Peek inside ESO's Extremely Large Telescope (ELT), under construction in #Chile 's Atacama Desert. The main structure shown here will host the ELT’s five mirrors, which will gather the light and send it to the instruments at the sides of the telescope.

With its 39-metre-diameter, the main mirror will be the largest ever for an optical telescope: the biggest eye on the sky!

This image shows the interior of the Extremely Large Telescope's (ELT) dome. The telescope structure, supported by struts, takes up most of the image in the centre, with some cranes around working. The gigantic doors of the dome are open, allowing sunlight to shine through.

Bad news for UK astronomy and particle physics communities as research council looks to make 30% cuts on top of 15% cuts made already. Impact assessments have been asked to be made for a 60% cut to budgets

https://ras.ac.uk/news-and-press/news/proposed-budget-cuts-catastrophe-uk-astronomy

This makes me very concerned for those looking to start careers in the field and how the UK will lose key talent and expertise

Most hashtags are pretty obvious, you just put # in front of a topic. For example if a post is about coffee it might have the tag #Coffee

However, many popular hashtags have difficult-to-guess names, so I've started a list to help people discover them:

➡️ https://fedi.tips/fun-and-useful-hashtags-to-follow-on-mastodon-and-the-wider-fediverse

Copy-paste a hashtag into the search box in Mastodon if you want to browse or follow it.

If you have suggestions for non-obvious hashtags that should be added to the list, let me know in the replies 🙂

So, "Deutschland-Tour" Daten komplett. Ich spreche voraussichtlich am

* 23 & 24 April in Berlin
* 29 April in Nürnberg
* 8 Mai in Stuttgart

Werden jeweils etwas verschiedene Vorträge sein bei denen es sich um Schwarze Löcher und Astronomie dreht, aber immer allgemeinverständlich - ähnliches Niveau wie mein Buch. Mehr Details kommen später, aber vielleicht will sich jemand schon mal den Tag vormerken.

Excited to share my first #SpaceAustralia feature article for 2026 about an exciting and ambitious project that is unfolding 1km below the surface in regional Victoria.

Last year, I had the incredible opportunity to visit the Stawell Underground Physics Laboratory (SUPL) with Dr Katie Mack and explore the ambitious efforts of the SABRE South experiment. Shielded from cosmic rays by a kilometre of rock, this lab offers the ideal conditions to search for the faint whispers of dark matter, which still accounts for 25% of all matter in the Universe—and yet remains completely undetected.

Check out the article (and yes, check out our funky boots in the clean room!) and keep a lookout for exciting news of the detectors switching on later in 2026.

Australia’s Dark Matter Quest | Spaceaustralia

A kilometre beneath the surface of regional Victoria, scientists are preparing to switch on one of Australia’s most ambitious physics experiments. Nearing completion, the facility will soon host a sensitive dark matter detector designed to search for elusive particles thought to make up a quarter of the Universe’s mass. Dr Katie Mack and Rami Mandow visited the site to see the project taking shape.
