How many stars like our sun host planets like our Earth? NASA’s Kepler Space Telescope continuously monitored more than 150,000 stars beyond our solar system, and to date has offered scientists an assortment of more than 4,000 candidate planets for further study -- the 1,000th of which was recently verified.
NASA's Kepler mission announced the discovery of 715 new planets. These newly-verified worlds orbit 305 stars, revealing multiple-planet systems much like our own solar system.
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.
More than 50 teachers, students and astronomy educators from the NASA/IPAC Teacher Archive Research Program (NITARP) will be attending the winter meeting of the American Astronomical Society (AAS).
Nine NITARP alumni educators, some of their current students, and a student alumna have all returned this year to AAS, paying their own way to attend the international conference.
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.
