NASA's Exoplanet Excursions virtual reality app, takes users on
a guided tour of the TRAPPIST-1 planetary system.
The Exoplanet Gliese 1132b is categorized as a super earth,
because it looks like our own planet.
Trying to measure the atmospheric composition of an Exoplanet passing in front of its host star is hard.
Astronomers have found
water for the first time in atmosphere of habitable Exoplanet K2-18b which orbits in its star's“habitable zone”.
In principle, an Exoplanet with an ozone layer that covers only the equatorial
region may still be habitable," Carone explains.
With each impact stripping off a different percentage of the atmosphere,
collisions can create a wide variety of Exoplanet densities.
In principle, an Exoplanet with an ozone layer that covers only the equatorial
region may still be habitable,” Carone said.
Red dwarfs are
considered to be the best places to look for Exoplanet candidates, which are planets outside our Solar System.

A colonization ship with more than 2000 people on board is on its way to an Exoplanet.
Ross 128 b is a confirmed Earth-sized Exoplanet, likely rocky,
orbiting within the inner habitable zone of the red dwarf Ross 128.
An international team of scientists has discovered a cold‘super-Earth' Exoplanet orbiting around the red dwarf Barnard,
the second closest star system to Earth.
We were surprised to see an Exoplanet with the same high density,

Astronomers explore the atmosphere by
analyzing the light from the host star when the Exoplanet is in front of it or is passing by.
Called 51 Pegasus b, the Exoplanet is not habitable either, but
it challenged our understanding of planets and laid the foundation for future discoveries.
Barnard's Star b(also designated GJ 699 b)

This is not the first time that water
vapor has been detected in the atmosphere of an Exoplanet, but the previous discoveries concerned gaseous giants.
Normally the light of the star around which an Exoplanet revolves is so powerful that the light
that the planet itself reflects is beamed through it.

Lunau At 1040 light-years away from the earth, the Exoplanet HAT-P-7b sparkles with clouds of rubies and sapphires.
Aside from the tremendous distance separating Earth from K2-18b, the Exoplanet is likely exposed to far more radiation than Earth,
diminishing the prospects for life evolving there.
With a day-side temperature peaking at
4,326 degree Celsius the newly discovered Exoplanet, designated KELT-9b,
is hotter than most stars and only 926 degree Celsius cooler than our Sun.
But it was follow-up observations from another orbiting instrument, the Spitzer Space Telescope,
which can detect infrared light directly from an Exoplanet, that provided new insights about its features.
