Researchers are using basalt spectra to study exoplanets and search for water with the James Webb Space Telescope. By studying chemical processes in the Earth's hot mantle, Cornell scientists are ...

The faraway exoplanet could help provide answers as to why there are hardly any planets with twice the diameter of Earth.

GJ 9827 d, an exoplanet akin to Neptune, was discovered in 2017. It has a diameter twice the size of Earth and is estimated to be much heavier, with a mass approximately 3.5 times that of our planet.

We don’t know for sure, but the answer is inextricably linked to the moment when water first materialized in the cosmos — and ...

Astronomers have discovered two new exoplanets that are similar to other worlds found in the Milky Way, but unlike any in our ...

Water has been discovered for the first time in the atmosphere of an exoplanet with Earth-like temperatures that could support life as we know it, scientists revealed on Wednesday. Eight times the ...

Astronomers, utilizing NASA's Hubble Space Telescope have identified water molecules in the atmosphere of GJ 9827d, a small exoplanet located 97 light-years away from Earth. The detection of water ...

Are we alone in the universe? While no one can say for sure, space scientists know where to start looking—exoplanets. An ...

In October 1995, after decades of serious effort, astronomers announced the first discovery of a planet orbiting a Sun-like star. Until then, the few planets known to exist beyond the solar system ...
