A jet from a young star created an expanding bubble that collided with the star's protoplanetary disk. Astronomers have found these explosive bubbles before, but never one that's collided with the disk. What does this mean for planet formation?

Massive galaxies like the Milky Way have smaller satellite galaxies that are tidally disrupted and absorbed. Astronomers think this is how galaxies assemble hierarchically. New research examines galaxies much less massive than the Milky Way to see if they also have their own, much less massive satellites.

As space becomes more important to the economy of nations around the world, the risk of paper mills flooding the literature with fraudulent results is increasing.

This chunky star projector is a good choice for kids thanks to its low price and easy-to-use functions.

What are these gigantic blue arcs near the Andromeda Galaxy (M31)?

Both science fiction and real life have some interesting spacecraft names, sometimes borrowing from each other. This quiz will test to see if you know the difference.

The rate of human-produced light is increasing in the night sky by as much as 10% per year, making it difficult for astronomers to study the night sky.

Twin orbs of superhot plasma at the Milky Way's center known as the "Fermi bubbles" contain inexplicable clouds of cold hydrogen, new research reveals.

Napoleon's campaign against the Russian Empire was one of the most costly wars in history. Many soldiers died of diseases. Some of these illnesses are only now being identified

The 2025 full 'Sturgeon Moon' graced the night sky on Aug. 9.

Spot Saturn near the moon on Aug. 11! See them with the naked eye and learn what to expect through a telescope.

Imagine building an entire city on the Moon using nothing but sunlight and lunar soil! Chinese scientists have made this science fiction dream a reality by creating a revolutionary machine that acts like a solar powered 3D printer, melting lunar soil at temperatures exceeding 1,300°C to create strong construction bricks. This technology could transform space exploration by eliminating the need to transport heavy building materials from Earth, making lunar bases not only possible but affordable.

Technicians have successfully installed two sunshields onto NASA’s Nancy Grace Roman Space Telescope’s inner segment. Along with the observatory’s Solar Array Sun Shield and Deployable Aperture Cover, the panels (together called the Lower Instrument Sun Shade), will play a critical role in keeping Roman’s instruments cool and stable as the mission explores the infrared universe.

A new executive order repeals a 52-year-old ban on commercial supersonic flights, while new technology can make supersonic flight quieter than ever before.

In a Q&A interview, author and science writer David Baron discusses the turn-of-the-century Mars craze, which he covers in his new book, "The Martians."

Earth has endured, and been shaped by, a constant rain of material from elsewhere in the Solar System. Some of the material was large, like the Chicxulub asteroid that ended the dinosaur's reign. But most of it is in the form of tiny micrometeorites. Those tiny rocks hold clues to Earth's ancient atmosphere.

August sees all of the naked eye worlds excepting Mars hiding in the dawn. Set your alarm, and you can uncover Mercury through Saturn all in the dawn twilight sky, crowned with a fine close conjunction of Jupiter and Venus on Tuesday, August 12th. You can see the changing scene each morning starting this weekend, as the two get ever closer from one morning to the next.
