James Webb Space Telescope spots neutron star hiding in supernova wreckage

Using the James Webb Space Telescope (JWST), astronomers have ended a nearly decade-long game of celestial hide-and-seek after they discovered a neutron star in the wreckage of a stellar explosion. Supernova 1987A represents the remains of an exploded star that once had a mass around 8 to 10 times that of the sun. It is … Read more

Scientists create 5 new isotopes to learn how neutron star collisions forge gold

Researchers have synthesized five new isotopes that could help bring the stars down to Earth — and coax scientists a step closer to understanding how collisions between ultra-dense, dead stars could create heavy elements like gold and silver.  The isotopes are Thulium-182, thulium-183, ytterbium-186, ytterbium-187 and lutetium-190; this is the first time they’ve been ever … Read more

3D-Printed Cosmic Clouds Unravel the Mysteries of Star Formation

Now I’m a professional stargazer, and things haven’t changed much. These days I search for patterns in molecular clouds, the birthplaces of … Read more

Former Disney TV star Bridgit Mendler co-founds satellite ‘data highway’ startup

On Tuesday (Feb. 20), after a relatively long hiatus from the public eye, Bridgit Mendler announced the launch of her new satellite data startup, Northwood. Beyond introducing quite an interesting company — one that aims to make satellite technology more accessible by mass-producing data-retrieving ground stations on Earth — there’s another major reason the launch … Read more

For this dead star, 72 Earth years is a single day

Astronomers have discovered an extraordinary binary system in which a “dead star,” or white dwarf, whips around its blisteringly hot and tiny stellar companion so fast that it squeezes almost 72 Earth years into just one Earth day. The system, designated TMTS J0526, was spotted by a Tsinghua University team using the  Tsinghua University-Ma Huateng Telescope for … Read more
