Chris Ashall, an assistant astronomer at the UH Mānoa Institute for Astronomy, was part of the global team that zeroed in on the stellar explosion known as SN 2024ggi. The supernova was first spotted ...

Using the Hubble Space Telescope and an array of other instruments, astronomers have probed supernova wreckage in the Large ...

A stronomers have been able to catch the earliest phases of supernova explosions with one of the most powerful observatories ...

While pottering around the universe, the Hubble Space Telescope recently clicked a photo of a dying star. The image sent back to Earth looks like a giant lidless eye peering back at the telescope, as ...

A magnetar known to scientists for 17 years might not have come from a supernova, like the rest of its ultra-magnetic brethren. But where did it form, then? The Hubble Space Telescope is on the case.

After three years of searching, scientists have caught the elusive phenomenon. — -- The "brilliant flash" that occurs when a star dies and explodes has been captured for the first time in visible ...
