Researchers used supercomputers to create nearly 4 million simulated images depicting the cosmos.

Why is the sky near

Clouds of gas in a distant galaxy are being pushed faster and faster -- at more than 10,000 miles per second -- out among neighboring stars by blasts of radiation from the supermassive black hole at the galaxy's center. It's a discovery that helps illuminate the way active black holes can continuously shape their galaxies by spurring on or snuffing out the development of new stars.

By combining forefront X-ray observations with state-of-the-art supercomputer simulations of the buildup of galaxies over cosmic history, researchers have provided the best modeling to date of the growth of the supermassive black holes found in the centers of galaxies.

As space travel becomes more frequent, a new biomarker tool was developed by an international team of researchers to help improve the growing field of aerospace medicine and the health of astronauts.

Scientists are peering into the past and uncovering new clues about the early universe. Since light takes a long time to travel through space, they are now able to see how galaxies looked billions of years ago. The astronomers have discovered that spiral galaxies were more common in the early universe than previously thought. The scientists found that nearly 30% of galaxies have a spiral structure about 2 billion years after the universe formed. The discovery provides a significant update to the universe's origin story as previously told using data from NASA's Hubble Space Telescope.

The structure and function of the kidneys is altered by space flight, with galactic radiation causing permanent damage that would jeopardise any mission to Mars, according to a new study led by researchers from UCL.

Crater 2, located approximately 380,000 light years from Earth, is one of the largest satellite galaxies of the Milky Way. Extremely cold and with slow-moving stars, Crater 2 has low surface brightness. How this galaxy originated remains unclear. A team of physicists now offers an explanation.

Astronomers have discovered a rare hypervelocity L subdwarf star racing through the Milky Way. More remarkably, this star may be on a trajectory that causes it to leave the Milky Way altogether.

Peering deeply into the cosmos, NASA's James Webb Space Telescope is giving scientists their first detailed glimpse of supernovae from a time when our universe was just a small fraction of its current age. A team using Webb data has identified 10 times more supernovae in the early universe than were previously known. A few of the newfound exploding stars are the most distant examples of their type, including those used to measure the universe's expansion rate.

Astronomers have used new data from NASA's Hubble Space Telescope and the retired SOFIA (Stratospheric Observatory for Infrared Astronomy) as well as archival data from other missions to revisit one of the strangest binary star systems in our galaxy -- 40 years after it burst onto the scene as a bright and long-lived nova. A nova is a star that suddenly increases its brightness tremendously and then fades away to its former obscurity, usually in a few months or years.

Astronomers have captured what appears to be a snapshot of a massive collision of giant asteroids in Beta Pictoris, a neighboring star system known for its early age and tumultuous planet-forming activity.

Astrophysicists calculate the likelihood that Earth was exposed to cold, harsh interstellar clouds, a phenomenon not previously considered in geologic climate models.

An international team of planetary scientists has detected patches of water frost sitting atop the Tharsis volcanoes on Mars, which are not only the tallest volcanic mountains on the Red Planet but in the entire solar system.

Astronomers have deciphered the formation history of young star clusters, some of which we can see with the naked eye at night. The team reports that most nearby young star clusters belong to only three families, which originate from very massive star-forming regions. This research also provides new insights into the effects of supernovae (violent explosions at the end of the life of very massive stars) on the formation of giant gas structures in galaxies like our Milky Way.

Astronomers observing exoplanet GJ 3470 b saw evidence of water, carbon dioxide, methane and sulfur dioxide. Astronomers hope the discovery of this exoplanet's sulfurous atmosphere will advance our understanding of how planets forms.
