By Mike Wehner From BGR Like many of the larger bodies in our solar system, Saturn’s massive moon Titan has long been of interest to astronomers due to its unique surface features. NASA’s Cassini spacecraft, which studied Saturn for over 13 years, spent a great deal of time examining Titan as well, and data it […]

Hundreds of thousands of asteroids in our Solar System were born from a few now-dead planetsbean Court of Justice

By Mike Wehner From BGR It’s tempting to imagine that the asteroids that litter our Solar System have been there from the start, circling the Sun for ages while the planets formed, but new research suggests that things simply didn’t play out that way. They weren’t just transient collections of dusty and debris that happened […]

From hindustan times A huge black hole — about 100,000 times more massive than our Sun — has been discovered lurking in a toxic gas cloud near the heart of the Milky Way. If confirmed, the object will rank as the second largest black hole in the Milky Way after the supermassive Sagittarius A* which […]

Supermassive black hole set a record for longest lunch ever

By Rob LeFebvre From engadget The feeding frenzy enriches our understanding of the universe. When a black hole eats a nearby star, the resulting X-rays typically fade within a year or so. That’s why astronomers are excited about a giant black hole that’s been shedding telltale radiation for close to 10 years. Dubbed XJ1500+0154, this […]

It rains rubies and sapphires on this distant Jupiter-like planet

Pin It

By George Dvorsky From Gizmodo A Jupiter-like planet located 1,000 light-years from Earth is exhibiting some rather strange meteorological behaviour. The clouds on this planet appear to be made from corundum — the same mineral that produces rubies and sapphires. Using the Kepler space telescope, astronomers from Warwick University have detected individual weather patterns on […]
