A pair of satellites flying in close formation to cast an artificial eclipse is now being turned into space-ready reality by ESA’s industrial partners.
SPHERE — the Spectro-Polarimetric High-contrast Exoplanet REsearch instrument — has been installed on ESO’s Very Large Telescope (VLT) at the Paranal Observatory in Chile and has achieved first light.
Comet ISON, hailed as the “comet of the century” by space enthusiasts and armchair astronomers, was apparently done in during its final approach to the sun, according to media reports published Thursday.
As Comet ISON heads toward its closest approach to the sun — known as perihelion — on Nov. 28, 2013, scientists have been watching through many observatories to see if the comet has already broken up under the intense heat and gravitational forces of the sun.
On Thanksgiving Day, Nov. 28, 2013, Comet ISON will finally sling shot around the sun. Here its inward journey through the solar system will end -- either because it will break up due to intense heat and gravity of the sun, or because, still intact, it speeds back away, never to return.
Lockheed Martin, under a contract from the University of Arizona, has completed assembly and testing of the Near Infrared Camera (NIRCam) and has shipped the instrument to the NASA Goddard Space Flight Center in Greenbelt, Md.
In the search for life beyond Earth scientists face significant challenges. Given the great distances and faint signatures of the alien worlds that we have found, discovering which ones are even potentially habitable is difficult.
When the Solar and Heliospheric Observatory (SOHO) launched on Dec. 2, 1995, it provided some of the first high-resolution observations of the sun unobscured by Earth's own atmosphere.
A new study suggests that the nearby star Fomalhaut hosts a massive "zombie" exoplanet that was previously thought to not exist, but is back from the dead.
Terrestrial Planet Finder -- The Terrestrial Planet Finder is a proposed NASA telescope system capable of detecting extrasolar terrestrial planets. In May 2002, NASA chose two TPF mission architecture concepts for further study and technology development. Each would use a different means to achieve the same goal - to block the light from a parent star in order to see its much smaller, dimmer planets. That technology challenge has been likened to finding a firefly near the beam of...
- Having no light.
- Of or relating to the region of a body of water that is not reached by sunlight and in which photosynthesis is unable to occur.
