Kreutz comet MAPS was photographed by JWST !!! A truly great image for this one!

Michael Mattiazzo reported a mini outburst of this comet this night ! It could barely visible to the naked eye.

🚨: new comet 6AC4721 is a fragment of the Kreutz group, still located at 2 AU of Sun
6AC4721 on the PCCP = Type I Kreutz sungrazer.
Perihelion 2026 April 4.
Hope it will survive unlike comet C/2024 S1 Atlas so it will put a great show !

Hominin fossils from Morocco may be close ancestors of modern humans The jawbone of an ancient hominin found at Grotte à Hominidés in Morocco Hamza Mehimdate, Programme Préhistoire de Casablanca Fossils nearly three-quarters of a million years old, discovered in North Africa, may belong to a common ancestor of Neanderthals, Denisovans and modern humans that lived shortly before the three hominin lineages split. It is thought that the last common ancestor of modern humans, Neanderthals and Denisovans lived sometime between 765,000 and 550,000 years ago.

It seems I got mixed up ,my apologies. I had object P12iFHr in mind, not P22jItr.

LHS 1140 b would’ve made much more sense than Kepler-22b 🙂

Nice tail ! P12iFHr has a retrograde, very eccentric, Halley-type orbit with a perihelion in the main belt. Happy new year Taras !

Shout out to everyone who made 2025 the most exciting year yet for NSF–DOE Rubin Observatory! 🎉

This year, Rubin completed its construction phase, entered operations, and revealed its first images during Rubin First Look. We couldn't have done it without all of you! 🔭

I think the new year will be full of a large, unprecedented number of new comets, thanks to the Vera C. Rubin Observatory scheduled to be launched in the coming months. For visual observers there is always a blind spot for observatories and telescopes, which is a good gap for discovering comets.

Went to Glenshee yesterday and it was busy due to nice weather. Saw lots of Mountain Hares but no Ptarmigan. Returned early this morning in freezing mist with no one around and quickly got lucky!

I'm currently trying to find any undiscovered Arabic observations of this supernova 🌟

Very excited! When will it be published?

Happy December Solstice! 🌞

It’s summer at NSF–DOE Rubin Observatory in Chile! Wildflowers? Blooming. Skies? Clear. Sun? Vibing. ☀️

Sending warm thoughts to the northern hemisphere! ❄️

A wide view of the planet Mars fills the frame, shown as a curved, rust-colored world against black space. The bottom edge fades into darkness, marking the planet’s night side, while the upper portion is brightly lit by sunlight. Near the right side are three large, round volcanic mountains of the Tharsis region, each with a wide circular base and a darker central caldera, resembling shallow craters pressed into the surface. North of these volcanoes, stretching almost vertically across the upper right half of the planet, lies Noctis Labyrinthus and Valles Marineris: an immense system of deep canyons and fractured terrain that appears as pale, branching scars and cracks, partly softened by hazy, cloud-like atmospheric features. Near the center of the image, positioned between the volcanoes and the canyon system, a small dark oval appears against Mars’s surface. This is Phobos, one of Mars’s satellites. Its tiny size stands out sharply against the vast scale of the planet below.

Pulsar planets are rare, but this one is even rarer amongst the rare! 🔭

#JWST observed Jupiter-mass PSR J2322-2650b, finding it has a helium/carbon-dominated atmosphere, and may have carbon clouds that form diamonds.
