The Whirlpool galaxy (M51) is a classic grand spiral galaxy. It was the first object identified as a spiral, way back in 1845. At the time, it and other galaxies were considered spiral nebulae, since […]

Scientists have successfully demonstrated a breakthrough in how sensitive radio telescopes can be used to significantly improve the world’s ability to detect, track and characterize satellites and space debris in orbit.This post was originally published […]

According to current understanding, the universe is expanding—and is doing so at an accelerating rate. This is believed to be caused by something called the cosmological constant, which was first proposed by Albert Einstein in […]

Mysterious high-speed “bullets”—clumps of possibly oxygen-rich gas traveling at up to 20 million miles per hour—have been discovered shooting out of the rarest stellar explosion in our galaxy.This post was originally published on this site

Scientists at the University of California, Riverside, have developed a new way to help gravitational-wave observatories see farther into the universe by solving one of their biggest challenges: tiny heat-induced distortions in the massive mirrors […]

A black hole may be stirring a “pot” of gas containing a neighboring galaxy in the early universe, according to a new study published in Astronomy & Astrophysics that used observations from NASA’s Chandra X-ray […]

For decades, astronomers have cast galaxy mergers as the universe’s ultimate relationship drama: two galaxies collide, chaos erupts, black holes awaken and star formation comes to a screeching halt. Upending this long-held belief, new research […]

The star that formed the Jellyfish nebula may have had a partner star that exploded 100,000 years earlier, according to international researchers, who say that this may be the first known discovery of a binary […]

Stars and galaxies make up much of the universe’s ordinary, observable matter. But for decades, scientists have wrestled with a cosmic conflict: There should be much more.This post was originally published on this site

A new simulation study suggests that the Antarctic 12-m Terahertz Telescope (ATT12), a next-generation facility led by University of Tsukuba, could uncover between 1 and 10 million dusty star-forming galaxies throughout cosmic history.This post was […]
