MicroObservatory observes Solar Eclipse 2017!

On August 21, 2017, observers all over the United States will be witnessing this amazing celestial line-up. Anyone within the path of totality — a 70 mile-wide strip of land that stretches from Salem, Oregon to Charleston, South Carolina — will be able to see the moon completely covering the disk of the Sun (weather permitting!). Observers outside this path will still see a partial solar eclipse where the moon covers part of the sun's disk. Those of you outside the path of totality, don’t be discouraged, partial phases of the total solar eclipse are still an incredible viewing opportunity (Make sure to view safely)!

View With Us!

Our MicroObservatory telescopes will be joining the fun of observing the partial phases of this solar eclipse by taking images every 3 minutes throughout the entire event! MicroObservatory telescopes stationed in Amado, AZ and Cambridge, MA will observe from the Northeast and the Southwest — giving you an opportunity to view this amazing event from both sides of the path of totality. Follow along with us as we track the progression of the moon crossing in front of the Sun by viewing our eclipse images in the recent image directory. Then compare them to what you see at home, using one of these safe-viewing methods.

Don’t forget to take your OWN MicroObservatory image of the Solar Eclipse by requesting an image of the Sun on Monday!

WISE Eyes the Skies

WISE satellite

NASA's Wide-field Infrared Survey Explorer observes the "nearby" Pleiades cluster and Andromeda Galaxy. Infrared light is the part of the electromagnetic spectrum just below the low-energy red light our eyes can observe, so the WISE images that we see are "representational color." Can you use the color tables in the image-processing software to make your OWN false color images?

First Light for SDO

Sun Flare

NASA's Solar Dynamics Observatory is helping astronomers understand the Sun's influence on Earth and Near-Earth space by studying the solar atmosphere across many wavelengths, or energies, of the electromagnetic spectrum. SDO is part of NASA's Living with a Star program.

During April 2010, MicroObservatory joined Astronomers Without Borders in celebrating Global Astronomy Month, the biggest effort ever to spread remote astronomy around the world. The goal of GAM2010 has been to help people to connect across borders and to feel—even if they are on opposite sides of the world—that they are all sharing the same sky.

LCROSS Impact on Moon


NASA's Lunar Crater Observation and Sensing Satellite, or LCROSS, created twin impacts on the moon's surface on October 9, 2009 in a search for water ice. Scientists are now analyzing the data from the spacecraft's instruments to assess whether water ice is present. Read more about LCROSS at the following websites:

International Year of Astronomy 2009

IYA logo

This year, the entire world is celebrating the International Year of Astronomy as it commemorates the 400th anniversary of Galileo's use of a telescope to study the skies, and Kepler's publication of Astronomia Nova. 2009 is also the anniversary of many other historic events in science, including Huygen's 1659 publication of Systema Saturnium. This is modern astronomy's quadricentennial, and the 2009 Year of Astronomy celebrates numerous astronomical and scientific milestones. Events are happening every month. To find out more, visit any of these IYA 2009 websites:

Spread the word: the Universe is yours to discover. Come celebrate in 2009.

During May and June, the Smithsonian Photography Initiative offers three ways to celebrate both the International Year of Astronomy and the 400th anniversary of the first recorded astronomical observation with a telescope by Galileo Galilei.

Call for Entries

The Smithsonian Photography Initiative invites the public to contribute images and stories to "click! photography changes everything" (, an online exhibit that explores how photography influences every aspect of people's lives. This month's focus is "Seeing Other Worlds":

  • Entries selected for the "click!" Web site will be eligible to receive a copy of the book "At First Sight: Photography and the Smithsonian," an intriguing glimpse into the Smithsonian's more than 700 photographic collections.

Congratulations to 100 Hours of Astronomy!

100 Hours of Astronomy

Between April 2 and April 4 nearly 1,000,000 people participated in 1500 events in 130 different nations around the globe. These individuals participated in science, making 2.6 million classifications of galaxies at Galaxy Zoo, they followed webcasts through Around the World in 80 Telescopes, and they got involved in remote observing and face to face observing at star parties, real and virtual. Over 1000 guest observers used the MicroObservatory telescopes during 100 Hours of Astronomy!

To all of you who participated: Thanks for joining us in a truly historical event.
