Fast Radio Bursts (FRBs) are one of the most powerful and enigmatic astronomical phenomena known. Like gravitational waves (GW) and gamma-ray bursts (GRBs), fast radio…
NASA wants to conquer deep space: its new propulsion system promises to help meet that challenge
The first thing is that the human being returns to the Moon. That is the goal of the Artemis program. Then probably Mars. But at…
Did a phenomenon comparable to a volcanic eruption occur in a magnetar?
SGR 1935+2154, located about 30,000 light-years distant from Earth, is a magnetar, a highly magnetic class of neutron star (a star corpse less dense than…
Ongoing collision between at least three galaxy clusters
Astronomers have captured a spectacular ongoing collision between at least three galaxy clusters, combining NASA’s Chandra Observatory, ESA’s XMM-Newton Observatory, and three radio telescopes. Collisions…
Astrophysicist suggests that aliens have not made contact with Earth because we are not intelligent enough
A new solution to the Fermi Paradox holds that aliens would only be interested in contacting the most technologically advanced planets. Where are the aliens?…

NASA detects the first gamma-ray eclipses in ‘spider’ star systems
Experts classify these disparate binary star systems by the names of spider species whose females sometimes devour their smaller mates. An international team of astronomers…
How massive black holes ‘feed’ on intergalactic gas
Research led by the University of Southampton has revealed how supermassive black holes feed on gas clouds that come from other galaxies hundreds of thousands…
A New Model for Dark Matter
