Scientists have unveiled a groundbreaking material capable of bending light in such a way that it renders objects invisible.

For the experiment, a high-power green laser was directed through ruby cube and illuminated with a blue laser from the side. The green laser increases the optical absorption of the blue illuminating ...

To establish the overall mood and lighting, add a gradient layer on top of a solid background. This helps to give a sense of depth and atmosphere. You can also add a gradient transparency using layer ...

Oxford University scientists may have solved one of the greatest hindrances of expanding access to solar energy. Scientists from the university’s physics department have created an ultra-thin layer of ...

The speed of light in a vacuum is the absolute speed limit of the universe. As you accelerate towards it, any object with mass suddenly finds it has a lot more of it, and so it takes more and more ...

Here is everything I saw with a smart telescope in a light-polluted city including galaxies, nebulas and star clusters.
