Marenfeld, International Gemini Observatory/Jacqueline Faherty (American Museum of Natural History)/OpenSpace/Lynette Cook Astronomers have curated the most complete list of nearby brown dwarfs to date thanks to discoveries made by thousands of volunteers participating in the Backyard Worlds citizen science project. The list and 3D map of 525 brown dwarfs including 38 reported for the first time incorporate observations from a host of astronomical instruments including several NOIRLab facilities. The results confirm that the Sun s neighborhood appears surprisingly diverse relative to other parts of the Milky Way Galaxy.

There may be fewer galaxies in the universe than we thought

There may be fewer galaxies in the universe than we thought CNN 1/13/2021 By Ashley Strickland, CNN © Zolt Levay/Space Telescope Science Institute This photo shows a phenomenon known as zodiacal light. At lower left, a glowing patch extends to the upper right in the direction of Jupiter, the bright object left of center. Zodiacal light is caused by sunlight reflecting off tiny dust particles in the inner solar system the disintegrated remains of comets and asteroids. Attempts to measure how dark space is using telescopes like Hubble have been thwarted by this ambient glow. As a result, astronomers relied on NASA s distant New Horizons spacecraft to observe the sky free from zodiacal light. The faint background they measured is the equivalent of seeing a neighbor s refrigerator light from a mile away. This very wide, multi-frame panorama was taken in October 2014 at Canyon de Chelly National Monument in northeast Arizona. The zodiacal light is at left, wit

Shining a New Light on Dark Energy

IMAGE: Elliptical galaxies are generally characterized by their relatively smooth appearance when compared with spiral galaxies (one of which is to the left) which have more flocculent structure interwoven with dust. view more Credit: DES/CTIO/NOIRLab/NSF/DOE/AURA Acknowledgments: Image processing: DES, Jen Miller (Gemini Observatory/NSF s NOIRLab), Travis Rector (University of Alaska Anchorage), Mahdi Zamani & Davide de Martin The Dark Energy Survey has released a massive, public collection of astronomical data and calibrated images from six years of work. Containing data on nearly 700 million astronomical objects, this second data release in the Survey s seven-year history is the topic of sessions today and tomorrow at the 237th Meeting of the American Astronomical Society.[1]
