravity can sometimes eliminate one of these images.
The planet isn't blocking the background star's light. It's just that the mathematics of focusing is disrupted by the planet's gravity he says.
There's absolutely no doubt that what we've detected is a rocky planet in a binary star system adds Gould.
Ten thousand years from now people will go visit this system and find out that it's exactly
In the case of the planet announced by Gould's team stellar variability could not mimic the observed signal.
About 515 million years ago our planet was going through an evolutionary slump. A burst of diversity that happened during the Cambrian period had tapered off
But it could later switch to satellites like the 28 imaging cubesats that the firm Planet Labs of San francisco already has in orbit.
Planet Labs ultimately wants a fleet of 100 of the tiny satellites enough to refresh its imagery of the entire planet once a day says Arin Jumpasut a Planet Labs imaging engineer.
when life was emerging our young planet had an atmosphere oceans and primordial continents. But it did not yet have an ozone layer to shield the surface from the sun's harshest ultraviolet rays.
so Pontefract thinks impacts could have helped kick-start life on rocky planets and then shielded whatever emerged.
Crater rocks could provide refuges even now for life on other planets such as Mars she says.
#Impossibly heavy planet is the first'mega-Earth'Sly Stallone has nothing on this rocky heavyweight.
Twice the size of Earth and with 17 times our planet's mass Kepler-10c is so unusual that it has been placed in a brand new class of exoplanet.
The planet orbits a star that is about 560 light years away from us. It has a radius slightly more than double that of Earth's a size that led astronomers to assume it was a shrunken version of gassy planet Neptune
which is four times larger than Earth. Now Xavier Dumusque of the Harvard-Smithsonian Center for Astrophysics in Cambridge Massachusetts and his colleagues have used the HARPS-N telescope in the Canary islands to pin down Kepler-10c's mass.
All the major existing planetary formation models were not predicting this type of planet and it is why we could not believe our result at the beginning says Dumusque who presented the findings at the American Astronomical Society meeting in Boston this week.
Calculations by geophysicists previously suggested that gravity should compress planets so much that rocky worlds can't get bigger than twice Earth's size says Kepler team member Geoff Marcy at the University of California Berkeley.
This suggestion of a rocky planet 2. 3 times the size of Earth blows me away he says.
which would be the physical limit for planets he says. Neighbouring planet Kepler-10b was already famous among planet hunters for being confirmed the first rocky world outside our solar system.
But it is very close to its star completing a full orbit in just 20 hours.
The more we find planets outside the solar system the more we are surprised by the diversity of these new worlds says Dumusque e
For the first time satellites and ground-based detectors have watched as the planet sends out a tendril of plasma to fight off blasts of charged solar matter.

A fleet of Cubesats with propulsion in orbit around a planet or moon can do a lot of things that big expensive satellites cannot, such as monitoring several locations in the atmosphere at once.
MOM should also help to unravel some of the planet's mysteries. It will carry five scientific instruments including a methane sensor to try to pick up the gas in Mars's atmosphere.

A physical simulation of a comet's impact with a planet shows that the conditions are extreme enough to create amino acids within the comet's ice.
Then they shot the ice with a steel pellet travelling at about 7 kilometres a second to simulate the comet smacking into a planet
This is a neat way of suggesting prebiotic material could be produced regardless of the external conditions of the planet says Goldman.
You could have a planet that isn't really conducive to forming amino acids like early Earth supposedly wasn't he says.

It will deploy Sprint-A into low Earth orbit where the spacecraft will take aim at the planets using cameras and sensors that record extreme-ultraviolet light.
Extreme UV from the sun gets bent at the boundary where a planet's atmosphere meets space

which can ionise gases in a planet's upper atmosphere and pick up the newly charged particles effectively sweeping them away.
Because Venus is closer to the sun the solar wind might have stripped gaseous water from its early atmosphere leaving a thick haze of mostly carbon dioxide that turned the planet's surface into a hellish desert.
By observing this phenomenon we will investigate how the solar wind affects the upper atmosphere of planets and how the planetary atmosphere escapes into outer space.
Until recently a planet's habitability was defined largely by its distance from its star which hints at
