NASA Telescope Confirms Alien Planet in Habitable Zone

NASA/Ames/JPL-Caltech

-- NASA's Kepler spacecraft has detected more than 1,000 new alien planet candidates, and confirmed its first exoplanet in its host star's habitable zone. The finds bring the number of potential exoplanets discovered by the space telescope to more than 2,000. [Read More]

Mystery of Mars Gullies Solved

NASA/JPL/Malin Space Science Systems

New research reveals that Martian polar gullies could have formed without the presence of liquid water on their surface. Instead, the sublimation of carbon dioxide could have been responsible for the formations on the red planet. [Read More]

Meteor Crater Helps Unlock Planetary History

NASA

The Barringer meteorite crater – known popularly as “Meteor Crater” near Winslow, Ariz., is a prime example of a space rock impact site, and is being used by scientists to study the mechanics of impacts throughout the universe. [Read More]

Quintet

Stephan's Quintet, in the constellation Pegasus, consists of five galaxies, although one lies closer than the others. Japan's Subaru Telescope shows two views of the grouping using different filters to distinguish the recession velocity of each object, the speed at which the object moves away from the observer. The image on the left shows the galaxies filtered for a recession velocity of 0, while the one on the right shows them filtered for a recession velocity of 4,200 miles per second. The contrasting images show that NGC7320 (lower left) is closer than the other galaxies. [See more amazing space images]
