John Chumack nails Comet Garradd

Posted 13 years ago by David Eicher

There’s a reasonably bright comet in the sky right now — Comet C/2009 P1 (Garradd), discovered by Australian amateur astronomer Gordon Garradd. The comet is now visible through binoculars and small telescopes, an evening object glowing at around magnitude 8, and showing a nice, intense, bright green coma. The comet is in the tiny constellation Sagitta in the summer Milky Way, and will continue to be visible for some time to come. Astronomy magazine contributor John Chumack captured ...

Sizzling hot image of the week: Heckathorn-Fesen-Gull 1

Posted 13 years ago by David Eicher

Rarely do you get a look at a planetary nebula that’s this old. The endgame for Sun-like stars, planetary nebulae — so named because many years ago their disks appeared like planets in the eyepiece — are clouds of gas slowly dissipating into surrounding space. They’re one of the methods the universe uses for its stellar recycling program. Noted astroimager Don Goldman recently captured an amazing planetary nebula, Heckathorn-Fesen-Gull 1. What sounds like the first case o...

More Perseids from Ohio

Posted 13 years ago by David Eicher

A few days ago, I shared an image of some Perseid meteors captured by John Chumack at his observatory near Dayton, Ohio. Although the Moon was very close to Full and, therefore, the conditions hardly ideal this year, observers did catch quite a few Perseids over the past several days, and I hope you were one of them. I have the pleasure of sharing another image of John's, this one taken August 12, when he captured more than 100 meteors. For more on John's astroimaging, see http://www.g...

Here come the Perseids!

Posted 13 years ago by David Eicher

I hope you are looking forward to the peak of the Perseid meteor shower, which takes place Saturday, August 13, the same day as the Full Moon. Although the Moon phase stinks this year for the shower, you still may see as many as 20 decent meteors per hour under clear skies. Well, whether you go out or you don’t, you can still enjoy this fantastic image of pieces of Comet Swift-Tuttle captured by astroimager John Chumack last night. John had meteor cameras running at his observatory near D...

Stars and lava in Hawaii

Posted 13 years ago by David Eicher

You may have heard about the major breakout of lava at Kilauea volcano on the Big Island of Hawaii that took place last week. On Thursday and Friday, crater walls collapsed and sent rivulets of lava trickling down to the ocean in a spectacular scene that made the ordinary lava viewing seem very ordinary. It constituted another stage in the eruption of Kilauea’s middle east rift zone. Astronomy Contributing Editor Steve O’Meara and his wife Donna live on the Big Island and are volcano...

Meet Comet Garradd

Posted 13 years ago by David Eicher

If you haven’t looked at Comet C/2009 P1 (Garradd) yet, you might want to check it out. Discovered by Australian amateur astronomer Gordon Garradd, the comet is currently a respectably bright binocular object, at magnitude 8.7, located in the late evening sky in the constellation Pegasus. Here, I present to you two fresh images of the comet from July 29 from our great astroimaging friend Anthony Ayiomamitis in Greece. His shots depict the comet tracked on the nucleus, which trails the sta...

A tale of two stories

Posted 13 years ago by David Eicher

The August issue of Astronomy magazine contains two special articles. For those who have not seen or read them yet, I want to share them with you here — because they are important to the future of astronomy as an interest. The first was written by 14-year-old astronomy enthusiast Ayla Besemer, an energetic young lady who travels the globe with her parents on a ship (see threeatsea.com) and is very devoted to observing the sky.

The sweetest shuttle landing shot

Posted 13 years ago by David Eicher

OK, I know I've thrown lots of shuttle images at you over the last couple of weeks, but pretty soon there won't be any more to celebrate from recent history, so bear with me. I had to share the greatest image I've seen of Atlantis' landing, which concluded the STS-135 mission and the Space Shuttle Program, from friend and astroimager Chris Cook, who was in Florida covering the event for Astronomy. What a striking image this is! Enjoy! ...

Amateur astronomer images water-laden quasar

Posted 13 years ago by David Eicher

Well, Greek astroimager par excellence Anthony Ayiomamitis has done it again. Just a day after I told you about Anthony’s extraordinary image of the brown dwarf LSR0602+3910, he sent me an image and some links regarding another big recent news story. A few days ago, NASA researchers announced the discovery of the largest reservoir of water known in the cosmos. This reservoir, which amounts to 140 trillion times the amount of water on Earth, exists in a cloud surrounding an enormous black h...

One night in a cornfield — Part Five

Posted 13 years ago by David Eicher

In 1687, with the publication of Isaac Newton’s Philosephiae Naturalis Principia Mathematica (“Mathematical Principles of Natural Philosophy”), the telescope’s journey had already lasted 77 years, but really it had just begun. For the first time in history, humans were elevated intellectually to looking up at the sky at night and seeing almost limitless heavens with numerous surprises waiting. Still to come was William Herschel’s discovery of Uranus, the first plane...

One night in a cornfield — Part Four

Posted 13 years ago by David Eicher

The first national observatory, in Copenhagen, Denmark, was established in 1637. In the Netherlands, Christiaan Huygens described Saturn’s rings, discovered its moon Titan, and found light and dark markings on Mars. Observatories sprang up in Paris and at Greenwich, England. For the first time, astronomers began observing the sky of the Southern Hemisphere, noting a decidedly different group of stars, constellations, and features from that which they saw from the north.Technologically, all...

One night in a cornfield — Part Three

Posted 13 years ago by David Eicher

It was 400 years ago when Galileo sparked a transformation of thinking on this planet. What Galileo found immediately astonished him and established the first large step in observational astronomy.He saw that the Milky Way, the luminous band in the night sky, was composed of innumerable stars. He observed the phases of Venus and discovered four little moons orbiting Jupiter. He witnessed sunspots and saw Saturn’s rings, although he mistook them for moons that were poorly resolved. When Gal...

One night in a cornfield — Part Two

Posted 13 years ago by David Eicher

Carefully using a red-filtered flashlight to preserve his eyes’ sensitivity to faint light, the boy made a quick drawing on paper of how the Andromeda Galaxy appeared with his 8-inch telescope on that late summer night. The bushes continued to rustle, the breeze shot through the trees, and Larry King continued to belt out questions on the radio. It was one more tiny moment in the history of the telescope — an instrument that has revolutionized science and our knowledge of the univers...

One night in a cornfield — Part One

“The cosmos is all that is or ever was or ever will be. Our feeblest contemplations of the cosmos stir us — there is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, of falling from a height. We know we are approaching the greatest of mysteries.” — Carl Sagan, Cosmos In the deep dark of a summer night, leaves rustled in the trees, a slight breeze washed overhead, and bright, gemmy stars twinkled in a deep azure sky. It was a moon...

Here’s to galling congressional stupidity

Posted 13 years ago by David Eicher

Well, the United States House of Representatives has done some dumb things in its time, but yesterday it may have equaled its best. The House Appropriations Committee proposed killing the James Webb Space Telescope (JWST), the centerpiece of NASA’s plans for exploring the universe over the coming decade. The JWST is planned to be an infrared telescope and the successor to the Hubble Space Telescope, whose orbit will decay over the next few years until it burns up in our atmosphere. Origin...
