Astronomers have used a planet-hunting satellite to see a white dwarf abruptly switching on and off for the first time.

The majestic spiral galaxy NGC 4666 lies about 80 million light-years away in the constellation Virgo and is undergoing particularly intense star formation.

In October 2019, a high-energy neutrino slammed into Antarctica.

Seeking The Star Stuff That Made Us

At the 2021 Fall Meeting of the APS Division of Nuclear Physics, two independent research groups will unveil new measurements aiming to explain the birth of half the universe's elements.

Experiments will give scientists a closer look at how exploding stars create world's heaviest elements.

Hubble Detects A Dangerous Dance

Their delicate galactic dance takes place more than 100 million light-years from Earth. The lower galaxy, NGC 5953, is tugging at NGC 5954, which appears to be extending one spiral arm downward.

A new study showing how the explosion of a stripped massive star in a supernova can lead to the formation of a heavy neutron star or a light black hole resolves one of the most challenging puzzles to emerge from the detection of neutron star mergers by the gravitational wave observatories LIGO and Virgo.

This sparkling starfield, captured by the NASA/ESA Hubble Space Telescope's Wide Field Camera 3 and Advanced Camera for Surveys, contains the globular cluster ESO 520-21 (also known as Palomar 6).

This beautiful image shows a glowing horseshoe-shaped cloud of hot gas against a backdrop of thousands of stars in the Large Magellanic Cloud, a nearby galaxy.

"Molten Ring" Galaxy Prompts New Research

Hubble Space Telescope's glamour shots of the universe are so revealing they nearly always have a discovery behind them.

Early massive galaxies--those that formed in the three billion years following the Big Bang--should have contained large amounts of cold hydrogen gas, the fuel required to make stars.

This composite X-ray (blue)/radio (pink) image of the galaxy cluster Abell 400 shows radio jets immersed in a vast cloud of multimillion degree X-ray emitting gas that pervades the cluster.

Sounds From Space

Space is mostly quiet. Data collected by telescopes is most often turned into silent charts, plots, and images.

These new views showcase the dual nature of the star AG Carinae, which was the target of the NASA/ESA Hubble Space Telescope's 31st anniversary image in April 2021.

Galaxies can receive and exchange matter with their external environment thanks to the galactic winds created by stellar explosions.

Scientists connect the dots between where planets form and what they're made of.

A 900-year-old cosmic mystery surrounding the origins of a famous supernova first spotted over China in 1181AD has finally been solved, according to an international team of astronomers.
