Using data from the Rossi X-ray Timing Explorer (RXTE) satellite, astronomers from the Florida Institute of Technology have discovered a quasi-periodic oscillation (QPO) in the galaxy NGC 4945. The finding, reported in a ...
An international team of astronomers reports the discovery of an unusual Type II supernova in the galaxy NGC 1068, as part of the DLT40 survey. The newly detected event, designated SN 2018ivc, exhibits rapidly changing light ...
New research presented by an international team of astronomers suggests that a recently detected transient, designated HSC16aay, is a Type IIn supernova. A research paper reporting the discovery and detailing the finding, ...
Astronomers have carried out a study of almost 300 hundred planetary nebulae in the supergiant elliptical galaxy Messier 87. The new research, published September 27 on the arXiv pre-print repository, reveals essential information ...
Lenses appear in all sorts of everyday objects, from prescription eyeglasses to cell-phone cameras. Typically, lenses rely on a curved shape to bend and focus light. But in the tight spaces inside consumer electronics and ...
