So much about galaxies remains a mystery. We know what they're made of and that we live in one (the Milky Way), but how many galaxies are in the universe?

It’s not yet December, but NASA is already in a festive mood: the Webb and Hubble space telescopes recently imaged MACS0416, a pair of colliding galaxy clusters 4.3 billion light-years from Earth that is bedecked in sparkling lights.

We now know how far away some galaxies are in the iconic "deep field" image from NASA's James Webb Space Telescope. A Canadian instrument is revealing more about how the universe changed over time.

A look at the night sky at any time of year will reveal a faint band of light stretching across the sky -- our solar system's home, the Milky Way. How much do we really know about it?

A new photo from the Hubble Space Telescope captures a face-on view of the Spanish Dancer galaxy, formally known as NGC 1566, located in the Dorado constellation.

A research team relies on measuring the number of galaxy members to determine the mass of galaxy clusters. One of the most pressing questions in cosmology is, “How much matter exists in the universe?” An international team of scientists has now succeeded in measuring the total amount of matter fo

Pioneering research using galaxy clusters has revealed crucial insights into the Universes expansion and the mysterious force propelling it using the mass-richness relation to calculate the combined mass of sampled groups, showing how larger collections house a more significant number of galaxies.

An immense bubble of galaxies, one billion light years wide and located 820 million light-years away, could be fossilized remains of the Big Bang.

The XRISM spacecraft will observe a "rainbow" of X-rays emitted by massive space objects using its state-of-the-art Resolve instrument.

XRISM, a new mission to study X-ray signals stemming from violent explosions and scorching cosmic locations, will launch on Saturday (Aug. 26) to assist scientists studying the evolution of our universe.
