On the road: The Rose Center for Earth and Space

Posted 6 years ago by David Eicher
Following the Northeast Astronomy Forum in Suffern, New York, I traveled to New York City to work on a couple stories for future issues of the magazine. I won’t divulge exactly what they will be, but let me share a few photos of the day I had at the Rose Center for Earth and Space at the American Museum of Natural History. The Rose Center is the preeminent astronomy educational museum and planetarium in the United States, and it is under the direction of a good friend of the magazine, Neil...

On the road: The Northeast Astronomy Forum, April 16, 2011

Posted 6 years ago by David Eicher
The first day of the 2011 Northeast Astronomy Forum (NEAF) got off to a big start on the morning of Saturday, April 16, 2011, at the Eugene Levy Fieldhouse at Rockland Community College in Suffern, New York. More than 140 vendors were on hand, including all the large telescope manufacturers and many retail dealers, as well as numerous accessory producers and media such as Astronomy magazine.

A recent history of telescopes

Posted 6 years ago by David Eicher
On the eve of the Northeast Astronomy Forum (NEAF) in Suffern, New York, the nation’s largest astronomy expo, I’d like to reflect on telescopes. The history of amateur astronomy is filled with many memorable moments in scope technology. Those of us fortunate to attend NEAF this year will see a spectacular array of new equipment from numerous manufacturers. But what about some of the historical highlights of the amateur astronomy telescope market? This compilation of key dates, from ...

On the road: The Northeast Astronomy Forum

Posted 6 years ago by David Eicher
Tomorrow, I will fly east to Newark and then drive up to Suffern, New York, to attend the 20th anniversary of the Northeast Astronomy Forum (NEAF), America’s premier astronomy expo, which takes place at Rockland Community College April 16 and 17. (See http://www.rocklandastronomy.com/NEAF/index.html.) The event is driven by the energy and tireless work of many people, but none so much as Alan Traino, the Rockland Astronomy Club’s workhorse. I will report on the event this weeke...

Starman: The truth behind the legend of Yuri Gagarin

Posted 6 years ago by David Eicher
Lots of buzz shot across the Web yesterday to mark the 50th anniversary of Yuri Gagarin’s celebrated 108-minute spaceflight. That event ushered in a new era, and it’s amazing that we now have a half-century of space exploration under our belts, as well as 108 years of human flight. You probably read a few posts yesterday online summarizing the excitement over Gagarin’s orbital flight April 12, 1961, that made him a hero of the Soviet Union. A mere 7 years later, Gagarin was tra...

Adventures in pseudoscience — magnetic "therapy"

Posted 6 years ago by David Eicher
Have you ever been watching a movie late at night when you’re interrupted by one of these inane commercials for magnetic bracelets? You know, the ones that show people wearing a magnetized piece of metal on their wrist or as a pendant and somehow their lives are fully in order and all their health problems are magically fixed? Who are the people buying these cheap marketing gimmicks? Have they lost their minds? Did they have functioning minds to begin with? Do these people even know ...

What do the days of the week mean?

Posted 6 years ago by David Eicher
Astronomy’s roots in human culture run deep, and rarely more so than with nomenclature for our days of the week. Origins of the days of the week date to Sumerians around 5,000 B.C. The Romans revised them in A. D. 321. The Romans named weekdays after the “wandering stars” that moved through the sky and were thus “alive,” becoming candidates for worship as gods. At the time, seven such gods were known, which by coincidence matched the Biblical seven days ...
