A group led by scientists from the RIKEN Cluster for Pioneering Research, using coordinated observations of the Crab pulsar in a number of frequencies, have…
Certain ultralight bosons would be expected to put the brakes on black holes, but new results show no such slowdown. Ultralight bosons are hypothetical particles…
Oxygen in the atmosphere may not be an entirely reliable ‘biosignature,’ but there are ways to distinguish false positives from signs of life, scientists say….
In the southern sky, situated about 4,300 light years from Earth, lies RCW 120, an enormous glowing cloud of gas and dust. This cloud, known…
In April 2019, scientists released the first image of a black hole in galaxy M87 using the Event Horizon Telescope (EHT). However, that remarkable achievement…
There are a lot of things that pose a threat to our planet – climate change, natural disasters, and solar flares, for example. But one…
Every year, our planet encounters dust from comets and asteroids. These interplanetary dust particles pass through our atmosphere and give rise to shooting stars. Some…
Auroral displays continue to intrigue scientists, whether the bright lights shine over Earth or over another planet. The lights hold clues to the makeup of…
In the recent past, space missions dedicated to the study of astrophysical signals in the high-energy spectrum revealed a series of enigmatic excesses not predicted…
For only the second time, astronomers have linked an elusive particle called a high-energy neutrino to an object outside our galaxy. Using ground- and space-based…
To confirm life on other planets, we need to detect far more molecules in their atmospheres than we currently do to rule out non-biological chemical…
In Search for Dark Matter, New Fountain Design Could Become Wellspring of Answers You can’t see it. You can’t feel it. But the substance scientists…
Astronomers have painted their best picture yet of an RV Tauri variable, a rare type of stellar binary where two stars – one approaching the…
Astronomers at Western University have discovered the most rapidly rotating brown dwarfs known. They found three brown dwarfs that each complete a full rotation roughly…
A global science collaboration using data from NASA’s Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station has discovered X-ray surges accompanying…
Magnetic reconnection refers to the reconfiguration of magnetic field geometry. It plays an elemental role in the rapid release of magnetic energy and its conversion…
Looking at the night sky, one’s thoughts might be drawn to astrochemistry. What molecules inhabit the vast spaces between the stars? Would we see the…
A paper by the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) Director Ooguri Hirosi and Project Researcher Matthew Dodelson on…
