WELCOME to Mars – where the air is too thin to breathe and the surface temperature is too cold for unsheltered life. Yet the ...

For the better part of a century, we believed there were nine planets in our solar system, with Pluto being the farthest from the sun. Since the discovery of more Pluto-sized dwarf planets, that ...

Melva Hardison was born in Tennessee and raised near Florence, Alabama. She began working at a family cafe when she was 12. She was raised by her aunt. She had other odd jobs in the mostly rural ...

Why was Pluto reclassified as a dwarf planet? One might think that it’s purely a matter of size. Mercury, the smallest of the major planets, has a diameter that is twice as large as Pluto’s.

This planet, five times larger than Earth, has extreme temperatures reaching 2,400°C and could contain significant quantities of diamonds. This discovery challenges our understanding of planetary ...

The nearest single star to the sun, Barnard’s star, has a brood of planets all its own. The red dwarf star, about six light-years from Earth, hosts four close-in planets each about two to three ...

"There really is something very different about how these giant planets form versus how small planets like Earth form." Scientists have used data from NASA's retired planet-hunting space telescope ...

A combination of the world's most powerful telescopes detected the planets. Astronomers have confirmed the existence of four planets orbiting a star less than 6 light-years away with help from ...

The four planets are classified as sub-Earths because each one is about 19% to 34% the mass of Earth, according to new research. “It’s a really exciting find — Barnard’s Star is our cosmic ...

Now, four small planets have been found orbiting the star. Teams in America and Europe achieved this challenging detection by exploiting precision instruments on the world's largest telescopes.

This graph shows a spectrum of one of the planets in the HR 8799 system, HR 8799 e, which displays the amounts of near-infrared light detected from the planet by Webb at different wavelengths ...

For a century, astronomers have been studying Barnard’s Star in the hope of finding planets around it. First discovered by E. E. Barnard at Yerkes Observatory in 1916, it is the nearest single star ...
