Slicing Silhouettes of Jupiter: Processing JunoCam Images

With the images from the Juno mission being made available to the public, I thought it might be fun to try my hand at some image processing with them. Though my background is not in image processing, the Wolfram Language has some really nice tools that lessen the learning curve, so you can focus on what you want to do vs. how to do it.

Get Ready for the Total Solar Eclipse of 2017

On August 21, 2017, an event will happen across parts of the Western Hemisphere that has not been seen by most people in their lifetimes. A total eclipse of the Sun will sweep across the face of the United States and nearby oceans. Although eclipses of this type are not uncommon across the world, the chance of one happening near you is quite small and is often a once-in-a-lifetime event unless you happen to travel the world regularly. This year, the total eclipse will be within driving distance of most people in the lower 48 states.

New Books on Applications of the Wolfram Language

We're always excited to see new books that illustrate applications of Wolfram technology in a wide range of fields. Below is another set of recently published books using the Wolfram Language to explore computational thinking. From André Dauphiné's outstanding geographical studies of our planet to Romano and Caveliere's work on the geometric optics that help us study the stars, we find a variety of fields served by Wolfram technology.

Exploring Exoplanet Systems with the Wolfram Language

Exoplanets are currently an active area of research in astronomy. In the past few years, the number of exoplanet discoveries has exploded, mainly as the result of the Kepler mission to survey eclipsing exoplanet systems. But Kepler isn't the only exoplanet study mission going on. For example, the TRAnsiting Planets and PlanetesImals Small Telescope (TRAPPIST) studies its own set of targets. In fact, the media recently focused on an exoplanet system orbiting an obscure star known as TRAPPIST-1. As an introduction to exoplanet systems, we'll explore TRAPPIST-1 and its system of exoplanets using the Wolfram Language.

Academy Award-Winning Interstellar Visuals Prototyped with the Wolfram Language

Kip Thorne, physicist, New York Times bestselling author, and professor emeritus at Caltech, ignited fans' passion for science through his work on the movie Interstellar. The sci-fi adventure won the 2015 Academy Award for Best Visual Effects, and the first cuts of some of those stunning visuals were created with Mathematica and the Wolfram Language. "Mathematica was my way of testing whether or not I had the equations right," says Thorne, whose computational approach to producing images led to publication in the American Journal of Physics and Classical and Quantum Gravity.

On the Detection of Gravitational Waves by LIGO

Earlier today at a press conference held at the National Science Foundation headquarters in Washington, DC, it was announced that the Laser Interferometer Gravitational-Wave Observatory (LIGO) confirmed the first detection of a gravitational wave. The image reproduced below shows the signal read off from the Hanford, Washington, LIGO installation. The same signal could be seen in the data from the Livingston, Louisiana, site as well. While this signal may not seem like much, it is one of the most important scientific discoveries of our lifetime.

Solar Eclipses from Past to Future, Earth to Jupiter

You may have heard that on March 20 there was a solar eclipse. Depending on where you are geographically, a solar eclipse may or may not be visible. If it is visible, local media make a small hype of the event, telling people how and when to observe the event, what the weather conditions will be, and other relevant details. If the eclipse is not visible in your area, there is a high chance it will draw very little attention. But people on Wolfram Community come from all around the world, and all---novices and experienced users and developers---take part in these conversations. And it is a pleasure to witness how knowledge of the subject and of Wolfram technologies and data from different parts of the world are shared.
