Hypnotic Photographs of the Milky Way Over Yellowstone National Park

After a storm passed through Yellowstone National Park, astrophotographer David Lane captured the stunning beauty of the Milky Way covered sky above the Abyss Pool region. Although the photographs were taken at night, the illuminating beauty from the Milky Way gave the landscape sufficient light and a magical element to deliver this stunning sight. This natural phenomenon is defined as an airglow impedes the sky from becoming completely dark. To assure that the images match the park’s vision during the day time, Lane spent four extra months on color correcting his collection.

Astrophotography Basics - The Blue Moon

Astrophotography is one of those things that sounds challenging but is really easy to jump into. All you need is a basic telescope and a smart phone, a DSLR camera, or a smart telescope like neogalactics.com.

The first 2 images of the moon were taken with a smart phone and a basic telescope - the non-remote version of the elon1 with the same specs as a celestron 1st scope. Simply holding a camera up to the eye piece is enough for quality images of the Moon or planets.

The photos of the stars and the last photo of the moon were taken with an Olympus OM-D E-M10 with a 14-42mm, F3.5-F22. The settings used to take these pictures were ISO 200, F3.5, and a shutter speed of 15 seconds. Shout out to leenabee for helping with the photography - she has a new photography blog at leenabee.tumblr.com. More astrophotography basics coming soon!

😎: Yeah, really.

Bonus: Will the planets ever be aligned? The closest that the eight planets will come to alignment will be on May 6, 2492… and even then they won’t be *totally* lined up one after another. Here’s what that will look like:

There’s just too many ways to arrange the eight planets. But our future selves are gonna have one cool evening sky in 2492, eh?

This gif is an awesome illustration of how astronomy has advanced over the last 85 years. NASA assembled a 17-frame chronological sequence of observations of Pluto, starting with its discovery by American astronomer Clyde Tombaugh in 1930 while working at the Lowell Observatory in Flagstaff, AZ and ending with the zoomed-in, close-up view courtesy of the New Horizons probe received on July 15, 2015.

Stellar Sparklers That Last

While fireworks only last a short time here on Earth, a bundle of cosmic sparklers in a nearby cluster of stars will be going off for a very long time. NGC 1333 is a star cluster populated with many young stars that are less than 2 million years old – a blink of an eye in astronomical terms for stars like these expected to burn for billions of years.

Parallel Worlds Could Explain Wacky Quantum Physics
A new theory that interactions between parallel universes could explain all quantum behavior is gaining traction among physicists.

The idea that an infinite number of parallel worlds could exist alongside our own is hard to wrap the mind around, but a version of this so-called Many Worlds theory could provide an answer to the controversial idea of quantum mechanics and its many different interpretations.

Bill Poirier, a professor of physics at Texas Tech University in Lubbock, proposed a theory that not only assumes parallel worlds exist, but also says their interaction can explain all the quantum mechanics “weirdness” in the observable universe.

Poirier first published the idea four years ago, but other physicists have recently started building on the idea and have demonstrated that it is mathematically possible. The latest research was published Oct. 23 in the journal Physical Review X.


Quantum mechanics is the branch of physics that describes the rules that govern the universe on the microscopic scale. It tries to explain how subatomic particles can behave as both particles and as waves. It also offers an explanation about why particles appear to exist in multiple positions at the same time.

Johann Gabriel Doppelmayer - Tabula Selenographica (The first comparative chart of the Moon from which the names of many Lunar features have been derived), 1707.

Essentially a comparative chart, Doppelmayer constructed this map to illustrate the Lunar mapping of Johannes Hevelius (left) and Giovanni Battista Riccioli (right). The left hand Lunar map, composed by Hevelius, is a considered a foundational map in the Science of Selenography – or Lunar cartography.

This map first appeared in Hevelius’ 1647 work Selenographia which laid the groundwork for most subsequent Lunar cartographic studies. Here the Moon is presented as it can never be seen from Earth, at a greater than 360 degrees and with all visible features given equal weight. In this map Hevelius also establishes the convention of mapping the Lunar surface as if illuminated from a single source – in this case morning light. The naming conventions he set forth, which associate Lunar features with terrestrial locations such as ‘Asia Minor,’ 'Persia,’ 'Sicilia’, etc, were popular until the middle of the 18th century when Riccioli’s nomenclature took precedence.

The Riccioli map, on the right, is more properly known as the Riccioli-Grimaldi map. This was a significant Lunar chart and offered an entirely new nomenclature which, for the most part, is still in use today. Curiously, though Riccioli, as a devout Jesuit, composed several treatises denouncing Copernican theory, he chose to name one of the Moon’s most notable features after the astronomer – perhaps suggesting that he was a secret Copernicus sympathizer? Other well-known Lunar features named by Riccioli include the Sea of Tranquility where Apollo 11 landed and where Neil Armstrong became the first human to set foot on the Moon’s surface. The upper left and right hand quadrants feature decorative allegorical cartouche work that include images of Angelic children looking through a telescope and a representation of the Ancient Greek Moon goddess Selene. Additional mini-maps show the Moon in various phases of its monthly cycle. Below the map proper extensive Latin text discusses Selenography.
