For the last few decades, researchers have been studying what the universe looked like in its first seconds. It is generally accepted that the universe expanded exponentially in the first fraction of a second after […]

Stellar streams are trails of stars that astronomers can study to solve mysteries about the history of our Milky Way galaxy and, potentially, the dark matter that helps shape the cosmos despite eluding direct observation. […]

New UNLV-led research is helping to unravel clues to a cosmic mystery that has eluded scientists for decades. Cataclysmic variables (CVs) are binary star systems in which primary stars—incredibly dense and compact white dwarfs—accumulate material […]

This March 16, 2026, image from NASA’s Hubble Space Telescope and the James Webb Space Telescope takes a closer look at the core of Messier 101, also known as the Pinwheel Galaxy.This post was originally […]

Nearly a millennium ago, astronomers witnessed a brilliant new star blazing in the sky—a supernova so bright it was visible in daylight for weeks. Today, its expanding remnant, the Crab Nebula, continues to evolve 6,500 […]

Researchers report the discovery of a Saturn-sized exoplanet orbiting two M-dwarf stars, which are smaller and cooler than our sun. The findings from this discovery were published in the The Astronomical Journal and were made […]

Using NASA’s SPHEREx space telescope, astronomers have observed remnants of the eruption of Nova Persei 1901. As a result, they detected a bipolar molecular hydrogen shell around this nova, which may be a large planetary […]

A team of astronomers led by the Center for Astrophysics | Harvard and Smithsonian have for the first time used galactic archaeology, the study of detailed chemical fingerprints in deep space, to trace the history […]

Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a nearby spiral galaxy known as NGC 628. Results of the observational campaign, published March 10 on the arXiv pre-print server, […]

New observations by a team of US astronomers have cast fresh doubt on whether the lunar surface could host abundant water ice. Publishing their results in Science Advances, a team led by Shuai Li at […]
