Sometimes when I take my dogs outside on a cold clear night in Maine I look up at the sky and I try to wrap my head around the size of the universe. Tonight was one of those times. Over the last couple of years I’ve shared some resources that can help viewers understand the scale of things in the universe, here they are.

The Scale of the Universe 2
features a huge selection of objects in the universe that are arranged
according to size and scale. You can zoom-in on the image to objects as
small as neutrinos and quarks or as large as planets, constellations,
and galaxies. When you click on an object in The Scale of the Universe 2
a small window of information about that object pops up.

3D Solar System Web is a neat website that I discovered through the Chrome web store.
3D Solar System Web features a narrated tour of the solar system
beginning at the sun and working out through all of the planets. The
tour explains the classifications of each planet, how long it takes each
planet to orbit the sun, and each planet’s unique features.

Magnifying the Universe is an interactive infographic that allows you to see the size of atoms, animals,
buildings, mountains, planets, stars, and galaxies in relation to other
objects in the universe.

100,000 Stars is a Google Chrome Web GL Experiment that does a good job of helping viewers understand the scale of the universe. 100,000 Stars
is a visualization of the 100,000 stars closest to Earth. You can view
the stars on your own or take an automated tour of the stars. that also does a good job of helping viewers understand the scale of the universe. 100,000 Stars
