SGR 1935+2154, emitted a pair of luminous radio bursts on 28 April 2020. There was speculation that these may be galactic examples of fast radio bursts. Swift J1818.0-1607, X-ray burst detected March 2020, is one of five known magnetars that are also radio pulsars. By its time of discovery, it may be only 240 years old.
At 15:44:06 UT on 7 Mar 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230307A . [6] at the same time, the Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor light curve shows a roughly fast rise and exponential decay (FRED) shape with a possible precursor, with a total duration of ~100 sec. [7] At 2023-03-07T15:44:09Z UT (Solar Orbiter onboard ...
A fast radio burst, ... astronomers to trace FRB 20240209A to a region of space associated with an 11.3-billion-year-old galaxy that no longer forms stars. ... FRB to be found outside a dead ...
The magnetosphere of Jupiter is the cavity created in the solar wind by Jupiter's magnetic field.Extending up to seven million kilometers in the Sun's direction and almost to the orbit of Saturn in the opposite direction, Jupiter's magnetosphere is the largest and most powerful of any planetary magnetosphere in the Solar System, and by volume the largest known continuous structure in the Solar ...
The Earth has been hit by a powerful blast of energy from the very depths of the universe. The fast radio burst is the most distant of its kind of ever seen, coming from so far away that it has ...
Scorpius X-1 is some 9,000 ly from Earth and after the Sun is the strongest X-ray source in the sky at energies below 20 keV. Its X-ray output is 2.3 × 10 31 W, about 60,000 times the total luminosity of the Sun. [11] Scorpius X-1 itself is a neutron star.
About two billion years ago in a galaxy far beyond our Milky Way, a big star met its demise in a massive explosion called a supernova that unleashed a huge burst of gamma rays, which pack the most ...
The burst saturated the Fermi Gamma-ray Space Telescope's detector, [17] which captured gamma ray photons with energies exceeding 100 GeV. [18] GRB 221009A is by far the most productive event for very high-energy photons ever witnessed by scientific instrumentation.
