The Nancy Roman Telescope has reached another milestone in its development. NASA has announced that the space telescope’s primary mirror is now complete. The 2.4 meter (7.9 foot) mirror took less time to develop than other mirrors because it wasn’t built from scratch. It’s a re-shaped and re-surfaced mirror that came from the National Reconnaissance Office.

SpaceX says early tests of its rapidly growing fleet of internet-providing satellites are yielding promising results. Internal tests of a beta version of internet service from the company’s Starlink project show “super low latency and download speeds greater than 100” megabits per second, Kate Tice, a SpaceX senior certification engineer, said during a live broadcast

From 7 billion light-years away, a pair of colliding black holes has delivered up, on a shiny gravitational wave platter, one of the most sought-after detections in black hole astronomy – the extremely elusive ‘middleweight’ black hole, which lies in between stellar-mass black holes and supermassive behemoths. Not only, however, did the two colliding black

Galaxies are already pretty huge, billions to trillions of stars whirling around a supermassive black hole. But that’s not where their influence ends. A large, spherical halo of gas surrounds a galaxy, reaching vastly farther than the main population of stars, a bit like a galactic atmosphere. Hubble observations of our nearest galactic neighbour, Andromeda,

SpaceX is aiming to launch three rockets on Sunday, including two back-to-back Falcon 9 launches in Florida and a Starship test flight in Texas, if weather permits. The aerospace company said it intends to launch its twelfth Starlink mission at 10:12 am EST from the Kennedy Space Center in Florida, sending 60 Starlinks into orbit. The second

For as long as there has been a Universe, space has been expanding. It winked into existence roughly 13.8 billion years ago, and has been puffing up ever since, like a giant cosmic balloon. The current rate of this expansion is called the Hubble constant, or H0, and it’s one of the fundamental measurements of

Wormholes are a popular feature in science fiction, the means through which spacecraft can achieve faster-than-light (FTL) travel and instantaneously move from one point in spacetime to another. And while the General Theory of Relativity forbids the existence of “traversable wormholes”, recent research has shown that they are actually possible within the domain of quantum

A car-size asteroid flew within about 1,830 miles (2,950 kilometers) of Earth on Sunday. That’s a remarkably close shave – the closest ever recorded, in fact, according to asteroid trackers and a catalogue compiled by Sormano Astronomical Observatory in Italy. Because of its size, the space rock most likely wouldn’t have posed any danger to people on

Just as you thought it was safe to go back to ignoring Betelgeuse, the red giant star started acting up again. After its first round of dimming, and then brightening, Betelgeuse has now started to dim once again. Moreover, this new dimming is inconsistent with Betelgeuse’s current brightness variation cycle – so, once again, the
