The Space Reporter 22 Mar 2017, 14:19 UTC Mars’ two small moons Phobos and Deimos may have originated as rings around the planet rather than as captured objects from the asteroid belt between Mars and Jupiter, according to a new study published in the journal Nature Geoscience.
The Space Reporter 22 Mar 2017, 14:03 UTC A volcano on Mars called Arsia Mons apparently went dormant right around the time that dinosaurs were becoming extinct. According to Space.com, a new computer model has determined that the approximate time of Arisia Mons’ last eruption was about 50 million years ago. This was about the same time as Earth’s Cretaceous-Paleogene extinction event, which served as the death knell of the dinosaurs. “We estimate that the peak activity for the volcanic field at the summit of Arsia Mons probably occurred approximately 150 million years ago — the late Jurassic period on Earth — and then died out around the same time as Earth’s dinosaurs,” Jacob Richardson of NASA said in a statement. “It’s possible, though, that the last volcanic vent or two might have been active in the past 50 million years, which is very recent in geological terms.” Arsia Mons is one of three huge volcanoes that make up the mountain group known as Tharsis Montes. The three ancient volcanoes lie in a line in Mars’ Tharsis plateau, and Arsia Mons is the southernmost. The trio is located close to Olympus Mons, the largest volcano in the solar system. The caldera that tops Arsia Mons is 69 miles ...
All About Space 22 Mar 2017, 13:15 UTC A routine check of the aluminium wheels on NASA’s Curiosity Mars rover has found two small breaks on the rover’s left middle wheel-the latest sign of wear and tear as the rover continues its journey, now approaching the 16-kilometre (10-mile mark).
Scientific American 22 Mar 2017, 11:15 UTC Sometime in the early 2030s, NASA hopes to attempt a landing on Jupiter’s moon Europa. A four-legged spacecraft would descend towards the icy surface, ready to hunt for signs of alien life in a buried ocean.
SPACE.com 22 Mar 2017, 11:00 UTC Mars' intriguing dark streaks may not be evidence of liquid water after all. These long and narrow features, known as recurring slope lineae (RSL), darken some slopes near the Martian equator for weeks at a time during the warmest parts of the year. They were discovered in 2011, by scientists studying images captured by NASA's Mars Reconnaissance Orbiter (MRO).
EarthSky Blog 22 Mar 2017, 10:01 UTC NASA said on March 20, 2017 that scientists used data from its Swift satellite to get a comprehensive look at a star’s death spiral into a black hole. The star was much like our sun. The black hole contains some 3 million times the mass of our sun and lies at the center of a galaxy 290 million light-years away. As the black hole tore the star apart, it produced what scientists call a tidal disruption event. They’ve labeled this particular event – an eruption of optical, ultraviolet, and X-ray light, which began reaching Earth in 2014 – as ASASSN-14li. The scientists have now used Swift’s data to map out how and where these different wavelengths were produced, as the shattered star’s debris circled the black hole. The video animation above is an artist’s depiction of what these scientists believe happened. They said it took awhile for debris from the star to be swallowed up by the black hole. Dheeraj Pasham, an astrophysicist at the Massachusetts Institute of Technology (MIT) in Cambridge, Massachusetts, and the lead researcher of the study, said: We discovered brightness changes in X-rays that occurred about a month after similar changes were observed in visible and ...
The Daily Galaxy 22 Mar 2017, 02:57 UTC The silence of an immense desolate land in which to search for reverberations coming from the time at which everything began. The Simons Observatory will be built in the Chilean Atacama desert at an altitude of several thousand meters for the purposes of studying primordial gravitational waves which originated in the first instants of the Big Bang.
Universe Today 21 Mar 2017, 19:38 UTC Since it began its second operational run in 2015, the Large Hadron Collider has been doing some pretty interesting things. For example, starting in 2016, researchers at CERN began using the collide to conduct the Large Hadron Collider beauty experiment (LHCb). This investigation seeks to determine what it is that took place after the Big Bang so that matter was able to survive and create the Universe that we know today. In the past few months, the experiment has yielded some impressive results, such as the measurement of a very rare form of particle decay and evidence of a new manifestation of matter-antimatter asymmetry. And most recently, the researchers behind LHCb have announced the discovery of a new system of five particles, all of which were observed in a single analysis.
Lights in the Dark 21 Mar 2017, 17:24 UTC From July 1969 to December 1972, 12 American astronauts landed in six different locations on the lunar surface as part of NASA’s Apollo program, leaving their footprints and taking samples and data that are still being used today to learn about the Moon. The Apollo landing sites remain exactly as they were left over four decades ago—footprints, rover tracks, discarded equipment and all—and with a new generation of space explorers around the world setting their sights on the Moon it’s important that we make sure these six off-world locations are preserved, just as would be done with any historic artifact.
