A new image from the Dark Energy Camera peels back the layers of a “galactic onion” whose shells extend 150,000 light-years across space.
Jam packed issues filled with the latest cutting-edge research, technology and theories delivered in an entertaining and visually stunning way, aiming to educate and inspire readers of all agesThe Dark Energy Camera captured the onion-like layers of the shell galaxy NGC 3923, located about 70 million light-years from Earth.
A new image from the Dark Energy Camera peels back the layers of a"galactic onion" whose shells extend 150,000 light-years into space. on the Víctor M. Blanco 4-meter Telescope at the Cerro Tololo Inter-American Observatory in Chile, which is operated by the U.S. National Science Foundation . NGC 3923 exhibits symmetrical, onion-like layers that likely formed from a galactic merger, in which a larger galaxy slowly siphoned"The shells of NGC 3923 make the galaxy quite exceptional," officials said in the statement."Not only does it have the largest known shell of all observed shell, but it also has the largest number of shells and the largest ratio between the radii of the outermost and innermost shells.
Rare 'Einstein cross' warps light from one of the universe's brightest objects in this stunning image "Its shells are also interestingly symmetrical, while other shell galaxies are more skewed," officials said in the statement."These uncommon features are a sublime example of the unique structures that galaxies can embody depending on their specific evolutionary conditions." Camera image also captures a handful of other galaxies and a large gravitational lens around the galaxy cluster PLCK G287.0+32.9, located near the top of the image.

Growing in molasses: Cosmic large-scale structure caught growing slower than expectedThe large-scale structure of the universe—the gigantic, hierarchical cosmic web of structures bound by gravity—is mostly made up of dark matter. The growth of the large-scale structure, from individual galaxies to galaxy clusters, cosmic voids and filaments (Fig. 1), revolves around a competition: Gravity pulls matter together while dark energy pushes space apart. The distribution and evolution history of matter and large-scale structure therefore provide an avenue to study the properties and nature of dark matter, gravity and dark energy.

Dark matter could be annihilating inside white dwarfsAs the search for dark matter particles continues to yield nothing, astronomers continue to look at ways these elusive particles might be found. One general method is to look for evidence of dark matter particle decay. Although dark matter doesn't interact strongly with regular matter, some dark matter models predict that dark matter particles can interact with each other, causing them to decay into regular particles.
