Tonight, Saturn is at opposition. What does this mean? The ringed planet, Saturn, lies on the opposite side of Earth from the Sun, which means it is visible from sunset to sunrise! #wherethestarshangout

Hooray, it's Apple Harvest Festival today!

We are so thrilled to premiere the brand new planetarium show ""Beyond Our Senses: Bank Swallows."" The creator, David Andrew Busse will be here all day, to hear your feedback on this show as it continues to gain exposure and viewers.

Look to the east just before sunrise today, you'll see a trio of celestial objects in a magnificent conjunction. Look east toward the waning, crescent Moon setting in the sky and you'll notice that the Moon will be nestled up right next to both Venus and Regulus, one of the brightest stars in the night sky. The three are part of a conjunction, which simply means that they look close together in the sky (even if they’re actually far apart in space).

On this day in 1992, Dr. Mae Jemison made history as the first African American female to venture into space. Selected for the astronaut program in June 1987, Jemison served as the science mission specialist on STS-47 Spacelab-J, a collaborative mission between the U.S. and Japan. The mission comprised 44 life science and materials processing experiments, including a bone cell research experiment in which Jemison was a co-investigator. During her inaugural space flight, Jemison accumulated 190 hours, 30 minutes, and 23 seconds in space. Photo & Content Credit: NASA
