Is it my impression or are many things falling from the sky lately?
The residents of the region of Baturité, state of Ceará, were frightened, as they thought that an airplane had crashed on the outskirts of the small town.
According to experts, a weather satellite managed to record the explosion and they are still doing studies to determine the nature of the phenomenon.
Astronomers have watched a star be destroyed by the process of spaghettification, a rare event triggered when a sun strays too close to a black hole.
AT2019qiz was ripped apart by a supermassive black hole in the constellation of Eridanus. Though it is 215 million light years from Earth, it is the closest star we’ve seen annihilated in such a way. The extreme tidal forces exerted on the sun stretched it into long noodle-like strands that were torn apart as it was gobbled up, a violent affair that set off bright flares of electromagnetic energy.
Years after we detected two neutron stars crashing into each other, we’re still picking up X-rays. We don’t know why
After a thousand days of observations, the continuing X-ray radiation from two neutron stars smashing into one another has left astronomers puzzled.
The collision, code-named GW170817, was picked up by our planet’s LIGO and Virgo gravitational wave detectors in mid-2017. The incredible crash, some 130 million light-years away, spilled a heady mix of electromagnetic signals into space as well as the gravitational wave we detected here on Earth.
One remarkable feature of the merger was its kilonova, which immediately followed an initial gamma-ray burst. Light from this kilonova faded about three weeks after GW170817 was observed, as expected. Curiously, though, X-rays were picked up nine days after the merger’s gravitational wave was detected, and they continue to linger well past what’s typically considered normal. The X-ray afterglow is still visible three years after the detection of GW170817.
