Scanning the first images of a well-known early galaxy taken by NASA’s James Webb Space Telescope (JWST), Cornell astronomers were intrigued to see a blob of light near its outer edge.
It all started around 13.8 billion years ago with a big, cosmological “bang” that brought the universe suddenly and spectacularly into existence. Shortly after, the infant universe cooled dramatically...
The supersharp radio "vision" of the U.S. National Science Foundation's Very Long Baseline Array has revealed previously unseen details in a jet of material ejected at three-quarters the speed of...
In the 13.8 billion-year-old universe, most galaxies form gradually, reaching their large mass relatively late.But the National Science Foundation-funded discovery of a massive rotating disk gala...
By harnessing the extreme sensitivity of the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have directly observed a pair of Milky Way-like galaxies seen when the universe was only e...
A new, large-scale computer simulation has shown for the first time that large disk galaxies, much like our own Milky Way, may have existed in the early days of the universe.
The Atacama Large Millimeter/submillimeter Array (ALMA) has detected the most distant clouds of star-forming gas yet found in normal galaxies in the early Universe. The new observations allow astronom...
We present a high signal-to-noise spectrum of a bright galaxy at z = 4.9 in 14 h of integration on VLT FORS2. This galaxy is extremely bright, i850 = 23:10  0:01, and is strongly-lensed by the foregr...
The acoustic peak in the cosmic microwave background power spectrum is sensitive to causal processes and cosmological parameters in the early universe up to the time of last scattering. We provide lim...
Light from tiny galaxies more than 13 billion years ago played a larger role than previously thought in creating the conditions in the universe as we know it today, according to a new study by researc...
Light from tiny galaxies over 13 billion years ago played a larger role than previously thought in creating the conditions in the universe as we know it today, a new study has found. Ultraviolet (UV) ...
Pasadena, CA— New work from a team of scientists including Carnegie’s Josh Simon analyzed the chemical elements in the faintest known galaxy, called Segue 1, and determined that it is effectively a fo...
University of Hawaii at Manoa astronomer Regina Jorgenson has obtained the first image that shows the structure of a normal galaxy in the early universe. The results were presented at the winter Ameri...
To perform imaging observation of optically red objects such as high redshift quasars and brown dwarfs, the Center for the Exploration of the Origin of the Universe (CEOU) recently developed an optica...
The chemistry of the early Universe is a fascinating field of study. Even in the absence of any elements heavier than lithium, a surprising degree of chemical complexity proves to be possible, giving ...
