Almost Heaven (Star Party), West Virginia

Once in a while, you have to get yourself to dark skies. Forget the excuses, the lost sleep, the long drive. Just go. It will regenerate you, reconnect you to the cosmos, and help you remember why you became a stargazer in the first place.

Which is why I powered down the computer and packed a simple Dobsonian telescope, a binoviewer, and a couple of eyepieces and headed out to the Almost Heaven Star Party (AHSP) in West Virginia, an event held this year on September 2-6, 2016 [Read more…] about Almost Heaven (Star Party), West Virginia

Why Be an Amateur Astronomer

June 23, 2016 by Brian Ventrudo Filed Under: Stargazing

Why-Be-An-Amateur-Astronomer

A lifelong amateur astronomer, Al Nagler worked as a professional optical engineer and designed optics for the flight simulators of the Gemini and Apollo space programs. In 1977, he started his own company, Televue, to design and build premium refractor telesopes and eyepieces with the goal of making stargazing easier and more enjoyable for everyone. He is also the inventor of the famed Nagler wide-field eyepiece, an optical innovation that has vastly improved the visual views of the night sky through a telescope.

In a piece written in 2000 by David Levy, Al spoke of his love of astronomy: “Astronomy is the most wonderful pursuit. If we had more amateur astronomers in the world, we’d solve a lot of fundamental problems. The more people who enjoy and understand our place in the universe, the better our own planet will be. And if I am a Pied Piper in this regard, that’s what I want to be.”

Strawberry Moon and Summer Solstice Meet

Today the Sun reaches the June solstice, its most northerly point on the celestial sphere. This marks the first day of summer in the northern hemisphere and the first day of winter in the southern hemisphere. And for the first time in 68 years, the June solstice occurs on the same day as the June full Moon, often called the Strawberry Moon [Read more…] about Strawberry Moon and Summer Solstice Meet

Sun Unexpectedly Swells to Red Giant

April 1, 2016 by Brian Ventrudo Filed Under: Stargazing

The Sun unexpectedly has swollen to a red-orange on April 1, 2016 as seen over southern California.

In a development that has shocked astrophysicists around the world, the Sun has unexpectedly run out of hydrogen fuel in its core. As gravity squeezed the collapsing core, the dense plasma increased in temperature and ignited helium burning, causing the outer layers to swell into a red giant. Reports suggest the two inner planets, Mercury and Venus, have been swallowed by the expanding star. On Earth, students in the northern hemisphere have been released from school to start summer break early. While astronomers are perplexed, health professionals strongly recommend a thick layer of sunscreen for anyone venturing outside, at least until someone can figure out how to restock the supply of hydrogen gas in the Sun’s core.

In a media report, Professor Cedric Doppleganger, of the California Institute of Astrophysics, said that although the Sun’s sudden expansion violates all known laws of physics, that researchers are undeterred. “It just goes to show that the science of solar physics isn’t so settled after all.”

The Dark Universe

It’s been too long since I’ve been in a good planetarium, but this past weekend I saw the splendid “Dark Universe” show at the Hayden Planetarium (pictured) in New York. With dazzling graphics, a lapidary script by Timothy Ferris and narration by Neil deGrasse Tyson, the movie summed up in style the most important discoveries in cosmology over the past 100 years. If you’re visiting NYC, skip an afternoon of shopping and go to the Hayden. It’s worth the trip.
