Astronomers analyzing data from Vera C. Rubin Observatory have discovered the fastest-ever spinning asteroid with a diameter ...

Young star systems, like nearby Fomalhaut, are messy places. Rocks slam together and icy bodies shatter. Dust fills the space where solid objects once moved quietly along. This chaos is how planets ...

With the vastness of the Universe, everything in it seems so spread out. But some objects are closer than you might realize. Every now and then, a random interstellar asteroid passes through the Oort ...

Comet 3I/ATLAS is a rare visitor passing briefly through our solar system. Here’s how to find it in the night sky—and what you’ll need to catch a glimpse.

This image presents a grid of color-enhanced astronomical observations, each depicting a circumstellar disc—structures of dust and gas surrounding stars. Every square in the grid represents a ...

Stunning new photos show the pieces of the "other ATLAS," C/2025 K1, breaking apart in space after the golden comet suddenly exploded earlier this month. When you purchase through links on our site, ...

New measurements of radio galaxies reveal that the solar system is racing through the universe at over three times the speed predicted by standard cosmology. Using highly sensitive data from multiple ...

Astronomers have spotted an intriguing cluster of objects in the Kuiper belt, the enormous, donut-shaped region of icy objects beyond the orbit of Neptune. This latest “inner kernel” was identified by ...

The Kuiper belt, a disc of icy rocks on the outermost edges of the solar system, seems to have more structure than we thought. In 2011, researchers found a cluster of objects there on similar orbits ...

Astronomers have reportedly discovered a skyscraper-sized asteroid moving through our solar system at a near record-breaking pace. The asteroid, named 2025 SC79, circles the sun once every 128 days, ...

Ernest Opik, an Estonian astronomer based at the Astronomical Observatory in Tartu from 1921-1944, commenced research on the frequencies and speeds of meteors and comets in the 1920s. In 1932, Opik ...

It’s time for stargazers to turn their telescopes toward the night sky. October is setting the stage for two cosmic visitors. Two newly discovered comets, C/2025 A6 Lemmon and C/2025 R2 SWAN, will ...
