HR Diagram

The Hertzsprung Russell Diagram is the "Rosetta Stone" of stellar astronomy and it's simple, very simple. So to put it simply, it's just a graph that plots lots of stars' luminosities against their surface temperatures. As simple as that sounds, it is the key to understanding stellar evolution.In case you thought "Rosetta Stone" is some sort of educational software for travelers, it is. But it's also an actual…See More

"Good stuff. Last nights episode of "Cosmos" touched on William Herschel and his theorys of time, space, and the speed of distant star light."

History of Astronomy Part 2

Edmund Halley 1656-1742Among his many studies are tides, magnetism, and trade winds. He cataloged 341 southern hemisphere stars and discovered a star cluster in Centaurus. He also made the first complete observation of a transit of Mercury on November 7, 1677. He also invented the diving bell. But his most famous accomplishment is…See More

History of Astronomy Part 1

There have been thousands of science geeks contributing to astronomy over the centuries and millennia. Here are a mere handful that have been selected from some of the most significant figures. Some of these people are real icons of human history, big thinkers. As Isaac Newton once said "If I have seen farther than others, it is because I have stood on the shoulders of giants." These are those giants of history,…See More

"We have barely audible low freqs at my place (rural pacific northwest) that are hard to ignore at night, at least in the winter. Now the frogs are awake and cover them up with their chorus. Any idea what they could be? I've seen on the web that…"

Not to scale. "The infinitude of creation is great enough to make a world, or a Milky Way of worlds, look in comparison with it what a flower or an insect does in comparison with the Earth." ~ Immanuel Kant



Galaxies are monstrous collections of stars, plus dust, gas, light matter, dark matter, and gray matter. In a fundamental way galaxies are…
