Walkabout the Galaxy
Einstein, relativity, black hole, Milky Way, Hayabusa-2
Astrophysics and Astronomy | Physics
We never get tired of Einstein being right, and once again his general theory of relativity is up to the challenge. The astroquarks take you on a tour to the black hole at the center of the Milky Way for another test of Einstein's theory of gravity, while closer to home the Japanese Hayabusa-2 mission has successfully grabbed some more asteroid rubble. Dr. Zoe Landsman, aka Beauty Astroquark, joins Josh and Jim on this walkabout with spaceships being propelled by sunlight, nerd news, and Apollo trivia.
Sagittarius A*: For your next galactic getaway, take a trip to Sagittarius A*, or as we like to call it, The Biggest Apple. Nestled at the heart of the Milky Way, you'll never be at a loss for fun at Sagittarius A*. Start your day off with a breakfast basking in the intense X-ray emission from nearby giant molecular cloud Sagittarius B2. Then after a quiet lunch with room service in our luxury accommodations, take a guided tour to the G2 gas cloud as it breaks apart on its descent toward the singularity. Evening dining and entertainment are limited only by your imagination and by the deadly high intensity radiation emanating from your galaxy's very own supermassive black hole. Sagittarius A*: Once you pop, you can't stop!
