A brand-new radio signal from deep space is once again challenging our understanding of these mysterious phenomena. Not only is this brand-new fast radio burst, called FRB 20191221A, another extremely rare repeater, but it is not even that quick: the radio flashes received across intergalactic space are three seconds in duration, concerning 1,000 times longer […]

Far out in the Milky Way, about 22,000 light-years from Earth, a star unlike any other roars with a magnetic power that beats anything physicists have seen before. At an enormous 1.6 billion Tesla, a pulsar named Swift J0243.6+6124 smashes the previous records of around one billion Tesla, discovered surrounding the pulsars GRO J1008-57 and

Spirals, ellipticals, and irregulars are all more frequent than ring galaxies. Finally, we know how these ultra-rare things are made. When we look out into deep space, beyond the confines of the Milky Way, we discover that the Universe is not quite so empty. Galaxies-tiny and huge, near and far, in rich clusters and near-total

Amateur astronomers may very soon be able to see a comet initially spotted in 2017. Comet C/2017 K2 (PANSTARRS), abridged as K2 for brief, was once the most distant active comet ever before pinpointed, a difference it recently ceded to the mega comet Bernardinelli-Bernstein, found out last year. However, even without a superlative, K2 is
