Speculative new research outlines a method for detecting extraterrestrial civilizations: by catching the gravitational waves produced by the collapse, or failure, of their warp drives. Sounds wild, but the concept is grounded in the principles of Einstein’s general relativity.
The cutting-edge Webb Space Telescope has spotted the most distant black hole merger yet, which occurred when the universe was just 740 million years old. It’s the first time astronomers have seen a merger so early in the universe’s history, making it a record breaker.
A leading gravitational wave observatory recently detected ripples in spacetime that scientists say came from the collision of a dead, superdense stellar remnant and an unknown object.
Stay calm, everybody stay calm. But it’s finally happening: The European Space Agency is committing itself to the Laser Interferometer Space Antenna (LISA), a gravitational wave observatory that will study some of the universe’s most enigmatic phenomena.
A team of scientists found a compact object 40,000 light-years from Earth that is either a very massive neutron star or an itsy-bitsy black hole, but they’re not sure which.
The Chandra X-ray Observatory didn’t exist in 1838, when the Eta Carinae star system started to brighten as it ejected material in an event named the “Great Eruption.” But traces of the eruption remain, and a timelapse has now been created by compiling 20 years of the space telescope’s data to sho
No space-based gravitational wave observatory exists…yet. But that hasn’t stopped a team of astronomers from demonstrating how the gravitational universe might look, using simulated data to create a “synthetic gravitational sky.”
