Deep inside Perseus A

An international team of researchers has imaged newly forming jets of plasma from a massive black hole with unprecedented accuracy.

Astronomers using NASA's Hubble Space Telescope have for the first time precisely measured the distance to one of the oldest objects in the universe, a collection of stars born shortly after the Big Bang.

The Most Distant Star Ever Seen

Thanks to a rare cosmic alignment, astronomers have captured the most distant normal star ever observed, some 9 billion light years from Earth.

The universe is full of mysterious exploding phenomena that go boom in the dark.

In the Universe, galaxies are not distributed uniformly. There are some places, known as clusters, where dozens or hundreds of galaxies are found close together.

Water is crucial for life, but how do you make water? Cooking up some H2O takes more than mixing hydrogen and oxygen.

Hubble Finds Relic Galaxy Close To Us

Astronomers have put NASA's Hubble Space Telescope on an Indiana Jones-type quest to uncover an ancient "relic galaxy" in our own cosmic backyard.

Astronomers have used NASA's Hubble Space Telescope to uncover a vast, complex dust structure, about 150 billion miles across, enveloping the young star HR 4796A.

This spectacular and unusual image shows part of the famous Orion Nebula, a star formation region lying about 1350 light-years from Earth.

The new MATISSE instrument on ESO's Very Large Telescope Interferometer (VLTI) has now successfully made its first observations at the Paranal Observatory in northern Chile.

In the 1980s, scientists started discovering a new class of extremely bright sources of X-rays in galaxies.

For the first time, astronomers have detected a signal from stars emerging in the early universe.

A research team has published a new study lead by Pat Roche, professor of astrophysics at The University of Oxford, and Chris Packham, associate professor of physics and astronomy at The University of Texas at San Antonio.

A Window Into The Cosmic Past

This image from the NASA/ESA Hubble Space Telescope shows the galaxy cluster PLCK G004.5-19.5.

Astronomers have used NASA's Hubble Space Telescope to make the most precise measurements of the expansion rate of the universe since it was first calculated nearly a century ago.

In an unprecedented deep survey for small, faint objects in the Orion Nebula, astronomers using NASA's Hubble Space Telescope have uncovered the largest known population of brown dwarfs sprinkled among newborn stars.

A new international study involving The Australian National University (ANU) has found a plane of dwarf galaxies orbiting around Centaurus A in a discovery that challenges a popular theory about how dwarf galaxies are spread around the Universe.

The study presents the discovery of one of the stars with the least content of "metals" (heavy elements) known.

Stars forming in galaxies appear to be influenced by the supermassive black hole at the center of the galaxy, but the mechanism of how that happens has not been clear to astronomers until now.

When scientists recorded a rippling in space-time, followed within two seconds by an associated burst of light observed by dozens of telescopes around the globe, they had witnessed, for the first time, the explosive collision and merger of two neutron stars.
