Astronomers surveying the sky with NASA's Spitzer space telescope have been able to peer back to the early universe, 13 billion years in the past, and find some of the very first galaxies. They look like tiny, orange dots aglow in a sea of darkness -- not too dissimilar to the famed first image of a black hole -- but the miniscule lights imaged by Spitzer contain a host of … [Read more...] about NASA telescope spies unusual galaxies from dawn of the universe
Far out in the cosmos, a ghostly galaxy stands alone. It shines with only a faint glimmer of starlight, has hardly changed for eons — and astronomers have no idea why it's there or how it formed. DGSAT I, discovered in 2016, is an ultradiffuse galaxy (UDG), meaning it is as big as a typical galaxy but gives off very little starlight.

NASA's Dawn spacecraft, which studied two large objects in the asteroid belt, has officially run out of fuel, ending its mission to shed light on the solar system's earliest days, but the spacecraft's science legacy will live on. Dawn was the first spacecraft to orbit two different extraterrestrial bodies. The mission was technically canceled twice before the spacecraft … [Read more...] about It’s Sunset for NASA’s Dawn, But Asteroid Belt Probe’s Legacy Lives On
Inmate No. 15000-030 is released into the frigid January morning at 8:46, a gray custodial suit of sweatpants and long-sleeved thermal clinging to his immense frame, a bushy salt-and-pepper beard wrapping around his face, a guard escorting him with a high-powered rifle slung over his right shoulder. Most politicians would appear hopelessly—dangerously—misplaced in a … [Read more...] about Kent Sorenson Was a Tea Party Hero. Then He Lost Everything.
