A series of five astronomical image panels in blue scale, showing the same patch of sky over time from 2017 to 2021, observed with various telescopes such as CFHT, DECam, HSC, GMOS-N, and PS1. Each panel shows subtle changes in the brightness of the targeted transient.

But perhaps none surpasses the stunning emission nebula known as the Fighting Dragons of Ara, the Rim Nebula, or simply NGC 6188.

Fascinating: They look like cosmic companions, but Arp 4 is a cosmic illusion: one galaxy is ~65 million light-years away and the other is ~675 million

Interactions between the two galaxies create delicate streams that visibly link the pair.

A large spiral galaxy is seen in the center of the frame. It's tilted at an angle, so that it's disk appears as an oval rather than a circle. Dramatic dust lanes cross in front of the center of the galaxy and are backlit by a haze of yellow-white stars. Above the spiral is a smaller disk galaxy seen in shades of blue white. It appears to be at almost a right angle to the large spiral, falling into the larger galaxy. The two galaxies are connected by a bridge of dusty tendrils, which are also backlit by the main galaxy. This galaxy pair looks a lot more 3D than most interacting galaxies because of their angles and the backlighting effect.

Measurement of the Half-Light Radius for the Tucana Dwarf Spheroidal Galaxy. Pei-Jun Huang et. al. https://arxiv.org/abs/2512.12027
Cropped view of Tucana Dwarf from stacked $i$, $r$, $g$ band images, captured by DECam, processed with the LoVoCCS processing pipeline. Figure 2 $r$-$i$ vs. $g$-$r$ color-color diagram used to filter for objects consistent with stellar sources in the Tucana Dwarf galaxy. The solid curves show the upper and lower bound criteria for which we made our selection of sources. Spatial distribution of objects excluded in color cut selection, outside of first central annulus for which HST data is used. Grey elliptical curves show boundaries for elliptical bins.

Gemini &Blanco Telescopes Unlock Clues to Origin of Longest Gamma-ray Burst Ever Observed

Data acquired with multiple NSF NOIRLab facilities indicate gamma-ray burst lasting over seven hours resides in a massive, extremely dusty galaxy

iopscience.iop.org/article/10.3...
noirlab.edu/public/news/...
Left: The stellar field around the host galaxy of GRB 250702B — the longest gamma-ray burst that astronomers have ever observed. It comprises observations from the Gemini North telescope, one half of the International Gemini Observatory, funded in part by the U.S. National Science Foundation and operated by NSF NOIRLab, as well as the U.S. Department of Energy-fabricated Dark Energy Camera, mounted on the NSF Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory, a Program of NSF NOIRLab. Right: Close-up view of the host galaxy taken with the Gemini North telescope. This image is the result of over two hours of observation, yet the host galaxy appears extremely faint due to the large amount of dust surrounding it. The DECam data were acquired on 3 July 2025. The Gemini North data were acquired on 20 July 2025. Credit: International Gemini Observatory/CTIO/NOIRLab/DOE/NSF/AURA Image processing: J. Miller (International Gemini Observatory/NSF NOIRLab), M.
