The search for life is a pillar of Mars exploration. But our search isn’t only confined to the planets of our solar system. Radio telescopes search for signals of intelligent life from far away planets, orbiting other stars. In his story, “The Great Silence,” science fiction author Ted Chiang features the Arecibo telescope as he considers the significance of the animal life that surrounds it.
For the month of June, 30 beautiful images of the solar system are on display on the terrace by the Independence Avenue entrance. They are part of the From Earth to the Solar System exhibition developed by the Smithsonian Astrophysical Observatory/Chandra with the NASA Astrobiology Institute.
Nearly 50 years ago, John Glenn purchased a camera at a drug store that served as the first astronomical experiment performed by a human in space. That three-orbit voyage for Glenn included two cameras, one the Ansco he purchased and the other a Leica supplied by NASA. The flight not only kicked off decades of orbital experiences for U.S. astronauts, but also science experiments, observations, and thousands of rolls of film and digital files created through hand-held photography. The results of those experiments and the photos taken are what people left on Earth use even today to understand human spaceflight.
On the morning of March 2, I got an excited text message from fellow astronomy educator Shelley Witte, telling me that the International Space Station (ISS) and Space Shuttle Discovery would be coming very close to transiting the Sun from our position at the National Air and Space Museum’s Public Observatory at exactly 3:08 pm.
On Saturday, March 19, I was thrilled to participate in the first ever Sun-Earth Day Tweetup organized by the NASA Goddard Spaceflight Center. It was also the first time the Smithsonian officially participated in a Tweetup. The event was a great opportunity to give twitter fans (aka “tweeps”) some face-to-face interaction with our research scientists, curators and educators, and provide some fun hands-on learning that illustrated the Sun-Earth connection.
The Moon is one of the most easily recognized celestial objects and arguably the easiest one to observe. It is simple to view the changing phases from day to day, with your naked eyes. Binoculars or a telescope will reveal countless craters, ancient lava flows, and other intriguing lunar features.
The Public Observatory Project is just over a year old now, and in that time we’ve been experimenting with the telescope to discover what is visible in the daytime sky and devise ways that our visitors can have the best experience possible. One of our goals is to use our equipment to take images of the Sun, so that we can share our star’s day-to-day activities with the visiting public as well as those who can’t make it to the Mall to look through our telescopes.
“Remote sensing” is a term used to describe many different types of observations carried out at a distance. Aerial photos, satellite images of the Earth and planets, and telescope views of our solar system are all forms of remote sensing used to understand geology, climate, hazards, and changes over time.
