The habitable zone is partly defined by the range of temperatures generated by heat from the star. The zone is located at a ...

In 2003, Hubble found a massive exoplanet. There's nothing too unusual about that, but closer inspection revealed the planet, called PSR B1620-26b, to be quite weird.

NASA's Hubble Space Telescope and New Horizons spacecraft simultaneously set their sights on Uranus recently, allowing scientists to make a direct comparison of the planet from two very different ...

Hubble's image sharpness is comparable to the Voyager views as they approached the outer planets, and Hubble spans wavelengths from ultraviolet to near-infrared light.

NASA is releasing stunning photos taken by the Hubble Space Telescope to celebrate its 35th anniversary. Check them out below.

The Hubble Space Telescope has been imaging the outer planets of our solar system for a decade, learning about their strange weather conditions.

Hubble has observed several of those protoplanetary disks with planets plowing through them, but it’s not clear why Vega’s disk is void of any form of a planetary body.

Astronomers using the Hubble Space Telescope have for the first time directly detected the atmosphere of a planet outside our solar system. The unique observation shows it may be possible to find ...

Astronomers for the first time have observed the atmosphere of a planet circling a distant star, opening the possibility of more comprehensive searches for the chemical markers of life on distant ...
