I normally avoid all reporting about 3I 'alien' BS, even highly critical stories, to not grant it even more popularity - but this concise response may come handy when Your Crazy Uncle (TM) next time tells you NASA is covering up an alien invasion ...

Yay, a 6th sighting of comet Lemmon for me this evening from Bochum, Germany - bridge camera at max. zoom, 3.2 seconds at f/2.8 and ISO 1600. See www.facebook.com/media/set/?v... for the other five evenings since 20 October.

One analytical model shows that, as of November 5th, the dismantling of U.S.A.I.D. has already caused the deaths of 600,000 people, two-thirds of them children. https://newyorkermag.visitlink.me/jUzNSc

Hello Sentinel-1D! 👋 Yesterday the satellite launched into orbit, and Meteosat-12's FCI instrument was ready to capture the moment from space. Below: views in the 0.6µm channel (L) and (R) Rocket Plume RGB, revealing the rocket’s exhaust plume in the both visible and infrared range. 🚀

For years, but especially for the past year, Democrats have been in thrall to the idea that they need to chase an imagined median voter, and adopt that voter’s positions. Mamdani’s victory shows another way: hold principles, and persuade people to share them.

New Jersey and Virginia have chosen well by electing @mikiesherrill.bsky.social and @spanbergerforva.bsky.social as their next governors! They are proven leaders who won by focusing on what matters most - how politics and policy can make everyday life better and more affordable.

Scott Tingle is the 19th astronaut to be appointed chief, succeeding his former space station crewmate, Joe Acaba.

A #SolarFlare from active region AR14274 has capped out around the X1.8-class level. Not bad, but I expect we'll see something stronger than this before the week is done!

Seems about right

That escalated quickly ... the 'debate' about (generative) AI has met Godwin's Law. Seriously, have the critics - valid as many arguments may be - already lost it completely, just ~3 years after genAI for the masses arrived?

A trio of monster active regions have rotated into view over the Sun’s eastern horizon. Whilst the front of the Sun has been quiet for a while, these regions were producing significant activity on the Sun’s backside. They will rotate to face Earth later this week. #spaceweather

Open Sesame! The ELT doors have moved for the first time. This was no small feat, as each door will weigh 650 tonnes once completed. The ELT dome & its doors will guard the telescope from the harsh conditions of the Atacama Desert. https://www.eso.org/public/videos/potw2544a/ 🔭 🧪 📹 ESO/ACe

They don't make comets like this anymore ... (Although I've seen countless fake 'nightscape' montages of tiny Lemmon pasted over landscapes that make it look like this.)

ISRO successfully launched the GSAT-7R/CMS-03 satellite aboard the LVM3-M5 mission! Weighing 4,410kg (which makes it the heaviest GEO satellite to be launched from India), the multi-band satellite is based on the I-4K satellite bus and will be used by the Indian Navy.

Exactly 25 years ago, at 09:21 UTC, the era of continuous human presence on the International @Space_Station began. Since Crew One took up residence in 2000, 21 @esa.int astronauts have lived and worked on this orbital outpost, conducting essential research to benefit life on Earth.
