Chinese astronomers have used NASA's Fermi gamma-ray space telescope to conduct a long-term study of a bright gamma-ray pulsar known as PSR J0007+7303. In their results, they identified more glitching events in this pulsar. ...
An international team of astronomers has employed NASA's Chandra X-ray observatory to perform the most detailed study of a supergiant star known as Wd1-9, which yielded important insights into the properties and nature of ...
An international team of astronomers reports the discovery of a new long-period radio transient, which received the designation ASKAP J144834−685644 (ASKAP J1448−6856 for short). The newfound transient is a crucial addition ...
A large sub-Neptune-sized planet revolving around a red dwarf star 124 light years away has been the topic of debate among several scientists in recent months.
In 2015, astronomer Tabetha Boyajian and colleagues announced the discovery of unusual light fluctuations coming from a star about 1,500 light-years away. It came to be known as "Tabby's star" or "Boyajian's star," and the ...
Using the Hubble Space Telescope (HST), astronomers have observed a nearby ultra-diffuse galaxy designated F8D1. The new observations, presented July 17 on the pre-print server arXiv, deliver important insights into the star ...
The first black hole images stunned the world in 2019, with headlines announcing evidence of a glowing doughnut-shaped object from the center of galaxy Messier 87 (M87 —55 million light years from Earth. Supercomputer simulations ...
