A groundbreaking discovery has shed new light on star formation in the early universe, revealing a galaxy that forms stars at ...

In the constellation Cygnus, a bright knot of stars seems to adorn one edge of a nearly perfect 20-light-year-wide circle, ...

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 ...

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 discovery indicates how galaxies could have grown quickly when the universe was very young, solving a long-standing ...

An international team of astronomers reports the discovery of a new dusty star-forming galaxy at high redshift. The newfound ...

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 ...

The newborn planetary system appears to be emerging 1,300 light-years away around a baby star known as HOPS-315. Planet-forming materials were first identified using NASA's James Webb Space Telescope.

Astronomers have identified a rare type of binary star system containing a rapidly spinning millisecond pulsar and a helium star companion, formed via common envelope evolution. Although such systems ...

Heavy water detected in the disk of V883 Orionis; chemical signature reveals that some of the water formed before the star ...

A new study suggests that during a potential phase of primordial matter domination, particle interactions may have led to the formation of the universe’s first compact cosmic objects. Less than a ...
