Using ESA's XMM-Newton space telescope, astronomers have spotted bright X-ray outbursts emitted by a Be/X-ray binary known as A0538−66. The discovery marks the ending of an over three-decade-long period of quiescence of ...
Observations made with a new instrument developed for use at the 2.1-meter (84-inch) telescope at the National Science Foundation's Kitt Peak National Observatory have led to the discovery of the fastest eclipsing white dwarf ...

A team of researchers from the U.S., Denmark and the U.K., working with a group at NASA's Ames Research Center, has found a binary star system that dims unpredictably. They have written a paper describing their findings and ...
An international team of astronomers reports the detection of gamma-ray pulsations from the millisecond pulsar (MSP) known as PSR J0952−0607. The finding, available in a paper published May 27 on arXiv.org, sheds more light ...
Using the Devasthal optical telescope in India, astronomers have conducted photometric observations of the globular cluster NGC 4147. The observational campaign yielded the discovery of 28 new variable stars in this cluster. ...
Scientists have found evidence that pairs of stars have been kicked out of their host galaxies. This discovery, made using data from NASA's Chandra X-ray Observatory, is one of the clearest examples of stellar pairs being ...

By analyzing data from NASA's Rossi X-ray Timing Explorer (RXTE) satellite, astronomers have detected millihertz quasi-periodic oscillations from a low-mass neutron star X-ray binary designated EXO 0748−676. The finding ...
By combining transit photometry, radial velocity observations, and asteroseismology, astronomers have gathered important information about the properties of a highly eccentric, eclipsing binary system known as KOI-3890. The ...
Books can burn. Computers get hacked. DVDs degrade. Technologies to store information—ink on paper, computers, CDs and DVDs, and even DNA—continue to improve. And yet, threats as simple as water and as complex as cyber-attacks ...
