Cool lunar eclipse image

Posted 15 years ago by Michael Bakich

You know, it’s not often that I get excited about a partial lunar eclipse. Yes, the “near-perfect” alignment is cool, but it doesn’t get all that dark, and I just find myself wishing the event was a total eclipse.Well, here’s an image I’m really jazzed about. It came to me (as Photo Editor) from one of our long-time imagers, Anthony Ayiomamitis, who lives in Athens, Greece. When I look at his image, I can almost feel the Moon moving through Earth’s shadow.For more of Anthony’s images, check out ...

Observing the Perseids

Posted 15 years ago by Megan McChain

As a working college student, I rarely have time to squeeze observing into my busy schedule. However, this week, the Perseid meteor shower presented the perfect opportunity to catch an early morning sky show. So, last night, with a friend and a couple lawn chairs (no binoculars or telescope needed), I drove about 50 miles away from the bright lights of Milwaukee to watch the peak of the shower. The shower was better than I expected. We settled into our observing site around 1 A.M. and watched f...

Reflections on the eclipse

Posted 15 years ago by David Eicher

With a statue of Lenin in the foreground, Boris Stromar imaged the eclipse from Novosibirsk, Russia. It looked grim the day before and grim the day after. But we stood under a blistering hot sky near Novosibirsk, Siberia, with nary a cloud in the sky on eclipse day. Never have I seen such perfect eclipse weather. The eclipse was beautiful, lasting 2 minutes 20 seconds, for our intrepid 160 travelers who came along with Astronomy magazine and MWT Associates to witness totality on Augus...

Twilight ringed the horizon above the Ob Sea during the August 1 total solar eclipse. Rich Talcott photo The weather forecast for August 1 in Novosibirsk, Russia, didn’t look promising. On the evening of July 31, the most favorable prediction called for partly cloudy skies, while the more pessimistic predicted a 70 percent chance of rain. Fortunately for Astronomy Editor Dave Eicher and me — and more than 150 fellow eclipse chasers with our MWT Associates eclipse tour — th...

Big Orange helps astronomy

Posted 15 years ago by Anonymous

I’ve never been a fan of Home Depot. My typical experience involves trying to locate an employee for assistance, only to find an apathetic teenager who doesn’t know a coupling from a chicken coop. I do my best to avoid Big Orange in favor for my local mom-and-pop hardware store. Despite my disdain for Home Depot, I have to tip my hat to Big Orange. The chain recently agreed to provide a new roof for the Custer Institute in Southold, New York. The Long Island astronomy center hosts several...

Introducing NASA’s “lone gunmen”

Posted 15 years ago by Daniel Pendick

NASA’s lone gunmen say they have designed a better, safer, cheaper version of the Ares I crew launcher (above), one of the cornerstones of the post-Shuttle space program. NASARemember the “lone gunmen,” the trio of militantly nonconformist Uber-geeks on The X-Files who tracked government conspiracies? It appears NASA’s got an infestation of them, too. In a story this week by Jay Reeves of the Associated Press, I learned of a merry band of dissident NASA engineers and managers ...

Extreme observing

Posted 15 years ago by Anonymous

Several astronomy clubs send us their newsletters covering group activities and upcoming sky events. I recently received “Desert Skies” from the Tucson Amateur Astronomy Association. While perusing it, I came across the story concerning rattlesnake alerts for observers. Holy cow! Now that is an observing site danger. Here in Wisconsin, I think the only wildlife danger at an observing site would be blood loss from mosquito attacks. I suppose it is a fair trade for those dark skies. Altho...

Prolific SOHO reaches benchmark

Posted 15 years ago by Anonymous

On June 25, the Solar and Heliospheric Observatory (SOHO) discovered its 1,500th comet. This tally tops all other comet discoverers throughout history combined. From ESA: When it comes to comet catching, the SOHO has one big advantage over everybody else: its location. Situated between the Sun and Earth, it has a privileged view of a region of space that can rarely be seen from Earth. From the surface, we can see regions close to the Sun clearly only during an eclipse. Roughly 85% of SOHO disc...

Pluto has been plutoided!

Look out, here comes the “Is Pluto a planet?” debate — again. I wade into these waters with trepidation and wearing armored hip waders. But on the other hand, how often does a guy get a chance to stir up a pot of angry astro-hornets? I won’t regurgitate the backstory. If you are reading this, you have a browser and an Internet connection. If you are not current on the drama, just Google “Is Pluto a planet?” and come back when you recover from your seizure.

How to make a bad first impression

Not much, it seems. The University of Leicester helped Doritos — yes, THAT Doritos — send a message to a solar system 42 light-years away in the constellation Ursa Major. What was the communication? A peaceful salutation? A threat? Nope, it’s a Doritos ad. From a University of L...

The orbits of stars within the central 1.0 X 1.0 arcseconds of our galaxy. Andrea Ghez/UCLA Reinhard Genzel, a researcher at the Max Planck Institute for Extraterrestrial Physics in Garching, Germany, has won this year’s Shaw Prize for astronomy. Genzel pulled off a pretty neat trick by observing individual stars circling the center of the Milky Way, our home in the universe. The stars he observed were close to the galactic center — within light-hours, not light-years, of the center. ...

Survival of the fittest

Posted 15 years ago by Michael Bakich

Astronomers now recognize 88 constellations. A memory aid I’ve used through the years is that there are the same number of constellations as keys on a full piano keyboard. Today’s star groups cover the sky with no overlaps and no gaps between them. This, however, is a fairly recent development. Before 1928, celestial mapmakers were free to populate the skies as they pleased, with only the mildest restraint placed upon them by astronomers and other cartographers. The fact that many of the star g...

Are quirky supernovae “quark novae”?

Posted 15 years ago by Francis Reddy

Three of the most luminous supernovae on record — 2006gy, 2005gj, and 2005ap — pose problems for theorists. For example, 2006gy’s peak luminosity reached 50 billion Suns. That’s 10 times brighter than the average type Ia supernova and 100 times brighter than a representative type II. And 2005ap was 2 times brighter still. What’s a theorist to do? In our January issue, I noted that astronomers suspected some of these events might be so-called “pair-production” supernovae. This mechanism wa...

The show is designed to reach anybody with an interest in the sky, who may have seen astronomy information on television or the web and wants to learn more. This is an exciting time for the hobby. Before, interested people had to rely on magazines, books, newsletters, or group meetings as their resources. Now, we also can tap into video and audio files from web sites. Because of technology and e...

A second helping of astro-hype

Posted 15 years ago by Daniel Pendick

Have you heard the news? Astronomers have observed the early phase of an exploding star. It’s 2008d, the “supernova caught in the act.” If you are in the science media, you can’t help having heard about it. For days, we’ve been in the midst of a blitz that would make the Luftwaffe envious. Fortunately, the supernova discoverers are firing press releases at us, not dropping bombs. At one point yesterday, I almost reached for my spam filter. As is often the case, multiple scientists had a han...

NASA engineers propose to get up close and personal with an asteroid

NASA engineers have proposed a mission to an asteroid threatening Earth. Bruce Damer (DigitalSpace) I’m happy to report NASA may be planning to do more about the as-yet unaddressed asteroid threat to Earth than helplessly watch giant space rocks whiz by the home planet from time to time.
