NGC 4254, a spiral galaxy, is resplendent in orange and blue in this Jan. 29, 2024, image from the James Webb Space Telescope. This is one of 19 nearby spiral galaxies recently imaged by the telescope as part of the long-standing ...
Ever since the James Webb Space Telescope (JWST) captured its first glimpse of the early universe, astronomers have been surprised by the presence of what appear to be more "ultramassive" galaxies than expected. Based on ...
Black holes not only existed at the dawn of time, they birthed new stars and supercharged galaxy formation, a new analysis of James Webb Space Telescope data suggests.
This NASA/ESA Hubble Space Telescope image shows a densely packed field of stars laid upon a background of dust, gas, and light from more distant celestial objects. There are so many stars in this image's field of view that ...
When did the universe start? When and how did the first stars and galaxies form? What is the fate of the universe?
A team of astronomers has found that the total mass of stars in a galaxy is not a good predictor of the galaxy's abundance of heavier elements, a surprising result according to previous studies. Instead, the gravitational ...
Employing massive data sets collected through NASA's James Webb Space Telescope, a research team led by a Rutgers University–New Brunswick astronomer is unearthing clues to conditions existing in the early universe.
This image of the softly luminous spiral galaxy UGC 11105 is from the NASA/ESA Hubble Space Telescope. It lies about 110 million light-years from Earth in the constellation Hercules.
Bayreuth scientists are investigating the structure and long-term behavior of galaxies using mathematical models based on Einstein's theory of relativity. Their innovative approach uses a deep neural network to quickly predict ...
A team of astronomers, led by Arizona State University Assistant Research Scientist Tim Carleton, has discovered a dwarf galaxy that appeared in James Webb Space Telescope imaging that wasn't the primary observation target.
