This gorgeous and unusual aurora display was captured by Brendan Alexander from the North Coast of Donegal, Ireland. “We were treated to an absolutely stunning aurora display on the morning of the 24th of April 2012,” Brendan wrote on our Flickr page. “Easily the best I have seen in my eventful four years of sky watching. The display started off strong at nightfall (22:00 UT) with intense and almost static rays. However shortly after magnetic midnight the aurora came to life, complete with waving curtains, shimmering rays, vivid colours and pulsating heart. A spellbinding and enrolling time was endured from dusk to dawn. A Stunning display to remember during the bright summer months ahead.”

Brendan used a Canon 1000D camera with a Sigma 20mm F1.8 lens. Exposure: 8 – 11 sec ISO 1600

What a great view of Markarian’s Chain! Amateur astronomer Richard Richins took this image with a 300mm Canon f/4 lens (mounted to a Canon T2i). Look closely, as Richard says there are well over 100 galaxies in this image! Click the image for a larger, better view of Markarian’s Chain, which is a stretch of galaxies in the Virgo Cluster. It is called a chain because, when viewed from Earth, the galaxies appear almost linked together in a curved line. It was named after the Armenian astrophysicist, B. E. Markarian, who discovered their common motion in the early 1960s. Some of the galaxies seen here include M84 (NGC 4374), M86 (NGC 4406), NGC 4477, NGC 4473, NGC 4461, NGC 4458, NGC 4438 and NGC 4435. How many can you find?

Thanks to Richard for sharing his image with Universe Today. See more of his work at his website, Enchanted Skies.

Now is the time to take a look at the planet Saturn, as the ringed planet will be at opposition this weekend, making its closest approach to Earth on April 15, 2012. Its face will be fully illuminated by the Sun, so get out those telescopes, binoculars and your imaging equipment! We want to see your photos! Efrain Morales from the Jaicoa Observatory took this image of Saturn and some of its moons on April 3.

The giant planet’s rings are now optimally angled at over 13 degrees, revealing them better than they have appeared in the past five years. To see the rings of Saturn during opposition, in the northern hemisphere point your telescopes east to southeast at nightfall and south around midnight. For reference, Saturn will be near the bright star Spica, in the constellation Virgo. In the southern hemisphere, Saturn will be above the eastern horizon at 10pm local time, still near Spica.

If the skies aren’t clear in your area, the Slooh Space Observatory will broadcast a free, real-time feed of Saturn at opposition. Their coverage will begin on Sunday, April 15th, starting at 6:30 p.m. PDT/9:30 p.m. EDT/01:30 UTC (April 16th). Slooh will provide two distinct observatory feeds — one from a remote location in South Africa and the second from their world-class observatory site in Canary Islands off the coast of Africa. The broadcast can be accessed at Slooh’s homepage or by visiting Slooh’s Google+ page, where you will be able to see a panel of experts interact live via G+ Hangouts On Air.

The experts include Duncan Copp, producer of many astronomical documentaries, including “In the Shadow of the Moon”; Amanda Hendrix, Cassini’s deputy project scientist from NASA’s Jet Propulsion Laboratory; and Bob Berman, author of numerous astronomy books and contributing editor and monthly columnist for Astronomy Magazine.

“In 40 years of observing the heavens and watching people’s reactions to celestial glories, I’ve found that no object elicits more amazement and sheer wonder than Saturn. I am thrilled to be part of Slooh’s live close-up visit to that magnificent planet,” said Bob Berman.

Alqueva: Some of the Darkest, Clearest Skies on Earth

It’s a place with dark skies, clear nights and ancient astronomical megaliths. What more could you want in an astro-destination? The Great Lake Alqueva Dark Sky Reserve in Portugal is the first site in the world to receive the “Starlight Tourism Destination” certification and has good atmospheric conditions for stargazing for more than 250 nights of the year, as well as having special lodging just for astro-tourists. The services for guests include late night meals and meals to go for stargazers, available telescopes and binoculars, and classes on astronomy and observing.

Astrophotographer Miguel Claro was tasked with having just two nights to take images of one part of this Dark Sky Reserve to help promote the region, and he has sent Universe Today his stunning images. “They are representative of the Monsaraz region, one of the locations covered by the Dark Sky Reserve area and that had the best dark sky measures in the process of Starlight validation,” Claro told UT. “Even being so dark, and without the presence of the Moon to light up the landscape – at this time of the year without the major presence Milky Way – I had to use very high ISO´s, so there were some differences between heaven and Earth elements, avoiding overly dark images. But the sky was so dark, that we could find M33 with unaided eye.”

The Alqueva Dark Sky Reserve is coordinated by Genuineland in partnership with the Tourism Lands of the Great Lake Alqueva, the Alentejo Coordination and Regional Development Commission and EDIA, SA and with the collaboration of APAA – Portuguese Association of Amateurs Astronomers- through Dr. Guilherme de Almeida and Eng. Vitor Quinta, as well with external participation of Dr. Raul Lima, for the sky measurements that were made during the certification process.

Recognize this? Yes, it is our own Moon, but using Photoshop, the photographer, César Cantú from the Chilidog Observatory in Monterrey, Mexico extracted the Moon’s colors and exaggerated them just a bit. “Although exaggerated, the color components are the real highlights,” César said, “with blue indicating a significant amount of titanium, and the orange areas with little iron or titanium. These colorful images are more easy to perform That thanks to digital cameras that detect colors — where with analog cameras, it is still impossible.”

César took the image on April 6, 2012. See his website for more details.

Planetary Conjunction Mashup

A triple conjunction between 3 different objects: Venus, The Pleiades and an airplane!! Taken on the 4th Apr 2012, 12:15UT. Credit: Shahrin Ahmad

A Boulder Side of Venus – Conjunctions 2012 from Patrick Cullis on Vimeo.

So far, 2012 has brought us a plethora of planetary conjunctions, with Venus pairing with the Moon, Jupiter and the Pleiades. Not all at the same time, of course, but photographer Patrick Cullis has put them all together in this wonderful timelapse mashup video, which includes the beautiful foreground of the Flatirons of Boulder, CO. “Jupiter and Venus dominated the early days of March, coming within 3 degrees of one another,” writes Patrick. “Then, Venus passed a crescent moon on its way to a meeting with the Seven Sisters, also known as the Pleiades.”

And we’re all waiting for this year’s big conjunction on June 5 or 6, 2012, depending on your location, then the tiny disk of Venus will glide across the face of the Sun. That won’t happen again until 2117.

To complete our conjunction mashup, we’ve got a really unique image, below, of a triple conjunction between 3 different objects, Venus, The Pleiades and an airplane taken on April 4, sent to us by Shahrin Ahmad in Malaysia, PLUS, a wonderful new poem by space’s poet laureate, Stuart Atkinson, about his experiences viewing the recent conjunctions. It’s a must read for any amateur astronomer, putting to words the joys — and disappointments — of lifting your eyes to the heavens!

CONJUNCTION

By Stuart Atkinson

For weeks I watched them drift towards each other,
Approaching shyly, slyly; two would-be lovers
From a Jane Austen dance, casting furtive glances
Across the ballroom of the golden twilight,
Eyes for no-one else as nightfall drew near.
Venus – lovely and lantern-bright, out-shining
Every other dancer on the floor; Jupiter – fainter
By far but still beaming with a noble light,
Stalking his pretty planetary prey…

The first time I saw them they were still
A third-of-the-sky apart,
But each blazing Turner sunset brought them closer yet,
Each day’s end a little better-placed to gaze
Upon each other’s radiant face,
And a million Earthbound eyes looked on, amazed
To see two such fine celestial jewels
Coming together in the sky.
Some sought out a sheltered, grassy place
Of peace and dark to watch the twin sparks’
Close approach in groups; others stood alone
In overgrown gardens or on concrete roofs,
Marvelling at the view from their light-polluted
Homes, wondering what they would see if only
They could escape the Bright and find a place
Without the blinding security lights’ flares
And streetlights’ orange glare…

Of course, I missed the breathless climax
Of their brief encounter. For half a dozen days
Either side of that ringed-in-red date
My sky was thick with cloud fat and foul,
A star- and planet-hiding shroud draped o’er
The Auld Grey Town that was not pulled away
Until the planet parade had passed by,
And the next time I looked to the west
The best view had come and gone:
Unseen by me, Venus and Jupiter had chastely
Touched fingers then parted, leaving
The lovesick gas giant fading, falling
Forlornly towards the rooftops and trees
While the Goddess of Love soared higher,
Growing ever-brighter as she climbed…

Cheated? Yes. But I have fine memories
Of some magical nights, and a hundred photographs,
Taken from the shores of moonlit, duck-dotted lakes
And crumbling castle walls. Sometimes in company,
More usually alone I stood and watched those distant
Worlds waltzing across the western sky,
My so-often-now world weary eyes
Suddenly wide again with wonder at the beauty of it all,
Listening to them calling “Look at us! See
How gloriously we shine above your sleepy little town…!”

…Far apart now, their dusky dalliance a thing of the past,
Venus and Jupiter are just bright stars once more;
The night sky’s restless showbiz spotlight has swept on,
Picking out Saturn, Mars and a waning Moon,
The Great Conjunction relegated
To Celestial Celebrity Has Been history.

Which is how it should be.

The Earth turns, and turns, and turns, setting a universe
Of stars and planets wheeling around pale Polaris,
Lovely and sentinel-still,
While the Milky Way floats serenely
Through her snow-globe of glitter-flake galaxies,
The prickling breeze of a billion billion suns’ solar winds
Blowing on the faces of the few evolved apes
Brave enough to lift their eyes from the grey
Landscapes of their everyday lives and catch
A fleeting glimpse of beauty in the Great Beyond…

Astrophotos from Around the World of the Venus-Pleiades Conjunction

The past several evenings, Venus has been snuggling up to one of the most famous star clusters, the Pleiades. Universe Today readers have taken some beautiful images of that event, and they have generously shared them with us. Above is John Chumack’s stunning view from Ohio in the US; see below for more images from around the world!

The Pleiades, also known at the Seven Sisters, is a beautiful bright blue open star cluster 440 light years from Earth. Only once every eight years does this conjunction take place.

John Anton took this pretty image from New Jersey in the US. “It was a beautiful sight,” he said.

Astronomers say that the relative tightness of the cluster indicates this is a young group of stars, and the member stars were formed about 100 million years ago and will probably travel together through space as a bound cluster for another 250 million years before the gravity of the Milky Way breaks up the cluster into individual field stars.

Last night (March 25, 2012), Jupiter, Venus and the Moon put on quite a show, and Rick Ellis from Toronto, Canada captured it — over two dozen times. This composite image was created from 31 frames taken five minutes apart, each with an exposure time of 5 seconds. Thanks to Rick for creating this image “just for the gang at UT.” Check out his earlier image of the Venus-Jupiter conjunction from March 13

[/caption]

Astrophotographer César Cantú from the Chilidog Observatory in Monterrey, Mexico calls this image “Pulp Fiction” for its violent areas of hot, deadly gases being expelled by the young stars, solar windstorms, huge accumulations of cosmic dust. But the two features show here are actually are named after things much more peaceful in nature: The Cone Nebula and the Christmas Tree Cluster. This open cluster of stars was discovered by William Herschel in 1785 and is cataloged as NGC 2264 and lies at a distance of 2,600 light years from our solar system.

“This is an H II region located in the constellation Monoceros,” César says, “a region with much stardust. The picture shows also the Hubble Variable Nebula, like a little flash at the top right. This is a vast field reached with the telescope and focal reducer FSQ106, which gives a focal length of 385mm with great resolution. The camera used was the FLI8300, with 4:30 hours of exposure.”
