A new study analyzing historical photographs taken by the Palomar Observatory between 1949 and 1957 has detected several mysterious bright spots in the sky. These transient objects, captured on film before the first satellites were ever launched, appear to have occurred on dates that strongly correlated with nuclear weapons tests.

Today’s computers store information in magnetic hard drives, keeping files safe even when the device is powered off. But to run programs and process information, computers rely on electricity. Each calculation requires a transfer of information between the electric and magnetic systems. This back-and-forth is a major bottleneck in the speed of modern computing.

Topological insulators could form the basis for revolutionary electronic components. However, as they generally only function at very low temperatures, their practical application has been severely limited to date. Researchers at the University of Würzburg have now developed a topological insulator that also works at higher temperatures. Their results are published in Science Advances.

Small and unassuming, Segue 1 is a nearby dwarf galaxy containing only a handful of stars—too few to provide the gravity needed to keep itself from scattering into space. Like other dwarf galaxies, it was long believed that gravity from a mysterious substance called dark matter was the main binding force.

Precise metrology forms a fundamental basis for advanced science and technology, including bioimaging, semiconductor defects diagnostics, and space telescope observations. However, the sensor technologies used in metrology have so far faced a physical barrier known as the standard quantum limit.

An international team of researchers led by the Leibniz Institute for Astrophysics Potsdam (AIP) has shed light on a decades-long debate about why galaxies spin faster than expected—and whether this behavior is caused by invisible dark matter or by a collapse of gravity on cosmic scales.

In November 1572, a brilliant new star appeared in the constellation Cassiopeia, shining so brightly that it was visible during the day. Danish astronomer Tycho Brahe carefully documented this celestial phenomenon, and the supernova remnant that bears his name has been studied intensively ever since. Now, a new analysis of recent observations suggests that Tycho’s […]

How can artificial intelligence (AI) help astronomers identify celestial objects in the night sky? This is what a recent study published in Nature Astronomy hopes to address as an international team of researchers investigated the potential for using AI to conduct astrophysical surveys of celestial events, including black holes consuming stars or even exploding stars […]
Using the MeerKAT telescope, an international team of astronomers have detected 30 new radio transient pulsars as part of the Meer(more) TRAnsients and Pulsars (MeerTRAP) project. The discovery was reported in a paper published Oct. 20 on the arXiv pre-print server.
