A team of researchers, including those from the University of Tokyo, spotted a rare kind of planet that's unusually hot and eccentric. TOI-1355 b orbits its star, TOI-1355, which is also much hotter than our sun, in a strange way and incredibly quickly, completing an orbit in about two Earth days. The work is published in the journal Publications of the Astronomical Society of Japan.

A new way to accurately measure the distance between quasar pairs—the blazing, black-hole-powered centers of distant galaxies that appear side by side in space—is showing promise through University of Alberta research.

If some aspects of cosmic topology turn out to be true, the idea that starships might voyage across the cosmos for hundreds of thousands of light-years without ever returning to the same neck of spacetime could be problematic.

Gli astronomi hanno scoperto 84 misteriose sorgenti di raggi X in sei galassie vicine. Chiamate “hypersoft X-ray sources”, potrebbero essere sistemi binari contenenti nane bianche, stelle di neutroni o buchi neri e aiutare a risolvere due importanti enigmi dell'astrofisica.
