The NOT team expresses its sincere condolences on the passing of Prof. Francisco Sánchez, founder of @iacastrofisica.bsky.social.

His vision and determination were instrumental in establishing the Canary Islands as a world-class site for astronomy, where the NOT has proudly stood since 1989.

🥹 We are proud to announce that the WG on Small Body Nomenclature of @iau.org.web.brid.gy has named two main belt asteroids after our colleagues Peter Brandt (1954-2025) and Markku Verkkoniemi (1962-2004).

🎶 New paper in @aanda-journal.bsky.social using FIES data validates a method to measure stellar masses via seismic waves

😀 Led by Jeppe S. Thomsen, a former NOT student, with contributions from NOT staff, students & users

⭐ A big step for asteroseismology!

😢 The NOT family is very sad to share that Peter(Pedro) Brandt passed away yesterday

Pedro worked as a mechanic on the mountain for 35 years and is probably the person who has been in most physical contact with the telescope: www.not.iac.es/news/Pedro.html

Our special thoughts go out to his family

📢 𝗜𝗠𝗣𝗢𝗥𝗧𝗔𝗡𝗧 📢 The Nordic Optical Telescope invites applications to the Johannes Andersen Student Programme.

👩‍🎓👨‍🎓 We are looking for students who can start around end of 2025 or from early 2026 and onwards: not.iac.es/general/stud...

⏳ Attention! The deadline is Friday, September 15, 2025 #ORMLaPalma

⏰ 𝗜𝗠𝗣𝗢𝗥𝗧𝗔𝗡𝗧: only 5 days left to deadline for observing time in Period 72, October 1, 2025 - April 1, 2026. #ORMLaPalma

🔭 NOT helps uncover one of the most distant GRBs ever — a message from the early Universe.

💥 J=20.85 mag NOTCam source seen 12h after burst. VLT found z~7.3. Signal came when the Universe was 0.73 Gyr old—possibly from one of the first stars turning into a black hole.

🪨 The NOT tracked asteroid 2024 YR4 to check its risk to Earth!

🔭 Data from ex-NOT students Zuri Gray & Grigori Fedorets, now at @helsinki.fi helped refine its orbit—dropping impact odds from 3% to 0.001%.

🌕 It’s more likely to hit the Moon now—4%!

#ORMLaPalma #asteroid #2024YR4

The NOT helps unveil a dramatic fate: a pair of white dwarf stars, spiraling together in a death dance that will end in a Type Ia supernova... and they're just 150 light-years away!

🪨 The NOT is participating in the follow-up of asteroid 2024 YR4 to refine the probability of impact in 2032.

🔭 A team led by @esa.int researcher Marco Michelli has improved the parameters of the asteroid's orbit.

🤔 Did you know who discovered NOT? Liisi Oterma was the first Finnish woman to get a PhD in Astronomy. She discovered > 200 SSSBs, including 3 asteroids named Lapalma, Muchachos and NOT!

👩‍🔬 Sergio Armas & Julia Martikainen have written about her in the local press to celebrate #WomenInScience Day.

🍿 Plan for the weekend! Our observers Cameron Lemon and Nikki Arendse from the Oskar Klein Centre in Sweden made a high quality documentary footage during their last visit to NOT.

🔭 Thank you for this great outreach action!
