In another big science news story from the past few days, astronomers have found evidence of a supermassive black hole that appears to be much larger than is expected from theoretical models. The black hole in question lies at the center of a distant galaxy and is also quite old (9 billion years). There is a related arXiv paper here. This is well outside my field of expertise, but it looks like the idea is that this might be the first discovered in a new class of this sort of galaxy.
NASA announced a couple days ago that they will be holding a press conference for a big announcement about Mars. The announcement is later today. Various people are speculating about what the announcement might be, with many suggesting that it probably has something to do with evidence for water on Mars. The press release has minimal information, so we’ll just have to wait and see what this is about.
