Black Hole

Years before she was even sure the James Webb Space Telescope would successfully launch, Christina Eilers started planning a conference for astronomers specializing in the early universe. She knew that if — preferably, when — JWST started making observations, she and her colleagues would have a lot to talk about.…

News Science & Astronomy White holes are theoretical cosmic regions that function in an opposite way to black holes. (Image credit: Future/Adam Smith) Black holes seem to get all the attention. But what about their mirror twins, white holes? Do they exist? And, if so, where are they?  To understand…

Astronomers transfixed the public in April 2019 when they released the first-ever image of a black hole, produced by radio wave data from a collaboration of telescopes around the world known collectively as the Event Horizon Telescope. Now, a team of physicists and researchers have developed the plans for the…

Space Exotic stars may be scattered throughout the cosmos, from boson stars that could look like black holes to dark stars that might be powered by dark matter By Leah Crane Stars can theoretically come in many exotic types Shutterstock / sakkmesterke This is a preview of Launchpad, our free weekly…

Dark matter is the biggest missing piece in our understanding of the cosmos. Despite substantial evidence that dark matter accounts for 85% of all matter in the Universe, there is currently no consensus on its nature. This covers whether dark matter particles may collide with other particles like atoms or…

TAMPA, Fla. — NanoAvionics is preparing to ship a nanosatellite slated to launch this fall to study black holes and neutron stars from low Earth orbit, the Lithuanian manufacturer announced Aug. 7. The company provided its 6U satellite platform for the NinjaSat mission, and integrated it with a payload from…

BBC ordered to end TV licence 'farce' (Image: Getty) Campaigners are accusing the BBC of hounding over-75s who refuse to pay their TV licence. They claim the corporation repeatedly sends “threatening” letters to those rebelling against the scrapping of the freebie three years ago. One elderly refusenik has been slapped…

An artist's impression of a black hole. Could these cosmic monsters devour the entire universe? (Image credit: MARK GARLICK/SCIENCE PHOTO LIBRARY via Getty Images) Black holes are infamous for their immense gravity — they can swallow stars, planets and even other black holes.  But could a black hole consume the…

Akers had already convinced himself that the conversion program should be written in the language of quantum error correction, as Harlow had already worked out for empty space. The semiclassical interior would be the message, and the quantum exterior would be the transmission. And given that the interior seemed to…

One of the universe’s most unusual phenomena is black holes. The chirping sound that two black holes make when they merge can be heard using gravitational-wave detectors; about 70 such chirps have been discovered so far.  The “ocean of voices” in which chirps are thought to predominately occur in two…
