His reasoning: When a train starts running from one station to the next station, conceptually, these two stations will temporarily be closer to each other. And that is exactly what this visualization shows: whenever a train moves to the next station — and only for as long as a train is moving — the origin station...
Jan Willem Tulp, in collaboration with the European Space Agency, produced the ESA Star Mapper. It shows nearly 60,000 stars in a combination of different scales and projections. Be sure to switch to “explore” mode and click on the play button to see a prediction for how the stars will move over many years. [Thanks, Jan] Tags: Jan Willem Tulp, space

Astrobiology uses the Goldilocks principle in the argument that a planet must neither be too far away from, nor too close to a star to support life; either extreme would result in a planet incapable of supporting life. Such a planet is colloquially called a...
