Astronomers from Germany and France have investigated a newly discovered variable X-ray source known as 3XMM J000511.8+634018. Results of the new study suggest that the source is a polar. The finding is detailed in a paper ...
Chinese astronomers have conducted a gamma-ray and optical variability analysis of the blazar 3FGL J0449.4-4350. The new research, presented in a paper published March 25 on arXiv.org, reports the detection of possible quasi-periodic ...
You know how you leave space in a water bottle before you pop it in the freezer—to accommodate the fact that water expands as it freezes? Most metal parts in airplanes face the more common opposite problem. At high altitudes ...
