تصوير كويكب صغير من سماء أبوظبي قبل 53 دقيقة من اصطدامه بالأرض تمكن مرصد الختم الفلكي في صحراء أبوظبي من تصوير الكويكب الصغير (C0WEPC5) وذلك قبل 53 دقيقة من اصطدامه بالأرض بالقرب من "سيبيريا" في روسيا، ويظهر في الصورة كنقطة صغيره بين النجوم التي تظهر على هيئة خطوط. يشار إلى أنه

Airwave from the impact of 2024 XA1 detected at CTBTO station I45. Based on the period of the signal the source energy is about 0.02 kT TNT. With entry speed of 15.5 km/s this corresponds to an object with mass of 700 kilograms and diameter of about 0.75-1 m. #2024XA1

In einem russischen Astronomie-Forum hab ich diese Streufeldkarte zu möglichen Meteoriten gefunden. Allerdings sind im vermuteten Fallgebiet mitten im Nirgendwo zurzeit Temperaturen von -20 bis -30 Grad. #C0WEPC5 #2024XA1

A big fireball/meteor? was seen in various locations, primarily in eastern Hokkaido in Japan last night ☄️ x.com/nhk_hokkaido/s…

There's a new interstellar comet in the neighborhood! Known as 3I/ATLAS, this comet poses no threat to Earth – but it does provide a rare opportunity to study an object that originated outside of our solar system: science.nasa.gov/blogs/planetar…

Our first glimpse of comet 3I/ATLAS from Juice's science camera 😍☄️ The precious data from the mission's November observations of the interstellar comet arrived on Earth last week. Teams are now digging in to discover what they reveal. Stay tuned for updates! Read more 👉

Update on comet C/2026 A1 (MAPS)! Nicolas Lefaudeux has updated the brightness plot of Kreutz sungrazers and comet MAPS still seems to be in the "Medium Kreutz" range. However, its further brightness development will determine its fate. If MAPS follows the same rapid brightening

And a closer look at Artemis II Orion and ICPS. The animation spans the period from 03:16:18 to 03:27:31 UTC.

International Astronomical Union (IAU) The batch includes 33 new near-Earth objects (don't worry, none pose a threat!) and ~380 new worlds beyond Neptune. And this is just the start! Once Rubin's 10-year survey begins, discoveries like this will become routine.

That's us! 🌍 The Artemis II crew captured beautiful, high-resolution images of our home planet during their journey to the Moon. As Christina H Koch put it: "You guys look great."

BREAKING (not really): CCOR-2 imagery is here and we now have confirmation on what we already suspected, comet MAPS nucleus disintegrated before even reaching perihelion. Low quality video but it’ll do it just fine. Note the striking nucleus-less appearance after the 8th second.

Here we observe naked eye visible Comet C/2025 R3 PANSTARRS - taken from a remote probe in space (STEREO-A) - soon to pass in front of the Earth on April 25-26th. It has such a long tail (!), and you can see the plasma density of it is quite high compared to the solar wind! The

Day 22 of posting until a new kreutz comet is discovered, hopefully it won’t be long. Here’s mirrored video of C/2025 R3 to resemble C/2023 A3’s path in CCOR-1. Truly a MASSIVE difference, panSTARRS is nice but tsuchinshan was on another level and a comparison is not fair

11,000 new asteroids and the LSST hasn’t even begun. 😱 This year, NSF–DOE NSF-DOE Rubin Observatory will play the Universe’s largest spot-the-difference game! 👁️👁️Each night, Rubin will find ~7 million changes in the sky. 📷@VRubinObs/NOIRLab/SLAC/NSF/DOE/AURA/T. Matsopoulos
