A pulsar wind nebula is created when the powerful magnetic field of a rapidly spinning neutron star accelerates surrounding charged particles to nearly...
Radio-emitting neutron stars are objects with spin periods ranging from milliseconds to tens of seconds; as they age and spin more slowly, their radio...
A micronova is a thermonuclear blast that happens on the surface of certain stars and lasts for just a few hours making them extremely difficult to observe.
This...
The significantly weaker magnetic field, smaller magnetosphere, and much faster timescale of processes around Mercury, when compared with Earth, enable...
Saturn is unique among planets observed to date in that some of its aurorae are generated by swirling winds within its atmosphere, and not just from the...
The new image from the MeerKAT telescope at the South African Radio Astronomy Observatory (SARAO) in Cape Town, South Africa, shows nearly 1,000 magnetized...
Dr. Chengcai Shen from the Harvard & Smithsonian Center for Astrophysics and colleagues have analyzed images of the so-called supra-arcade downflows...
Astronomers using the Murchison Widefield Array (MWA) telescope have discovered a spinning object that pulses every 18.18 minutes; they’ve localized...
The giant gamma-ray flare event, designated GRB 2001415, was emitted by a powerful magnetar in NGC 253, an active starburst galaxy approximately 11 million...
Using ultraviolet data from the NASA/ESA Hubble Space Telescope, astronomers have detected carbon ions — charged particles that interact with magnetic...
A rare upper-atmosphere phenomenon called Strong Thermal Emission Velocity Enhancement (STEVE) has been well documented by amateur aurora watchers from...
Astronomers using NSF’s Karl G. Jansky Very Large Array have captured unprecedented high-fidelity radio images of a jet of material propelled from the...
A white dwarf in the binary system LAMOST J024048.51+195226.9 (J0240+1952 for short) completes a full rotation once every 24.93 seconds, making it the...
Around 4.567 billion years ago, our Solar System harbored a gap within the protoplanetary disk, near the location where the main asteroid belt resides...
The North Polar Spur and the Fan Region are two bright, large-scale radio structures that are seen on opposite sides of the sky. According to new research,...
Astronomers using the Low Frequency Array (LOFAR), a large radio telescope network located mainly in the Netherlands, have detected coherent low-frequency...
New research shows that the magnetic field of our planet was relatively weak (less than half the strength of the long-term average field) for tens of millions...
