Detailed Record Of Mysterious Fast Radio Burst Found

Fast Radio Bursts (FRBs), brief yet brilliant eruptions of cosmic radio waves, have baffled astronomers since they were first reported nearly a decade ago. Though they appear to come from the distant Universe, none of these enigmatic events has revealed more than the slimmest details about how and where it formed, until now. By poring […]

Cool, Dim Dwarf Star Is Magnetic Powerhouse

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered that a dim, cool dwarf star is generating a surprisingly powerful magnetic field, one that rivals the most intense magnetic regions of our own Sun. The star’s extraordinary magnetic field is potentially associated with a constant flurry of solar-flare-like eruptions. As with our Sun, these […]

Dark Matter Dominates In Nearby Dwarf Galaxy

Dark matter is called “dark” for a good reason. Although they outnumber particles of regular matter by more than a factor of 10, particles of dark matter are elusive. Their existence is inferred by their gravitational influence in galaxies, but no one has ever directly observed signals from dark matter. Now, by measuring the mass […]

Astronomers Stunned To Find ‘Hot Jupiter’ With Companions

During the past two decades, astronomers have discovered 300 “hot Jupiters,” but for the first time they’ve found one that has two close-in planetary companions. Scientists made the startling discovery using data collected by the K2 mission, an extension of the Kepler space telescope mission. Says Juliette Becker, a graduate student in astronomy at the […]

Explainer: What Is A Neutron Star?

Neutron stars are arguably the most exotic objects in the universe. Like one of those annoying friends who seemingly must overachieve in every aspect of life, neutron stars exceed in almost every category: surface gravity; magnetic field strength; density; and temperature. “But wait,” I hear you say, “black holes are much denser!” In one sense […]
