NASA says it has successfully administered multiple tests to a new instrument on the Nancy Grace Roman Space Telescope, which will allow unprecedented views of planets beyond our solar system.
A team of NASA researchers says they have identified 17 potentially habitable icy worlds including two that are cosmically nearby, which may have subsurface oceans teeming with extraterrestrial life.
New simulations by California astrophysicists reveal that gas giant planets can act as 'agents of chaos' by wreaking havoc on the orbits of earthlike planets capable of supporting alien lifeforms.
Whether one is inspired by recent UAP news, or advances in space exploration, many believe that extraterrestrial intelligence exists. How soon might we finally discover it?
A Spanish researcher who has previously discovered water, carbon dioxide and other key life-supporting chemicals in an interstellar region of space where planets and stars are born says she has now found the life-supporting amino acid tryptophan in the same place.
A new study examining the orbital eccentricity of exoplanets has determined that as many as 1 in 3 planets orbiting the billions of M-dwarf stars in the Miky Way galaxy may be habitable.
For the first time ever, researchers using the James Webb Space Telescope have successfully measured the light coming from a sub-Neptune-sized exoplanet that orbits a star only 40 light years away.
A new paper from the University of Tokyo suggests that astrobiologists could find signs of alien life in particles of space dust that have been ejected from exoplanets and traveled across the vastness of space to reach earth.
