Today’s APOD is the 1977 video “Powers Of Ten” – the universe from different scales of magnitude!! #science

Today’s Astronomy Picture of the Day is more than a picture… actually a video!!! “How different does the universe look on small, medium, and large scales?”

Powers of Ten takes us on an adventure in magnitudes. Starting at a picnic by the lakeside in Chicago, this famous film transports us to the outer edges of the universe. Every ten seconds we view the starting point from ten times farther out until our own galaxy is visible only a s a speck of light among many others. Returning to Earth with breathtaking speed, we move inward- into the hand of the sleeping picnicker- with ten times more magnification every ten seconds. Our journey ends inside a proton of a carbon atom within a DNA molecule in a white blood cell. POWERS OF TEN © 1977 EAMES OFFICE LLC (Available at

How Many Stars Are There? – New video from @okaytobesmart

How many stars are there in the universe? Are there more stars out there than grains of sand on Earth? Thanks to advanced space telescopes, we’ve been able to peer farther into deep time and the distant universe than we ever thought possible, and we might finally be able to answer these mind-boggling questions.

How big (or small) is the universe?!


I’m not going to lie, this is one of the COOLEST things I have ever seen on the internet.  An interactive program to understand the scale of our universe… both large and small.  Brought to you by the htwins and of course, physics, chemistry, biology, medicine, etc.
