Hubble Hones in on a Hypergiant's Home

This beautiful Hubble image reveals a young super star cluster known as Westerlund 1, only 15,000 light-years away in our Milky Way neighborhood, yet home to one of the largest stars ever discovered.

Galaxies have dramatically grown in size since the early Universe, and elliptical galaxies, in particular, are the largest galaxies in both size and mass. What is the main driver behind the late growth of their outer parts was the question that motivated this study.

Incredibly rapid gas flares from a white dwarf binary star system have been detected for the first time by Oxford University scientists.

Classifying NGC 4861 In Canes Venatici

The lesser-known constellation of Canes Venatici (The Hunting Dogs), is home to a variety of deep-sky objects -- including this beautiful galaxy, known as NGC 4861. Astronomers are still debating on how to classify it.

Astronomers have discovered a cosmic one-two punch unlike any ever seen before. Two of the most powerful phenomena in the Universe, a supermassive black hole, and the collision of giant galaxy clusters, have combined to create a stupendous cosmic particle accelerator.

Two stars are predicted to merge and explode in 2022 producing a bright star visible to the unaided eye.

The constellation of Virgo (The Virgin) is especially rich in galaxies, due in part to the presence of a massive and gravitationally-bound collection of over 1300 galaxies called the Virgo Cluster.

Almost 25,000 light-years away, two dead stars, each more massive than our Sun, but only 20 kilometers in diameter, orbit one another in less than five hours.

Hubble Looks At Spiral Galaxy NGC 3274

Spiral galaxy NGC 3274 is a relatively faint galaxy located over 20 million light-years away in the constellation of Leo (The Lion).

A Stellar Circle of Life

A snapshot of the stellar life cycle has been captured in a new portrait from NASA's Chandra X-ray Observatory and the Smithsonian's Submillimeter Array (SMA).

Galaxies formed and grew billions of years ago by accumulating gas from their surroundings, or colliding and merging with other young galaxies.

The birth of massive stars is still a mystery to us.

Never before have astrophysicists measured light of such high energy from a celestial object so far away. Around 7 billion years ago, a huge explosion occurred at the black hole in the center of a galaxy.

Cosmic Horseshoe Is Not The Lucky Beacon

Although the universe started out with a bang it quickly evolved to a relatively cool, dark place. After a few hundred thousand years the lights came back on and scientists are still trying to figure out why.

This image, taken by the NASA/ESA Hubble Space Telescope's Wide Field Planetary Camera 2, shows a spiral galaxy named NGC 278.

Our Milky Way has a densely populated centre -- a feature common to many galaxies, but unique in that it is close enough to study in depth.

Planetary Nebula With Spiral Arms

The two spiral arms winding towards the bright centre might deceive you into thinking you are looking at a galaxy a bit like our Milky Way.

Why the universe is dominated by matter today, instead of being comprised of equal parts matter and antimatter, is one of the most intriguing questions in all of science.

An experiment to explore the aftermath of cosmic dawn, when stars and galaxies first lit up the universe, has received nearly $10 million in funding from the National Science Foundation to expand its detector array in South Africa.

Quasars are supermassive black holes that sit at the center of enormous galaxies, accreting matter.
