New Scientist 4 Oct 2019, 11:26 UTC Strange blasts of radiation from space called fast radio bursts (FRBs) have been puzzling astronomers for years, as we don’t know what causes them. Now, we have a fresh clue as to how some of the weirdest kind of FRBs may form. Some of these bursts repeat over a period of years, and it appears they could be caused by starquakes in the aftermath of a collision of two stars.
Astro Watch 4 Oct 2019, 07:43 UTC There is an as-yet-unseen population of Jupiter-like planets orbiting nearby Sun-like stars, awaiting discovery by future missions like NASA’s WFIRST space telescope, according to new models of gas giant planet formation by Carnegie’s Alan Boss described in an upcoming publication in The Astrophysical Journal. His models are supported by a new Science paper on the surprising discovery of a gas giant planet orbiting a low-mass star.
New Scientist 4 Oct 2019, 07:41 UTC A vast spider’s web of matter is thought to stretch across the whole universe and astronomers have just got the best view of it yet. Hideki Umehata at the RIKEN institute in Japan and his colleagues used the Very Large Telescope (VLT) in Chile to observe a young cluster of galaxies 12 billion light years from Earth, called SSA22. Peering into the cluster, they spotted wispy filaments of hydrogen gas spanning the space between the galaxies. These seem to be filaments of the long-theorised cosmic web.
Universe Today 4 Oct 2019, 07:40 UTC The mole is the name given to the Heat Flow and Physical Properties Package (HP3) instrument on NASA’s Mars InSight lander. It’s job is to penetrate into the Martian surface to a depth of 5 meters (16 ft) to measure how heat flows from the planet’s interior to the surface. It’s part of InSight’s mission to understand the interior structure of Mars, and how it formed.
