In order to illuminate the darkness we turn to the light. Whether the sun, a lamp, or a candle, we rely on electromagnetic radiation to reveal the world, and indeed the Universe, around us.

Ancient Starlight Recorded By Dark Energy Camera

For the first time, scientists have detected part of the invisible dark matter skeleton of the universe, where over half of all matter is believed to reside.

Researchers Make Celestial Observation, Despite Astronomical Odds

Astronomers were able to beat the odds by observing gravitational lensing taking place at 10 billion light-years away from Earth.

Astronomers Find Cosmic Lenses With Feeding Black Holes

In space, it sometimes happens that two galaxies are aligned in just the right way that the closer galaxy distorts and magnifies the appearance of the one behind it. For astronomers, finding these alignments is like coming across giant, cosmic magnifying glasses.

The discovery of a dark matter mass left behind after what is being called a wreck between massive clusters of galaxies has experts questioning current theories regarding the invisible substance believed to make up more than 80% of the universe.

Hubble Zooms In On Magnified Galaxy

The Bullet Cluster is made up of two colliding clusters galaxies. According to a 2006 study, the Bullet Cluster also shows the best evidence for the existence of Dark Matter. From observations of galaxy cluster collisions it has been found that many show displacement between their center of visible matter and their gravitational potential. Each component, stars, gas, and dark matter, within a cluster pair behaves differently during a collision allowing for each to be studied separately....

Gravitational Lens -- A gravitational lens is formed when the light from a very distant, bright object (such as a quasar) is "bent" around a massive object (such as a massive galaxy) between the bright object and the viewer. The process is known as gravitational lensing, and was one of the predictions made by Einstein's general relativity. Description In a gravitational lens, the gravity from the massive object bends light as a lens might. As a result, the path of the light from a...
