The challenge was the observation of effect occurred during the transit of Venus across the Sun on June 6th, dubbed "Rossiter-McLaughlin effect". This is a phenomenon that occurs when a celestial body passes in front of a star, hiding a part of its rotating surface and that produces a temporary distortion in the profiles of the spectral lines of light coming from the eclipsed star.
The United States Air Force Space and Missile Systems Center has awarded SpaceX two Evolved Expendable Launch Vehicle (EELV)-class missions: DSCOVR (Deep Space Climate Observatory) and STP-2 (Space Test Program 2)
A team of astronomers led by the University of Leicester has uncovered new evidence that suggests that X-ray detectors in space could be the first to witness new supernovae that signal the death of massive stars.
Forty years after the last Apollo spacecraft launched, the science from those missions continues to shape our view of the moon. In one of the latest developments, readings from the Apollo 14 and 15 dust detectors have been restored by scientists at NASA
NGC 922's current unusual form is a result of a cosmic bullseye millions of years ago. A smaller galaxy, catalogued as 2MASXI J0224301-244443, plunged right through the heart of NGC 922 and shot out the other side.
A Cornell-based project called KickSat is set to launch more than 200 tiny satellites, nicknamed "sprites," into low-Earth orbit as part of a routine NASA-administered mission in 2013 to the International Space Station.
By combining the observing powers of ESA's Herschel space observatory and the ground-based Keck telescopes, astronomers have characterised hundreds of previously unseen starburst galaxies, revealing extraordinary high star-formation rates across the history of the Universe.
Scientists have long suspected that a vast ocean of liquid water lies under the crusty exterior of Titan, Saturn's largest moon. New analysis suggests that the internally generated heat that keeps that ocean from freezing relies on the moon's interactions with Saturn and its other moons.
