"#SpaceX satellites threaten to hide asteroids that pose danger to humanity
The International Astronomical Union demands that urgent action be taken against the uncontrolled proliferation of these devices. #Starlink satellites make it difficult to search for objects at risk of impacting the Earth"
Sun and moon combo: I finally got some OK skies overnight last night and few enough clouds to shoot through during the day today to get another moon/sun combo. These images were captured a little over 9 hours apart.
Une troisième soirée d'astro qui s'annonce ? Pour cela il faudrait que les brumes de chaleur se dissipent. La plupart des sites météo le disent, mais pour l'instant ça tarde... #Astrodon#astronomie#telescope
How are we building the largest #telescope dome ever? In the latest episode of Chasing Starlight we take you on a behind-the-scenes tour of the dome of ESO's Extremely Large Telescope in #Chile
It's 88 m wide and 80 m tall, and it will shelter the ELT and its optics & instruments from the harsh environment of the Atacama Desert –– a true feat of #engineering

The sun and moon captured about 6 hours apart on April 23. The sun was super active with tons of sunspots and the moon was 100% full. I captured the moon right after it cleared the trees and the color is unedited.
Both were captured from my backyard with my QHY168C camera and EQ6-R mount. I used a homemade solar filter with Thousand Oaks film for the sun shots.
One of my students’ #edtech projects was to research #accessibility tools that we could 3D print for others in our school. One of the tools that we ended up #3dprinting was a microscope phone mount for our science classes.
This also was great mounted on my #telescope today at home as we got ready to look at the #eclipse with a solar filter. Much easier to share and talk about what we see as well as take photos and videos. Accessibility options benefit everyone.
[#SpaceSuccess] Following ESA's de-icing operation, the #Euclid satellite has gained 15% in optical sensitivity!
All satellites are assembled on Earth, in clean rooms whose humidity is close to 50°C. As it is propelled into space, its various components gradually cool down... and water condenses. To encourage evaporation, radiators have been installed in Euclid's instrument bay and the mirrors of the #telescope ...

#Euclid is a #space#telescope 🛰️ to escape #Earth's atmosphere, absorbing infrared-radiation and creating wobbly images. But space also has "weather". Given the currently active #sun 😎 and warnings of "geomagnetic storms" here's an intro blog post into "space weather" 🌪️ and how it affects the #ESAEuclid satellite.
I never thought I'd write a Vim plugin, but working on an ever-growing CSS file that can't be split has made me creative. With https://github.com/gbirke/telescope-foldmarkers.nvim I can now use the excellent Telescope extension to jump between sections in my file where I have put fold markers. A table of contents for an otherwise unstructured file! #Vim#neovim#telescope
