Evidence for a dwarf galaxy without dark matter challenges traditional galaxy formation models
FCC 224 G475 As an example of Galfit modeling. From left to right, the three panels display the original image, masked image, model, and residuals. The image shown here has three times the size of the main axis RE of the FCC 224, but the actual input image to the GALFIT includes the entire UVI chip (~155” x 75”). Credit:…

Kids datasets ultimately do not shake up the cold dark matter model, researchers say
The Omega Cam Camera is located in the heart of the VST. It is built around 32 CCD detectors that create 268 megapixel images together. The camera includes a guide and active optical system, as well as an additional CCD to control many huge color filters. The Omegacam was designed and constructed by a consortium that includes research institutes in…

The team discovers “dark oxygen” at the bottom of the sea
Credit: CC0 Public Domain Children always ask, “Why?” It’s natural to want to know more as they are the first time they’re experiencing things. But as children grow into adults, they often dismiss something new that challenges their experiences and understanding. This happened when we discovered a source of oxygen production in the deep sea, but we ignored it for…

Dark energy camera captures sparkling galaxies in the Antria star cluster
The Antria Galaxy Cluster (Abell S636) is a group of at least 230 galaxies located approximately 130 million light-years away in the direction of the Antria constellation (air pump). There are many different types of galaxies, including lenticular galaxies, irregular galaxies, and microdwarfs. This cluster is dominated by two giant elliptical galaxies: NGC 3268 (center) and NGC 3258 (bottom right).…

Two clusters of dark comets in our solar system could tell researchers where Earth’s oceans are located
Dark comets fly through space, but unlike comets, they do not have dust tails. Credit: Adina Feinstein and NASA Earth Observatory The water that makes up the oceans served as an important element for the development of life on Earth. But scientists still don’t know where the water on Earth comes from in the first place. One leading idea is…

Astronomers discover more dark comets
This artist’s concept shows the interstellar object 1I/2017 U1 (Oumuamua) discovered in 2017. Although not a dark comet per se, ‘Oumuamua’s movement through the solar system has helped researchers better understand the nature of the 14 dark comets discovered so far. Credit: European Southern Observatory / M. Kornmesser The first dark comet (an object that looks like an asteroid but…

The dark energy tearing apart our universe may not be what it seems, scientists say
The Dec. 14, 2023 image released by NOIRLab shows the sky above the Nicholas U. Mayall telescope at Kitt Peak National Observatory (KPNO), a program of NSF’s NOIRLab in Tucson, Arizona. This photo shows meteors from the Geminid meteor shower moving across the sky. Credit: NSF’s NOIRLab (via AP) An ancient galaxy far, far away is giving scientists yet another…
