APOD - Comet G3 ATLAS: a Tail and a Telescope
Comet C/2024 G3 ATLAS has made a dramatic appearance in planet Earth's skies. A visitor from the distant Oort Cloud, the comet reached its perihelion on January 13. On January 19, the bright comet was captured here from ESO Paranal Observatory in the Atacama desert in Chile. Sporting spectacular sweeping dust tails, this comet ATLAS is setting in the southern hemisphere twilight and was clearly visible to the unaided eye. In the foreground is the closed shell of one of the observatory's famous auxiliary telescopes. Still wowing southern hemisphere observers, the comet's bright coma has become diffuse, its icy nucleus apparently disintegrating following its close approach to the Sun.

Astronomy Picture of The Day - NGC 7814: Little Sombrero
Point your telescope toward the high flying constellation Pegasus and you can find this cosmic expanse of Milky Way stars and distant galaxies. NGC 7814 is centered in the sharp field of view that would almost be covered by a full moon. NGC 7814 is sometimes called the Little Sombrero for its resemblance to the brighter more famous M104, the Sombrero Galaxy. Both Sombrero and Little Sombrero are spiral galaxies seen edge-on, and both have extensive halos and central bulges cut by a thin disk with thinner dust lanes in silhouette. In fact, NGC 7814 is some 40 million light-years away and an estimated 60,000 light-years across. That actually makes the Little Sombrero about the same physical size as its better known namesake, appearing smaller and fainter only because it is farther away.

Supersonic Winds on Exoplanet WASP-127b Discovered
In a remarkable scientific breakthrough, astronomers have unveiled the fastest jet stream recorded on a planet to date, reaching speeds of up to 33,000 km/h (approximately 9 km/s). The study reveals that these winds travel around the equator of WASP-127b and are remarkably impactful on the planet's weather patterns. The discovery sheds light on the dynamic atmosphere of WASP-127b and provides insights into the atmospheric processes occurring on distant exoplanets.

Comet ATLAS over Brasília
What's that in the sky? Above the city, above most clouds, far in the distance: it's a comet. Pictured, the impressive tail of Comet C/2024 G3

Newly discovered group hosts two optically dark star-forming galaxies
An international team of astronomers reports the discovery of a new compact galaxy group using the Atacama Large Millimeter/submillimeter Array (ALMA). The new group, designated CGG-z4, hosts two optically dark star-forming galaxies. The finding was detailed in a research paper published(https://arxiv.org/abs/2501.05288) Jan. 9 on the pre-print server arXiv.

@MonkderVierte@lemmy.ml This is stellar death process of a planetary nebula which, after stellar death, could allow for new planetary formaiton
@cyberpunk007@lemmy.ca A carbon dust shell is a layer of carbon-rich material expelled from a star in it's later stages of life in which a star ejects these shells due to stellar instability since they are the lighter, outer elements of a star.
It's cool because JWST could even resolve detail like that!! We can also learn more about the carbon chemistry of the system, binary dynamics, and the history of the system :D
@solrize@lemmy.world Direct from Spacex, this was the Starship launch and was not going to the ISS
