While astrophysicists previously believed that only supernovae could generate long gamma-ray bursts (GRBs), a 2021 observation uncovered evidence that compact-object mergers also can generate the phenomenon. Now, a new simulation confirms and explains this finding. If the accretion disk around the black hole is massive, it launches a jet that lasts several seconds, matching the description of a long GRB from a merger.
Images from the Solar Orbiter revealed small “picoflare” jets within a coronal hole on the Sun, which might supply energy to the solar wind, enhancing...
A new research study explores finite-range interactions for creating quantum entanglement. Metrological institutions around the world administer our time, using atomic clocks based on the...
With a remarkable observational campaign that involved 12 telescopes both on the ground and in space, including three European Southern Observatory (ESO) facilities, astronomers have uncovered the strange behavior of a pulsar, a super-fast-spinning dead star. This mysterious object is known to switch between two brightness modes almost constantly, something that until now has been an enigma. But astronomers have now found that sudden ejections of matter from the pulsar over very short periods are responsible for the peculiar switches.
