The most detailed images yet of Pluto, taken by the Hubble Telescope, reveal a yellow-black sphere whose surface appears to be among the most dynamic in the solar system.
In this image provided by NASA, the space shuttle Endeavour is ferried by NASA's Shuttle Carrier Aircraft (SCA) over the Kennedy Space Center in the early morning hours of Sept. 19, 2012, as it departs for California.
Astronomers have long suspected that objects in the main asteroid belt -- between Mars and Jupiter -- collide. Now they have what could be direct evidence.
New Hubble telescope images provide a look at the cosmos when it was just 600 to 800 million years old. Galaxies from this period might have helped transform the universe from dark to light.
This Hubble Space Telescope image of Eta Carinae, a star in the constellation Carina, is 50 light-years wide and was made of a composite of 48 frames.
The successful space shuttle launch Monday marks an important shift for the shuttle program. From Atlantis onward, the shuttles' primary job is to ferry large parts to the International Space Station.
An artists rendering image shows an exoplanet 6 times the Earth circulate around its low-mass host star at a distance equal to 1/20th of the Earth-Sun distance. European astronomers announced they had found 32 new planets orbiting stars outside our solar system on Monday. They believe their find means that 40 percent or more of Sun-like stars have such planets. The host star in this image is a companion to two other low-mass stars, seen in the distance.
The Orion spacecraft will replace the Space Shuttle as a part of the Constellation program, an effort to gain proficiency and experience operating away from Earth's environment and to land human explorers on the moon by 2020. The Orion will carry four to six astronauts and will be the NASA's primary vehicle for manned spaceflight missions. Orion's first scheduled flight will be in September 2014.
Two pieces of a NASA spacecraft – not bombs – will crash into the moon early Friday morning, hoping to kick up evidence of water ice at the bottom of a frigid south pole crater.
This image of the Antennae galaxies is the sharpest yet of this merging pair of galaxies. During the course of the collision, billions of stars will be formed. The brightest and most compact of these star birth regions are called super star clusters. The two spiral galaxies started to interact a few hundred million years ago, making the Antennae galaxies one of the nearest and youngest examples of a pair of colliding galaxies.
