The UK under a curtain of aurora

The NICER telescope array aboard the International Space Station has made the most accurate measurements yet of a pulsar’s mass and size.

Astronomers are using the NASA/ESA Hubble Space Telescope to study aurorae — stunning light shows in a planet’s atmosphere — on the poles of the largest planet in the solar system, Jupiter. This observation program is supported by measurements made by NASA’s Juno spacecraft, shortly to arrive at the gas giant.
