Using data from the Dark Energy Survey, researchers have found and cataloged more than 300 minor planets beyond Neptune, including more than 100 new discoveries. This updated catalog of trans-Neptunian objects, and the methods used to find them, could aid in future searches for undiscovered planets in the far reaches of the solar system.
Astronomers detected a giant planet orbiting a small star. The planet has much more mass than theoretical models predict.
Researchers have identified a young star with four Jupiter and Saturn-sized planets in the most extreme range of orbits yet observed around it, the first time that so many massive planets have been detected in such a young system — raising interesting questions about how such a system might have formed.
Earth and Mars will be closer together in distance than they have for 15 years, making the Red Planet easily visible with the naked eye.
A day was once only 18 hours long when the moon was closer to Earth, a new study has claimed.
