How can we know the size, composition, and atmospheric makeup of distant exoplanets? NASA explains the details in this Alien Atmospheres video. 

By observing periodic variations in the parent star’s brightness and color, astronomers can indirectly determine an exoplanet’s distance from its star, its size, and its mass. But to truly understand an exoplanet astronomers must study its atmosphere, and they do so by splitting apart the parent star’s light during a planetary transit.

Artist Soo Sunny Park's Unwoven Light, filmed by Walley Films.

Seeing a Styrofoam cup stuck on a fence one day got Park thinking about the chain link’s properties of being both rigid and porous, of acting as a boundary while retaining an appearance of openness… 

Explains Park, “Like a net, the sculpture is a filter that is meant to capture the light that is already there and force it to reveal itself. Now we can see it, the light, in purple shadows and yellow-green reflections that both mirror the shape of the fence and restructure the space they inhabit.”

Science experiments + a cute and furry blue monster that we know and love = YES. Hosts Annie Colbert and Matt Silverman have clearly helped discover the formula for making an instant video favorite. From 5facts and Sesame Street:

GROVER DOES SCIENCE.

Seriously: It’s seven minutes of pure joy. 

We’ve featured a few similar experiments on the site before, but it goes without saying that everything is better with Grover. For more info on the experiments above, Mashable has step-by-step instructions, and for more Sesame Street-hosted science, technology, engineering, and math that you can do at home, visit SesameStreet.org/STEM.
