ESA's Gaia space telescope has further disentangled the history of our galaxy, discovering two surprising streams of stars that formed and wove together more than 12 billion years ago.
Imagine the embers of a campfire, slowly dimming over time. That is the fate most stars in the universe face. After their nuclear fuel is spent, 98 percent of stars—including our sun—will eventually become white dwarfs. ...
Using the Canada France Hawaii Telescope (CFHT), Chinese astronomers have performed multi-band observations of a merging dwarf galaxy known as VCC 322. Results of the observational campaign, presented March 4 on the preprint ...
Astronomers are currently enjoying a fruitful period of discovery, investigating the many mysteries of the early universe. The successful launch of the James Webb Space Telescope (JWST), a successor to NASA's Hubble Space ...
When they are active, supermassive black holes play a crucial role in the way galaxies evolve. Until now, growth was thought to be triggered by the violent collision of two galaxies followed by their merger; however, new ...
It's been a long, eight-day leap week, and this weekend, I'm spending my free time working on the manuscript for my style guide for science writers, "How to Effectively Split an Infinitive."
Using archival data from the Gemini North telescope, a team of astronomers has measured the heaviest pair of supermassive black holes ever found. The merging of two supermassive black holes is a phenomenon that has long been ...
Astronomers have discovered one of the most powerful eruptions from a black hole ever recorded. This mega-explosion billions of years ago may help explain the formation of a striking pattern of star clusters around two massive ...
In a new study, scientists have mapped magnetic fields in galaxy clusters, revealing the impact of galactic mergers on magnetic-field structures and challenging previous assumptions about the efficiency of turbulent dynamo ...
As NASA explores the unknown in air and space, a new mission to survey ultraviolet light across the entire sky will provide the agency with more insight into how galaxies and stars evolve. The space telescope, called UVEX ...
