PRE-PERIHELION STUDY OF #COMET #3IATLAS with our findings about its spectroscopic similitude with CR carbonaceous chondrites. Manuscript submitted for publication in which we propose it is a #TNO-like body experiencing #cryovolcanism
Now in Cornell Univ. @arxiv repository:

COMET #24P/Schaumasse still well located in #Bootes this morning. It is in +9.5 V magnitude and exhibiting an amazing green coma despite of the #FullMoon.
An excellent target, the charts to find it right now:

This is one of my favorite JWST observation ever! 🔭 💙

This is HH288, a star heavier than the Sun being born in front of our eyes! The jets are the result of that process. There is even another star being born near it, as the perpendicular jets are showing.

HD: flic.kr/p/2rUKqvx
Two jets, appearing red and violet, being ejected by a central protostar, hidden behind gas. The jets are extending to the left and right parts of the image. Two perpendicular thinner jets can be seen as well, coming from another protostar. Hundreds of stars can be seen in the background of the image, appearing like bright dots with the JWST trademark diffraction spikes.

A recent study in Nature Astronomy reports a phenomenon never seen before and completely unexpected: a bow shock around the white dwarf RXJ0528+2838, the dense remnant of a low-mass star. 🔭

False-color image made with MUSE on the VLT: right in the middle of a square frame edged in white, you see the bright white dwarf as it travels through space. Around it spreads this striking bow shock nebula in vivid colors — the outermost curve shines a deep red from hydrogen emission (Hα), while closer in you get those greens from singly-ionized nitrogen ([N II]) and blues coming from doubly-ionized oxygen ([O III]). A few extra bright patches dot the area nearby. The whole central scene is placed over a wider background filled with soft reddish stars, which gives the picture a nice dramatic feel.

Editor's choice: Neights et al. have observed a gamma-ray burst that lasted 7 hours. They argue it arose from a black hole merging with a helium star. ☄️🔭 #highenergyastro #stellarastro

The Pleiades star cluster (M45) captured over 25 hours. The blue glow is starlight reflecting off interstellar dust. The surrounding brown structures are the Integrated Flux Nebula, incredibly faint clouds lit by the glow of our entire galaxy.

Yes, one image from space can change humanity’s perspective

Although we might not think about it often, simply looking at a single image from space can shift the perspective of even the most hard-hearted of humans.
