After NASA‘s Cassini spacecraft discovered a surprisingly large amount of methane — along with a relative high concentration of dihydrogen and carbon dioxide molecules — in the plumes of Saturn’s moon, Enceladus, a study published in Nature Astronomy concludes that the high levels of gas cannot be explained by known geochemical processes.
A huge piece of space junk is about to make an uncontrolled re-entry back into Earth’s atmosphere, threatening to drop debris on a number of cities around the world in the coming days. It’s leftover from China’s first module for its new Tianhe space station — and no one knows where it will land.
Some 230 million light-years from Earth, there’s a black hole going places. These extraordinarily dense objects are usually found sitting at the center of a galaxy violently gobbling up matter, so it was a surprise when astronomers spotted this one moving out of step with its resident galaxy.
Who says you can’t lose your atmosphere to a nearby red dwarf and then grow a new one with the help of volcanic activity? This resilient planet, located 41 light-years from Earth, appears to be thriving again after a rough encounter with its host star.
Einstein’s theory of general relativity puts a speed limit on all matter in the universe, creating a barrier preventing acceleration from below to above the speed of light.
However, an independent group of scientists, inventors, and engineers called Applied Physics recently proposed the first model for a physical warp drive, according to a recent study published in the peer-reviewed journal Classical and Quantum Gravity.
The most distant Solar System object, Farout, has lost its crown after just two years. As Inverse reports, astronomers have confirmed that the planetoid Farfarout is now the farthest known Solar System object. It’s currently 132AU, or about 12.3 billion miles from the Sun (Farout is ‘just’ 120AU away), and its elongated orbit will take it 175AU away. For context, Pluto is 34AU from our host star — Farfarout reaches over five times that distance, and takes about 1,000 years to complete an orbit.
