The impact crater is the second discovered in China.
A crescent-shaped crater in Northeast China holds the record as the largest impact crater on Earth that formed in the last 100,000 years.
Prior to 2020, the only other impact crater ever discovered in China was found in Xiuyan county of the coastal province of Liaoning, according to a statement from the NASA Earth Observatory. Then, in July 2021, scientists confirmed that a geological structure in the Lesser Xing’an mountain range had formed as a result of a space rock striking Earth. The team published a description of the newfound impact crater that month in the journal Meteoritics and Planetary Science.
Researchers at the Northwestern University and Weinberg College of Arts and Sciences may have potentially come across a kilonova afterglow, the first of its kind ever to be observed, according to a university press release.
A kilonova is the merger of two neutron stars that creates a blast 1,000 times brighter than a classical nova. On August 17, 2017, astronomers observed the first-ever neutron star merger, GW170817, using light as well as gravitational waves. Ever since researchers across the globe have been pointing ground and space telescopes towards this event to study it across the electromagnetic spectrum.
