The Cosmic Confusion of the Microwave Background in the Search for B-Mode Polarization
Roughly 380,000 years after the big bang, about 13.7 billion years ago, matter (mostly hydrogen) cooled enough for neutral atoms to form, and light was…

Echoes in gravitational wave signals suggest that a black hole’s event horizon may be more complicated than scientists presently believe. The first tentative detection of…
A study by the University of Bonn simulates a universe in which Newton’s laws are only valid to a limited extent. For the first time,…
Allen Lawrence, wrapping up a long career as an electrical engineer, was serious about moving his astronomy hobby beyond the 20-inch (51-centimeter) telescope he’d hauled…
XMM-2599 lived fast and died young, says University of California, Riverside-led international team. An international team of astronomers led by scientists at the University of…
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner, have spotted a peculiar gas cloud that resulted from a confrontation…
The origin of how the Universe created its voids and filaments can now be studied within seconds after researchers developed an artificial intelligence tool called…
New evidence shows that the key assumption made in the discovery of dark energy is in error. High precision age dating of supernova host galaxies…
With ‘Zee burst,’ physicists propose new resonance beyond the standard model. Physicists at Washington University in St. Louis have proposed a way to use data…
Having studied quark-gluon plasma since the late 1970s, Dr. Johann Rafelski summarizes the evolution in our understanding of the exotic quark signature of this primordial…
Preeminent telescope to play critical role in better understanding sun, space weather. Just released first images from the National Science Foundation’s Daniel K. Inouye Solar…
Astronomers witness “frame-dragging” — the dragging of space-time in stellar cosmic dance. An international team of astrophysicists led by Australian Prof Matthew Bailes from OzGrav…
Working together with space researchers, Finnish amateur photographers have discovered a new auroral form. Named ‘dunes’ by the hobbyists, the phenomenon is believed to be…
Matching up maps of matter and light from the Dark Energy Survey and Fermi Gamma-ray Space Telescope may help astrophysicists understand what causes a faint…
Experiment on Beta-Decay Sheds Light on Fate of Intermediate-Mass Stars A group of scientists, among them several from GSI Helmholtzzentrum für Schwerionenforschung and from the…
Archival Data Reveals Earliest Stages of a Dramatic Event Astronomers searching archival data from NASA’s Kepler exoplanet hunting mission identified a previously unknown dwarf nova…
In the scorching atmosphere of exoplanet KELT-9b, even molecules are torn to shreds. Massive gas giants called “hot Jupiters” — planets that orbit too close…
Large Amounts of Oxygen Detected in Ancient Star’s Atmosphere An international team of astronomers from the University of California San Diego, the Instituto de Astrofísica…
