NASA’s Hubble Space Telescope and the W.M. Keck Observatory in Hawaii have made independent confirmations of an exoplanet orbiting far from its central star. The planet was discovered through a technique called gravitational microlensing. This finding opens a new piece of discovery space in the extrasolar planet hunt: to uncover planets as far from their central stars as Jupiter and Saturn are from our sun. The Hubble and Keck Observatory results will appear in two papers in the Jul...

Using NASA's Spitzer Space Telescope, astronomers have confirmed the discovery of the nearest rocky planet outside our solar system, larger than Earth and a potential gold mine of science data. Dubbed HD 219134b, this exoplanet, which orbits too close to its star to sustain life, is a mere 21 light-years away. While the planet itself can't be seen directly, even by telescopes, the star it orbits is visible to the naked eye in dark skies in the Cassiopeia constellation, near the North Star. ...

Lockheed Martin (NYSE:LMT) engineers have successfully completed testing of design changes made to the NASA Orion spacecraft's fairing separation system. These changes resulted from data collected during Orion's first test flight on Dec. 5, 2014. A finished Orion spacecraft has three fairings, or panels, that protect the service module radiators and solar arrays from heat, wind and acoustics during ascent into space. For the purposes of collecting data during these tests, only one fairing was...

The chemical element lithium has been found for the first time in material ejected by a nova. Observations of Nova Centauri 2013 made using telescopes at ESO's La Silla Observatory, and near Santiago in Chile, help to explain the mystery of why many young stars seem to have more of this chemical element than expected. This new finding fills in a long-missing piece in the puzzle representing our galaxy's chemical evolution, and is a big step forward for astronomers trying to understand the amount...

A fast-moving pulsar appears to have punched a hole in a disk of gas around its companion star and launched a fragment of the disk outward at a speed of about 40 million miles per hour. NASA’s Chandra X-ray Observatory is tracking this cosmic clump, which appears to be picking up speed as it moves out. The double star system PSR B1259-63/LS 2883 – or B1259 for short – contains a star about 30 times as massive as the Sun and a pulsar, an ultra-dense neutron star left behi...

Flowing ice and a surprising extended haze are among the newest discoveries from NASA's New Horizons mission, which reveal distant Pluto to be an icy world of wonders. "We knew that a mission to Pluto would bring some surprises, and now -- 10 days after closest approach -- we can say that our expectation has been more than surpassed," said John Grunsfeld, NASA's associate administrator for the Science Mission Directorate. "With flowing ices, exotic surface chemistry, mountain ranges, and vast...
