The story of Hubble’s Deep Field image

The Hubble telescope’s Deep Field image from 1995 is one of the most important images in human history. I’ve been fascinated by it since I first heard about it in a talk by the neuroscientist, David Eagleman. (Great talk. Add it to your must watch list.) I regularly bring up the Hubble Deep Field image […]

Kurzgesagt: The universe is crazy big

This video* is chock full of insights that clarify complicated concepts about the size of the universe. And it’s a sobering reminder of just how small we are. The video points out that the local group of galaxies—that includes our Milky Way and the neighboring galaxies that are close enough to ever possibly consider exploring in some […]

Goodnight, Earth

Earth, early to the party

This is fascinating: Earth came early to the party in the evolving universe. According to a new theoretical study, when our solar system was born 4.6 billion years ago only eight percent of the potentially habitable planets that will ever form in the universe existed. And, the party won’t be over when the sun burns […]

To Scale: A short film to put you in your place

But they are nowhere close to representing the true scale of the size of the solar system. Wylie Overstreet and Alex Gorosh made this amazing short film […]

Cassini, Saturn, Dione, and hope

   NASA’s Cassini probe this week sent back stunning photos of Saturn’s moon, Dione, which is one of the 64 moons orbiting the crown jewel of the solar system.  That thin black line behind Dione in the image above is the edge of Saturn’s rings. Amazing.  We can fling a tiny piece of gadgetry a […]
