Parsecs are actually astronomical units—not just in the Star Wars universe—used to measure distance, not time. (Sorry, Han.)

As the Museum prepares for its upcoming transformation, the Smithsonian is eyeing a remake of its iconic film Scott Hamilton Skates the Universe.

Tomorrow's supermoon is actually being called a “super blue blood moon,” and it’s really rare. Here's what to look for.

If you looked up at the sky on January 1, you might have witnessed something spectacular--the Moon kicked off the year with the biggest full moon of 2018, a supermoon. But what about the Sun; did you know that it can be super, too?

Using satellites and robotic rovers, we’ve learned quite a few details about the various planets orbiting our Sun. But what about other stars? What are their planets like? How weird do they get? It turns out, pretty weird.

Hoping to catch a view of the Orionid meteor shower tonight? Here are the five things you need to know from the astronomy team at the Phoebe Waterman Haas Public Observatory.

For the first time ever, on August 17, 2017, astronomers detected the collision of two neutron stars. Not satisfied with that, they caught the cosmic smashup using both gravitational waves and light – another breakthrough.

Here we are, less than one week until a total solar eclipse crosses the United States. For the past three years, my excitement has been building, and all of my eclipse-chaser friends have been saying, “You HAVE to go see totality!” The path of totality (the narrow region where the Sun will appear totally blocked) is relatively convenient for North Americans, but many people won’t be able to travel and witness the total phase of the eclipse.

On Monday, August 21, a total solar eclipse is sweeping the nation. All of North America will be able to see at least a partial eclipse, but 14 states across the U.S. will have the unique opportunity to see a total solar eclipse, called the path of totality. There are approximately 12.5 million people living in the path of totality—an occurrence that happens only once where you live every 375 years! On the day of the eclipse, STEM in 30, a TV show we produce at the National Air and Space Museum for middle school students, will be broadcasting live from the path of totality in Liberty, Missouri, starting at 1:30 pm EST.
