Scientists are building a better account of the lives of adolescent stars, starting from their births in collapsing clouds of cosmic gas and dust to the time they “fly the nest” and drift away from other young stars in their original clusters. Studying these stellar timelines will help scientists better determine the ages of stars…

Credit: Sam O’Keefe/University of Missouri A team of international scientists, led by the University of Missouri’s Dr. Haojing Yan, used NASA’s James Webb Space Telescope (JWST) to uncover 14 new transient objects within the Christmas Tree Galaxy Cluster, 4.3 billion light years away. These transients, which appear as flickering lights in space, were recognized through…

It was an unusual sight in the College of Southern Nevada’s North Las Vegas campus parking lot. People gathered outside one warm October morning, the air buzzing with anticipation. The bustle revolved around the Dale Etheridge Planetarium, in the south wing of the campus, where an annular solar eclipse event brought hundreds of visitors during…

As light passes through the upper reaches of our atmosphere, it is refracted and distorted, making it much harder to…

Asteroids often have moons, though we’ve only recently begun to record them en masse.

Forty years ago, in 1983, the Space Shuttle Columbia flew its first international spaceflight, STS-9. The mission included—for the first time—the European Space Agency’s Spacelab pressurized module and featured more than 70 experiments from American, Canadian, European, and Japanese scientists. Europeans were particularly proud of this “remarkable step” because “NASA, the most famous space agency…

An illustration of two water-rich exoplanets with hazy atmospheres. Credit: Roberto Molar Candanosa/Johns Hopkins University Scientists have simulated conditions that allow hazy skies to form in water-rich exoplanets, a crucial step in determining how haziness muddles observations by ground and space telescopes. The research offers new tools to study the atmospheric chemistry of exoplanets and…
