Astronomers have made a series of landmark observations of one of the universe’s most violent events. Using the U.S. National Science Foundation Very Large Array (NSF VLA) radio telescope, which is operated by the U.S. National Science Foundation National Radio Astronomy Observatory (NSF NRAO), the team detected polarized light from a gamma-ray burst (GRB) afterglow […]
Astronomers are closer to solving the mystery of how supermassive black holes feed themselves thanks to new images from the James Webb Space Telescope, or JWST. The images provide the clearest view ever seen of gaseous filaments connecting a galaxy’s hot atmosphere to the rotating disk of gas that feeds its central supermassive black hole. […]
A technique for judging whether a common mineral formed through biological activity could aid the search for ancient life on Earth and Mars. Apatite is a ubiquitous phosphate mineral found in terrestrial and extraterrestrial environments. It is a major component of teeth and bones, but it also occurs in igneous rocks and sedimentary phosphorites.

There are parts of the universe that are extremely hard to see, even for our most advanced telescopes. Gas and dust don’t emit light and are visible only by the light they block from stars and galaxies. Magnetic fields are even harder to detect because ordinary light typically passes right through them. However, according to […]
This summer, Subaru Telescope will welcome a new near-infrared spectrograph, NINJA, for its first on-sky engineering observations. NINJA is a new spectrograph designed for time-critical observations of rapidly evolving cosmic events, such as the electromagnetic counterparts of gravitational-wave sources.

When neutron stars merge, they create a powerful explosion called a kilonova that flings out neutron-rich material, some of which decays into heavy elements through a process called the r-process. Recent observations of kilonovae revealed unexpected signatures that could not be explained by existing models.

The expense of launching cargo into space will plummet over the next few years, with the cost of reaching orbit forecast to more than halve between now and the end of the decade, and fall by around 93% by 2040, according to new Cambridge-led research.

More than a century after Albert Einstein first transformed our understanding of gravity, his general theory of relativity continues to withstand ever more demanding experimental tests. Now, an international team led by Ignazio Ciufolini at the Chinese Academy of Sciences has carried out the most precise measurement yet of one of the theory’s most subtle […]
After decades of analyzing reams of lunar rocks back here on Earth, the canonical view of the moon was that it was anhydrous; that it had extraordinarily little water. That all began to change in 2009 with new data from NASA’s Lunar Crater Observation and Sensing Satellite (LCROSS) and the much-ballyhooed evidence of water ice […]
Researchers at the University of Warwick and the University of Colorado Boulder have directly observed, for the first time, four white dwarfs in binary star systems in our nearby region of space. These stellar binaries are all within 65 light-years of Earth, and one contains the ninth-closest white dwarf to the sun.

Scientists have detected evidence of landslides on Pluto for the first time. A paper published in the journal Icarus reports that images taken by the New Horizons spacecraft during a flyby revealed six large landslides in three impact craters.

The massive globular star cluster Omega Centauri has puzzled astronomers for decades. It should be filled with black holes left behind by exploding stars, yet evidence for them is scarce. Now, astronomers using archival data from NASA’s Hubble Space Telescope and supporting observations from NASA’s James Webb Space Telescope have finally located the first stellar-mass […]
The planets that appear most common in the universe could have a lot of water—but it could be hiding where telescopes can’t detect it, according to a new study led by scientists with the University of Chicago.

A giant mirror to create “sunlight on demand” was just approved by the United States Federal Communications Commission (FCC), despite opposition from astronomers and the public, and real safety concerns.

Sugars are key biomolecules in living organisms, as they form the backbone of DNA and RNA and play a fundamental role in metabolic processes. In theories of the origin of life, sugars are also essential for the synthesis of the first nucleic acids. Despite their importance, one of the major questions in origin-of-life research is […]
