Astronomers have spotted an unexpectedly hot galaxy cluster in the early universe that's challenging theories of galactic evolution. The scorching cluster existed just 1.4 billion years after the Big ...

Astronomers have created the largest and most detailed 3D map yet of a glowing signal from the early universe, revealing hidden galaxies and gas from 9-11 billion years ago. By analyzing faint ...

Artist’s impression of a forming galaxy cluster in the early Universe: radio jets from active galaxies are embedded in a hot intracluster atmosphere (red), illustrating a large thermal reservoir of ...

Astronomers used subtle warps in galaxy shapes to map the invisible forces shaping the universe. By reanalyzing years of telescope images, they studied more than 100 million galaxies across an ...

Astronomers seem to have pulled back a new curtain on the early universe. A massive 3D map now shows a "sea of light" that ...

A powerful "gamma-ray burst" has been seen exploding from merging neutron stars hidden within a previously unknown mini-galaxy leftover from an ancient cosmic crash. The "collision within a collision" ...

New 3D map of the early universe from HETDEX reveals faint hydrogen light linking galaxies 9 to 11 billion years ago.

For over 10 years, an international team of astronomers have been scanning the sky with a special telescope called the Low Frequency Array (LOFAR), which sees the world through radio waves – a kind of ...

Four galaxies crowd the center of a collapsing structure 1.4 billion years after the Big Bang. Each one is churning out stars at a pace that defies comparison with the present-day universe. Around ...

A new study, published in The Astrophysical Journal, finally changes that. Using data from the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX), researchers built a three-dimensional map of ...
