The Dark Energy Survey

The Antlia galaxy cluster is a group of at least 230 galaxies held together by gravity; this cluster is unusual -- unlike most other galaxy clusters, it appears to have no dominant galaxy within it.

This week, learn secrets unlocked by studying Ludwig van Beethoven's hair, explore lava tubes where Stone Age people lived, see the cosmic "God's Hand," and ...

The Dark Energy Camera has imaged a ghostly hand claw reaching out to grab a distant galaxy. There's nothing supernatural about this structure known as...

An enormous new image of the ghostly Vela supernova remnant shows off the fascinating and elaborate structure of this striking cosmic object.

This colorful web of wispy gas filaments is the Vela Supernova Remnant, an expanding nebula of cosmic debris left over from a massive star that exploded about 11,000 years ago. Located around 800 light-years away in the constellation Vela (the Sails), this nebula is one of the nearest supernova remnants to Earth. Though the unnamed star ended its life thousands of years ago, the shockwave its death produced is…

Using the Canada France Hawaii Telescope (CFHT), Chinese astronomers have performed multi-band observations of a merging dwarf galaxy known as VCC 322. Results of the observational campaign, presented March 4 on the preprint server arXiv, deliver crucial information regarding the nature and properties of this galaxy.

This NASA/ESA Hubble Space Telescope image features Arp 122, a peculiar galaxy that in fact comprises two galaxies – NGC 6040, the tilted,

Researchers at Swinburne University of Technology have contributed to a landmark study that complicates our understanding of the universe.

The new tension, centered around a value for cosmic lumpiness known as S8, could join the Hubble tension in dethroning our best picture of how the universe evolved.

While hunting for dark matter, astronomers accidentally discovered the first known stellar stream stretching between galaxies. The trail of stars is also the...

Using the Gemini North Telescope located near the Mauna Kea mountain in Hawaii, the team behind the research spotted galactic cannibalism in action near the ...

NASA's James Webb Space Telescope is expected to complement a part of the Euclid spacecraft's mission to unveil the nature of dark energy.

The New Horizons mission currently flying through the Kuiper Belt could be facing an unexpected change of plans.

The New Horizons mission currently flying through the Kuiper Belt could be facing an unexpected change of plans. NASA's Science Mission Directorate is soliciting input on turning the spacecraft into a heliospheric science probe. The agency wants to do it much sooner than mission planners intended. If that happens, it will stop further planned planetary exploration of objects in that distant regime of the solar…

Supernova (SN) 185 occurred in 185 CE in the direction of Alpha Centauri, between the constellations of Circinus and Centaurus.

The tattered shell of the first-ever historically recorded supernova was captured by the US Department of Energy-fabricated Dark Energy Camera, which is mounted on the National Science Foundation's (NSF) Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF's NOIRLab. RCW 86's ring of debris is all that remains of a white-dwarf star that exploded more than 1800…

Scientists release newly accurate map of all the matter in the universe

Dark Energy Camera Plane Survey took two years to conclude.

Astronomers have released a gargantuan survey of the galactic plane of the Milky Way. The new dataset contains a staggering 3.32 billion celestial objects — arguably the largest such catalog so far. The data for this unprecedented survey were taken with the Dark Energy Camera, built by the US Department of Energy, at the NSF's Cerro Tololo Inter-American Observatory in Chile, a Program of NOIRLab.

A new survey of the Milky Way galaxy has unveiled 3.32 billion celestial objects, with a stunning new image that showcases stars, pillars of dust and areas of star birth.
