Saio et al. created a model that simulated Betelgeuse’s pulsations and say it provides unique insight into the star’s internal status. The only way for Betelgeuse to pulsate in this way is if it is at the very end of its carbon burning period. That means the collapse of this star’s core and the accompanying supernova is imminent. “After carbon is exhausted in the core, a core-collapse leading to a supernova explosion is expected in a few tens of years,” they conclude.

Phosphorus, a key chemical element for many biological processes, has been found for the first time in an ocean beyond Earth.

The Euclid telescope, expected to launch next month, will be able to observe galaxies out to 10 billion light-years. Can anyone find a map of the local universe to that scale? I'd like to see where structures like the Hercules–Corona Borealis Great Wall and the Laniakea Supercluster are relative to each other.
