NASA's 23-year-old Hubble Space Telescope is still going strong, and agency officials said Tuesday (Jan. 8) they plan to operate it until its instruments finally give out, potentially through 2018, space agency officials say. [Read the Full Story]
This artist's illustration shows the atmosphere of a brown dwarf called 2MASSJ22282889-431026, which was observed simultaneously by NASA's Spitzer and Hubble space telescopes. The telescopes' observations indicate this brown dwarf is marked by wind-driven, planet-size clouds. [Read the Full Story]
This artist's concept shows the brown dwarf 2MASSJ22282889-431026, which has a turbulent atmosphere somewhat similar to the giant planet Jupiter's. [Read the Full Story]
This false-color composite image, taken with the Hubble Space Telescope, reveals the orbital motion of the planet Fomalhaut b. Based on these observations, astronomers calculated that the planet is in a 2,000-year-long, highly elliptical orbit. Image released Jan. 8, 2013.

This diagram shows the orbit of the exoplanet Fomalhaut b as calculated from recent Hubble Space Telescope observations. The planet follows a highly elliptical orbit that carries it across a wide belt of debris encircling the bright star Fomalhaut. Image released Jan. 8, 2013.

NASA's planet-hunting Kepler space observatory has discovered 461 new potential alien planets, boosting its total to 2,740 potential extrasolar worlds. [Full Story]
Attendees of the American Astronomical Society Meeting in Long Beach, CA, were treated to a colorful sunset on Jan. 7, 2013.
This NASA graphic depicts the changes in alien planet discoveries, arranged by planet size, as seen by NASA's Kepler spacecraft. As of Jan. 7, 2012, there are 2,740 potential alien planets. [Full Story]

This artist's illustration represents the variety of planets being detected by NASA's Kepler spacecraft. Scientists now say that one in six stars hosts an Earth-size planet. [Full Story]
Infographic: Practically all sun-like stars have planets, and one in six has a planet the size of Earth, a new study finds. [Full Story and larger image]
This chart depicts the frequencies of planets based on findings from NASA's Kepler space observatory. The results show that one in six stars has an Earth-sized planet in a tight orbit. [Full Story]
The widest binaries and triple systems have very elongated orbits, so the stars spend most of their time far apart. But once in every orbital revolution they are at their closest approach. They may pose a danger to any planets orbiting them.
