The Shenzhou-12 crew, astronauts Nie Haisheng (commander), Liu Boming and Tang Hongbo, opened the hatch and entered the Tianhe core module on 17 June 2021, at 10:48 UTC (18:48 China Standard Time). Shenzhou-12 (神舟十二号) will spend three months attached to the Tianhe core module (天和核心舱), the first and main component of the China Space Station (中国空间站), informally known as Tiangong (天宫, Heavenly Palace).

Quantum computers developed to date have been one-of-a-kind devices that fill entire laboratories. Now, physicists at the University of Innsbruck have built a prototype of an ion trap quantum computer that can be used in industry. It fits into two 19-inch server racks like those found in data centers throughout the world. The compact, self-sustained device demonstrates how this technology will soon be more accessible.
Over the past three decades, fundamental groundwork for building quantum computers has been pioneered at the University of Innsbruck, Austria. As part of the EU Flagship Quantum Technologies, researchers at the Department of Experimental Physics in Innsbruck have now built a demonstrator for a compact ion trap quantum computer. “Our quantum computing experiments usually fill 30-to 50-square-meter laboratories,” says Thomas Monz of the University of Innsbruck. “We were now looking to fit the technologies developed here in Innsbruck into the smallest possible space while meeting standards commonly used in industry.” The new device aims to show that quantum computers will soon be ready for use in data centers. “We were able to show that compactness does not have to come at the expense of functionality,” adds Christian Marciniak from the Innsbruck team.
The individual building blocks of the world’s first compact quantum computer had to be significantly reduced in size. For example, the centerpiece of the quantum computer, the ion trap installed in a vacuum chamber, takes up only a fraction of the space previously required. It was provided to the researchers by Alpine Quantum Technologies (AQT), a spin-off of the University of Innsbruck and the Austrian Academy of Sciences which aims to build a commercial quantum computer. Other components were contributed by the Fraunhofer Institute for Applied Optics and Precision Engineering in Jena and laser specialist TOPTICA Photonics in Munich, Germany.
A new study takes a look at how the presence of a surface can affect an exoplanets atmosphere, giving astrobiologists a way to study exoplanet surfaces without having to “see” them directly.
We could do it with the James Webb Space Telescope—but we’d also need to return to the unfiltered curiosity we had as teenagers.
Goldman Sachs ramps up bitcoin trading in new partnership with Mike Novogratz’s Galaxy Digital.
The bank has begun trading bitcoin futures with Galaxy Digital, the crypto merchant bank founded by Mike Novogratz, CNBC has learned.
The trades represent the first time that Goldman has used a digital assets firm as a counterparty since the investment bank set up its cryptocurrency desk last month, according to Galaxy co-president Damien Vanderwilt.

The environmental setting makes all the difference.
After the launch of Tiangong space station’s core module in April, China took on its next challenge: send astronauts to live there.
The crew of Shenzhou-12 successfully docked at Tiangong this week, and will stay on board for 3 months.
First astronauts enter China’s Tiangong space station.
The three took up residence in the core module hours after the Shenzhou 12 launch craft lifted off from the Gobi Desert.
The first astronauts for China’s new space station blasted off Thursday for the country’s longest crewed mission to date, a landmark step in establishing Beijing as a major space power.
