  • In Pictures Space photos of the day: Dancing with the Stars

    Two galaxies perform an intricate dance in this new Hubble Space Telescope image. The galaxies, containing a vast number of stars, swing past each other in a graceful performance choreographed by gravity. The pair, known collectively as Arp 87, is one of hundreds of interacting and merging galaxies known in our nearby universe. Arp 87 is in the constellation Leo, the Lion, approximately 300 million light-years away from Earth. These observations were taken in February 2007 with the Wide Field Planetary Camera 2.

    The primordial haze theory competes with the primordial soup theory in a new scientific debate.

  • In Pictures Space photos of the day: Gas giants

    This image provided by NASA's Hubble Space Telescope Thursday May 4, 2006 shows a second red spot (lower l.) emerging on Jupiter. For the first time in history, astronomers have witnessed the birth of a new red spot on the giant planet, which is located half a billion miles away. The storm is roughly one-half the diameter of its bigger and legendary cousin, the Great Red Spot. Researchers suggest that the new spot may be related to a possible major climate change in Jupiter's atmosphere.

  • In Pictures Space photos of the day: Voyager

    Seen here is a full-scale model of one of the twin Voyager spacecraft, which was sent to explore the giant outer planets in our solar system. Voyager 2 was launched August 20, 1977 followed by the launch of Voyager 1 sixteen days later. Both spacecraft visited Jupiter and Saturn with Voyager 2 continuing its journey to Uranus and Neptune. In spring 1990, Voyager 2 transmitted images looking back across the span of the entire solar system. Both Voyagers continue to explore interstellar space.

    This false-color image shows the incredible, complex beauty of Saturn's rings. The massive ring system is over 150,000 miles in diameter.

    How Titan might be making DNA building blocks

    Saturn's moon Titan has many of the components for life – but no liquid water. A new study shows how the moon's atmosphere might be producing the molecules that make up DNA anyway.

    The moon as solar system's Rosetta stone?

    New research suggests that two distinct groups of objects battered the surface of the moon – and could give clues into the early days of Earth's solar system.

    This is a Space Shuttle mission STS-61 onboard view showing astronauts Story Musgrave and Jeffrey Hoffman preforming repairs to the Hubble Space Telescope during their Extra Vehicular Activity. Astronauts' work was made easier by the HST's many crew aids. Astronaut Musgrave makes use of one of the spacecraft's handholds. Launched on December 1, 1993, the Space Shuttle Orbiter Endeavor STS-061 mission was the 59th Shuttle flight.

    This ominous, dark shape sprawling across the face of the Sun is a coronal hole - a low density region extending above the surface where the solar magnetic field opens freely into interplanetary space. Studied extensively from space since the 1960s in ultraviolet and x-ray light, coronal holes are known to be the source of the high-speed solar wind, atoms and electrons which flow outward along the open magnetic field lines. During periods of low activity, coronal holes typically cover regions just above the Sun's poles.
