Solar System Scale: Copernicus’ Method
Nicolaus Copernicus’ (1473 – 1543) paradigm-changing work de Revolutionibus Orbium Coelestium (On the Revolutions of the Celestial Spheres) famously laid the groundwork for the overthrow of the geocentric universe that had held sway for millennia. But what many people...

Sulawesi Earthquake in The Layered Earth
When we've been discussing applications of Starry Night in the dome, there was usually little need to worry about the human element, but with The Layered Earth (TLE) this is different. Most of the layers we use and stories we're going to tell are about consequences...

Gravity Waves From Neutron Star Collision
On August 17th, the Laser Interferometer Gravitational-Wave Observatory, or "LIGO", detected gravity waves produced by the merger of two neutron stars. There are lots of good takes on this story, and it's important that we keep retelling it in interesting ways. This...

Football and Astronomy
As the NFL season gets into gear (Go Bills!) it's time to mention football's deep connections with astronomy. The 1927 Broadway musical Good News, which gave us the popular song "The Moon Belongs To Everyone", is about the division in college life between sports and...

Simulating Near-Earth Asteroid 2012 TC4
For the last couple of days, there has been some news coverage of another small asteroid that's going to fly close to the Earth tonight. This happens fairly often, although it is a little unsettling when it does. We have just passed the 9th anniversary of the...

Roundness of the Earth
48 years ago last week Apollo 11 landed on the Moon. There is another anniversary last week that seems appropriate to mention at this point: On July 20th of 1925 the greatest scene in American legal history took place, and it was an astronomy lesson. You're probably...

Simulating Juno’s Buzz by the Great Red Spot
One of the astronomical highlights of last week was the pictures returned by the Juno spacecraft orbiting Jupiter when it zipped over the Great Red Spot at an extremely low altitude (8000 km.) Although the JunoCam camera on this mission was an afterthought for public...

Edison’s “Tasimeter” and the Eclipse of 1878
On July 29, 1878, Thomas Edison observed the total eclipse of the Sun as part of Henry Draper’s Expedition to Rawlins, Wyoming Territory. (Although this year’s total eclipse will pass through Wyoming, the City of Rawlins will be some distance south of the total path this time.) Edison was there to test a new invention that could detect infrared light and estimate the temperature of objects remotely, and he planned to try and estimate the heat of the Sun’s corona while the solar photosphere was blocked by the Moon.

The Total Solar Eclipse of 2017 in SciDome
The appearance of a total solar eclipse is so singular that it is impossible to appreciate it without having seen it for oneself. Unexpected eclipses have changes history in the past, although they can now be predicted. Even having an eclipse forecast in hand does not...
