- Astronomers have captured the first image of a binary star that lived through its companion going supernova. The surviving star — photographed by the Hubble Space Telescope — likely caused the explosion by stealing its partner's outer envelope, which helps wick away excess energy from the core. http://www.astronomy.com/news/2018/04/first-image-of-a-surviving-supernova-companion 6 comments science
- Einstein’s theory and ‘bent light’ reveal a way to weigh stars for first time. The scientists pointed the Hubble Space Telescope at a nearby binary star phenomenon called gravitational microlensing. That’s when gravity from a closer star slightly bends the light coming from a more distant star. http://www.pbs.org/newshour/rundown/einsteins-theory-bent-light-reveal-way-weigh-stars-first-time/ 21 comments science
