This artist’s rendering shows LuSEE-Night atop the Blue Ghost spacecraft scheduled to deliver the experiment to the far side of the moon. A 3D map of space, with streams of light pointing in different directions from a central focal point. Researchers took detailed images in 20 different directions on the sky, creating a 3D map of 700,000 objects and covering roughly 1% of the total volume DESI will study. The Dark Energy Spectroscopic Instrument (DESI) atop Kitt Peak. Still frame from a black and white video that shows Georges Lemaître, a man with short hair and glasses, at the end of the interview. The roof of the Dark Energy Spectroscopic Instrument opens up to reveal a starry night sky. Members of science team lined-up in a water tank after the outer detector installation. Smiling person in front of a chalk board Scientific data plot. The earth is in the lower left, looking out in the directions of the constellations Virgo, Serpens and Hercules to distances beyond 5 billion light years. As this video progresses, the vantage point sweeps through 20 degrees towards the constellations Bootes and Corona Borealis. Each colored point represents a galaxy, which in turn is composed of 100 billion to 1 trillion stars. Gravity has clustered the galaxies into structures called the “cosmic web”, with dense clusters, filaments and voids. Photo - A new study has found that a share of particles that has gone missing is most likely located at the distant bounds of galaxy haloes. The study found some of these particles of baryonic matter located about 6 million light-years from their galactic centers. This color-rendered image shows the halo of the Andromeda galaxy, which is the Milky Way’s largest galactic neighbor.
