Moments ago, NASA announced that the Kepler space telescope, for the first time ever, has discovered a star that has a system of 8 planets, similar to our own solar system. The exceptional part of the discovery is that it was found in existing Kepler data, using google artificial intelligence software that was trained to find positive detections in over 30,000 data sets. Known as a neural network, the software was trained to look for patterns in the intensity of light from stars. Normally, humans would need to do this work, but with so much data, there simply wasn’t enough...
Every time we see amazing photos of galaxies or planetary disks, we can see most of the detail since we see them face on. But since the orientation of spiral galaxies in the universe is random, there are a plethora of galaxies ignored by image processors since we just can’t see much of the detail. We can still learn from edge-on spiral galaxies, just not as much as we can from those that are face on. We can see some fascinating dust lanes in the image above, and a ton of detail considering the view, but we don’t know what...
Move over Saturn, J1407b has rings that are far more spectacular than anyone would have imagined. This distant ‘planet’ (It may not actually be a planet) orbits an orange star 117 light-years away in the constellation Centaurus, and has a ring system consisting of 30 separate rings, each of which could be tens of Millions of Kilometres wide. In Spring of 2007, while monitoring the light from the star, astronomers noticed that the star was being eclipsed multiple times to varying degrees. This led the team, consisting of astronomers from Leiden Observatory and the University of Rochester, to conclude that...
