The Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) is home to many interdisciplinary projects which benefit from the synergy of a wide range of expertise available at the institute. One such project is the study of black holes that could have formed in the early universe, before stars and galaxies were born.

Earth just got 7 km/s faster and about 2000 light-years closer to the supermassive black hole in the center of the Milky Way Galaxy.

Dark matter has so far defied every type of detector designed to find it. Because of its huge gravitational footprint in space, we know dark matter must make up about 85 percent of the total mass of the universe, but we don't yet know what it's made of.

Astronomers have assumed for decades that the Universe is expanding at the same rate in all directions. A new study based on data from ESA's XMM-Newton, NASA's Chandra and the German-led ROSAT X-ray observatories suggests this key premise of cosmology might be wrong.

Understanding the how our universe came to be what it is today and what will be its final destiny is one of the biggest challenges in science.

Moving through cosmic forests and spider webs in deep space in search of answers on the origin of the Cosmos.

A Fossil From The Big Bang

A relic cloud of gas, orphaned after the Big Bang, has been discovered in the distant universe by astronomers using the world's most powerful optical telescope, the W. M. Keck Observatory on Maunakea, Hawaii.

Galactic Archaeology

The star Pristine 221.8781+9.7844 is one of the oldest stars in the Milky Way. We know this because of its atmosphere.

Researchers at the University of Bonn and the University of California at Irvine used sophisticated computer simulations to devise a test that could answer a burning question in astrophysics: is there really dark matter?

University of Groningen astronomers have discovered relics of merger events in the Milky Way halo.

The first stars in the universe blazed to life about 200 to 400 million years after the big bang.

Scientists reveal correlated flow of particles emerging from even the lowest-energy, small-scale collisions at Big-Bang particle collider.

How The Universe Became Filled With Light

Soon after the Big Bang, the universe went completely dark.

Astrophysicists have a fairly accurate understanding of how the universe ages.

Astronomers have just made a new measurement of the Hubble Constant, the rate at which the universe is expanding, and it doesn't quite line up with a different estimate of the same number.

Tracing The Cosmic Web

Galaxies in the universe trace patterns on very large scales; there are large empty regions (called "voids") and dense regions where the galaxies exist.

Download And 3-D Print Your Universe

Researchers have created a 3D printed cosmic microwave background - a map of the oldest light in the universe - and provided the files for download.

The universe suddenly looks a lot more crowded, thanks to a deep-sky census assembled from surveys taken by NASA's Hubble Space Telescope and other observatories.

Two papers published by an assistant professor at the University of California, Riverside and several collaborators explain why the universe has enough energy to become transparent.

An international team led by Japanese researchers has made a 3D map of 3000 galaxies 13 billion light years from Earth, and found that Einstein's general theory of relativity is still valid.
