Scientists have noticed two space rocks which may be Earth’s freshest asteroid neighbors. The unusual pair of near-Earth asteroids is separated by about 600,000 miles (1 million kilometers), and researchers calculated that they likely broke off the identical asteroid just just a few centuries ago. “It’s very exciting to find such a young asteroid pair …

As Comet Leonard bid farewell to Earth and flew previous Venus, a sun-studying spacecraft flew through the comet’s lengthy tail, giving people a brand new perspective on the icy wanderer. Discovered final January and also referred to as Comet C/2021 A1, Comet Leonard was maybe the most spectacular customer for skywatchers in 2021. The object …

One of the most important cosmological mysteries is why the universe is made up of way extra matter than antimatter, basically why we exist. Now, a workforce of theoretical physicists says they know learn how to discover the reply. All they should do is detect the gravitational waves produced by weird quantum objects referred to as …

General relativity has withstood maybe its toughest problem so far. The theory, which Albert Einstein printed in 1916, revolutionized our understanding of physics and the cosmos. It explains gravity as a consequence of space-time’s flexibility: Massive objects warp space-time, creating depressions round which different our bodies orbit. Scientists have put general relativity to the take …
