Twin lunar-orbiting NASA spacecraft that have allowed scientists to learn more about the internal structure and composition of the moon are being prepared for their controlled descent and impact on a mountain near the moon's north pole at about 5:28 p.m. EST Monday, Dec. 17.
Scientists have used powerful X-rays from the Linac Coherent Light Source (LCLS) at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory, to study and measure, in atomic detail, a key process at work in extreme plasmas like those found in stars, the rims of black holes and other massive cosmic phenomena.
The discovery of a bingeing black hole that is expelling powerful beams of material has shed new light on some of the brightest X-ray sources seen in other galaxies, according to new research led by Durham University.
A new data analysis tool will be used by researchers of the ARC Centre of Excellence for All-sky Astrophysics (CAASTRO) at Curtin University to handle large quantities of data coming in from the new low frequency radio telescope, the Murchison Widefield Array (MWA).
On the evening of 13 and the morning of 14 December, skywatchers across the world will be looking up as the Geminid meteor shower reaches its peak, in potentially one of the best night sky events of the year.
An asteroid that some day might threaten Earth is passing relatively close by on the night of December 11-12, and its gliding path among the stars will be tracked by a team of high-school students at the Clay Center Observatory in Brookline, Massachusetts.
In December, a NASA mission to study the sun will make its third launch into space for a six-minute flight to gather information about the way material roils through the sun's atmosphere, sometimes causing eruptions and ejections that travel as far as Earth.
Black holes are surrounded by many mysteries, but now researchers from the Niels Bohr Institute, among others, have come up with new groundbreaking theories that can explain several of their properties. The research shows that black holes have properties that resemble the dynamics of both solids and liquids.
Typically satellites launch from Earth, requiring dedicated launch vehicles to propel them into the proper orbit. The cost for this launch scenario could be reduced considerably if there was another way to get the satellites into their optimal orbit. The Japan Aerospace and Exploration Agency (JAXA) found a way to cut the costs of this activity by designing a small satellite launcher, installed recently on the International Space Station.
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.
