It was announced a few days ago that the Hubble Space Telescope has found the most distant galaxy yet discovered. The light from that galaxy (GN-z11)was emitted over 13 billion years ago, close to the beginning of the universe.
In honor of the 25th anniversary of the launching of the Hubble space telescope, which will be later this year, a team of astronomers have released an updated version of one of the most famous Hubble images – the feature known as the “Pillars of Creation.”
This is both a really beautiful image and also a useful image for science. The new image covers a much larger region in the sky and also includes measurements at infrared wavelengths. It has a lot more detail and also shows the same feature 20 years after the original. The astronomers have noticed some important differences between the images that give hints about what is going on in these gas clouds. The most important difference mentioned in many of the articles is what looks like a jet that was emitted from a newly-formed or forming star.
