Like a witness to a violent death, NASA's Hubble Space Telescope recently gave astronomers an unprecedented, comprehensive view of the first moments of a star's cataclysmic demise. Hubble's data, combined with other observations of the doomed star from space- and ground-based telescopes, may give astronomers an early warning system for other stars on the verge of blowing up.

Tuesday, 26 October 2021 21:02
Astronomers searching for Earth-like planets in other solar systems have made a breakthrough by taking a closer look at the surface of stars.
A new technique developed by an international team of researchers—led by Yale astronomers Rachael Roettenbacher, Sam Cabot, and Debra Fischer—uses a combination of data from ground-based and orbiting telescopes to distinguish between light signals coming from stars and signals coming from planets orbiting those stars.
A study detailing the discovery has been accepted by The Astronomical Journal.
"Our techniques pull together three different types of contemporaneous observations to focus on understanding the star and what its surface looks like," said Roettenbacher, a 51 Pegasi b postdoctoral fellow at Yale and lead author of the paper.
