Walkabout the Galaxy
Cassini, Saturn's rings, exoplanets, negative mass
Astrophysics and Astronomy | Physics
No, that ain't no negative mass, but yes, for Cassini the end is nigh. The series of 22 Grand Finale orbits has begun, providing unique views of Saturn and its rings and a way to probe the planet's interior and magnetic field. The astroquarks also check out yet another exoplanet in the habitable zone of a nearby star and discuss the headline about a discovery of "negative mass".
While you walk about the galaxy, I journey through time. I have the ability to go anywhere in the history of the universe, fighting evil in all its forms, usually in late 20th century and early 21st century United Kingdom, Earth, Solar System, Milky Way Galaxy, local group, etc., etc. But I could truly go anywhere, that's why I'm called Dr. When. My powers over time are so great that you could call me a lord of time. So in your walk about the galaxy, if you ever run into trouble, make your way to late 20th century, actually, let's just make it 2017, in the United Kingdom, I'll be then.
