Polish astronomers have performed photometric observations of a short-period variable star known as NSVS 2983201. They have found that the object is a contact binary system with a mass ratio of about 0.36. The finding was ...
Scientists have simulated, for the first time, the merger of two black holes of vastly different sizes, with one mass 100 times larger than the other. This extreme mass ratio of 100:1 breaks a barrier in the fields of numerical ...

(Phys.org)—Using a gravitational microlensing technique, astronomers have detected a substellar companion of a host star in the system designated MOA-2012-BLG-006L. The new object is assumed to be a high-mass giant planet ...
Hair fiber analysis, a forensic crime tool with a questionable past, could soon have a brighter future thanks to the development of a more refined scientific technique that could reveal much about a person's lifestyle. Scientists ...

Why do two-dimensional exciton-polaritons interact? The exciton-polariton quasiparticle is part light (photon), and part matter (exciton). Their excitonic (matter) part confers them the ability to interact with other particles, ...
