Magnetars are neutron stars with ultra-strong magnetic fields that are about a quadrillion times greater than the magnetic field of Earth. These huge magnetic...
In new research, astronomers used NASA’s IXPE (Imaging X-ray Polarimetry Explorer) to observe a highly relativistic jet emanating from the blazar BL...
In general relativity, a gravitational white hole is a hypothetical region of space that cannot be entered from outside. It is the reverse of a black hole...
How lightning is started in thunderstorms is poorly known. With a newly-developed 3D mapping and polarization system, physicists at Los Alamos National...
Bright, twisted light can be produced thanks to nanostructured filaments with twisted geometry, according to scientists at the University of Michigan.
Planck’s...
Messier 77 is a well-known, relatively nearby, bright spiral galaxy with a supermassive black hole at its center.
An artist’s concept of Messier 77,...
Cygnus X-3, an X-ray binary system located some 7,400 parsecs (24,136 light-years) in the constellation of Cygnus, represents a class of ultra-luminous...
Astronomers using CSIRO’s Parkes radio telescope (Murriyang) have detected unusual radio signals from XTE J1810-197, a radio magnetar (ultra-magnetic...
A team of physicists led by Dr. Yuan Lu from the Université de Lorraine’s Institut Jean Lamour has used electrical pulses to manipulate magnetic information...
According to astronomers’ best models of black hole evolution, the magnetic fields in the accretion disk need to be strong enough to push the accreting...
Scientists at Aalto University have proposed a three-dimensional metamaterial with an isotropic effect in the visible spectral range.
The new metamaterial...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have captured a high-resolution image of HL Tauri, a young star in the constellation...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have detected linearly polarized thermal emission from dust grains in 9io9, a...
Fast radio bursts (FRBs) are brief flashes of radio waves from distant galaxies that are probably emitted by neutron stars. Some FRBs repeat, which enables...
Centaurus A is located 13 million light-years away in the constellation of Centaurus, and represents the fifth brightest galaxy in the sky.
This composite...
Located 6,500 light-years away in the constellation of Taurus, the Crab Nebula and its pulsar formed in a supernova whose light reached Earth in July 1054.
This...
The newly-observed stellar explosion, named AT2018cow, occurred approximately 180 million light-years away from Earth and belongs to a special class called...
