University of California astronomers, including three from UCLA, have resolved a mystery about the early universe and its first galaxies.

The positively charged particles may have an outsize influence on the properties of neutron stars and other neutron-rich objects.

In an international collaboration between Japan and Sweden, scientists clarified how gravity affects the shape of matter near the black hole in binary system Cygnus X-1.

A thin gap has been discovered on the Hertzsprung-Russell Diagram (HRD).

A team of astronomers has discovered a new way to unlock the mysteries of how the first galaxies formed and evolved.

For nearly a century, astronomers have puzzled over the curious variability of young stars residing in the Taurus-Auriga constellation some 450 light years from Earth.

Observations made by researchers using a National Science Foundation (NSF) detector at the South Pole and verified by ground- and space-based telescopes have produced the first evidence of one source of high-energy cosmic neutrinos.

Einstein's understanding of gravity, as outlined in his general theory of relativity, predicts that all objects fall at the same rate, regardless of their mass or composition.

Astronomers have discovered a special kind of neutron star for the first time outside of the Milky Way galaxy, using data from NASA's Chandra X-ray Observatory and the European Southern Observatory's Very Large Telescope (VLT) in Chile.

Capitalizing on the unparalleled sharpness and spectral range of NASA's Hubble Space Telescope, an international team of astronomers is releasing the most comprehensive, high-resolution ultraviolet-light survey of nearby star-forming galaxies.

A Yale-led research group has created the most detailed maps yet of a vast seedbed of stars similar to Earth's Sun.

Scientists agree the sun will die in approximately 10 billion years, but they weren't sure what would happen next...until now.

How stripped-envelope supernovas lose that outer envelope is not entirely clear.

An Australian-led group of astronomers working with European collaborators has revealed the "DNA" of more than 340,000 stars in the Milky Way, which should help them find the siblings of the Sun, now scattered across the sky.

Strands In A Cosmic Web

Scientists have decoded faint distortions in the patterns of the universe's earliest light to map huge tubelike structures invisible to our eyes - known as filaments - that serve as superhighways for delivering matter to dense hubs such as galaxy clusters.

A Dead Star, Circled By Light

Spectacular new pictures, created from images from both ground- and space-based telescopes, tell the story of the hunt for an elusive missing object hidden amid a complex tangle of gaseous filaments in the Small Magellanic Cloud, about 200 000 light-years from Earth.

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.
