Water is crucial for life, but how do you make water? Cooking up some H2O takes more than mixing hydrogen and oxygen. It requires the…
The more solar observatories, the merrier: Scientists have developed new models to see how shocks associated with coronal mass ejections, or CMEs, propagate from the…
A merger between galaxies can trigger intense radiation from bursts of star formation and from the accretion of gas onto the two supermassive black holes…
The first dataset from the Hyper Suprime-Cam Subaru Strategic Plan (HSC-SSP) can be seen easily with the “HSC Viewer” on your PC or tablet. The…
Galaxies are not static islands of stars — they are dynamic and ever-changing, constantly on the move through the darkness of the Universe. Sometimes, as…
A new kind of star comes up from a study by SISSA’s postdoctoral researcher Raúl Carballo-Rubio. In a piece of research recently published in Physical…
Capturing images of our home planet from the perspective of faraway spacecraft has become a tradition at NASA, ever since Voyager, 28 years ago, displayed…
Data collected by NASA’s Juno mission to Jupiter indicate that the atmospheric winds of the gas-giant planet run deep into its atmosphere and last longer…
Ordinarily, a supernova marks the death of a mammoth star, which then briefly outshines an entire galaxy before fading away. Not so for a baffling…
New data from the Atacama Large Millimeter/submillimeter Array (ALMA) and other telescopes have been used to create this stunning image showing a web of filaments…
NASA is looking at how the Lunar Orbital Platform-Gateway can create value for both robotic and human exploration in deep space. In late 2017, the…
