Massive stars much bigger than our sun always come in pairs or groups, not alone. But astronomers don't fully understand how these groupings form. In a new study, astronomers using ALMA have ...

Using the Hubble Space Telescope (HST), astronomers have observed a nearby ultra-diffuse galaxy designated F8D1. The new observations, presented July 17 on the pre-print server arXiv, deliver ...

This gas led to the formation of stars and expansion of galaxies during the early stages of the Universe. A new study by an ...

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 ...

The first stars were massive, hot, and bright, forming from primordial clumps of hydrogen and helium. They lived fast and died young, but not before producing new elements in their stellar remains ...

The region, called Terzan 5, was previously thought to contain two generations of stars.

Theorists have long wondered how massive stars–up to 120 times the mass of the Sun–can form without blowing away the clouds of gas and dust that feed their growth. But the problem turns out to be less ...

This study explores the complex metallicity gradient of the spiral galaxy NGC 1365 using a new ultrahigh-resolution technique for measuring spectra across galaxies in three dimensions. This method ...
