Astronomers have confirmed a powerful radio galaxy from nearly 12.5 billion years ago. The source, TXS 2354+015, was originally identified as a high-redshift candidate from its characteristic drop in optical light, and follow-up ...
An international team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), of which the U.S. National Science Foundation National Radio Astronomy Observatory is a partner (NSF NRAO), has combined ...
Physicist Francis Halzen has an impressively long list of academic accolades—but every October, as the Nobel Prize rolled around, his failure to bag the biggest award of them all left him "miserable," he admits.
Astronomers have observed the longest-lasting central engine activity ever recorded from a gamma-ray burst. The burst occurred at a redshift of 0.8577, and the activity lasted about 27 days in the burst's own rest frame—around ...
Evidence for hypernovae, theorized to be the most powerful explosions in the universe, has been disputed in two papers by University College London (UCL) researchers.
The only known supernova remnant of its kind in the Milky Way has an unexpectedly intricate structure: chains of gas knots resembling pearls on a string, each wide enough to fit the solar system multiple times. Using the ...
Earth seems like a troubled place right now, but at least our cosmic surroundings appear peaceful. This is not universally true, as explosions, collisions and other dangers lurk in other places and times.
Francis Halzen won the Nobel Prize in physics on Tuesday for his efforts to demystify a rare group of neutrinos, tiny cosmic particles that scientists believe offer clues to how the universe evolved.
Like Earth, most planetary bodies circle their star in stable, detached orbits. These companionable systems can suddenly change when a planet comes too close to its star. In such a close encounter, a star can pull the planet ...
Dark matter could be a type of matter in the universe that does not emit, absorb or reflect detectable light and appears to interact very weakly with regular matter. Although physicists have observed gravitational effects ...
