Walkabout the Galaxy
gamma rays, dark matter, high energy sources of light, Perseverance, Ingenuity, Mars Insight
Astrophysics and Astronomy | Physics
The center of our galaxy is producing more gamma rays than we can account for. Some say dark matter is the explanation, and others say no way. We explore the different scenarios for the high energy source of this extra light, and closer to home check in on Mars with updates from Perseverance, the Ingenuity drone, and Mars Insight quakes.
Tired of waking up on a winter morning and having to scrape the ice off your car's windows and windshield? Has the condensation on your soda glass once again soaked and ruined the homework you were slaving over for hours? Then it's time to say goodbye to H2O condensate and hello to Bose-Einstein condensate. This quantum mechanical peculiarity won't be troubling you until the temperature drops down to a few hundred billionths of a Kelvin. And if it's that cold, believe us, condensation will be the least of your worries. So bye-bye windshield scrapers and icicles, hello macroscopic quantum mechanical properties of a dilute, ultra-cold gas. Bose-Einstein condensates, why there is no tomorrow (FedEx).
