"The air of an alien world lifts hopes of detecting life" by @cosmiclog / @alanboyle - #WebbSpaceTelescope🔭observations of chemistry which could be related to life come with caution not to jump to hasty conclusions. https://cosmiclog.com/2023/09/11/the-air-of-an-alien-world-lifts-hopes-of-detecting-life/ #NASA #astronomy

"Webb Discovers Methane, Carbon Dioxide in Atmosphere of K2-18 b" by @NASAWebb - 120 light years from Earth, #exoplanet #K218B needs more observation after #WebbSpaceTelescope🔭 saw atmospheric chemistry possibly consistent with life https://www.nasa.gov/goddard/2023/webb-discovers-methane-carbon-dioxide-in-atmosphere-of-k2-18b #NASA #astronomy

Cautiously interested is my attitude for now :-)

Webb Discovers Methane, Carbon Dioxide in Atmosphere of K2-18 b

"These initial Webb observations also provided a possible detection of a molecule called dimethyl sulfide (DMS). On Earth, this is only produced by life"

The white-blue stars that populate these two clusters are part of a bigger collection known as Perseus OB1. This means that these are big, hot main secuence stars that are at least more than twice as hot as our Sun.
This pair of star clusters are called Xi Persei, and popularly known as the Double Cluster. You can see this two with your own eyes, without any aid, from a dark sky.

I managed to sneak in a first light for the AT90CFT and my HAE43EC over the weekend. Lots to learn! These pictures were taken almost on a lark, so they are a variable number of 30s frames apiece with manual focusing on the Canon SL1 taken in my severely light polluted Austin TX backyard in between clouds.

Astronomers have long debated what kind of chemistry might serve as a bona fide alien biosignature. With the launch of the James Webb Space Telescope, those ideas may be put to the test.

I'm reposting some info from my 1st year seminar I am going over this week in case people haven't seen it:

This super cool video is of the Antikythera Mechanism built from Lego, including how it works! This ancient computer which tracked eclipses and important calendar dates is from Greece circa 100 BC. The original is more accurate and performed the same calculation with less pieces.

Plus d’un an sans utiliser mon matériel. Bigre tout est à re apprendre ! De la mise en station aux nouveaux logiciels en passant pas le focuser, les nouveaux colliers, le mini hub, le plate solving, le guidage, les câbles égarés, et j’en passe. Bref, une cible un peu choisie au hasard vite fait… pour de la photo. Ça fonctionne !. Ouf. 35 mn ha + 8 mn en b et v. 52 Cyg et ngc 6960

#UMPlus - Colors over the Grand Canyon

https://www.universomagico.net/2023/09/colores-sobre-el-gran-canon.html

The excellent image taken by Antoine Grelin shows the Grand Canyon, a sinuous rock formation located along the Colorado River, a colorful and steep gorge carved over millions of years in northern Arizona, United States. It is located for the most part within the Grand Canyon National Park, one of the.....

For #astronomy nerds: Today (5pm PDT) kicks off a new season of Q&A shows by @fraser where he spends an hour or two answering questions live. An edited version gets posted a few days later, but the livestream always has a bunch that gets cut for time, and you can ask your own questions about Lagrange points and black holes, too.

#CometNishimura is becoming brighter and brighter with every day and it reached "naked eye visibility".

But where is the #comet? When do I have to look at which direction?

Fear no more. I created 2 YouTube shorts to show you how to plan the observation using @StellariumDev
