Science News Roundup: Elon Musk expects Neuralink's brain chip to begin human trials in 6 months; Scientists build 'baby' wormhole as sci-fi moves closer to fact and more

Researchers announced on Wednesday that they forged two miniscule simulated black holes - those extraordinarily dense celestial objects with gravity so powerful that not even light can escape - in a quantum computer and transmitted a message between them through what amounted to a tunnel in space-time. Arianespace signs five satellites launches with European Commission Arianespace has signed a deal with the European Commission for the purchase of five launches with the Vega C launcher, the company said on Tuesday.

Elon Musk expects Neuralink's brain chip to begin human trials in 6 months

Elon Musk said on Wednesday he expects a wireless brain chip developed by his company Neuralink to begin human clinical trials in six months, after the company missed earlier timelines set by him. The company is developing brain chip interfaces that it says could enable disabled patients to move and communicate again, with Musk adding on Wednesday that it will also target restoring vision.

Scientists build 'baby' wormhole as sci-fi moves closer to fact

In science fiction - think films and TV like "Interstellar" and "Star Trek" - wormholes in the cosmos serve as portals through space and time for spacecraft to traverse unimaginable distances with ease. If only it were that simple. Scientists have long pursued a deeper understanding of wormholes and now appear to be making progress. Researchers announced on Wednesday that they forged two miniscule simulated black holes - those extraordinarily dense celestial objects with gravity so powerful that not even light can escape - in a quantum computer and transmitted a message between them through what amounted to a tunnel in space-time.

Arianespace signs five satellite launches with European Commission

Arianespace has signed a deal with the European Commission for the purchase of five launches with the Vega C launcher, the company said on Tuesday. The French group said in a statement it will launch five Sentinel satellites between 2024 and 2026 for the Copernicus program to provide Europe with reliable access to earth observation data.

Chinese astronauts board space station in historic mission

Three Chinese astronauts arrived on Wednesday at China's space station for the first in-orbit crew rotation in Chinese space history, launching operation of the second inhabited outpost in low-Earth orbit after the NASA-led International Space Station. The spacecraft Shenzhou-15, or "Divine Vessel", and its three passengers lifted off atop a Long March-2F rocket from the Jiuquan Satellite Launch Centre at 11:08 p.m. (1508 GMT) on Tuesday in sub-freezing temperatures in the Gobi Desert in northwest China, according to state television.

Distant black hole is caught in the act of annihilating a star

Astronomers have detected an act of extreme violence more than halfway across the known universe as a black hole shreds a star that wandered too close to this celestial savage. But this was no ordinary instance of a ravenous black hole. It was one of only four examples - and the first since 2011 - of a black hole observed in the act of tearing apart a passing star in what is called a tidal disruption event and then launching luminous jets of high-energy particles in opposite directions into space, researchers said. And it was both the furthest and brightest such event on record.
