The universe’s expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously thought, a new study suggests.This post was originally published on this site

Astronomers using W. M. Keck Observatory on Maunakea, Hawaiʻi Island have taken the closest-ever look at the dusty regions where planets form, offering new insight into the earliest stages of planetary birth.This post was originally […]

The sun is governed by a strict rhythm. The magnetic activity of the sun displays a cyclic variation, reaching a maximum approximately every eleven years. Two enormous plasma circulations, each in one solar hemisphere, set […]

As telescopes have become more powerful, it’s turned out our solar system is not the only game in town: There are millions of other planets out there in the galaxy. But we’re still teasing out […]

Aging stars may be destroying the giant planets orbiting closest to them, according to a new study by astronomers at UCL and the University of Warwick.This post was originally published on this site

An international team of researchers has just revealed the existence of three Earth-sized planets in the binary stellar system TOI-2267 located about 190 light-years away. This discovery, published in Astronomy & Astrophysics, is remarkable as […]

The origins of extremely high-energy particles that fill the universe—such as protons, electrons, and neutrinos—remain one of the longest-standing mysteries in modern astrophysics. A leading hypothesis suggests that “explosive transients,” including massive stellar explosions (supernovae) […]

A research team led by the Shanghai Astronomical Observatory of the Chinese Academy of Sciences has used the Tianma Radio Telescope to conduct multi-band radio observations of the returning comet 12P/Pons-Brooks (12P). They measured its […]

Researchers have achieved a breakthrough in solar physics by providing the first direct evidence of small-scale torsional Alfvén waves in the sun’s corona—elusive magnetic waves that scientists have been searching for since the 1940s.This post […]

An international team of astronomers has created the first-ever large-scale maps of a mysterious form of matter, known as CO-dark molecular gas, in one of our Milky Way’s most active star-forming neighborhoods, Cygnus X. Their […]
