Work by Cardiff University astronomers suggests there may be a cosmic lack of a chemical element essential to life. Dr. Jane Greaves and Dr. Phil Cigan will present their results at the European Week of Astronomy and Space Science in Liverpool.

A Purdue University-affiliated startup is seeking to open up access to space for microsatellite companies by modernizing a launch technique first used in the 1950s.
Astronomers using NASA’s Hubble Space Telescope have for the first time precisely measured the distance to one of the oldest objects in the universe, a collection of stars born shortly after the big bang.
A Columbia University-led team of astrophysicists has discovered a dozen black holes gathered around Sagittarius A* (Sgr A*), the supermassive black hole in the center of the Milky Way Galaxy. The finding is the first to support a decades-old prediction, opening up myriad opportunities to better understand the universe.
Chemical models developed to help limit the emission of pollutants by car engines are being used to study the atmospheres of hot exoplanets orbiting close to their stars. The results of a collaboration between French astronomers and applied combustion experts will be presented by Dr Oliva Venot and Dr Eric Hébrard at the European Week of Astronomy and Space Science (EWASS) 2018 in Liverpool.
In a new study published today in the Astrophysical Journal, researchers from New York University Abu Dhabi and NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, CA, share new findings about how the presence of “giant” planets (between 10 and 1000 times as large as the Earth) affects potentially habitable neighbors that would be discovered with the next generation of ground-based and space-borne telescopes.
When NASA astronaut Kjell Lindgren blasted off from Kazakhstan in July of 2015 for his first expedition aboard the International Space Station, he had some lofty expectations:
This past weekend, a lot of attention was focused on the Tiangong-1 space station. For some time, space agencies and satellite trackers from around the world had been predicting when this station would fall to Earth. And now that it has safely landed in the Pacific Ocean, many people are breathing a sigh of relief. While there was very little chance that any debris would fall to Earth, the mere possibility that some might caused its share of anxiety.
Using microlensing method, an international team of astronomers has detected a new “super-Earth” alien world circling a low-mass star about five times less massive than our sun. The finding is detailed in a paper published March 28 on the arXiv pre-print repository.
“Three-dimensional Features of the Outer Heliosphere Due to Coupling between the Interstellar and Heliospheric Magnetic Field. V. The Bow Wave, Heliospheric Boundary Layer, Instabilities, and Magnetic Reconnection” originally appeared this past August in the Astrophysical Journal, a publication of the American Astronomical Society. But the paper, whose co-authors include two researchers at The University of Alabama in Huntsville (UAH), has recently received renewed attention thanks to its unique insights into physical phenomena occurring at the heliospheric interface.
