  • In Pictures Space photos of the day: Mergers and acquisitions

    This Hubble composite shows 12 views of galaxies colliding, dramatically illustrating how galactic collisions produce a remarkable variety of intricate structures in never-before-seen detail.

  • In Pictures Space photos of the day: Exoplanets

    This is an artist's concept of a gas giant planet orbiting the cool, red dwarf star Gliese 876, located 15 light-years away in the autumn constellation Aquarius. The planet was discovered in 1998. But new Hubble Space Telescope measurements of the star's wobble, caused by the gravitational tug of the planet, firmly establish the planet's mass as being no more than approximately twice that of Jupiter's.

  • In Pictures Space photos of the day: Space Shuttle Discovery

    In this image provided by NASA, the Space Shuttle Discovery is seen from the International Space Station as the two orbital spacecraft accomplish their relative separation on March 7, after an aggregate of 12 astronauts and cosmonauts worked together for over a week. The area below is the southwestern coast of Morocco in the northern Atlantic.

    Final shuttle launch for Discovery: Was shuttle program worth it?

    For 30 years, the space shuttle launch has served as the centerpiece of the US space program. But Feb. 24 will mark the last shuttle launch of Discovery, with the final flight of Endeavour to follow in April and – if there's enough money – Atlantis's last flight of the entire program in June. Here are five questions about what the shuttles have – and haven't – accomplished.

  • In Pictures Exploring Mars with rovers Curiosity and Opportunity

    Mars’ northern-most sand dunes are seen as they begin to emerge from their winter cover of seasonal carbon dioxide (dry) ice in this image acquired by the HiRISE camera aboard NASA's Mars Reconnaissance Orbiter Jan. 16, 2014. The steeply sides of the dunes are also ice-free along the crest, allowing sand to slide down the dune. Dark splotches are places where ice cracked earlier in spring, releasing sand.

    Stardust-NExT to make Valentine rendezvous with comet Tempel 1

    NASA sent its Deep Impact probe to comet Tempel 1 in 2005, but failed to get the data it wanted. Now, with Stardust-NExT returning this Monday, NASA gets a second shot.

  • In Pictures Space photos of the day: Infrared

    On Oct. 9, 1604, sky watchers, including astronomer Johannes Kepler, spotted a 'new star' in the western sky, rivaling the brilliance of nearby planets. 'Kepler's supernova' was the last exploding supernova seen in our Milky Way galaxy. Observers used only their eyes to study it, because the telescope was not yet invented. Now, astronomers have utilized NASA's three Great Observatories to analyze the supernova remnant in infrared, optical and X-ray light.

  • In Pictures Space photos of the day: In Technicolor

    The NASA image captured by the Hubble Space Telescope on Aug. 10, 2008 shows a small portion of the Tarantula nebula near the star cluster NGC 2074. The region is a frontier of raw stellar creation, perhaps triggered by a nearby supernova explosion. It lies about 170,000 light-years away from Earth and is one of the most active star-forming regions in our local group of galaxies.

    Oldest galaxy: Hubble telescope detects farthest, oldest galaxy yet

    Oldest galaxy: Astronomers using the Hubble telescope have detected a galaxy that formed just 500 million years after the Big Bang, making it the most distant and oldest galaxy discovered so far.

  • In Pictures Space photos of the day: Cosmic pairs

    A new Hubble Space Telescope image of a celestial object called the Ant Nebula may shed new light on the future demise of our Sun. The Ant Nebula, whose technical name is Mz3, resembles the head and thorax of an ant when observed with ground-based telescopes. The new Hubble image, with 10 times the resolution revealing 100 times more detail, shows the 'ant's' body as a pair of fiery lobes protruding from a dying, Sun-like star. The Ant Nebula is located between 3,000 and 6,000 light years from Earth in the southern constellation Norma.
