Here is an interesting piece. A project using a radio telescope in Australia to look for "technosignatures", ie. signals from extrasolar civilizations, had a possible signal left after filtering out thousands of other candidates. The article describes the detective work they did to try to determine its origin and whether it really was a legitimate candidate. (Spoiler: It wasn't.) This really points up the fact that unless first contact consists of something obvious like an alien spacecraft cruising right up to us a la numerous movie versions of it, it may actually be a long and laborious process.

Technosignature from Proxima Centauri — and why astronomers rejected it

The forensic analysis of a potential signal from another civilization reveals how challenging the search for extraterrestrial intelligence is likely to become.

And I am now getting a regular newsletter from Astronomy magazine so expect to see articles from it starting to pop up on here more often.
 
If one is looking for a signal that is logical ... would and icons originating from earth fail to the most part considering our leaning towards emotionalism? That's a bimbo-like sign right? May come from a fey essence denied the freedom of educational forces ...

Appears to be the norm over time ... thus cultured ignorance! So the alien can't find us ... strange provocation of thoughts beyond norm!

Why would intelligence even desire to come here ... unless forced? Could be temporal ...
 
And she's off. James Webb Space Telescope is now in space en route to it's location orbiting the Earth-Sun L2 Lagrange point. It is not a slam dunk, since there's some complicated maneuvering that has to happen and then the delicate operation of opening the telescope's sun shield (which blocks light and infrared from the sun). But at least it is off the ground and heading in the right direction.

Telescope go bye-bye. Webb leaving Earth.

NASA's Webb Telescope Launches to See First Galaxies, Distant Worlds - NASA

Editor’s note: This release was updated on Dec. 25 to reflect the observatory’s release at approximately 870 miles (1,400 kilometers).

2021 goes out on a sad night in the world of astronomy. Carolyn Shoemaker, who discovered or co-discovered 32 comets and over 800 asteroids, has died at 92. Many of her discoveries were made in partnership with her husband, the late geologist and planetary science pioneer Eugene Shoemaker. Perhaps their most famous discovery was Comet Shoemaker-Levy which spectacularly crashed into Jupiter in 1994. While she did not even start in astronomy until she was in her fifties, Carolyn Shoemaker made important contributions to the field.

On their 2020 album Human||Nature, Nightwish paid tribute to Eugene with the song Shoemaker, but the sentiments and title of the song work just as well for Carolyn.

 
There's a great page on NASA's website where you can see the progress of the James Webb Telescope to the L2 Lagrange point. It is currently about 57% or the way there and they have deployed the sunshield, which now has to be tensioned.

Where Is Webb? NASA/Webb

During Webb's launch, deployment and commissioning, 'WhereIsWebb' tracked Webb's 'flight' to L2 orbit, its state and progress during its deployment and commissioning process, and finally the release of its first images. This process is now complete. During this process, the page constantly...

Why a sunshield? Webb is going to do much of its observing in the infrared band and heat from the sun would interfere with some of the very weak, distant IR sources they are looking at/for. So the designers have it facing away from the sun with a multilayer reflective barrier on the "bottom" to block infrared from the sun.
 
IR is not all that cool in the light of considerations of science! Iris for short to satisfy publishers ... they are in the business for words they really don't care for the unseen missals ... darker forms!
 
This month marks 3 months in space for the Shenzhou 13 crew on the Chinese space station. This is a highlight reel from CGTN, a Chinese media source. Very much in the vein of what we would see from a similar mission in the ISS with public lectures, spacewalks to do work on the station (including setting up their version of the Canadarm), and testing remote control of their cargo capsule, which is used when they need to move a spacecraft to a different docking port or if there are problems when the cargo capsule leaves to return to Earth. ISS does the same with its cargo craft sometimes.

Tianhe, where the taikonauts are living and working, is only the first module of the planned Tiangong space station. The two laboratory modules are due to be launched this year, one in Spring and one in late Summer. Crew missions are planned for 180 days so this crew should be coming home in April or so, though no undocking date is announced yet. Shenzhou 14, carrying the next crew, is probably going up around the time the next module goes up in May.

 
Doing some further reading, I see that China has a space telescope similar to Hubble that will orbit near the space station so crews from the station can maintain it, much as NASA used to use the shuttle to maintain Hubble. So not a fourth module strictly speaking, but a closely associated second structure. Planned launch is 2024.
 
As science is privatised the west ... in the east it is nationalized in a very solid and pious way!

Such is the hard hand that republicans wish to win ... without much intelligence of the consequences as heavenly gnomes and elves come round out of sight!

There may be more to this than appears (and thus incarnate quality)! One has to understand incarnate as a word ... like God ... unseen virtue?

Folks have trouble seeing this as it clearly is a transparent resolution ... how to free ourselves from such closed concepts???? Portal of escape is questionable ... something open to inquiry ... do tell?
 
I recently joined the James Webb Observatory and Astronomy Facebook group. I am not sure when this group started but some people are choosing not to follow the rules of the group. Besides cool astronomy pictures and stuff, it provides more data for me on group dynamics today on Facebook: sad but interesting.
 
I'm sort of listening for things about the Chinese rocket booster that somehow escaped, and is due to crash on the far side of the moon, I believe, tomorrow.
 
It used to be Chinese citizens that worked at escaping. It is almost funny that a rocket booster escaped.
 
As Scott Manley suggested, better it falls there than on someone's house (happened once after a Chinese launch).
 
And the painstaking work of aligning the James Webb Space Telescopes mirror segments is done, and the first images from alignment testing are out. And they are spectacular. Looks like NASA pulled it off.
