A planet close to its parent star is hot like Venus, but rotates quickly and could have a substantial atmosphere.

The Halloween 'dead comet' spooked the world with its abrupt appearance, why didn't we know about it earlier?

A new test for defining the planetary status of an exoplanet has been formulated, but a certain dwarf planet in our solar system still doesn't make the planetary grade.

The collection of rocky planets orbiting distant stars has just grown by one, and the latest discovery is the most intriguing one to date. The newfound world, although hot as an oven, is cool enough to potentially host a...

"We want the best relationship with our environment that we can achieve. That requires understanding," says Waleed Abdalati, the man tapped to co-chair the blue-ribbon panel that will tell NASA and NOAA which Earth scien...

Since the late 1980s, scientists have discovered nearly 5,000 planetary bodies orbiting stars other than the sun. But astronomers are still working on what exactly we should call them.

The Senate passed Nov. 10 the final version of a commercial launch bill that also provides limited property rights for resources extracted from asteroids.

A new machine-learning simulation system developed at the University of Illinois promises cosmologists an expanded suite of galaxy models - a necessary first step to developing more accurate and relevant insights into th...

A newly discovered planet is being called the closest Earth-size planet ever discovered, possibly providing the mouth-watering opportunity for a close-up look at the atmosphere of a rocky body around another star.

Astronomers have found what may be the oldest stars in the Milky Way, in the galaxy's bulge -- a discovery that reveals extraordinarily powerful explosions known as hypernovas might have dominated the Milky Way during it...

The closest rocky planet (GJ1132b) like our Earth has been discovered, 40 light years out - revolving close in to an M-dwarf star about half the size of our Sun. It was uncovered by the MEarth-South telescope array on Ce...

Scientists have discovered a new exoplanet that, in the language of "Star Wars," would be the polar opposite of frigid Hoth, and even more inhospitable than the deserts of Tatooine. But instead of residing in a galaxy fa...
