Spectacular ultraviolet storms in big planet’s aurora, generated by charged particles from its volcanic moon, Io. The midnight births of the dramatic bright surges in Jupiter’s aurora known as dawn storms are captured in a new study of data from the Juno space probe.

The storms, which consist of brightenings and broadenings of the dawn flank of an oval of auroral activity that encircles Jupiter’s poles, evolve in a pattern surprisingly reminiscent of familiar surges in the aurora that undulate across Earth’s po...

A new study suggests that hot, rocky exoplanets could not only develop atmospheres full of water vapor, but keep them for long stretches. An atmosphere is what makes life on Earth’s surface possible, regulating our climate and sheltering us from damaging cosmic rays. But although telescopes have counted a growing number of rocky planets, scientists had thought most of their atmospheres long lost.

However, a new study by University of Chicago and Stanford University researchers expands our p...

In the first all-sky survey by the eROSITA X-ray telescope onboard SRG, astronomers at the Max Planck Institute for Extraterrestrial Physics have identified a previously unknown supernova remnant, dubbed “Hoinga.” The finding was confirmed in archival radio data and marks the first discovery of a joint Australian-eROSITA partnership established to explore our Galaxy using multiple wavelengths, from low-frequency radio waves to energetic X-rays. The Hoinga supernova remnant is very large and located far from the galactic plane — a surprising first finding — implying that the next years might bring many more discoveries.

Massive stars end their lives in gigantic supernova explosions when the fusion processes in their interiors no longer produce enough energy to counter their gravitat...

Astronomers have painted their best picture yet of an RV Tauri variable, a rare type of stellar binary where two stars — one approaching the end of its life ...
