For decades, astronomers have wondered what the very first stars in the universe were like. These stars formed new chemical elements, which enriched the universe and allowed the next generations of ...

Using the James Webb Space Telescope, a team of astronomers studied the properties of a planet-forming disk around a young and very low-mass star. The results reveal the richest hydrocarbon ...

Astronomers call this "eruptive mass loss," and it's a stellar drama we're still trying to fully grasp.

Massive stars have always puzzled scientists—how do they grow so quickly despite fierce radiation pushing material away? New high-resolution ALMA observations suggest that instead of relying solely on ...

Astronomers have long known that neutron stars, the crushed cores left behind after massive stars explode, should be scattered throughout the Milky Way galaxy. However, most of them are effectively ...

Map of material distribution in the disk around protostar G358-MM1. The white “+” marks the location of the protostar. The contour lines indicate signal strength. The colors represent the ...

Besides being a point of light, a star is a luminous, spherical mass of plasma, enough to hold itself together under its own gravity. On its own, though, gravitational rounding isn't enough. What ...

It’s “common knowledge”—and the scare quotes should be a warning—that the sun is an average star. But it’s not, and in fact it’s not even close: The sun is in the top 90th percentile of stars by mass.

Chemistry in the first 50 million to 100 million years after the Big Bang may have been more active than we expected. When you purchase through links on our site, we may earn an affiliate commission.
