You can use your own telescope or telescopes you control over the internet to help the James Webb Space Telescope (JWST) study exoplanets. Through NASA's Exoplanet Watch program, your observations can help determine the exact times that an exoplanet will be crossing in front of its star giving the right window of time for JWST to observe it. Join astronomer Dr. Rob Zellem as he describes how helping study planets around other stars is at your fingertips!
What happened to make the star Eta Carinae become the second brightest star in the sky in 1843? Why did it then dim over the next century and once again brighten? How can YOU take images of this star and its surrounding clouds using NASA’s robotic telescopes or create your own images using NASA data? Join us to hear the fascinating story of Eta Carina and how NASA’s Astrophoto Challenges gives you the opportunity to make a picture of this star and its surroundings.
Thirty years ago we knew of no planets orbiting other stars. In the rest of the 90s with discoveries of the first exoplanets (planets orbiting around OTHER stars) the numbers began to grow slowly. Finally in the past 10 years the numbers of exoplanets have increased rapidly and we have just passed the 5000th confirmed known exoplanet! Join us for a chat with exoplanet scientist Dr. Jessie Christiansen about how we have managed to discover so many planets around other stars and what the future holds for this exciting area of astrophysics.
Are we helpless against the kind of asteroid impacts that wiped out the dinosaurs? Not if we DO look up! For several decades there have been multiple surveys to chart and track potentially hazardous Near-Earth Objects (NEO) which can cause significant disasters if they hit the Earth. Join our conversation with two astronomers who have already tracked many NEOs and are working on NASA's next NEO-seeking space telescope called the NEO Surveyor.
The James Webb Space Telescope is NASA's next major space observatory, which will study everything from the earliest stars in the Universe, to planets orbiting other stars, to nearby asteroids. Learn all about it from our guests who are involved in both building and using the telescope.
A planet may have been detected in a galaxy outside of our own. There are thousands of planets detected around stars in our own Milky Way galaxy, but for the first time we may have detected a planet in another galaxy, called the Whirlpool Galaxy, which is more than 23 MILLION lightyears away.
In 2017 astronomers remarkably detected the first known example of an object originating from OUTSIDE of our solar system as it was briefly passing THROUGH our solar system. But was it just a rock, or something more?
Make your own images of the amazing galaxy M87— host to a supermassive black hole — using data from NASA’s space telescopes or ground based telescopes. Try these challenges and your entry could be selected as a standout for recognition from NASA scientists!
What happens when the largest stars in the universe go boom? Astronomers Schuyler van Dyk (Caltech-IPAC) and Bill Blair (Johns Hopkins University) talk all about some of the biggest explosions around and how a lot of stuff in you and the world around you came from them billions of years ago.
When we look for exoplanets, planets beyond our own solar system, we focus on the habitable zone… But … what’s that mean?! Tune into our live video chat with NASA scientists.
NASA’s Universe of Learning materials are based upon work supported by NASA under cooperative agreement award number NNX16AC65A to the Space Telescope Science Institute, working in partnership with Caltech/IPAC, Center for Astrophysics | Harvard & Smithsonian, and NASA Jet Propulsion Laboratory. The award is part of NASA’s Science Activation program, which strives to further enable NASA science experts and content into the learning environment more effectively and efficiently with learners of all ages.
