Here’s an unusual if not stunning way to look at the Sun: César Cantu from the Chilidog Observatory in Mexico has taken a few images of the Sun, and reversed the colors, or made a negative. This increases the contrast and allows structures to be seen — or at least stand out — that otherwise are not visible.
“The picture is made under normal procedure,” César tells us. He creates an Avi file, then reverses the colors, and also applies false color, leaving the sky to look blue and the Sun to yellow-orange and the chromosphere as red. “This is to delight the author!” César says.
The solar prominences, in all sorts of shapes and sizes, really stand out.
Below, you can see a comparison of “normal” image which has then been “negativised.”

The STS-135 crew of space shuttle Atlantis and the Expedition 28 crew of the International Space Station were treated with great views of the Aurora Australis. Here’s one shot the crews photographed, showing a panoramic view of the station/shuttle complex along with several different astronomical beauties! The aurora shows up brightly, but what else is in the image? Looking closely –and southern hemisphere observers might recognize some objects better — but do you see the globular cluster Omega Centauri, the Coalsack Nebula and the Southern Cross? Anyone see anything else?
See below for another great aurora shot from the ISS, where the green glow shows up even better:

These images were taken on Thursday during one of the “night” passes for the station/shuttle. The astronauts mentioned the aurora during media interviews on Friday. “We saw an incredible Southern Lights aurora,” said STS-135 pilot Doug Hurley. “It was the best one I’ve seen in my two spaceflights. It was just unbelievable, the view out the cupola.”

Mysterious “night shining” or Noctilucent Clouds are beautiful to behold, and here are some gorgeous examples what skywatchers in the UK have been experiencing. Stu Atkinson took this stunning panoramic view from Kendal Castle. (Click image for access to a larger version). NLCs are usually seen during the summertime, appearing at sunset. They are thin, wavy ice clouds that form at very high altitudes and reflect sunlight long after the Sun has dropped below the horizon. Scientists don’t know exactly why they form, and they seem to be appearing more and more in recent times.
See more below.
Science writer Will Gater also had a great view of NLCs this morning. Click the image to see his animation, or see more of his images and animations at his website post.

Noctilucent Clouds are finally here! Well, at least they were for me at about 3:00am on the 29th of June.
I have heard that there have been some sightings, but for me, this mornings display heralds the new NLC season – a month later than usual?
Conditions were amazingly warm, and the night was still and magical as I looked northwards from my home in West Berkshire UK. I couldn’t help but notice a burning bright star almost due North and quite low, Capella in the constellation of Auriga! This is when I spotted the first faint wisps of noctilucent cloud.
Capella isn’t always in the North, but it is this time of year and it usually makes a guest appearance during morning noctilucent cloud displays.
Noctilucent clouds are very rare and tenuous clouds on the edge of space and occur at altitudes of around 76 to 85 kilometers (47 to 53 miles).
They are only seen when conditions are just right (still not fully understood) after sunset or before sunrise. They are illuminated by the sun, which is still way below the horizon from the observers location. Due to their very delicate nature, noctilucent clouds can only be seen at these times.

Astrophotography is one thing we can’t get enough of here on Universe Today and some of the best amateur astronomy images can be found at the Astronomy Photographer of the Year competition. Interested in entering? There’s just over a month to go until the Royal Observatory in Greenwich’s annual contest closes. If you have taken some astrophotos this year, why not enter? You’ll need to submit any entries by 13 July, 2011 for a chance of winning what has become a prestigious award for amateur astronomers.
The prizes include a top prize of £1,500 and pride of place in the exhibition of photos which opens at the ROG in September. I was fortunate to be on hand for the award ceremony in 2010, and it was a wonderful event. Each entrant can submit up to five images to the competition and some truly breathtaking photos can already be seen on the official Flickr page for the competition.
There are four main categories you can enter: Earth & Space, Our Solar System, Deep Space and Young Astronomy Photographer of The Year. And this year there are also three special awards – one for newcomers, another for shots that creatively capture people and space, and a third for images that have been taken by robotic/remote telescopes and that have been processed by you.
Photographers can enter online by visiting www.nmm.ac.uk/astrophoto, where full competition rules and some top tips on photographing everything from star trails to deep space objects are also available.
The panel of judges includes Sir Patrick Moore and the ROG’s Public Astronomer Dr. Marek Kukula. The winners will be announced at an awards ceremony on the 8 September, and an exhibition of the winning images will open to the public at the Royal Observatory the following day.
Good luck, and we hope to be posting YOUR winning image here on Universe Today!

We’ve featured many space images here on Universe Today that have been produced by imaging enthusiasts who take raw images from a mission or spacecraft and refine them into what many consider works of art. Michael Benson has taken this activity to a level “above and beyond” by creating exhibits, books, and movies portraying the images taken by our robotic emissaries to the solar system.
“Travelers hurrying through Concourse C of Dulles International Airport in Washington, DC may be in danger of missing their flight because of a stunning and attention-grabbing exhibit of Benson’s work in the walkway there,” said Bob Hirshon from the American Association for the Advancement for Science (AAAS), who interviewed Benson on today’s 365 Days of Astronomy podcast. Above is an example of Benson’s work, a Voyager image of Europa hovering in front of a tempestuous Jupiter.
Since 1995 Benson, through his company Kinetikon, has produced a series of books, exhibitions, films, and photographic prints which explore the intersection of art and ideology and feature planetary landscapes and galactic vistas.
“Experiencing Benson’s work, you get the feeling that it comprises a kind of travel log—the way Anselm Adams’ photos give you a sense of the photographer visiting exotic locales and waiting patiently for the light and shadows to hit exactly right before snapping his photo,” said Hirshon, artistically describing Benson’s images. “But of course, Benson can’t really visit his locations.”
Benson said this type of work is not hard, but it’s not easy either. For example, the image above is created from about 60 raw frames assembled by Benson over a period of months. “I would like to think that that picture will kind of take its place as a key image in the history of exploration, because it’s such an extraordinary image,” Benson said.
Some other examples of Benson’s work:

Of this Cassini image of Saturn, Benson said: “The only way to really see it in its full glory is to do the image processing. And when I put that picture together, I felt extraordinarily privileged, you know because I realized that I was probably the first human being to see it in color, the way it would be seen if we were there, because I doubt any planetary scientist went into that data and did what I did, it took about two days of work. And so I had this feeling of privilege, almost like I was exploring space myself, to see that extraordinary thing.”

Benson’s next project is a book with a working title of “Planetfall,” featuring solar system images taken since the turn of the century, a period of exploration that humankind has never experienced before.

What do astronauts do when they aren’t in space? Commercial photographer Hunter Freeman’s images all seem to have a bit of whimsy included, and his series of suited astronauts doing everyday things us regular humans may find humdrum will bring a smile to your face, guaranteed. Make sure you look for the small, very relevant details! Check out the entire series at this link, and learn more about his work at his website.

This stunning new image of the Orion Nebula has a bit of salsa to it! César Cantú of the Chiledog Observatory in Monterrey, Mexico took this image earlier this month. But he had to travel to Paredón, Coah in Mexico to escape the fog to get this great image. Here are the specs: Orion Atlas mount, 90mm Astrotech APO telescope camera; LRGB QSI540, 3 hours with 600 seconds subs. But the fog tried to follow, César told us. “The intention was 4 hours, but the fog did not allow it,” he said. See more of his great images at this website, Astronomía Y Astrofotografía.
Photographer Terje Sorgjerd spent a week capturing what he called “one of the biggest aurora borealis shows in recent years,” and the results are simply stunning. The footage was shot in and around Kirkenes and Pas National Park in the very north part of Norway, which borders Russia, at 70 degree north and 30 degrees east. Temperatures were around -25 Celsius, Sorgjerd said.

How super was your full Moon on March 19, 2011? I was completely clouded out, but thankfully quite a few people have been kind enough to share their images. Here are a pictures sent in by readers, as well as via Twitter and Facebook. We’ve got images from all around the world, and even though the size of the Moon really wasn’t that much bigger than usual, (read here why not) it is great to see so many people getting out and looking up at the sky! Our lead image comes from Rasid Tugral in Ankara, Turkey.

This gorgeous shot, was sent in by Donna Oliver from western Australia, take a bit of creative license. She says: “The goal was not to shoot the moon as such but to take advantage of the additional light. Obviously on a long exposure, the moon would not look this good, so I shot the moon, then added it. You can see star movement if you look carefully. I made the moon extra large as my interpretation of the Super Moon.”

Check out these two from Tavi Greiner on her blog, A Sky Full of Stars: In this one, the Moon rises over a boat on the Shallotte River, just a few hundred yards from the Atlantic Ocean.
And in this one, the Moon appears captured by the rigging, and even almost appears to have lit the ropes on fire.
