A unique technique allowed astronomers to see the early universe as a "sea of light" and explore the effects of gravity and ...

By analyzing the data from various space observatories and ground-based telescopes, European astronomers have performed a ...

To unlock materials of the future, including better photocatalysts or light-switchable superconductors, researchers need to ...

A newly studied ferroelectric crystal can tune and manipulate ultraviolet and blue light in ways that could transform integrated photonics.

Sir Isaac Newton (1643-1727) was one of the greatest scientists in history whose contribution in the scientific revolution transformed our perception of the universe. Newton was born prematurely in ...

Astronomers have uncovered a hidden cosmic web of galaxies and gas by mapping hydrogen light from the early universe.

Researchers describe the science behind creating lighting to make us all happy and productive indoors. A company is using the technology to create commercial lightbulbs available later this year.

Astronomers with the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX), have used data from the project to make the ...

New 3D map of the early universe from HETDEX reveals faint hydrogen light linking galaxies 9 to 11 billion years ago.

Blue light is a high-energy part of visible light from the sun, screens, and light-emitting diode (LED) bulbs. Your cornea and lens don’t block blue light the way they block ultraviolet (UV) rays.

Intense pulsed light (IPL) therapy, also known as a photo facial, is a way to improve the color and texture of your skin without surgery. It can undo some of the visible damage caused by sun exposure ...
