Dracula's Chivito 🧛‍♂️🥪 is an edge-on protoplanetary disk discovered in 2024. #Hubble image.🛰️🔭

The name was chosen because some of the authors of the discovery paper are from Transylvania 🇷🇴 and Uruguay 🇺🇾.

A lot of comments on Mars rovers or Moon landings, but it's important to remember that the planet NASA studies most is Earth. This is less about cutting flashy things like moonwalks and more about keeping communities in the dark on climate, weather, agriculture, pollution, natural hazards, and more.

NASA's Jet Propulsion Laboratory to lay off about 550 workers

NASA's Jet Propulsion Laboratory said on Monday it will cut nearly 550 jobs as part of a restructuring, not related to the current U.S. government shutdown.

“Restructuring” because the Whitehouse and their allies choose destruction of all the good parts of the United States federal government because it won’t make them a personal profit. Also, they hate science, people who do good things for everyone instead of for them only, and actual reality.

Hubble and NuStar image of Arp 299, also known as NGC 3690.

NuSTAR data overlaid on a Hubble image of the interacting galaxy pair show the galaxy on the right has an active supermassive black hole, glowing brightly in X-rays.

Two merging galaxies form an abstract shape, which looks a little like an upside down rubber duck. Within the "head" and "body" of the duck are crossed brown swirls, which are dust and gas. The outside of the duck is outlined with hazy yellow swirls, which are streams of stars. Near the "neck" of the duck, at the point where the two merging galaxies touch, and slightly to the right is a bright white blob, surrounded by pink blobs. This is X-ray light from NuStar, which shows emission from an active supermassive black hole in the right galaxy.

Here is a fantastic summary by @fcain.universetoday.com of all the important and interesting findings that have been published about #3I/Atlas.
And surprise surprise, none of them indicate that its an alien spaceship! 🔭

One of the cartoons in my new book 'Physics for Cats' which is out now in the UK, USA, Canada, France and Germany. Order from your local bookshops or online: www.tomgauld.com/

Two beetles on a stick.
One beetle says to the other "Do you ever get the feeling we are being observed by another lifeform"
Zoom out to reveal that they are in a glass case with two scientists studying them.
One scientist says to the other "Do you ever get the feeling we are being observed by another lifeform"
Zoom out into space. Abouard a spaceship, two aliens watch the scientists on a screen.
One alien says to the other "Do you ever get the feeling we are being observed by another lifeform"
The aliens turn to look out at the reader.

👶🌟 ICYMI, Gaia released the most accurate 3D map of stellar nurseries in the Milky Way.

The map extends 4000 light-years from us, with the Sun at the centre.

Explore it here 👉 https://f.mtr.cool/lkkmqlzqih 🔭

This image captures a richly detailed section of the Milky Way, showcasing a tapestry of stars and glowing nebulas. Against a deep black cosmic backdrop, countless white stars sparkle like scattered diamonds. Wisps of reddish-pink nebulas drift across the scene, forming delicate tendrils and cloud-like structures.

Two nights of 3:45am alarms, blazing full moon lighting the sky like daytime and washing out the light of everything else, comet included. Then two days of post-processing battles, as comet processing is maddeningly tricky.

But I finally pulled it off: here is C/2025 A6 Lemmon. 🔭

Last night, NASA's Perseverance rover looked up at the night sky once more, to capture interstellar #comet 3I/Atlas flying by the red planet.

The distance was "only" 0.2 AU or 30 Mio km, far closer than the comet ever got to Earth. 🔭 #3IAtlas

Hi Paul, that streak in the Navcam image is Phobos, 3I/Atlas is way darker and not visible in these images.

See here for my processed version and comparison to Stellarium:

Simeon Schmauß @stim3on.bsky.social · 8d

Short version: left is my processesed Navcam image, right is the Stellarium simulation for the image.
The bright elongated thing is Phobos being smeared by long exposure.
Acturus and the big dipper stars are also visible. 3I/Atlas is wayyy to dim to be seen in the image.

Not sure to be honest. But since it is perfectly horizontal and pretty homogenous I'd suspect some kind of sensor or stacking artefact.

Simeon Schmauß @stim3on.bsky.social · 5d

Yes, that's the article I shared above, what are you asking?
