When we try to make sense of the universe when it was less than a second old, we have no theory of physics that can cope with the insanely high temperatures and pressures the universe experienced. All of our th
The actual spatial size of the universe is unknown. However, by measuring the observable universe, the current size of the universe is approximately 95 billion light-years in diameter. Humanity once believed that the night sky was the unilluminated sphere that enclosed Earth when the Sun was slee...

Astronomy should, in principle, be a welcoming field for a legally blind researcher like Kane. We are long past the era of observers huddling at the eyepiece of a giant telescope. Today, most astronomical studies begin as readings of light broken down by intensity and wavelength, digitized and...
Cutscenes can go a long way by using the language of cinema. The 3D medium makes anything possible with a camera, but that’s not always a good thing. It doesn’t matter how clever or how impressive a camera move can be; if it is detrimental to storytelling, it’s useless. Movies ha...
Secrets of the dark ages To investigate the dark ages, one avenue scientists are pursuing involves hunting for the earliest stars and galaxies. Since it takes light time to travel, light that came from far away also must have come from long ago. As such, astronomers look deep in space to...
