Birth of a black hole or neutron star captured for first time

After combining several imaging sources, including hard X-rays and radiowaves, a team now speculates that the telescopes captured the exact moment a star collapsed to form a compact object, such as a black hole or neutron star. The stellar debris, approaching and swirling around the object's event horizon, caused The Cow's remarkably bright glow.

Astronomers find signatures of a 'messy' star that made its companion go supernova

Astronomers announced that they have identified the type of companion star that made its partner in a binary system, a carbon-oxygen white dwarf star, explode. Through repeated observations of SN 2015cp, a supernova 545 million light years away, the team detected hydrogen-rich debris that the companion star had shed prior to the explosion.

Giant pattern discovered in the clouds of planet Venus

Astronomers have identified a giant streak structure among the clouds covering planet Venus based on observation from the spacecraft Akatsuki. The team also revealed the origins of this structure using large-scale climate simulations.

Cosmic telescope zooms in on the beginning of time

Observations from Gemini Observatory identify a key fingerprint of an extremely distant quasar, allowing astronomers to sample light emitted from the dawn of time. Astronomers happened upon this deep glimpse into space and time thanks to a foreground galaxy acting as a gravitational lens, which magnified the ancient light. The Gemini observations provide critical pieces of the puzzle in confirming this object as the brightest appearing quasar so early in the history of the universe.
