'As the number of exoplanets we've discovered increases, the question about life existing somewhere other than the Earth remains.'

The molten planet, with an atmosphere rich in sulfur-bearing gases, is unlike anything astronomers have ever smelled.

Despite the universe's vastness, containing billions of stars and galaxies, humanity has yet to encounter alien life. Scientists are actively searching for habitable planets and signs of life, but the immense distances and the possibility of life forms vastly different from our own present significant challenges.

Life on Earth is a precious thing, especially given what astronomers know about the visible universe. Although researchers have so far identified over 6,000 exoplanets beyond our solar system, only a handful of them may be suitable for human visitors.

Out of the 6,000 known exoplanets, it's these rocky worlds that are most worthy of attention in the search for life beyond our planet.

Astronomers have discovered a strange new world just 35 light-years from Earth – one permanently covered in a vast ocean of molten rock. The exoplanet, known as L 98-59 d, defies existing models of planetary formation and may represent an entirely new class of planet,

Talk about a hot mess. Scientists have uncovered a hellish “lava world” where temperatures soar to a blistering 2,700 degrees Fahrenheit — hot enough to melt rock into a churning ocean of magma and fill the air with the stench of rotten eggs.

Exoplanet TOI-561 b is the closest of four worlds orbiting a 10-billion-year-old G-type star roughly 280 light-years from Earth. - NASA / ESA / CSA / Ralf Crawford illustration NASA’s James Webb Space Telescope has found the strongest evidence yet that a ...
