NASA's Kepler mission has discovered two new planetary systems that include three super-Earth-size planets in the "habitable zone," the range of distance from a star where the surface temperature of an orbiting planet might be suitable for liquid water.

NASA's Kepler space telescope has witnessed the effects of a dead star bending the light of its companion star. The findings are among the first detections of this phenomenon -- a result of Einstein's theory of general relativity -- in binary, or double, star systems.

NASA's Kepler mission has discovered 11 new planetary systems hosting 26 confirmed planets. These discoveries nearly double the number of verified planets and triple the number of stars known to have more than one planet that transits, or passes in front of, the star. Such systems will help astronomers better understand how planets form.

Astronomers using data from NASA's Kepler mission have discovered the three smallest planets yet detected orbiting a star beyond our sun. The planets orbit a single star, called KOI-961, and are 0.78, 0.73 and 0.57 times the radius of Earth. The smallest is about the size of Mars.

NASA's Kepler mission has discovered the first Earth-size planets orbiting a sun-like star outside our solar system.

The Kepler team has discovered Kepler-22b, a planet 2.4 times the size of Earth that orbits a sun-like star in 289 days. It the smallest planet yet found to orbit in the middle of its star's habitable zone, which is the region around a star where temperatures are just right for liquid water, a key ingredient for life.

They say there is no place like home. For Caltech's George Helou, the essence of that phrase carries over to the recognition of his accomplishments. This past year, he has received numerous honors from Lebanon, his country of origin, including his election to the Lebanese Academy of Sciences. The tributes bestowed by the Mediterranean nation cite Helou's distinguished career in astronomy in the United States and Europe.

Our Milky Way galaxy contains a minimum of one planet for every star on average, according to a new statistical study.

Imagine you are a high school student walking into your science class in September and you learn that your teacher is doing research with NASA and you can actually participate This experience is occurring in schools around the US as more and more teachers become part of the NASA/IPAC Teacher Archive Research Program. 2012 marks the program's 8th year.

Today, astronomers unveiled the most complete 3-D map of the local universe (out to a distance of 380 million light-years) ever created. Taking more than 10 years to complete, the 2MASS Redshift Survey (2MRS) also is notable for extending closer to the Galactic plane than previous surveys - a region that's generally obscured by dust.

NASA announced Monday an $18.7 billion budget request for fiscal year 2012 that supports a reinvigorated path of innovation, technological development and scientific discovery. The budget supports all elements of NASA's 2010 Authorization Act, which was passed by a strong bipartisan majority of Congress and signed into law by President Obama.

The NASA/IPAC Teacher Archive Research Program class of 2011 was recently announced. A total of 12 educators hail from all over the United States including Arizona, California, Connecticut, Florida, Illinois, Kansas, Minnesota, Oregon, Pennsylvania, Virginia, and Wisconsin. The educators and their scientific mentors are divided into three teams that will perform research and prepare posters for the 2012 American Astronomical Society winter conference.
