When massive stars detonate as supernovae, they leave often behind a pulsar. These fast rotating stellar corpses have fascinated scientists since their discovery in 1967. One nearby pulsar turns 174 times a second and now, its size has been precisely measured. An instrument on board the International Space Station was used to measure x-ray pulses from the star. A supercomputer was then used to analyse its properties and found it was 1.4 times the mass of the Sun and measured only 11.4 km across!

Solar Flares and Solar Magnetic Reconnection Get New Spotlight in Two Blazing Studies
Two recent studies published in The Astrophysical Journal discuss findings regarding solar flare properties and a new classification index and the Sun’s magnetic field, specifically what’s called solar magnetic reconnection. These studies hold the potential to help researchers better understand the internal processes of the Sun, specifically pertaining to solar flare activity and space weather. Here, Universe Today discusses these two studies with both lead authors regarding the motivation behind the studies, significant results, and implications on our understanding regarding solar flares and space weather.

Ariane 6: Thank you Space Team Europe
Video: 00:02:27
The first launch of Ariane 6 is a collective success for all of Europe. First flights are no easy thing, but Europe now has a heavy-lift rocket able to launch any mission into any orbit. From Earth observation satellites that monitor our changing climate, predict the weather and assist emergency responders during disasters; to communication and navigation systems that keep Europeans in touch and in the right place; to deep space telescopes and explorers expanding our understanding of the Universe and our place within it – Ariane 6 has restored Europe’s autonomous access to space.
