Walkabout the Galaxy
supermassive black holes; intergalactic gas; near-Earth asteroid
Astrophysics and Astronomy | Physics
Astronomers have sighted a supermassive black hole ejected from its host galaxy and creating a wake of stars from intergalactic gas. And if that wasn't enough to blow your mind, closer to home we've seen organic molecules in the material returned from the surface of a near Earth asteroid. Join us for all this, a weird exoplanet, Apollo program trivia, and some surprising tangents.
If the Roman goddess of love has you feeling hot and bothered, that's nothing compared to what her namesake planet has in store for you. With temperatures reliably in the upper-800s Fahrenheit, you can pack lightly for your trip to the second rock from the Sun. Enjoy ballooning in the thick CO2 atmosphere, where you can enjoy Earth-normal temperatures and pressures, and check out the clouds of sulfuric acid as you enjoy a leisurely drift over the volcanic plains. Keep your Venusian getaway romantic with a stop at Aphrodite Terra in the Southern Hemisphere, you can leave your winter clothes behind for your getaway to Venus. Venus, reveal the goddess in you (Gillette Venus).
