Hubble sees unexplained brightness from colossal explosion
Long ago and far across the universe, an enormous burst of gamma rays unleashed more energy in a half-second than the Sun will produce over its entire 10-billion-year lifetime. Astronomers were baffled that the near-infrared emission was 10 times brighter than predicted.

Playing detective on a galactic scale: huge new dataset will solve multiple Milky Way mysteries
How do stars destroy lithium? Was a drastic change in the shape of the Milky Way caused by the sudden arrival of millions of stellar stowaways? These are just a couple of the astronomical questions likely to be answered with the largest set of stellar chemical data ever compiled.

Source of mysterious radio waves from space pinpointed
Three independent studies have found the source of a particular fast radio burst (FRB) - unexplained radio waves that reach us from space and last just a fraction of a second - helping to solve the mystery of what causes the strange phenomenon.

Galaxies have gotten hotter as they've gotten older
The universe is some 13 billion years old and is often imagined as just a vast expanse of dark, almost empty space getting colder with time. Yet new research shows that all of its clusters of galaxies are simultaneously getting hotter as they get older.

The farthest black hole from a rare family of galaxies
An international team of astronomers has identified the farthest example of a rare class of gamma-ray emitting galaxies. The so-called BL Lacertae object was discovered at cosmic dawn, within the first two billion years of the age of the universe.
