Ho, ho, ho for Halley’s Comet

Posted 15 years ago by Daniel Pendick

On Christmas Day, 1758, a German amateur astronomer and farmer named Johann Georg Palitzsch did something that would have made a great Christmas gift for English astronomer Edmond Halley. Johann “recovered” Halley’s Comet, meaning he was the first to observe this previously observed “dirty snowball” as it returned to the inner solar system. Edmond Halley (1656-1742) calculated the orbit of the comet that now bears his name based on previous sightings. He determined that the same comet was respo...

Enceladus ice tectonics: Cassini’s latest mind-blowing image of another world

Posted 15 years ago by Daniel Pendick

Many phases of the Moon ago — more than 200 — I came under the spell of earth science and wrote a lot about it for a number of years. This week, some of that ancient knowledge came back to visit as I gazed at a fantastic 28-image mosaic of Saturn’s moon Enceladus. You may see crusty cracked ice; I see the outlines of ice continents. At the American Geophysicial Union meeting in San Francisco this week, the halls are abuzz with talk of plate tectonics on Enceladus. Using Cassini-based d...

Geminid meteor image from John Chumack

Posted 15 years ago by Karri Ferron

Noted astrophotographer and Astronomy contributor John Chumack sent us a still image of the Geminid meteor shower, which peaked December 13/14. He shot the photo from his observatory in Dayton, Ohio. Read John’s comments below. My backyard observatory’s “Northeast Video Sky Camera” captured 10 of the brightest Geminid meteors — despite the very bright and big Full Moon, some fog, and high cirrus clouds — from around midnight until 3 a.m. EST Monday, December 15 (unfortunately we lost power ...

Telescope fever

Posted 15 years ago by Liz Kruesi

I just finished writing an article about the telescope’s history (you know, with the International Year of Astronomy coming up in 2009). I know that in the astronomy world aperture fever runs wild, but wow, some of these telescopes are just ginormous!! It must have been quite an experience just to operate something like the 72-inch “Leviathan of Parsonstown” — even though telescopes like the Yerkes 40-inch (pictured at right) and Lick 36-inch refractors were much better balanced, which made posi...

Happy birthday to a grand old telescope

Posted 15 years ago by Daniel Pendick

California’s Mount Wilson Observatory (MWO) is celebrating the centennial of its famous 60-inch reflecting telescope. Upon its completion in 1908, the “60-inch,” as astronomers call it, was the largest telescope in the world. Pioneer astronomer George Ellery Hale commissioned the project under the auspices of the Carnegie Institution of Washington. The 22-ton behemoth saw first light December 13, 1908, and is considered the grandparent of all modern research telescopes. Harold McAlister, MWO’...

It's gonna be a long year

Posted 15 years ago by Michael Bakich

If you feel like time is dragging, you’re right, at least partly. Actually, it’s Earth that’s dragging, and its lackadaisical attitude will be responsible for 2008 being a longer year. Oh, joy. Like it hasn’t been long enough already. On December 31, the U.S. Naval Observatory (USNO) will add a “leap-second” at its Master Clock Facility in Washington. Together with the National Institute of Standards and Technology, the USNO determines time for the United States. Countries around the world wi...

The Milky Way’s center of attention

Posted 15 years ago by Daniel Pendick

Did a parent, boyfriend/girlfriend, spouse, supervisor, etc., ever say to you in an argument, “You’re not the center of the universe, you know!” Well, sorry to disappoint, but you’re not the center of the galaxy either. That honor belongs to a black hole that weighs between 4,250,000 and 4,370,000 times the Sun’s mass and lies somewhere between 26,028 and 27,169 light-years from Earth. How do I know? Because German astrophysicist Reinhard Genzel and his team at the Max-Planck-Institute...

An art exhibition on Mars

Posted 15 years ago by Matt Quandt

Michael Carroll, renowned illustrator and a frequent art contributor to Astronomy magazine, sent us his musings on the Phoenix Lander’s fate. Because his father worked at the Martin Marietta (now Lockheed/Martin) facility in Littleton, Colorado, Michael enjoyed unique access to the early stages of the Viking missions. His two latest books are Space Art: drawing and painting planets, moons and landscapes of alien worlds and Alien Volcanoes (Johns Hopkins University Press). Both are available thro...

Relativity rap

Posted 15 years ago by Liz Kruesi

It’s great how some people communicate science ideas. A few months ago we heard about the science writer at the Large Hadron Collider who filmed a rap video about the LHC and posted it on YouTube.So what does this have to do with Astronomy? Well, Rob Wheeldon, a reader and fellow astronomy enthusiast from the U.K., recently sent us a letter that included his own rap. This one, however, doesn’t concern the LHC, but instead a very complex subject: relativity. Wheeldon told me that his inspiration ...

Video of Jupiter, Venus, and Moon conjunction

Posted 15 years ago by Michael Bakich

Here’s an “extra” for those of you who saw the nice conjunction December 1 featuring Venus, Jupiter, and the crescent Moon. Amateur astronomer Ian Sharp, who lives in Ham, England, just sent me two videos. The first shows the Moon (you can’t really see it, but trust me, it’s there) covering the shimmering disk of Venus. The second video shows Venus reappearing from behind the Moon’s edge. Astronomers call such an event an occultation. In this case, the Moon occulted Venus. Because of the geome...

So what does Comet 96P/Machholz smell like?

Posted 15 years ago by Daniel Pendick

This week, Astronomy.com reported some intriguing comet research at Lowell Observatory in Arizona. A Lowell scientist, Dave Schleicher, studies the chemistry of comets. He and his colleagues recently found that Comet 96P/Machholz 1 has a weird chemistry. Machholz is extremely low in a chemical called cyanogen compared to other comets. The Lowell researchers think it may be a totally new class of comets, possibly cooked up billions of years ago in a very different way than their comet comrades in...

Planetary conjunction reflection and pictures

Astronomy magazine’s offices are located in an office park off I-94 in Waukesha, Wisconsin. I’m one of the lucky people here blessed with a corner window that provides a pretty wide view of the sky.In summer, I watch wicked thunderstorm systems scudding due east on their way to die over Lake Michigan. During early evenings — when you can sometimes find some of us in our offices dotting i’s and crossing t’s on the latest astronomical discoveries — pastel sunsets drape the sky. But today I see sno...

Q&A with Stephen J. O’Meara about his new binocular book

Posted 16 years ago by Daniel Pendick

This month, Cambridge University Press published Astronomy columnist Stephen James O’Meara’s latest book for stargazers, Observing the Night Sky with Binoculars. The book — billed as “a simple guide to the heavens” — is for beginners. This is a new direction for Steve, who has published several guides to observing deep-sky objects with telescopes. I asked him why he wrote the book and how readers could benefit from it. Pendick: How did this book come about? When and how did you get the idea...

One small step for ... Ooops!

Posted 16 years ago by Daniel Pendick

I just received a media advisory from James Oberg, a contributor to Astronomy and noted space historian. And I learned something new — something historic. Something I’m a little embarrassed I didn’t know. It appears that many video producers continue to misrepresent Neil Armstrong’s comments the day he stepped onto the Moon (that's Apollo 11 astronaut Buzz Aldrin pictured at right). Oberg explains it best:The National Geographic Channel is running “Expedition Week” with several space-relate...

Shuttle Endeavour ready for liftoff

Posted 16 years ago by Karri Ferron

Today’s the big day of Endeavour’s STS-126 mission (assuming the weather holds up), and I must admit that I’m pretty excited. I’m not sure why, but I’ve always been fascinated with space travel, specifically the launches. I never actually wanted to be an astronaut (too afraid of flying and not much of a risk taker), so I live vicariously through the men and women who do have the opportunity to be blasted off into space. I can’t even imagine how thrilling liftoff must be for them, but I plan on w...

On the road: Advanced Imaging Conference preview

Posted 16 years ago by Michael Bakich

This weekend, 270 avid astroimagers from around the world are converging in San Jose, California, for the 2008 Advanced Imaging Conference (AIC). And guess what? I’ll be there, too.AIC’s board of directors invited me to speak at the conference because of the buzz Astronomy generates among astroimagers.
