Astronomers have discovered a vast, dense cluster of massive galaxies just 1 billion years after the Big Bang, each forming ...

Within the image, thick clouds of cold hydrogen gas arrange themselves into ridges and wispy filaments. The deep red tones ...

Scientists are using modern technology to peer heavenward. This is an Inside Science story. Since ancient times, people gazing up at the night sky have seen animals, gods and goddesses, and other ...

The "Cosmic Grapes" galaxy formed just 900 million years after the Big Bang, revealing a never-before-seen structure.

Astronomers find galaxy Y1, a young star-forming region, revealing extreme heat just 600 million years after the Big Bang.

Stars form in the universe from massive clouds of gas. European Southern Observatory, CC BY-SA For decades, astronomers have wondered what the very first stars in the universe were like. These stars ...

Using JWST's Mid-Infrared Instrument, the scientists honed in on stars, all between one and eight times the mass of the sun, ...

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 ...

When astronomers look deep into the early universe, the expectation is simple. You should see young galaxies still assembling, with stars forming first and black holes growing later. That picture is ...

Stars usually form in clusters, which can also form in pairs or groups. Binary clusters (BCs) are defined as pairs of open clusters closely associated both in position and kinematics. They provide ...

When astronomers look deep into the early universe, they don’t expect to see fully developed cosmic objects but small galaxies, young stars, and black holes still struggling to grow. However, recent ...
