James Clerk Maxwell FRS FRSE (13 June 1831 – 5 November 1879) was a Scottish physicist and mathematician [1] who was responsible for the classical theory of electromagnetic radiation, which was the first theory to describe electricity, magnetism and light as different manifestations of the same phenomenon.
1894 – Paul Drude introduces the symbol c for speed of light in vacuum. 1895 – Hendrik Lorentz corrects his 1892 model, proposing a contraction by the Lorentz factor (γ). 1895 – Albert Einstein probably makes his thought experiment about chasing a light beam, later relevant to his work on special relativity.

A light-year, alternatively spelled light year (ly or lyr [3]), is a unit of length used to express astronomical distances and is equal to exactly 9 460 730 472 580.8 km, which is approximately 9.46 trillion km or 5.88 trillion mi.
The following is a list of astronomers, astrophysicists and other notable people who have made contributions to the field of astronomy.They may have won major prizes or awards, developed or invented widely used techniques or technologies within astronomy, or are directors of major observatories or heads of space-based telescope projects.
A mysterious radio blast from space detected in 2022 originated in the magnetic field of an ultra-dense neutron star 200 million light years away. Known as fast radio bursts, or FRB, such brief ...
Scientists have discovered a mysterious pulsating light—and they don’t know what it could be. It pulses at a rate of about once every 21 minutes, and has been doing so since at least 1988.
Scientists stand ready to manipulate quantum light, just as Albert Einstein envisioned in 1916. Researchers from the University of Sydney and the University of Basel successfully managed to ...
