The lifetime of nitrous oxide is decreasing more quickly than expected, which is changing climate projections. Scientists at the University of California, Irvine report that climate change is accelerating the breakdown of nitrous oxide in the atmosphere. This gas is مزید پڑھیں
Astronomers have uncovered an extraordinarily ancient star that offers a rare glimpse into the universe’s earliest chapters. An international team of astronomers has identified the most chemically pristine star ever observed, named SDSS J0715-7334, using data from the Sloan Digital مزید پڑھیں
A new analysis of meteorite isotopes challenges long-held ideas about Earth’s origins, suggesting our planet may have formed almost entirely from nearby material rather than distant sources. Planetary scientists have long debated the origin of the material that formed Earth. مزید پڑھیں
Four astronauts blasted off from Florida on Wednesday on Nasa’s Artemis II mission, a high-stakes voyage around the moon that marks the United States’ boldest step yet toward returning humans to the lunar surface later this decade in a race مزید پڑھیں
By applying machine learning to vast TESS datasets, researchers have built one of the most precise catalogs of nearby exoplanets to date. Astronomers at the University of Warwick have confirmed more than 100 exoplanets, including 31 newly identified worlds, using مزید پڑھیں
A new study proposes an innovative way to uncover elusive supermassive black hole binaries by tracking subtle, repeating flashes of starlight. Researchers from Oxford University and the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) have outlined a new مزید پڑھیں
A mysterious bow shock around the white dwarf RXJ0528+2838 is challenging astronomers’ understanding of how dead stars interact with their surroundings. Gas and dust streaming away from stars can sometimes collide with surrounding material and produce shock waves. Astronomers using مزید پڑھیں
New research suggests our Sun was part of a huge migration of Sun-like stars that moved away from the Milky Way’s center billions of years ago. Scientists have found new evidence that our Sun may have been part of a مزید پڑھیں
Observations show the universe appears flat, yet its true size and global shape beyond the observable horizon may remain forever unknown. The surface of Earth has a measurable size. Scientists can calculate its total area, and if the planet were مزید پڑھیں
Regional wind patterns on Venus may stabilize mountain temperatures while generating dust storms that future landers must withstand. For decades, the surface of Venus has remained one of the least understood environments in the solar system. With only a handful مزید پڑھیں
