New Scientist 18 May 2021, 18:55 UTC Astronomers have found a mysterious circle of radio waves, the fifth Odd Radio Circle (ORC) ever detected, but its cause is still unclear. It could be simply the side view of a galaxy with an active black hole at its centre, or possibly the result of a supermassive black hole merger.
Centauri Dreams 18 May 2021, 09:49 UTC While a planet’s position in the habitable zone is thought critical for the development of life like ourselves, new work out of Rice University suggests an equally significant factor in planetary growth. Working at a high-pressure laboratory at the university, Damanveer Grewal and Rajdeep Dasgupta have explored how planets capture and retain key volatiles like nitrogen, carbon and water as they form The team used nitrogen as a proxy for volatile distribution in a range of simulated protoplanets.
Sky and Telescope 17 May 2021, 16:37 UTC The Zhurong rover has successfully landed on the Red Planet in an ambitious first for China’s space agency.
Universe Today 17 May 2021, 11:41 UTC Meteors hit much harder on Mars than they do on the Earth. Lack of atmosphere obviously contributes to that, but its proximity to the asteroid belt also makes the red planet a more likely target for some gravitationally disturbed rock to run into. Now that we have a satellite infrastructure consistently monitoring Mars, we are able to capture the aftermath of what happens when it is pummeled by space debris, and the results can be dramatic.
SciTech Daily 17 May 2021, 02:39 UTC A research study using data from NASA’s Chandra X-ray Observatory and Hubble Space Telescope gives new insight into an important question: how habitable are planets that orbit the most common type of stars in the Galaxy?
Universe Today 14 May 2021, 17:03 UTC A new report from the US Government Accountability Office (GAO) says that the launch of the long-awaited, highly anticipated James Webb Space Telescope (JWST) will very likely be delayed due to an anomaly identified in the Ariane 5 launch vehicle. Launch for JWST is currently scheduled for October 31, 2021, but that date could slip by at least a couple of weeks.
Centauri Dreams 14 May 2021, 10:32 UTC Is there any chance we may one day find technosignatures around the nearest stars? If we were to detect such, on a planet, say, orbiting Alpha Centauri B, that would seem to indicate that civilizations are to be found around a high percentage of G- and K-class stars. Brian Lacki (UC-Berkeley) examined the question from all angles at the recent Breakthrough Discuss, raising some interesting issues about the implications of technosignatures, and the assumptions we bring to the search for them.
Parabolic Arc 14 May 2021, 03:07 UTC By January, we can expect to see paying customers on three American and Russian flights to the International Space Station (ISS), one Crew Dragon mission in Earth orbit, and two or more suborbital flights.
