Astronomers report the first ever measurement of light bending around a star other than our own.

Scientists have made a third detection of gravitational waves, again caused by the merger of two black holes. But they think there’s something different about the black holes in this case.

These ripples in the very fabric of the universe were hypothesized by Einstein a century ago. Now scientists have detected them for the third time in a year and a half – ushering in a new era in astrophysics.

It used to take weeks to find any of these mysterious signals from deep in space but when the new telescope started looking it found one within days. Then another.
When black holes collide, gravitational waves are created in space itself (image is a computer simulation).

Einstein called entanglement “spooky action at a distance”. But now it’s been used to design an incredibly sensitive detection method for gravitational waves.

People used to think that when they looked up at the night sky, they were seeing all of space. Then American astronomer Edwin Hubble found out something so amazing, NASA named a telescope after him.
Saturn and its rings backlit by the sun, which is blocked by the planet in this view. Encircling the planet and inner rings is the much more extended E-ring.

The recipe book for galaxy formation may need to be rewritten after the discovery of a massive galaxy that stopped making new stars early in the Universe’s history.

Many of the constellations we know in the night sky come from myths of the ancient Greeks. But similar stories are told by the oldest living cultures on Earth, including those of Australia.
