Gaia concludes Milky Way mapping efforts
Jan 15, 2025 (SPX)
Launched on 19 December 2013, Gaia's fuel tank is now approaching empty - it uses about a dozen grams of cold gas per day to keep it spinning with pinpoint prec...
Robotic SDSS telescopes revolutionize mapping the Milky Way
Jan 15, 2025 (SPX)
"Our observing robots have been working hard for a few years already. Now, they are helping us scan the sky in a whole new way," said Dhanesh Krishnarao, an Ass...
Hubble tracks down a 'blue lurker' among stars
Jan 14, 2025 (SPX)
Forensics with Hubble data show that the star has had a tumultuous life, mixing with two other stars gravitationally bound together in a remarkable triple-star ...
Webb observes expanding carbon-rich dust shells in star system
Jan 14, 2025 (SPX)
When the stars in Wolf-Rayet 140 approach one another in their elliptical orbit, their stellar winds collide, compressing material and forming carbon-rich dust....

MIT scientists pin down the origins of a fast radio burst
Jan 06, 2025 (SPX)
Since the first fast radio burst (FRB) was discovered in 2007, astronomers have detected thousands of FRBs, whose locations range from within our own galaxy to ...
Carbon's cosmic 'conveyer belt' across time and space
Jan 06, 2025 (SPX)
A team of scientists based in the U.S. and Canada recently confirmed that carbon and other star-formed atoms don't just drift idly through space until they are ...
Researchers identify neutron stars as sources of fast radio bursts
Jan 06, 2025 (SPX)
