In one of the most surprising recent science stories, some astronomers have announced that they may have found some evidence for an unknown large planet (possibly much larger than Earth) far beyond the orbit of Pluto. They studied the orbits of a number of objects in the solar system and found some unusual features that might be explained by a new planet. Of course, there’s still a chance that this is just a coincidence and nothing too strange is going on, but it’s an interesting hypothesis. In fact, such studies have been used in the past to predict new celestial objects, so this isn’t unprecedented. I’ve been told that the scientists involved are generally very serious people and so this does not seem to be a hoax and the work involved shouldn’t have any serious mistakes. But, we can’t start saying that there is definitely a new planet until we actually find it. Given the huge distances involved, it might take quite a while to find the planet if it really exists.
The press is talking about that star that shows some odd features again and once again people are speculating that maybe it’s behavior is caused by aliens. Once again, there is basically zero chance that we’ve found evidence of something like a Dyson sphere. There is almost certainly some mundane explanation even if it’s something we haven’t really thought of or seen before.
It was announced earlier today that David Bowie has died of cancer. His condition was kept out of the media, so this has been quite a surprise to many people. He just released a new album on Friday.
