Studies published thus far have provided sufficient arguments that life as we know it would have the highest chances of emerging on planets located in their star's habitable zones. These are areas around each star where temperatures are right to support liquid water. A new study now shows that chemistry also pla... |

VFTS 102 is the fastest-rotating star ever discovered, no doubt about it. At an average speed of 1 million miles (1.61 million kilometers) per hour, it spins about 100 times faster than our own star.
The object was recently identified in the Large Magellanic Cloud, a dwarf galaxy that orbits the Milky Way in close ... |
