These videos inspire and engage students, helping them see real world connections. The maps are presented as a video, which provides a dynamic three-dimensional representation of the universe through the use of rotation, panning, and zooming.
The video was announced last week at the conference "Cosmic Flows: Observations and Simulations" in Marseille, France, that honored the career and 70th birthday of Tully. The Cosmic Flows project has mapped visible and dark matter densities around our Milky Way galaxy up to a distance of million light-years.
The large-scale structure of the universe is a complex web of clusters, filaments, and voids. Large voids—relatively empty spaces—are bounded by filaments that form superclusters of galaxies, the largest structures in the universe.
Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. The technique, known as freelensing, allows you to twist and alter the angle of the lens, which shifts and skews the plane of focus. This can create wonderful painterly effects. While the process itself is relatively straightforward, it also involves a lot of trial and error.

Hubble Telescope Reveals Deepest View of Universe Ever The Hubble Space Telescope has captured the farthest-ever view into the universe, a photo that reveals thousands of galaxies billions of light-years away. Only the accumulated light gathered over so many observation sessions can reveal such distant objects, some of which are one ten-billionth the brightness that the human eye can see.
The photo is a sequel to the original "Hubble Ultra Deep Field," a picture the Hubble Space Telescope took in and that collected light over many hours to reveal thousands of distant galaxies in what was the deepest view of the universe so far.
The XDF goes even farther, peering back From cutting-edge cryogenic tissue storage to decades-old, handmade, fossil-preparation equipment to the Big Bone Room, we learned how the museum helps discover, advance and preserve the knowledge it is best known for putting on display.
Getting to the various labs and back rooms of the museum involves navigating a confusing agglomeration of large spaces lined with tall cabinets containing all manner of beetle, bird and badger specimens; riding in oversized elevators; and walking down long, cluttered hallways with exposed pipes and a strange mix of outdated, faded science and safety posters on the walls. So entering the sterile, spare, high-tech frozen-tissue laboratory is like stepping into another world.
The Ambrose Monell Cryo Collection consists of eight nearly indestructible liquid-nitrogen—fueled cryogenic tanks. Three are already online, preserving 70, tissue samples from reptiles, amphibians, mammals, insects, fish and birds.
The space can fit four more vats, and at full capacity could store and catalog a million samples. It's one of the things that makes this collection unique," said Julie Feinstein, collections manager for the tissue lab.
The cryovats take the place of the many individual collections that used to be kept in freezers in labs all over the museum.
Those samples were vulnerable to power outages and even when they managed to stay frozen, they were kept between minus 4 and minus Fahrenheit, which is not cold enough to prevent all damage and degradation over time. The bottom of the vats are filled with liquid nitrogen that is below minus , always keeping the tissue colder than minus Even in the event of a catastrophic power failure, the vats will stay cold for five weeks on their own.
And they are on wheels, so the samples can be moved without taking them out of the freezers. There's also a dedicated staff just for the frozen collection. The tissue library is also protected against loss and misplacement by a meticulous computer tracking system that involves bar codes and human-readable numbers.
The cryostorage supports the museum's genetic-analysis and conservation studies, but the lab will store samples for any scientist with a need who is willing to relinquish ownership and share. The types of samples range from mammal blood to bird liver to whale skin.
The lab recently received some samples of bats with White Nose syndrome, which threatens bat populations in the eastern United States, and is already receiving requests from other researchers to study them. It is the premier tissue storage facility in the world, and the Smithsonian, Harvard and Yale natural history museums are hoping to model their own collections after it, Feinstein said.
The American Museum of Natural History is known for the biggest chunk of meteorite on display in any museum: The Ahnighito meteorite weighs 34 tons and requires extra reinforcements in the basement to hold it up. But the museum's geologists are busy studying bits of meteorites that are even more interesting, at least scientifically. Though Ebel claimed to have just five minutes to spare because he needed to work on an abstract for submission to the upcoming Meeting of the Meteoritical Society in New York, once he got started talking about meteorites, he forgot all about the deadline.
Ebel's team is working on 3-D imaging of meteorites, which will soon get a boost from a new CAT scan that will soon be arriving at the museum. He's also building a library of the infrared spectra.
This will help astronomers interpret data from the Herschel Space Observatory by comparing the infrared wavelengths emitted by planetary nebulae, supernova remnants, interplanetary dust and circumstellar disks to the spectra recorded in the lab and cataloged in the library.
When a technician at the lab casually mentioned a place called the Big Bone Room, we knew we had to go there. And we were right. This room lives up to its name. Despite the many, many bones visitors can see at the museum, only 0.
The rest are scattered throughout the back rooms and labs of the museum, but all the really big ones are in the Big Bone Room. The room is like a library of huge fossils, complete with rolling stacks full of shelves of dinosaur bones. And though most of these fossils will never be seen by the public, many of them will be seen by scientists, both from the museum and from other institutions. Many of them were collected in the late 19th century.
Mehling clearly loves the fossils and is very happy to show them off, but he's also very protective of the fragile specimens. Below: 1 The biggest bone in the Big Bone room is the femur of a camarasaurus, and looks to be close to 5 feet long. Some of the prize fossils in the collection are type specimens, the very first of their kind to be described in the scientific literature, such as this Anchiceratops, which was on display in the museum at one time.
At the top of the museum a team of artists and other creative types build the exhibits in a big room filled with tools, paint and the remnants of previous projects. The museum employs 12 permanent artists.
