Giant Comet Found in Outer Solar System by Dark Energy Survey
Estimated to be 100–200 kilometers across, the unusual wandering body will make its closest approach to the Sun in 2031

Zooming on Comet Bernardinelli-Bernstein. This zoom shows an image from the Dark Energy Survey (DES) composed of some of the discovery exposures showing Comet Bernardinelli-Bernstein collected by the 570-megapixel Dark Energy Camera (DECam) mounted on the Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory (CTIO) in Chile.
In 29 new scientific papers, the Dark Energy Survey examines the largest-ever maps of galaxy distribution and shapes, extending more than 7 billion light-years across the Universe. The extraordinarily precise analysis, which includes data from the survey s first three years, contributes to the most powerful test of the current best model of the Universe, the standard cosmological model. However, hints remain from earlier DES data and other experiments that matter in the Universe today is a few percent less clumpy than predicted.

The ICARUS detector has been collecting test data in preparation for the official start of the physics data collection later this year. The left panel shows an electron neutrino interaction that produced a proton (top track) and an electron, which produced an electromagnetic shower with photons and electrons (bottom tracks). The right panel shows a muon neutrino interaction that produced a proton (short track, top left) and a muon (3.4-meter-long track); a cosmic-ray track independent of the muon neutrino interaction is also visible in the lower half of the image. In both panels, the neutrino beam came from left. (Image: ICARUS collaboration)
