    Eclipse report from Jay Pasachoff

    Posted 10 years ago by David Eicher
    Today’s annular eclipse was visible widely across Australia and other areas of the South Pacific, and early reports have it as a big success. I take pleasure in sharing the report sent by Jay Pasachoff, astronomer at Williams College and a longtime contributor to Astronomy: We can report good success in observing 4 minutes 20 seconds of annularity at the eclipse today, about 62 miles (100 kilometers) north of Tennant Creek, Northern Territory, Australia. On one side of the road, ther...

    Another Brian May 3-D image of Comet PANSTARRS!

    Posted 10 years ago by David Eicher
    Yesterday, I shared a cool 3-D image of Comet PANSTARRS sent by Ph.D. astronomer, Queen guitarist, and Astronomy Editorial Advisory Board member Brian May. Today, I have the good fortune to share another image Brian sent me. You may know that Brian is very much into stereo photography (see “Brian May’s world of stereo astro imaging,” Astronomy, January 2012), and he has produced these very cool shots with images taken by a number of astroimagers. You can view them by relax...

    Posted 10 years ago by David Eicher
    My book, Comets: Visitors From Deep Space, will be published this fall by Cambridge University Press. Here’s a taste of a historical chapter centering on observations by the Roman philosopher Seneca . . .Enjoy! The Roman philosopher Lucius Annaeus Seneca, aka Seneca the Younger (ca. 4 B.C.–A.D. 65), summarized the early take on comets — as opposed to the always visible parts of the heavens, the Sun, Moon, etc. — in one of his writings. “No man is so utterl...

    Astronomical League searches for young astronomers

    Posted 10 years ago by David Eicher
    When I was at NEAF in New York last weekend, Astronomical League Vice President John Goss asked me about young people in amateur astronomy. He showed me a copy of the March issue of Reflector, the league’s monthly publication, with the theme of “You and Astronomy.” I hadn’t seen the issue, having been on several recent trips, but was glad to read it carefully. For some years, astronomy enthusiasts have noticed the regular meetings and star parties they’ve atte...

    News from the Astronomy Foundation

    Posted 10 years ago by David Eicher
    Over the past three weeks, I’ve taken a vacation down the Mississippi River, speaking about the Civil War on the American Queen riverboat, and also gone to the Northeast Astronomy Forum (NEAF), the biggest astronomy expo in the United States, in Suffern, New York. I am very tired, but glad to be back finally in the normal routine. NEAF was terrific, and I enjoyed meeting many of you there — thanks for all the great comments on the magazine and everything that’s going on h...

    NASA outreach/education caught in sequestration morass

    Posted 11 years ago by David Eicher
    You know, I can remember when the American government worked — at least at times. The recent standoff with regard to budget in Washington and the resulting sequestration mess underscores the functionality of Congress at an all-time low. It’s really ridiculous, given the nation’s history, but so be it. For the time being, another victim of the sequestration fiasco is the slate of educational and outreach programs put on by NASA, which are now in a state of suspension. NASA ...

    Name a planet for science!

    Posted 11 years ago by David Eicher
    Our solar system may be down one planet from the good old days, but astronomers have now found more than 860 worlds orbiting stars near us in the Milky Way Galaxy. More than 1,000 other candidates are likely planet detections that astronomers have not yet fully analyzed. That’s an astonishing feat, taking human knowledge of the vast realm of space beyond our local neighborhood that philosophers only could have dreamed about a generation ago.Despite such incredible advances in astronomy, ho...

    Pi Day — and a little more

    Posted 11 years ago by David Eicher
    Yesterday at noon, the staffs of Astronomy and Discover magazines got together down in our company’s lunchroom and had a very nerdy lunch — by celebrating everything that was round. Yes, Pi Day struck us large again. Liz Kruesi, our associate editor, is the chief instigator, and everyone brought a huge splash of round stuff, savory and sweet, to mercilessly cast into our stomachs. We stood around and joked and had a generally good time as we were taking a brief break from the ve...

    Lowell Observatory launches Clark Telescope Renovation Campaign

    Posted 11 years ago by David Eicher
    Few institutions in astronomy have the kind of ethereal sense of history that comes from Lowell Observatory in Flagstaff, Arizona. Established by Percival Lowell in 1896 and featuring one of the great refractors on Earth, the 24-inch Clark used by Lowell and others, the observatory is famous for its research on Mars and many other areas. One of the great unsung moments in the history of astrophysics happened at Lowell when in 1912 astronomer Vesto M. Slipher was the first to notice shifts in th...

    Steve O'Meara, Botswana, and Comet PANSTARRS

    Posted 11 years ago by David Eicher
    Astronomy magazine columnist Steve O’Meara is currently traveling in Botswana, a country in southern Africa. Early this morning, he emailed me to update his observations of Comet PANSTARRS (C/2011 L4), and the paragraph was so beautifully composed I thought I’d share it with you. Enjoy as we wait for the comet to emerge for us northerners. “I got my first view of Comet 2011 L/4 (PANSTARRS) last night (3/5/13 LT) and was amazed. At the moment, from the pioneer village of Maun (t...

    Dave Eicher Comet ISON blog on “The Huffington Post”

    Posted 11 years ago by David Eicher
    “Living our 2-D lives on planet Earth, arguing over Sequestration and who has the remote, we tend to forget that the solar system is a cosmic shooting gallery. The point returns on rare occasions like last month's Russian meteorite fall, but we are generally oblivious to the number of rocks and dirty iceballs floating around our cosmic territory that could see planet Earth as an opportunistic target.”So starts my blog written about the prospects for Comet ISON, which I was asked to w...
