The destruction of a planet may sound like the stuff of science fiction, but a team of astronomers has found evidence that this may have happened in an ancient cluster of stars at the edge of the Milky Way galaxy.
Using several telescopes, including NASA’s Chandra X-ray Observatory, researchers have found evidence that a white dwarf star – the dense core of a star like the Sun that has run out of nuclear fuel – may have ripped apart a planet as it came too close.
Ariane Flight VA222
Arianespace's next Ariane 5 flight from the Spaceport is now scheduled for April 24. Under the new planning, liftoff will occur at 4:38 p.m. local time in French Guiana - initiating this dual-passenger mission that is to orbit a pair of telecommunications satellites: THOR 7 and SICRAL 2.
The payload lift performance for this first Ariane 5 mission of 2015 - which is designated VA222 in Arianespace's numbering system - is approximately 9,850 kg.
THOR 7 was built ...
After extraordinary science findings and technological innovations, a NASA spacecraft launched in 2004 to study Mercury will impact the planet's surface, most likely on April 30, after it runs out of propellant.
NASA's MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) spacecraft will impact the planet at more than 8,750 miles per hour (3.91 kilometers per second) on the side of the planet facing away from Earth. Due to the expected location, engineers will be unable to...
Astronomers have shown for the first time how star formation in "dead" galaxies sputtered out billions of years ago. ESO's Very Large Telescope and the NASA/ESA Hubble Space Telescope have revealed that three billion years after the Big Bang, these galaxies still made stars on their outskirts, but no longer in their interiors. The quenching of star formation seems to have started in the cores of the galaxies and then spread to the outer parts. The results will be published in the 17 April 2015 i...
The Atacama Large Millimeter/submillimeter Array (ALMA) has revealed an extremely powerful magnetic field, beyond anything previously detected in the core of a galaxy, very close to the event horizon of a supermassive black hole. This new observation helps astronomers to understand the structure and formation of these massive inhabitants of the centres of galaxies, and the twin high-speed jets of plasma they frequently eject from their poles. The results appear in the 17 April 2015 issue of the ...
Ceres' cratered north pole blazes through the darkness in new images captured by Dawn on April 10. The photos are the highest-resolution views of the world that Dawn has gotten since entering orbit on March 6, NASA officials said.
The cast and crew of "Episode VII: The Force Awakens" and the entire convention were thrown into a tizzy after the second teaser was revealed. Hear reactions from Mark Hamill, J.J. Abrams, Kathleen Kennedy and more.
After spending more than a month orbiting the dark side of the dwarf planet, NASA's probe finally captured some daylight gleaming off the north pole. This series of images were captured on April 10th, 2015 at a distance of 21,000 miles (33,000 km).
Italian astronaut Samantha Cristoforetti grappled Dragon with the space station's huge robotic arm at about 7:00 a.m. EDT (1100 GMT) Friday (April 17), securing the commercial capsule to the Earth-facing port of the Harmony module.
NASA's MESSENGER probe, which has been circling Mercury since March 2011, is nearly out of fuel and will say goodbye with a dramatic death plunge on April 30, provided one final orbit-raising maneuver scheduled for April 24 goes as planned.
They made the first 3D printer to be used in space possible. They made the files used to 3D print their tools in space available. Now, Made In Space is making the material used to 3D print in space for sale.
The largest ancient galaxies stopped forming stars in their cores about three billion years after the Big Bang, with this end of star birth spreading from the inside out in so-called 'dead' galaxies, scientists say.
