Astrophiz Podcast 30 is Out
Elizabeth is a British astrophysicist who works at JAXA, the Institute of Space and Astronomical Science, the Japan Aerospace Exploration Agency.
I tell you what to look for in the night and morning skies over the next few weeks.
In the news:
1. The Explosive beginnings of a supernova spotted for the first time (via Amy Middleton reporting for cosmosmagazine) and she writes about a new paper in Nature Physics about the spectacular transformation of a star, assumed to have been a red supergiant, into a supernova, just three hours after it began.
2. The unexpected discovery of young stars in old star clusters may send scientists back to the drawing board and change our understanding of how stars evolve (via Monthly Notices of the Royal Astronomical Society: Letters, posted in phys.org/astronomy)
3. A White Dwarf star X9, is the closest star ever found orbiting a black hole, and it’s orbiting at an astonishing 12 million km/h. The stellar dance between these two objects is taking place inside a globular cluster 47 Tucanae, a group of about a million stars orbiting the galactic centre about 15,000 light years from Earth. (reported by Marcus Strom for the Sydney Morning Herald)
