The great conjunction of 2012 — and a Minute Man

Posted 10 years ago by David Eicher
I’m sure that if you had a clear sky over the past few nights, you’ve marveled at the great evening grouping formed by the Moon, Venus, and Jupiter. Talented astroimagers and old friends Imelda Joson and Edwin Aguirre captured the conjunction over the Minute Man Statue in Minute Man National Park, Concord, Massachusetts, on Sunday, February 26. “In the photo, the Moon is the most brilliant object in the western sky, with Venus below it and Jupiter to its left,” said ...

Hot image of the Sun by John Chumack

Posted 10 years ago by David Eicher
Check out this amazing shot of a solar prominence captured by astroimager John Chumack last Wednesday, February 22, from his backyard observatory in Dayton, Ohio. Enormous towers of plasma lift off the Sun’s disk in this spectacular shot. John used a Lunt 60mm Hydrogen-alpha LS 50F solar scope with a DMK 21AF04 Firewire camera and a 2x Barlow lens. He stacked and composited 742 frames to make the final image. Fantastic!...

Study suggests Earth-like planets could be very different from Earth

Posted 10 years ago by David Eicher
A revolutionary new study by a team of astronomers suggests that although the universe may be filled with planets similar to Earth, other Earth-like worlds may be quite different from our planet. Garik Israelian, an astronomer at the Institute for Astrophysics in the Canary Islands (AIC), alerted me to this fascinating study. He is one of the researchers involved, the others being Jonay González Hernández (also of the AIC); Jade C. Carter-Bond and David O’Brien of the Planeta...

Asteroid named for Mark Kelly and Gabrielle Giffords

Posted 10 years ago by David Eicher
Bob Gent, activist and former president of the Astronomical League, forwarded this news as reported in the March issue of The Reflector, which is just out. Former Congresswoman Gabrielle Giffords and her husband, astronaut Mark Kelly, have received the honor of a minor planet named for them. Giffords, who was tragically and critically injured in the Tucson, Arizona, shooting of January 8, 2011, resigned from Congress in January of this year. Kelly is still an active astronaut and is a Navy veter...

New killer Mars shot from Don Parker

Posted 10 years ago by David Eicher
Legendary astroimager Don Parker of Coral Gables, Florida, has sent an amazing new shot of the Red Planet he made February 20, 2012. “The north polar cap’s edge appears to be breaking up as it enters the rapid regression phase,” said Don. “Late morning cloud over Ascraeus with clouds and hazes extending from eastern Tharsis across Candor and Chryse. Post-front seeing was highly variable.” A great martian image and Red Planet weather report for the middle of the...

Killer image of supernova remnant Simeis 147

Posted 10 years ago by David Eicher
California astroimager Rogelio Bernal Andreo has scored again with a stunning image of Simeis 147, the famous and legendarily faint supernova remnant in Taurus. Also known as Sharpless 2–240, this cloud is composed of expanding gas belched from a dying star that exploded about 40,000 years ago. The nebula is so faint that it’s a challenge to photograph, let alone observe visually. The nebula covers about 3° of sky, making individual parts of it extraordinarily faint. Th...

The Heart Nebula on Valentine’s Day

Posted 10 years ago by David Eicher
Check out this fantastic image from legendary astrophotographer Jack Newton. It shows a well-known region in Cassiopeia that contains two large, faint emission nebulae, IC 1848 (left) and IC 1805. These objects are enormous factories whose gas is coalescing into new stars, producing clusters you can see within the nebulosity. At right, IC 1805 is often called the Heart Nebula (if you tilt your head to the left you’ll see the nebula’s looping “heart” shape). Just to m...

Planning Australia for this year’s big total eclipse?

Posted 10 years ago by David Eicher
OK, a few days ago I told you about Astronomy magazine’s planned trip to see the June transit of Venus in Hawaii. Now I’m going to suggest you also go to Australia to see the big eclipse event of the year, the total solar eclipse on November 14. This will be a nice one, lasting just over four minutes if you’re out at sea in the middle of nowhere, but about 2 minutes near the most populous city in the path, Cairns, Queensland, in northeastern Australia. Once again, Astronomy ma...

Rob Walrecht’s planned super cool superplanisphere

Posted 10 years ago by David Eicher
Even in this electronic age, and even if you observe with a computer screen beside your telescope, you really need at least one old-school device — a planisphere. Sometimes called “star wheels,” these devices allow you to dial in your date and time and see the sky represented for the particular latitude you’re observing from. Many fine planispheres have existed for decades — now Rob Walrecht, the Dutch cartographer and creator of fine star maps, is cr...

Let’s get ourselves a New Horizons-Pluto stamp!

Posted 10 years ago by David Eicher
You may have heard over the past few days of an effort to recognize the New Horizons mission now en route to Pluto and due to arrive in 2015. Yesterday, Alan Stern, the mission’s project scientist, called me and asked Astronomy magazine to step on board as a partner in the effort. Now, many of you know the folks here at Astronomy are Pluto backers. I was a friend of Clyde Tombaugh and considered it a great honor to have known and observed with him quite a few times before his death in 1997...

Come to Hawaii for the transit of Venus!

Posted 10 years ago by David Eicher
The last transit of Venus in our lifetimes will take place Tuesday, June 5, 2012. You can see a portion of this rare and storied event, in which the disk of Venus crosses the face of the Sun, from North America. But Hawaii is one of the closest places where you can see the whole transit — and it’s a pretty nice place to be. I’ll have the privilege of accompanying readers of the magazine on a trip to Hawaii to see the transit this June. In conjunction with Melita Thorpe of...

IBEX illuminates a dark corner of our neighborhood

Posted 10 years ago by David Eicher
Yesterday, scientists at a NASA press conference described the first findings from IBEX, the Interstellar Boundary Explorer satellite, which was launched in 2008 and is the first craft to study the region between our solar system and interstellar space. Astronomers don’t know much about the edge of our solar system and how it interacts with our neighborhood in the galaxy beyond. By contrast, we know a great deal about various objects far away in the Milky Way (and in other galaxies), but t...

How life on Earth made minerals

Posted 10 years ago by David Eicher
For centuries, scientists believed that animals and minerals lived in two separate worlds. Then, four years ago, a groundbreaking study led to a dynamic realization: Life on Earth radically altered the way minerals formed on our planet. Last year, a major research journal devoted an entire issue to analyzing the idea, and now the science of studying minerals and understanding Earth as a planet has been radically shaken up. The evidence shows that microbes on Earth exploded the number of mineral...

Amazing new picture of where you live

Posted 10 years ago by David Eicher
In the old days at Astronomy, we used to have a saying whenever someone separated Earth science from astronomy— “Earth is a planet, too.” NASA has just released what may be the greatest image yet of our planet, a multicolor photo of Earth showing North and South America and swirls of clouds hovering about. This “blue marble” image of the planet was made with the VIIRS instrument aboard NASA’s most recent Earth-observing satellite, Suomi NPP. Th...
