Using the High Energy Stereoscopic System (HESS), German astronomers have investigated a very-high-energy (VHE) gamma-ray source known as HESS J1809−193. Results of the study, published January 18 on the arXiv preprint ...
Researchers using MeerKAT in South Africa have discovered nine millisecond pulsars, most of them in rare and sometimes unusual binary systems, as the first result of a targeted survey. An international team with significant ...

An international team of astronomers has performed a comprehensive, multiwavelength study of a blazar known as 1ES 1218+304. Results of the research, presented in a paper published January 3 on the arXiv preprint server, ...
Using NASA's Fermi spacecraft, Chinese astronomers have investigated the variability and spectral behavior of gamma-ray flares in a distant blazar known as 3C 279. Results of the study, presented in a paper published in the ...
For nearly two decades, astrophysicists have believed that long gamma-ray bursts (GRBs) resulted solely from the collapse of massive stars. Now, a new study upends that long-established and long-accepted belief.

An international team of astronomers has performed a long-term multiwavelength study of a distant gamma-ray emitting blazar known as 1ES 0647+250. Results of the research, published November 23 on arXiv.org, yield important ...
Earlier this year, astronomers were keeping tabs on data from the Zwicky Transient Facility, an all-sky survey based at the Palomar Observatory in California, when they detected an extraordinary flash in a part of the sky ...

Using NASA's Fermi space telescope, Chinese astronomers have investigated a newly discovered millisecond pulsar known as PSR J1835−3259B. As a result, they identified gamma-ray pulsations from this source. The finding is ...
According to a new NASA laboratory experiment, rovers may have to dig about 6.6 feet (two meters) or more under the Martian surface to find signs of ancient life because ionizing radiation from space degrades small molecules ...
