Wild art? No, it’s a radio image of the heart of our Milky Way
Eyelash-like radio filaments accent the brightest feature in this image — a supermassive black hole.
- Chemistry
No, organic molecules alone don’t point to life on Mars
These carbon-based molecules, found in a meteorite, may reflect merely a mixing of water and minerals on the Red Planet over billions of years.
