Walkabout the Galaxy
quantum-fuzzy nuclei; nucleosynthesis; Juno spacecraft; Jovian cloud tops; exoplanet geological activity
Astrophysics and Astronomy | Physics
Scientists are creating large, quantum-fuzzy atomic nuclei with large numbers of neutrons to get clues about nucleosynthesis in the very early universe. Closer to home, the Juno spacecraft has peered hundreds of km below the Jovian cloud tops to better understand its colorful stripy system of bands and zones. And we get to say "fugacity" a lot in understanding exoplanet geological activity. Join us for all this, space news, and top quark trivia.
If you're tired of the languid pace of circling the galactic center every quarter billion years or so or would just like a taste of that high energy night life that you can only find in the close vicinity of a supermassive black hole, then come on down to galactic central park at Sagittarius A*. Located at the heart of your very own Milky Way Galaxy, that asterisk in our name is no footnote. Sagittarius A* is the beating heart of the Milky Way with 4 million solar masses inside the event horizon and just outside you’ll find a potent source of X-rays, radio waves, and every wavelength of light in between. So if you'd like to see those bright city lights, come downtown to Sagittarius A* and whirl around the heart of your galaxy at relativistic speeds. Sagittarius A* may be hazardous to all life forms due to intense radiation. Sagittarius A* assumes no liability for radiation burns, spaghettification, or irretrievable loss inside the event horizon. Sagittarius A*: "It’s a dictatorship at the door and a democracy on the dance floor" (Andy Warhol re Studio 54).
