It's 2.42am. The rain forecast has proven to be accurate. No chance of capturing Orion this morning. Perhaps another day. Back to bed. Have a good night and Thursday everyone :) 🔭 🧪

NGC 40 is a planetary nebula located about 5300 ly away in the constellation of Cepheus. Quite visible is the central star of this PN. This star is the former core of the progenitor star. No longer undergoing fusion it will cool slowly over billions of years. #astronomy

This neat little study examined a reported very early case of #SpaceWeather from the Sun affecting 1800s technology (trains). Turns out a small typo in an old Nature article attributed solar activity to a delayed train, but that wasn't the case. Nice little science / history investigation! 🔭🧪

Did Space Weather Delay the 10:05 p.m. Train Departure From Exeter on 18 October 1841?

A reported 1841 train delay in England attributed to geomagnetic disturbance is inconsistent with the opening date of the railway affected The integration of contemporary observations and archiva...

Just a piece of NSF–DOE Rubin Observatory's Ocean of Stars 🌊✨ This galaxy is called MCG-06-33-009, and the blue knots in its spiral arms show where hot, young stars are forming. 🔭🧪 Rubin will capture billions of galaxies and enable scientists to study how galaxies grow and change 🌀

Golden spiral galaxy with blueish spiral arms in a dense star field. Numerous orange and blue stars dot the dark sky, with a bright bluish star left of center and faint background galaxies scattered throughout.

A wide, panoramic view of a dense field of pinpoint stars filling the entire frame like fine dust. A white square notes a specific galaxy near upper center. Wispy, grayish-brown clouds of galactic cirrus drift across the scene, creating a subtle, patchy texture over the dark background. Several brighter stars stand out, most notably a large, brilliant blue star on the upper right surrounded by a soft glowing halo, along with a few other scattered bright blue and warm orange stars.

Avec toutes vos zolies photos, je crois que je peux dire que je vois très bien la supernova aaiv a l'oeil à l'oculaire. Avec deux galaxies en plus de 7331. Et dans le meme champ de vu: le quintet de stephan. Jolie spectacle! 🔭

Martial Relier @martialrelier.bsky.social

à mon tour de faire une photo de NGC 7331, dans la constellation de Pégase. L'étoile marquée par les traits rouge est une supernova : SN 2026aaiv, découverte le 1er septembre. 🔭 #astrophotography

Throwback post: Our friends at Kitt Peak (home of DESI and NEID) also got a spectacular view of the Lunar eclipse. Note the "tiny" dot in the Southeast starting at 15 seconds! #Astronomy

The new lunar impact also created a big new cold spot on the Moon. Seems that the incoming asteroid loosened up the Moon dust, so it doesn't hold heat as well. Nighttime temperatures around McGetchin crater are about 8 degrees C colder than its surroundings. 🧪🔭 www.science.org/doi/10.11….

Rain is being forecast here early tomorrow morning. I'll still get up around 3am. Just in case I get the chance to capture Orion. 🔭 🧪 #astrophotography

Wow: Giant new impact crater spotted on the Moon! An asteroid the size of an apartment building hit the lunar surface in early 2024 & created 220-meter (730-foot) wide McGetchin crater. It's "the largest contemporary impact crater found in the Solar System." 🧪🔭 science.nasa.gov/solar-sy….

Officially named McGetchin after pioneering lunar scientist Tom McGetchin, the crater formed on the Moon’s eastern edge sometime between April 11 and May 22, 2024, after a comet or asteroid the size of a three- to six-story building hit the surface.

The crash left a crater, 728 feet wide, that spans the length of two football fields. And at 141 feet deep, the crater could fit three vertically stacked yellow school buses. Scientists estimate that an impact of this magnitude happens on the Moon about once in a century or even longer.
