This week marks the 18th anniversary of Chandra’s “First Light,” when the first publicly available images from NASA’s flagship X-ray mission were released back in 1999 . Week after week, month after month, year after year, Chandra continues to deliver amazing results and make truly extraordinary discoveries across space. Scientists know so much more about the Universe now than we did before this amazing telescope began its work.
Scientific imagery, especially those from space, can be both powerful and beautiful. The images created by professional and amateur astronomers alike are often striking. This gives science communicators an opportunity to use such images as an access point for the related subject matter. In other words, scientific images are a door through which we can walk towards the discoveries and insight that science can achieve.
The Aesthetics & Astronomy project (A&A) is a unique research project that aims to study exactly how people from different backgrounds and educational experiences interpret and interact with scientific imagery. Started at the Chandra X-ray Center and combining the expertise of astrophysicists, psychologists, image producers, and educators specializing in research methodology, A&A delves into how these images can be used as a vehicle for scientific information.
One question that A&A recently asked is: how effective are metaphors in communicating scientific results? To explore this question, the A&A project solicited input from nearly 2,000 participants and asked a series of questions through an online study. After presenting participants with four astronomical images — Sagittarius A*, Our Sun (solar flare), Cassiopeia A, and the Pinwheel Galaxy — they were shown three separate labels for each.
It’s Carnival time, folks, so let’s get started! Here is a brief look at interesting space stories from the past week.
At Universe Today, their writers have got the Universe covered. In one post, they take a look at an intriguing new result that may help tie "Joshua's Eclipse" to the Battle of Gibeon, showing how astronomy can help make connections in other fields such as history. http://www.universetoday.com/133166/ancient-annular-dating-joshuas-eclipse/

In another post, they explain the most recent exciting pass of the Juno spacecraft over the cloud tops of Jupiter. NASA is also offering the public the chance to vote on what features Juno should image next. Take a look! http://www.universetoday.com/133215/juno-buzzes-jupiter-cloud-tops/
Many people associate the Smithsonian Institution with a handful of museums on the National Mall in Washington, D.C., when, in fact, the Smithsonian consists of 19 museums, 9 research centers, a zoo, and affiliates around the world.
One fact that may not be known to some is that NASA’s Chandra X-ray Observatory is inextricably linked with the Smithsonian. The Smithsonian Astrophysical Observatory (SAO) in Cambridge, Mass., was at the center of the conception and development of the telescope and today it controls Chandra’s science and flight operations. In other words, Chandra is both a NASA and a Smithsonian mission.
One of the core tenants of the Smithsonian’s mission is the “increase and diffusion of knowledge.” This means that education and outreach can often take center stage at the Smithsonian. To highlight the important role education plays, the Smithsonian gives out one award every year to an employee that recognizes “creativity, excellence, and commitment to serving the nation through educational programming, exhibits, publications, and digital media.”
We are thrilled to announce that this year’s winner for the 2016 Smithsonian Education Achievement Award is Chandra’s visualization lead, Kimberly Arcand. Arcand was presented with the award on December 8, 2016 at the Smithsonian Castle in Washington, D.C. Among the Chandra-led projects being recognized were the NASA-funded public science programs "From Earth to the Universe" "Here, There & Everywhere," and “Light: Beyond the Bulb,” as well as Chandra community programs for girls and boys to improve coding skills with NASA data, and cutting-edge Chandra data visualization projects such as data-based 3D printed supernova remnants.
We are very pleased to welcome two special guest contributors to the Chandra blog. Amy Nuccitelli and Jonathan Brande both spent the summer of 2016 working as interns with the Chandra X-ray Observatory team at its Operations Control Center. Amy Nuccitelli will enter her junior year as a mathematics major at James Madison University in Harrison, VA, while Jonathan is pursuing a major in astronomy and a minor in computer science at the University of Maryland, College Park. We thank Amy and Jonathan both for their hard work on the Chandra mission and also for taking the time to share their experiences with the Chandra bog.

On August 5th, the 2016 Olympic Summer Games will begin with the Opening Ceremonies in Rio de Janeiro, Brazil. A new project from NASA’s Chandra X-ray Observatory and its Communications group takes a look at the amazing feats performed by Olympic athletes and tries to provide context for them in an innovative way.

Objects in space are rather far away. The Moon is our closest celestial neighbor at nearly a quarter million miles from Earth, and the nearest star, our Sun, is 93 million miles away.
These extreme distances mean that it’s usually impossible to touch real objects in space (meteorites that fall to the ground not withstanding). Advances in both astronomy and technology, however, now allow you to do the next best thing: hold a 3-D model of one based on real data.
The story behind such a remarkable feat starts with how astronomers study space. Unlike previous generations of sky gazers, today’s astronomers look at the Universe in many kinds of light, across the full electromagnetic spectrum. Through advanced telescopes and detectors, scientists can “see” from radio waves to gamma rays. Why is this important? We need to look at the Universe in all the types of lights to even begin to understand it.
Take X-rays, for example. Back in 1999, NASA’s Chandra X-ray Observatory was launched in order to observe the high-energy Universe including such things as colliding galaxies, black holes, and supernova remnants.
One such supernova remnant that Chandra studies is Cassiopeia A. About 400 years ago, in our own Milky Way galaxy, a star that was about 15 to 20 times the mass of our Sun, detonated in a supernova explosion.
