New Study Reassesses Habitability of Exoplanets Around Multiple Star Systems

An artist’s concept of Kepler-47, which was the first-ever planetary system to be discovered orbiting a binary star. A new research that was based on data taken with NASA’s Hubble Space Telescope provides stringest limits to the potential habitablity of exoplanets in several such systems.

The exploration of the outer Solar System has revealed a plethora of amazing worlds, the likes of which […]

New Horizons Mission Returns First Images of Pluto's Smallest Known Moons Kerberos and Styx

NASA’s New Horizons spacecraft has just returned the first long-range images of Kerberos and Styx, the two smallest moons of Pluto. Each animation consists of five 10-second frames which were taken with the onboard LORRI camera between April 25 and May 1At left is the initial set of raw images, while at the center […]

Scientists have discovered a vast network of salty aquifers beneath the surface of Antarctica, thanks to an airborne imaging system used there for the first time. The finding may have interesting implications for the […]

Shedding New Light On the Solar System: Celebrating 25 Years of Hubble Science (Part 2)

A series of images of Uranus and Neptune that were taken with the Hubble Space Telescope. The top row reveals the ice giant planets in natural colors, showing the planets as they would appear if we could see them through a telescope. The images at the bottom were taken with certain types of different […]

The Dawn spacecraft is now very close to the dwarf planet Ceres, but there are some interesting new findings from its previous visit to the asteroid Vesta. Curved gullies on its surface suggest that small amounts of water may […]

Surprisingly Bright Cloud Systems and Extreme Storms on Uranus Puzzle Astronomers

Infrared images of Uranus at wavelengths of 1.6 (left) and 2.2 microns (right), that were obtained on Aug. 6, with the Adaptive Optics system on the 10-meter Keck II telescope on Mauna Kea in Hawaii. The white spot is an extremely large storm that was brighter than any feature ever recorded on the planet […]
