Wow! See the ‘International Earth & Sky Photo Contest’ Winners

A montage of Earth & Sky International Photo Contest winners, courtesy of TWAN.

Need a little eye candy? Look no further! Here are the latest winners of the International Earth and Sky Photo Contest. This was the 5th annual contest, which is organized by The World at Night (TWAN), the National Optical Astronomy Observatory, and Global Astronomy Month from Astronomers Without Borders. This contest stresses the importance and awareness of dark skies, look for images that portray the “TWAN style” —showing both the Earth and the sky—by combining elements of the night sky set in the backdrop of the Earth horizon, often with a notable scenery or landmark.

The 2014 contest had two categories: “Beauty of The Night Sky” and “Against The Lights.”

“Both contest categories provide a visual awareness of the disappearing starry night sky and hopefully an understanding as to its cause,”said contest judge Connie Walker, associate scientist and education specialist at the National Optical Astronomy Observatory. “The added hope is that the photos will provide an incentive to be more actively involved in reasonable light pollution solutions and therefore dark skies preservation.”

The first prize in Beauty of the Night Sky category was awarded to Luc Perrot from Réunion Island of France (southern Indian Ocean), for his image “Over the Top,” below, shot on Feb 28, 2014. A volcano in the Reunion Island peaks out of a sea of clouds and rests under stars.

“The photograph beautifully captures a scene that is eternal, the central bulge of the Milky Way is rising majestically over Piton de la Fournaise volcano,” said contest judge David Malin, who is widely known as a pioneer in scientific astrophotography “The image shows no sign of human presence, and is a reminder that the foreground landscape and the dark dust lanes in the Milky Way are made of the same elements, seen here as delicate clouds and solid mountain peaks.”

6097-4

Here are the “Beauty of the Night Sky” top winners:

1- Luc Perrot, Reunion Island (France)
2- Ben Coffman, USA
3- Nicholas Roemmelt, Austria
4- Ibrahim Elawadi, Egypt
5- Phil Hart, Australia

We loved this image, below, from Nicholas Roemmelt of Austria for his outstanding capture of aurora over Kirkjufell waterfalls in Iceland in a moonlit night of March 2014, titled “Kirkjufell Nights” which won third place in the “Beauty of the Night” category.

Contest judge and long-time National Geographic photographer James Richardson regards this image “a fantastic confluence of the forces of nature. This is, of course, just one small corner of our universe, and yet we see swirling all the waterfalls carving at the rocky landscape, the mountain resisting erosion, the aurora sweeping around the pole and the stars beyond, part of the whole. The organizational power of this photograph is just wonderful.”

6097-7

The first prize in “Against the Lights category” (and the overall contest winner) goes to Giorgia Hofer of Italy for his photo “Light in the Sky” taken on January 1, 2014 from Cibiana Pass in the Dolomites (Alps), northern Italy.

“I tried to portray the mist produced by the drones launched fireworks on the evening of new that were illuminated by a nearby light tower. in the only dark part of the sky the Big Dipper (the prominent part of constellation Ursa Major) is perfectly framed by the rays,” said the photographer.

Contest judge James Richardson said of this photo, “This captures the great ambiguity we feel about the night and night lighting. It is at once beautiful and beautifully composed. But it is also night lighting obscuring the beauties of the night. A beautiful image that confronts us with our own, conflicted desires.”

6097-3

The entire “Against the Lights” winners are:
1- Giorgia Hofer, Italy
2- Alex Conu, Romania
3- Majid Ghohrudi, Iran
4- Mark Gee, New Zealand
5- Song Hongxiao, China

We also loved the fifth place winner in the “Against the Lights” category. “Heavenly Street” by Song Hongxiao of China is a long-exposure photo sequence of March 30, 2013 that captures star trails from the sacred Taishan or Mount Tai. Says the photographer: “Its been an ancient China tradition that people climb to the top of Mountain Tai to watch the beautiful sunrise and pray. In this picture thousands of people are walking across the Heavenly Street. The lights from their flashlight interplays with the stars in the sky.”

6097-12

There are also 70 images as honorable mention which you can see in the video below, or in the contest Guest Gallery. The images were submitted (or taken) from 55 countries and territories.

We feature A LOT of astrophotos here on Universe Today, and we get many comments about them, too — with some people saying they could NEVER take photos of the night sky because they live in cities, or are too close to street or yard lights or other causes of light pollution.

Now, award-winning astrophotographer Justin Ng from Singapore has created a tutorial for how to photograph the night sky, even in light-polluted area.

“This tutorial shows you how I photograph the Milky Way that’s obscured by the extreme light pollution in Singapore, using photography equipments that you may already have and a workflow that probably works on most versions of Photoshop,” Justin writes, adding that the type of photo processing he uses in Photoshop can be achieved without purchasing additional plugins.

Justin says that taking pictures of the night sky is a way you can “do your part to promote public awareness of astronomy and the importance of preserving the beauty of our night skies through your images. And I am going to show you how you can do just that using photography equipment that you may already have and a workflow that probably works in most versions of Photoshop.”

For this tutorial, you will need some previous knowledge about basic photography and post-processing.

You can access the full tutorial here on Justin’s website.

UPDATE: Thanks to several people on Twitter who pointed out that what is seen in the footage here is the the upper stage of the Falcon 9, the Dragon capsule, and the ejected solar panel covers moving along together in orbit around the Earth. And as Phil Plait pointed out, since this was taken a few minutes after the capsule separated from the rocket upper stage, all the individual things you see here were still near each other in space.

We need to say it: astrophotographer Thierry Legault has done it again! Here’s an absolutely fantastic capture of the SpaceX Dragon capsule just 25 minutes after it launched from Cape Canaveral Air Force Station, as it passed over Europe. Here, Legault captured footage of Dragon crossing the Big Dipper as seen from Paris at 19:50 UTC, April 18, 2014.

“It was an incredible vision: 4 bright dots moving together!” Legault told Universe Today via email.

Check out more of his amazing astrophotography and even some of his tips and tricks at Thierry’s website.

Get more information and find all the rules here.

contest 2

A second photo contest comes from our friends at TWAN—The World At Night with their 5th annual International Earth and Sky Photo Contest, which is part of Global Astronomy Month in April 2014. The TWAN the contest is open to anyone of any age, anywhere around the world.

This year’s contest theme, “Dark Skies Importance,” has two categories: “Beauty of the Night Sky” and “Against the Lights.” Photos submitted to the contest should address either category: either to impress people on how important and amazing the starry sky is or to impress people on how bad the problem of light pollution has become. Both categories illustrate how light pollution affects our lives. Photographers can submit images to one or both categories.

Submitted photographs must be created in the “TWAN style” — showing both the Earth and the sky — by combining elements of the night sky (e.g., stars, planets, the Moon or celestial events) in the backdrop of a beautiful, historic, or notable location or landmark. This style of photography is called “landscape astrophotography”. This is similar to general “Nightscape Photography” but with more attention to the sky, astronomical perspectives, and celestial phenomena.

Watch Saturn Slip Behind the Moon

Occultation of Saturn on Feb. 22, 2014 by Colin Legg

Or, more accurately, watch the Moon pass in front of Saturn. Either way you get the same result: a beautiful video of planetary motion in action!

On the morning of Saturday, Feb. 22, the Moon drifted in front of the planet Saturn from the point of view of certain locations on Earth. Luckily one of those locations was Perth, Australia, where astrophotographer Colin Legg happens to be, and thus we all get to enjoy the fantastic results of his photographic and astronomical acumen.

Check out the video below:

The occultation — as such events are called whenever one celestial object passes in front of, or “hides,” another (the root of the word means “to conceal”) — may make it look like a tiny Saturn is getting absorbed by a giant Moon. But (obviously) they are separated by a vast distance: at the time of the occultation, 9.658 AU, or about 1,444,816,000 kilometers (897.7 million miles).

These sort of events will become a bit more common as the Moon is “headed towards a ‘shallow’ year in 2015 relative to the ecliptic; it will then begin to slowly open back up and ride high around 2025,” according to a recent Universe Today article by David Dickinson.

For those of you interested, Colin lists his equipment as a Celestron C8, f/10, prime focus. His camera is a Canon 5D2, running Magic Lantern RAW video firmware in 3x crop mode @ 1880 x 1056 resolution. Footage was taken at 1/60 sec exposure, ISO 200, 10 fps.

An Amazing Capture of Jupiter and its Moons

It’s always a thrill to watch the action at Jupiter, as its moons pass in front of and behind the gas giant planet. We wrote recently about this month’s opposition of Jove on January 5th, marking the start of the Jupiter evening viewing season for 2014. 

Astrophotographer Michael A. Philips also recently undertook a challenging series of sequences of Jupiter and its moons Io and Ganymede, with stunning results. You can see the motion of Jupiter’s rotation, the Great Red Spot and even a bit of cloud swirl as Io disappears behind Jupiter and Ganymede begins to transit in front and cast a shadow back onto the Jovian cloud tops.

Concerning the capture, Michael wrote on his blog:

“This night was a lucky night. I had not looked at the weather forecast enough to know if it would be good or not. Cold temps aside, I decided earlier in the day to set up and go out with the 14” f/4.5 scope named Akule. As an added bonus, Mitchell Duke tipped me off to a transit of the Jovian moon, Ganymede.”

Note that Jupiter and its moons are currently casting their shadows nearly straight back from our perspective. Expect that to change, however, in the coming months,as Jupiter heads towards eastern dusk quadrature on April 1st and we see the action from a sideways angle. Watch the video in full screen mode and you’ll note that Mike captured some detail on the surface of Ganymede as well! Generally, at the eyepiece, the moons of Jupiter disappear entirely due to low contrast against the bulk of the planet, with only the black dot of the shadow seen… this video capture gives the ingress of Ganymede at the start of the transit a great 3-D appearance.

Webcam imaging of planets has really taken off in the past decade, with backyard astronomers now routinely capturing images that far surpass professional and textbook images from just a decade prior. Great images can be taken using nothing more than a telescope, a laptop, free image stacking software such as Registax, and a webcam converted to fit into an eyepiece holder… you may find that you’ve got the gear sitting around to image Jupiter, tonight.

Mr. Phillips rig, however, is a little more advanced. He notes in the description of the video that he’s using a Flea3 camera from PointGrey Research with a 5x Barlow lens yielding a 9200mm focal length. He’s also shooting at 120 frames per second, and taking successive red, green and blue images for 30 seconds. Finally, a derotation of Jupiter – yes, it really rotates that quickly, even in a short sequence – is accomplished using a sophisticated program named WINJupos.

Video stacking gives processors the ability to “freeze” and nab the best moments of seeing from thousands of frames. Some imagers hand select frames one by one, though many programs, such as Registax, use algorithms to nab the best frames from a preselected percentage of the total shot.

Local seeing conditions also play a key role in image capturing.

“I moved far away from the house as possible, and I think that helped some,” Michael noted. “I also started cooling the spit out of the mirror, aggressively. Even when cooled for a few hours in the winter, the heat in the Pyrex mirror comes back. I think there’s a small heat engine inside the beast!”

For best results, imagers tend to go after planets when they’re at their highest in the sky, and viewed through the least amount of turbulent atmosphere. This is when a planet is transiting the local north to south meridian, and when it’s at opposition, which Jupiter is this month. At opposition, a planet transits at local midnight. The same goes for the best opportunities for visual observing as well.

Shadow transits of Jupiter’s moons are also just plain fun to watch. In an often unchanging universe, they offer a chance to see something unfolding in real time. Jupiter has the fastest rotation of any planet at 9.9 hours, and the large Galilean moons of Io, Europa, Ganymede and Callisto are tidally locked in their rotation, keeping one hemisphere permanently turned towards Jupiter like the Moon does orbiting the Earth. The inner three moons also keep a 1:2:4 orbital resonance, assuring you’ll never see more than three of the four Galilean moons transiting from your line of sight at once. You can see two of the inner three moons, plus Callisto in transit, but never all four at the same time! A triple transit last occurred on October 12th, 2013, and will next occur for observers in eastern Europe and Africa this year on June 3rd.

We’re also currently in the midst of a series of shadow transits for the outermost Galilean moon Callisto, which end in July 2016. Can you identify the different moons by the size and hue of shadows they cast? Sky & Telescope publishes a great table for the ingress and egress of Jupiter’s moons. You can also check them out using the freeware program Stellarium.

Can’t wait that long? A double shadow transit involving Europa and Callisto occurs in just a few weeks for western North America from 10:20 UT-12:44UT on the morning of February 6th, a chance for another stunning animation sequence…

Congrats to Michael Phillips on a great capture!

Announcing a New Comet ISON Photo Contest!

Universe Today is proud to announce that we are partnering with OPT Telescopes and SpaceWeather.com for a brand new Comet ISON Photo Contest, with over $10,000 in prizes to give away!

Comet ISON is one of the most anticipated sky events for years, and already astrophotographers have been busy trying to capture images of this comet. But as it gets closer to the Sun, hopefully it will become even brighter and visible to more people – not just the astrophotographers with the really great equipment!

This new photo contest features several different chances to win some great prizes, thanks to OPT Telescopes, the folks behind this contest. There will be a popular vote on Facebook with winners of first, second and third places, as well as images judged by a panel of experts with three winners in that category as well.

And so its not just about having great equipment.  “It’s about the overall image and it can be in any ‘style’ at all,” says OPT Telescopes. “We’ve seen some amazing submissions shot with DSLR’s and point and shoot digital cameras in the past, and encourage everyone, regardless of skill level or equipment owned, to participate.”

Who can participate? Anyone aged 13 years and older who has a valid email address.  (Employees of OPT, Universe Today and Spaceweather.com are not eligible for entry.) Images must be the original work of the contestant.

This Aurora Video Shows How High The Lights Were Whizzing

Ever stood outside looking at the aurora and felt as though it was swirling just a short distance above your head? It’s hard to judge altitude when looking at sky phenomena because there are few landmarks above us. (The moon effect at the horizon is an example.) But it turns out there is a way to measure aurora altitude.

The eerie, green glow of the Northern Lights swirls about in the video you see above. A group of researchers used a unique but simple technique to measure how high the electrons were during the dazzling light display: they mounted two digital SLRs eight kilometers (five miles) apart in Alaska, and used that old astronomical friend, parallax, to measure distances.

“Using the parallax of the left-eye and the right-eye images, we can calculate the distance to the aurora using a [triangulation] method that is similar to the way the human brain comprehends the distance to an object,” stated Ryuho Kataoka, an associate professor at the National Institute of Polar Research in Japan. “Parallax is the difference in the apparent position of an object when observed at different angles.”

Altitude measurements have been done before using this technique, but it’s the first time digital SLRs were employed, the research team said. A typical aurora has electrons that are between 90 kilometers and 400 kilometers (55 miles and 249 miles) high.

By the way, for all the amateur astronomy photographers, there’s a potential chance for you to get involved with future research activities.

“Commercially available GPS units for digital SLR cameras have become popular and relatively inexpensive, and it is easy and very useful for photographers to record the accurate time and position in photographic files,” said Kataoka. “I am thinking of developing a website with a submission system to collect many interesting photographs from night-sky photographers over the world via the Internet.”

Submissions Needed for Saturn Mosaic Project

For all our astrophotographer friends out there: If you haven’t heard about the Saturn Mosaic Project, you’ll want to take note of this. In cooperation with Astronomers Without Borders, the special project for the recent Cassini image of planet Earth, called The Day The Earth Smiled (TDTES) is sponsoring a Saturn Mosaic project, where you can submit an image you’ve taken of Saturn. Those received will be compiled into a mosaic that will look like image that Cassini took on July 19, showing Earth just below Saturn’s rings (see below). But when you zoom in you’ll see all the pictures from Earth that the mosaic is made of.

I received a note from AWB President Mike Simmons saying they need more submissions, and the deadline for submitting a photo has been extended to July 29, 2013.

“I know a lot more people will want to be a part of this if they know about it,” Mike said via email. “It’s something to tide everyone over and keep the buzz going while we wait for the final mosaic from Cassini.”

But you don’t have to be a seasoned astrophotographer to take part in the Saturn Mosaic. The image you submit doesn’t have to be one taken with a large telescope – just take a picture of Saturn as a “star” in the sky with an ordinary camera, capturing your surroundings as well. Or it could be an image you took earlier this year.

“There are other kinds of photos that anyone can submit that don’t even requiring imaging the sky,” Simmons added. “We didn’t want to limit this to only those with the ability and weather to image Saturn itself.  Photos of outreach events or people waving at Saturn from JPL’s Wave at Saturn are good, too.  Or just a portrait taken with the Lord of the Rings — a live view projected from a telescope or even a photo.  Like a couple getting married at the time Cassini was taking their photo (and everyone else’s) posed with Saturn.  I took the easy way and took a shot of me and Saturn in my office.”

These can be taken any time, so people can still take a shot and get into the mosaic (the image does need to have been taken in 2013, however.)

“It’s all about sharing and commemorating the excitement of the moment when the photo was taken, and the anticipation of the release of Cassini’s historic photos,” Simmons said.  “Like all Astronomers Without Borders project, it’s open to everyone on Earth.  And beyond.”

For a slide show of some of the great shots people have submitted so far, visit the Saturn Mosaic Project page to see things like Saturn with a T-Rex, outreach in Iran, kids drawings of Saturn in Ghana, and more.

Simmons said The World at Night will create the final mosaic, which is expected to be online and ready to view and zoom in on by August 4 or earlier.

So take your best shot and be a part of the mosaic! Find out more on the Astronomers Without Borders website.

Zodiacal Light Over ESO’s La Silla Observatory

We don’t put much stock in astrology or horoscopes here at Universe Today, but there’s one thing related to the zodiac that’s all science and no superstition: zodiacal light, captured here in a gorgeous photo by astronomer Alan Fitzsimmons above ESO’s La Silla Observatory.

Created by sunlight reflected off fine particles of dust concentrated inside the plane of the Solar System, zodiacal light appears as a diffuse, hazy band of light visible in dark skies stretching away from a recently-set Sun (or before the Sun is about to rise).

The Moon is located just outside the frame of this picture, bathing the observatory in an eerie light that is reflected off the clouds below.

The La Silla Observatory is located at the outskirts of the Chilean Atacama Desert at an altitude of 2400 meters (7,900 feet). Like other observatories in this area, La Silla is located far from sources of light pollution and, like ESO’s Paranal Observatory, it has some of the darkest night skies on the Earth.

The dome in the foreground, just to the right, is the Swiss 1.2-metre Leonhard Euler Telescope named in honor of the famous Swiss mathematician Leonhard Euler (1707–83).
