A new study argues that dark matter and dark energy might be illusions caused by the universe’s forces fading over time. For ...

When looking up at the sky, you might think galaxies have always looked the way they do today. But a new study from Princeton University and published in the journal, Monthly Notices of the Royal ...

The James Webb Space Telescope found a surprisingly large galaxy, nicknamed "The Big Wheel," in the early universe. This galaxy formed much faster than current theories predict, challenging our ...

Astronomers may have uncovered the origins of the mysterious “little red dots,” some of the strangest galaxies seen in the early universe. These tiny but brilliant objects, discovered by the James ...

PHOENIX – NASA has chosen the University of Arizona to lead a space telescope mission meant to better understand how galaxies and stars form. The space agency awarded $20 million to the Aspera mission ...

The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming ...

An artist’s impression of the “Cosmic Grapes” galaxy, composed of at least 15 massive star forming clumps—far more than current theoretical models predict could exist within a single rotating disk at ...

Why Sagittarius B2 produces so many stars in comparison to the rest of the galactic center has remained an enduring mystery ...

The red shade shows the atomic hydrogen gas content of the galaxy, overlaid on the optical image. The atomic gas that is outside the white circle does not contribute significantly to the formation of ...

The Milky Way could have many more satellite galaxies than scientists have previously been able to predict or observe, according to new research. Cosmologists at Durham University used a new technique ...

The CiELO project’s results are intended to complement and enhance the interpretation of data from telescopes such as NASA's James Webb Space Telescope (shown). Photo by NASA Aug. 12 (UPI) --Chile's ...
