Astronomers report the discovery of a new galactic stellar cluster located some 24,000 light years away. The newfound cluster, which received the designation Barbá 2, turns out to host at least several supergiant stars. ...
Starting with the direct detection of gravitational waves in 2015, scientists have relied on a bit of a kludge: they can only detect those waves that match theoretical predictions, which is rather the opposite way that science ...
Using the TÜBİTAK National Observatory (TUG) and NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have investigated a short-period contact binary known as CC Com. As a result, they detected two additional ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new exoplanet. The newfound alien world, designated TOI-3261b, is nearly the size of Neptune and its equilibrium ...
Astronomers report the discovery of a new galaxy in the constellation Corvus. The newfound galaxy, which received designation Corvus A, has a relatively low mass, is gas-rich and isolated. The discovery was presented in a ...
A crystal is an arrangement of atoms that repeats itself in space, in regular intervals: At every point, the crystal looks exactly the same. In 2012, Nobel Prize winner Frank Wilczek raised the question: Could there also ...

Light is electromagnetic radiation, particularly radiation of a wavelength that is visible to the human eye (about 400–700 nm, or perhaps 380–750 nm.) In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not.
Three primary properties of light are:
Light, which exists in tiny "packets" called photons, exhibits properties of both waves and particles. This property is referred to as the wave–particle duality. The study of light, known as optics, is an important research area in modern physics.
