The title says it all. I'd like anyone who wants to post and discuss space news here.
To begin with...

1. JWST first images will not look the way we expect them to
As the setting up of 18 golden segments has already begun, there is a question: what first images are going to look like?

"The first images are going to be ugly. It is going to be blurry. We'll [have] 18 of these little images all over the sky". - Rigby told reporters during a livestreamed press conference on Saturday (Jan. 8) discussing the successful deployment of Webb's 21.3-foot-wide (6.3 meters) primary mirror that day. Rigby was speaking from NASA's Goddard Space Flight Center in Maryland, where telescope operations are centered.
There was nothing said about the publishing of first "ugly" images. But it's expected that on ~Day 120 of the mission (April 24) the telescope is going to see more precisely, because tha alignment will be completed.

3. Physicists have claimed the possible existence of a multiverse

Physicists from France and Switzerland have explained the inconsistencies in the standard model of physics with the existence of the multiverse.

The standard model of physics does not explain the accelerating expansion of the universe. Moreover, the mass of the Higgs boson predicted by this model is at least three times greater than that obtained in the experiments of scientists.

Physicists Raffaele Tito D'Agnolo of the French University of Paris-Saclay and Daniele Terezi of CERN explained the second inconsistency with the existence of a multiverse.
Scientists have suggested that during the formation of the Universe, there were many other parallel universes. The distribution of Higgs bosons between different universes and their regions was not uniform: some regions contained heavy bosons, while others contained lighter ones.

The researchers saw that as they evolved, the multiverses that contained the heavy Higgs boson quickly became unstable and collapsed in a short amount of time — about 10^−5 seconds. That is, under the influence of dark energy, the expansion of the Universe was replaced by a sharp contraction, and it “collapsed”.

Thus, according to scientists' research, there is only one universe containing a very light Higgs boson left.

1. Volcano ash

Having experienced the greatest volcanic eruption in 30 years, Tonga Volcano ash went into the atmosphere at the record altitude. Fortunately, it has not done any harm to Earth's climate.
Satellites detected the ash cloud, which has already spread over Australia, at over 24 miles (39 kilometers) above Earth's surface, Oxford University research fellow Simon Proud said on Twitter on Monday (Jan. 17). This was the first time volcanic ash has been detected so high in Earth's atmosphere, he added.


"Based on analysis of data from global weather satellites, our preliminary data for the Tonga volcanic cloud suggests that it reached an altitude of 39km [24 miles]," Proud said. "We'll refine the accuracy of that in the coming days, but if correct, that's the highest cloud we've ever seen."

2. Virtual astronaut

Amazon’s Alexa is about to become the first ever virtual astronaut. It is going to be tested on Artemis 1.

Lockheed Martin announced Jan. 5 that it has been working with Amazon and Cisco on a project called Callisto that will be flown on the Artemis 1 mission launching no earlier than March. Callisto is a demonstration to see how Amazon’s Alexa technology and Cisco’s Webex teleconferencing platform could be used on future crewed missions.


3. UK rocket maker makes fuel out of plastic wastes

UK rocket making company Skyrora has created ecofuel, called Ecosene using plastic wastes. The experiments has shown that is 1-3% better than kerosene according to its energy characteristics.
