To find giant black holes, start with our solar system’s center

A new study from researchers at Vanderbilt University suggests that to find the most massive black holes, measure the effects of their gravitational waves on the flashes of light coming from pulsars. The best location to do that is at the precise gravitational center of the solar system. Source: https://earthsky.org/space/black-holes-gravitational-waves-pulsars-solar-system…

Observatory’s quick reflexes capture fleeting flash

Rapid follow-up of the optical afterglow from one of the most distant confirmed short gamma-ray bursts (SGRB), thought to be the merger of two neutron stars, is casting new light on these enigmatic objects. The observations, made by the international Gemini Observatory, a Program of NSF’s NOIRLab, confirmed the object’s distance and placed it squarely in the epoch of cosmic high…

Breakthrough in deciphering birth of supermassive black holes

A research team led by Cardiff University scientists say they are closer to understanding how a supermassive black hole (SMBH) is born thanks to a new technique that has enabled them to zoom in on one of these enigmatic cosmic objects in unprecedented detail.

A proposed new mission to Venus

The proposed VERITAS mission to Venus is one of the finalists for NASA’s Discovery Program. If selected, it will revolutionize our knowledge about the planet’s geology and how this formerly habitable world became a fiery wasteland.

Alien civilisations could move their star to avoid a cosmic disaster

A researcher has come up with an idea for a huge machine that advanced civilisations could use to move their star system around the galaxy – and we might be able to spot one in action Source: https://www.newscientist.com/article/2248537-alien-civilisations-could-move-their-star-to-avoid-a-cosmic-disaster/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
