The cosmic optical background is an important observable that constrains energy production in stars and more exotic physical processes in the universe, and provides a crucial cosmological benchmark ...

Ultra-deep images, such as this one from Hubble, still have fundamental limitations. We cannot be certain we've identified all of the faint, small, diffuse objects in this field of view. From its ...

Images taken by NASA’s New Horizons mission on its way to Pluto, and now the Kuiper Belt, have given scientists an unexpected tool for measuring the brightness of all the galaxies in the universe, ...

Scientists have traveled to the edges of the solar system, virtually, at least, to capture the most accurate measurements to date of the faint glow that permeates the universe—a phenomenon known as ...

It is a questions that has baffled the internet – is the background of an animated image black or is it white? An optical illusion has surfaced that shows a cluster of spinning crosses, leaving many ...

Images taken by NASA's New Horizons mission on its way to Pluto, and now the Kuiper Belt, have given scientists an unexpected tool for measuring the brightness of all the galaxies in the universe.

Scientists have taken a virtual trip to the far reaches of our solar system to measure the faint glow that fills the universe, called the cosmic optical background. This glow is the dim light left ...

Artist’s concept of the New Horizons spacecraft as it approaches Pluto and its largest moon, Charon, in July 2015. NASA How much light in the night sky comes from galaxies beyond the Milky Way?

And according to the people who found it, the phenomenon has never been previously reported. Japanese cognition and illusion researcher Kohske Takahashi provided an extensive scientific breakdown and ...

Since the invention of optical tweezers, optical manipulation has advanced significantly in scientific areas such as atomic physics, optics and biological science. Especially in the past decade, ...

Anyone who has used a standard fluorescence microscope has faced a familiar problem: when an object goes out of focus, its image becomes blurred but does not disappear. This simple problem presents a ...
