NASA has yet to
find a habitable exoplanet, a planet where humans could live outside the solar system, but it has dedicated space telescopes probing the universe looking for suitable worlds.

He is also part of a NASA team that will soon be using the Transiting
Exoplanet Survey Satellite (TESS) to
find Earth - like planets orbiting in or near the
habitable zone of their stars.

find an
exoplanet that could be
habitable — and it's as close to us as it could possibly be

find signs of Gliese 581 g in their data, if its existence is confirmed, it will be the most

exoplanet finds to predict that the first
habitable Earth - like planet could turn up in May 2011.
The oldest detected Kepler planets (
exoplanets found using NASA's Kepler telescope) are about 11 billion years old, and the planetary diversity suggests that around other stars, such initially frozen worlds could be the size of Earth and could even provide
habitable conditions once the star becomes older.
The
findings have direct implications for future NASA missions, such as the Transiting
Exoplanet Survey Satellite and James Webb Space Telescope, which will try to detect possible
habitable planets and characterize their atmospheres.
Several new potentially
habitable exoplanets were
found, though none were precisely Earth - like.
I'm still holding out for the news that reads: «Second Earth
Found» -[this
exoplanet] will have all the right ingredients: orbit its star inside the
habitable zone, spectroscopic analysis will reveal a nitrogen - rich atmosphere, evidence of water, roughly the same mass as our planet and it will belong in a system with a couple of gas giants shepherding the outer system.
It will aid scientists in
finding the properties of host stars, their radii and masses, as well as in identifying the specific properties that make surrounding
exoplanets habitable.
As astronomers discover previously - unknown
exoplanets, many are especially interested in
finding worlds within the so - called
habitable zone around suns.
Five
exoplanets, two of which reside in the
habitable zone, have been
found orbiting the Sun - like star Tau Ceti.
If we can
find that life started independently twice in one solar system, that vastly increases the chances of life being on
habitable exoplanets.
So we might just have to send an interstellar probe there to
find out if Proxima b is really the
habitable exoplanet everyone hopes it will be.

exoplanet found so far that orbits within the «
habitable zone» of its star.

found a new
exoplanet orbiting Ross 128 that looks like the closest thing we've
found yet to a
habitable, Earth - like planet.
A recent paper submitted to the Astrophysical Journal by Sarah Ballard, an
exoplanet astronomer at MIT, estimated that TESS may
find as many as 1000 planets orbiting red dwarfs and around 15 of these may be less than twice the size of the Earth and orbit within the
habitable zone; ideal candidates for a JWST observation.
Students learn about the transit method for
finding planets and they use Kepler's 3rd law to determine whether the
exoplanet Kepler - 22b is
habitable.
Months ago, Rory Barnes, an astronomer at the University of Washington with a talent for
finding planets, agreed to give a plenary talk at the northwest sectional meeting of the American Physical Society on the subject of «The Hunt for
Habitable Exoplanets.»
To better understand factors affecting the range of
habitable conditions of
exoplanets, GISS climate modelers go back in time to simulate the «Snowball Earth» conditions of 720 to 635 million years ago and
find that complete freeze - over is hard to achieve.
