- Astronomers have observed the flattest explosion ever seen in space. The explosion, which was 180 million light years away, challenges current human understanding of explosions in space: they appear much flatter than previously thought possible. https://academic.oup.com/mnras/advance-article/doi/10.1093/mnras/stad539/7049972 21 comments science
- Stars with less than half the mass of our Sun are able to host giant Jupiter-style planets, in conflict with the most widely accepted theory of how such planets form, according to a new study https://academic.oup.com/mnras/advance-article/doi/10.1093/mnras/stad626/7069338 3 comments science
- Einstein’s theory helps to reveal Jupiter’s distant duplicate. A near-identical twin of Jupiter discovered around a distant star is the first planet to be found from space using a gravitational effect called microlensing. https://academic.oup.com/mnras/advance-article-abstract/doi/10.1093/mnras/stad212/7008855?login=false&redirectedFrom=fulltext 13 comments science

- The ultimate fate of a star shredded by a black hole: Much of the star’s mass ended up in symmetrical cloud that hid black hole. This tidal disruption of a sun-like star by a black hole 1 million times more massive than itself took place 215 million light years from Earth. https://academic.oup.com/mnras/advance-article/doi/10.1093/mnras/stac1727/6617652 4 comments science
