Niels Bohr, a Danish Physicist said “Everything we call real is made of things that cannot be regarded .” Is what we see perceived to be real or is it an illusion?

In the world of our mind’s eye, light travels in a straight line....

The universe is expanding, and that expansion is accelerating. We don’t know what’s causing that acceleration, but that hasn’t stopped us from giving it a name. We call this unknown influence dark energy. The observed acceleration is,...

What if there is no such thing as dark matter? What if our understanding of gravity is just wrong? New work is taking another shot at that Einstein guy. Let’s see if we’ve finally scored a hit with Modified Newtonian Dynamics aka MOND.

The universe that we know, with its luminous stars and orbiting planets, is largely made up of elements we can't actually see -- like dark energy and dark matter -- and therefore don't fully understand. Theoretical physicist Chanda...

The universe gets a little weirder, and more dangerous, every time we study it. Understanding space weather, which can mess with our communications systems, will take strategic planning to monitor.

The satellite launched in February, but in March, it malfunctioned, spun out of control, and broke into pieces. The mission was declared a failure. But! Before it failed, Hitomi managed a couple days' worth of observations.

Gravitational lensing has given us a look at a galaxy in the very, very distant cosmic past using x-ray light, and NASA finally got its ICON mission off the ground!

For years, astronomers have been unable to find up to half of the baryonic matter in the universe. We may just have solved this problem.

How can scientists possibly know the age of the universe? Well, through a variety of factors, including redshift, the CMBR and more.

The universe is microwaving itself. A mystery signal discovered in the 1960s led to a Nobel prize. In this video, Dianna explores one of the most mysterious discoveries in physics - a constant microwave signal that seemed to be coming...

Every year, NASA's Goddard Space Flight Center in Greenbelt, Maryland, recruits hundreds of interns to spend the summer working on revolutionary missions featuring state-of-the-art technology. Maddy Lambert is a student...

Astrum shows what a supervoid really is, and explains why this image isn't one.
