Angled from the upper left corner to the lower right corner is a cone-shaped orange-red cloud known as Herbig-Haro 49/50. This feature takes up about three-fourths of the length of this angle. The upper left end of this feature has a translucent, rounded end. The conical feature widens slightly from the rounded end at the upper right down to the lower right. Along the cone there are additional rounded edges, like edges of a wave, and intricate foamy-like details, as well as a clearer view of the black background of space. In the upper left, overlapping with the rounded end of Herbig-Haro 49/50, is a background spiral galaxy with a concentrated blue center that fades outward to blend with red spiral arms. The background of space is speckled with some white stars and smaller, more numerous, fainter white galaxies throughout.

NEW: #NASAWebb reveals a distant spiral galaxy perfectly aligned near the tip of Herbig-Haro 49/50—an outflow generated by a nearby still-forming star. This near- and mid-infrared image uncovers intricate details about how stars form: webbtelescope.pub/4iGQg9K 🔭 🧪

🔭 We're ready with the DESI DR1 database and 23 million spectra in the SPARCL searchable spectral database. These services are best suited for public access for astronomy questions and we worked closely with the DESI data team 🤝

@desisurvey.bsky.social has *two* big releases

1) Exciting results with stronger hints of evolving dark energy based on three years of data

2) First year of data (DR1): spectra for >18 million objects in the main survey! At the Data Lab, we provide a database version for convenient data access 🔭✨

A large galaxy is at center, and a significantly smaller galaxy is to its left. The large galaxy, nicknamed the Bullseye, is mostly face-on, but the top appears slightly tilted away. It has several rings. Its circular core is bright white at the very center, but light yellow overall. Going outward, there are gaps between the rings. The core is surrounded by two slightly lighter yellow rings, which also appear to be overlapping. The next ring is slightly more transparent and yellow. The two or three rings that are farther out are bluer, sometimes with blue clumps. The widest ring is also blue, but also the most transparent. At 9 o’clock is a small dwarf galaxy. It is about the same size as the yellow core of the Bullseye. The dwarf galaxy is blue, with many dots. It looks like the edge of the Bullseye might touch the dwarf galaxy. Both galaxies are set on the black background of space, which is dotted with a range of galaxies in different shapes, colors, and sizes.

Bullseye! Researchers using Hubble found a massive galaxy rippling with nine star-filled rings after an “arrow,” the blue dwarf galaxy to its center-left, plunged through its core 50 million years ago. A thin trail of gas still links the pair: bit.ly/4hcX52n 🔭 🧪

PSA: if you're going to #AAS245 in Washington DC.

There is a sample of #asteroid #Bennu on display at the Smithsonian National Museum of Natural History! Also a Mars meteorite you can *touch*! #ToBennuAndBack
