The REAL First Day of Spring

Spring is on the way. Really! Despite the chilly weather and occasional snow dump, the second half of March invariably brings on scientific-sounding descriptions of something called the vernal equinox, the day when daytime and nighttime are finally equal. It marks the time when daylight starts lasting longer, nights get shorter, and (eventually) warm weather returns to our fair land.

What is rarely discussed, though, is why. Why should the Earth's axis tilt in such a way to create varying seasons? Why are seasons so predictable, year after year after year? Do other planets have similar cycles? Will our pattern ever change?

Prospect to Bellepoint – River mile 170.93 to 155.40

It was sunny and cool on June 15 when George, David and I headed to a put in point just south of the town of Prospect. We sited a Red Headed Woodpecker on the road that parallels the Scioto. River mile 170.93 is just below an old dam. A pipe that runs under the road carries run off from farm fields into the river. The high levels of algae growth indicate that nutrients, like fertilizer, are in the water that the pipe carries.

A Blast (of Gas) from the Past

Imagine you’re a Trogdorian, living on the planet Trogdor seventy-five light years from Earth. It is ninety million years ago, and your planet has just developed the technology to survey nearby worlds for signs of life.

You train your ultra-sensitive space telescope on a pretty solar system with a yellow star and eight smaller worlds stretched out like gemstones on a necklace. One of these worlds, third from its star, lies at a distance where liquid water might exist on its surface. Intrigued, you set your spectroscope to examine the atmosphere (if any) of this orbiting rock.

John Glenn - National Hero, Long Time COSI Friend

Today the world focuses again on the accomplishment of John Glenn and NASA in celebrating the fact that exactly 50 years ago, the world stopped while Glenn orbited the world three times as the first United States astronaut to do so. I vividly remember sitting in my classroom as we were riveted with the journey and holding our breath collectively with the danger of re-entry with a suspected problem with the heat shield.
