Double Helixes Streak Across the Sky in Multi-Shot Images of Birds by Xavi Bou

October 25, 2018

Kate Sierzputowski

Spanish photographer Xavi Bou (previously) tracks and records the flight patterns of birds, combining their repetitive movements into elongated shapes that twist through the sky for his series Ornitographies. The images are inspired by chronophotography, a Victorian era photography method that combined multiple images to create movement, and edited digitally in Photoshop. The layered images appear like floating double helixes or fringed ribbon depending on the size and wingspan of each bird, and create elegant gestures as they criss-cross against the blue sky.

Recently Bou traveled to Iceland where he captured new species of birds set against a dramatically different landscape than his previous images. “Iceland was especially interesting because I was looking for the contrast between the size and heaviness of the volcanic rocks, in contrast between the tiny patterns that marine birds create in the sky,” he tells Colossal. Bou has also recently visited Barcelona to watch pigeons race across the city, and Tarifa, Spain to experience thousands of birds from all over Europe cross the sea towards Africa. You can see more of his multi-shot avian images on his website and Instagram.

A Nearly Perfect Rectangular Iceberg Spotted in the Antarctic

Earlier this month NASA’s cryosphere research division, NASA ICE, posted an image of a peculiar iceberg floating near the Larsen C Ice Shelf. Its perfectly rectangular shape and flat surface sparked the interest of many online, but its form is one that is more common than one might expect. Unlike the recognizable pyramid-shaped icebergs, tabular icebergs split from the edges of ice shelves when they become too brittle. In 2017 an iceberg the size of Delaware broke off of the same arctic ice shelf. The iceberg weighed over a trillion tons, and was one of the largest ever recorded.

The recent image of the tabular iceberg was taken as a part of Operation IceBridge, NASA’s extensive survey of Earth’s Arctic and Antarctic ice sheets, ice shelves, and sea ice. You can see the edge of the perfectly formed tabular iceberg in addition to a slightly less rectangular example in the image taken by IceBridge senior support scientist Jeremy Harbeck below. A GIF of a plane from NASA’s Armstrong Flight Research Center approaching the iceberg can be viewed their Twitter. (via NASA ICE)

Spooky X-Rays Reveal the Bone Structures of Oregon Zoo Residents

October 18, 2018

Kate Sierzputowski

As a seasonally appropriate topic for Halloween, the Oregon Zoo is posting a few of their favorite animal X-rays taken during routine health exams. Included in the mix is a branch-dwelling chameleon, open-beaked toucan, and a bat that appears to be caught mid-flight. The scans are a normal part of the check-ups at the zoo, and are used by animal experts as a helpful diagnostic tool to minimize anesthesia and provide faster results. You can follow more of the zoo’s spooky posts on Twitter.

A Million Dazzling Stars Are Revealed in a New Infrared Photograph of the Carina Nebula

September 17, 2018

Laura Staugaitis

A new photograph of the Carina Nebula, a complex group of bright and dark nebulae in the constellation Carina, has just been released by the European Southern Observatory. The original image is 140 megapixels, which clocks in as a 344MB download (don’t try this at home, kids) and contains about one million stars.

As explained by astronomer and science communicator Phil Plait, “The colors you see here are not what you’d see with your eye, since it’s all infrared. What’s shown as blue is actually 0.88 microns, or a wavelength just outside what your eye can see. Green is really 1.25 microns and red is 2.15, so both are well into the near-infrared. Even in the infrared, a lot of gas and dust still are visible. That’s because there’s a whole bunch of it here. And it’s not just randomly strewn around; patterns are there when you look for them.”

Plait continues on to clarify that the purpose of such an impressive photo isn’t just for eye candy: astronomers use such images to conduct star censuses. Below are two details of the photo, where you can get a better sense of the extreme density of stars captured in the massive image. (via Kottke)

The Museum of the Moon: An Illuminated 23-Foot Lunar Replica Currently Touring the World

September 13, 2018

Multidisciplinary artist Luke Jerram has created several exacting 23-foot replicas of the moon, which are currently touring the world as Museum of the Moon. The lunar project has been installed in public spaces ranging from China and Finland to the United Arab Emirates and Australia, and is accompanied by music from composer Dan Jones. Locations vary and include indoor and outdoor spaces as well as festivals, to intentionally alter the interpretation and experience of the project for viewers around the world.

To create the large illuminated sculptures, the British artist used a massive image (nearly 70 feet wide) of the moon created by NASA’s Astrogeology Science Center. The image itself was taken by a NASA satellite carrying the Lunar Reconnaissance Orbiter Camera, which was launched in 2010. Each centimeter of Jerram’s replicas represent 5 kilometers of the moon’s surface.

Jerram also shares in a statement, “As it travels from place to place, it will gather new musical compositions and an ongoing collection of personal responses, stories and mythologies, as well as highlighting the latest moon science.” This information is compiled on Museum of the Moon online research page. You can find out where the moons will be next on the museum’s website and see photos with the #museumofthemoon hashtag. (via designboom)

The Milky Way’s Glimmering Core Captured in a Timelapse Video by Adrien Mauduit

September 7, 2018

Laura Staugaitis

When not working for a NASA-funded citizen-science project, Adrien Mauduit travels the world seeking out remote places to create photographs and films of the night sky. To the naked eye, the galaxies around us appear as single points of light; Mauduit’s “astro-lapse” visuals showcase the dimensionality of the universe through specialized photo and video equipment. His most recent video, Galaxies Volume III, is the third in the astro-lapse series and focuses on the core of the Milky Way.

Mauduit explains in a statement about the project that from a young age he has been interested in  the natural wonders of the environment, and by “showing the true beauty of the universe I could contribute in my own limited way to bringing the real dark skies to the hectic and light polluted urban jungle.” The resulting film includes dramatic shots of shooting stars, silhouetted mountains, and rushing clouds foregrounding the shimmering night sky. You can see more of Mauduit’s work on Vimeo and Instagram. (via Vimeo Staff Picks)

These Sneaky Sea Slugs Paralyze Their Predators With Stolen “Weapons”

August 30, 2018

Kate Sierzputowski

Nudibranchs, or sea slugs, and are group of wildly colored animals that use their striking forms to warn predators against attack. Although the sea slugs move slow, they are protected by a brilliant defense mechanism. Some species create an alarming defense by stealing “weapons” from another creature called a hydroid. These plant-like animals may appear like seaweed, but they are actually a jellyfish relative covered in stingers packed with a paralyzing venom.

Instead of being repelled by the dangerous tentacles covering the hydroids’ bodies, nudibranchs devour them. Once swallowed, some of the immature stingers are passed directly into their digestion system and are stored in their spikes. If a sea slug feels threatened, these stingers are deployed for an overwhelming punch of stolen venom. For more information on nudibranchs and their sneaky defense system, view this article from KQED Deep Look. (via The Kid Should See This)
