100th woman in space, Emily Calandrelli, stands up to ‘small men’ on the internet: ‘I should have expected this.’ (Image Credit: Space.com) Emily Calandrelli made history on Nov. 22, 2024, when she became the 100th woman to go to space. But thanks to “small men on the internet,” the monumental milestone was […]
Examining how Mars’ infamous dust storms can engulf the entire planet (Image Credit: Phys.org) Credit: Pixabay/CC0 Public Domain In a new study, planetary scientists at the University of Colorado Boulder have begun to unravel the factors that kick off major dust storms on Mars—weather events that sometimes engulf the entire planet in […]
More than 10,000 supernovae counted in stellar census (Image Credit: Phys.org) SN 1987a, a Type II supernova remnant first observed in 1987, is visible in this image taken by the Hubble Space Telescope in 2017. The bright ring around the exploded star is material it had ejected approximately 20,000 years before its […]
Black hole debate settled? Stellar-mass black holes found at heart of Milky Way’s largest star cluster (Image Credit: Phys.org) Credit: University of Surrey Could a decades-long debate about the mysterious movements of stars in Omega Centauri, the largest star cluster in the Milky Way, finally be resolved? Omega Centauri is a massive […]
Webb telescope’s largest study of universe expansion confirms challenge to cosmic theory (Image Credit: Phys.org) Credit: CC0 Public Domain New observations from the James Webb Space Telescope suggest that a new feature in the universe—not a flaw in telescope measurements—may be behind the decade-long mystery of why the universe is expanding faster […]

Dense molecular gas and dusty torus detected in the Swelling Spiral galaxy (Image Credit: Phys.org) NGC 4303 rest-frame spectra from 84 to 111 GHz obtained with the Redshift Search Receiver (RSR/LMT). Credit: Soní et al., 2024. Using the Large Millimeter Telescope (LMT) in Mexico, astronomers have performed spectroscopic observations of the Swelling […]
A technosignature that could detect an extraterrestrial civilization’s reliance on nuclear fusion (Image Credit: Phys.org) The time (in millions of years) taken for an exoplanet’s atmosphere to reach an anomalously low deuterium-to-hydrogen ratio, relative to interstellar space around it, given the energy consumption of its advanced civilization (in terawatts), assuming an Earth-like […]
Astronomers discover more dark comets (Image Credit: Phys.org) This artist’s concept shows interstellar object 1I/2017 U1 (‘Oumuamua) after its discovery in 2017. While itself not a dark comet, ‘Oumuamua’s motion through the solar system has helped researchers better understand the nature of the 14 dark comets discovered so far. Credit: European Southern […]
‘Our understanding of the universe may be incomplete’: James Webb Space Telescope data suggests we need a ‘new cosmic feature’ to explain it all (Image Credit: Space.com) New observations from the James Webb Space Telescope (JWST) have corroborated data from its predecessor, the Hubble Space Telescope, to determine something is missing from […]
