Walkabout the Galaxy
New Horizons; Kuiper belt; Lucy mission
Astrophysics and Astronomy | Physics
The intrepid New Horizons spacecraft has discovered close binary comets in the Kuiper belt, and the Lucy mission is getting ready to explore binary trojan asteroids sharing Jupiter's orbit. It's all about small bodies, including just how late we can nuke an inbound asteroid and live to tell the tale.
When you're measuring the time it takes for light to cross an atom, put your stopwatch away and get your supply of attoseconds ready. At one quintillionth, or one billion of a billionth, of a second, the attosecond is to that everyday tick of the clock what a half second is to the age of the Universe, and then some. Impress your friends by telling them how long you worked out in attoseconds. Attoseconds are available now for the low, low price of 300 million billion for the blink of an eye. If you want to tap your feet to the beat of a different, and extremely active drummer, get attoseconds. Attoseconds, bet you can't eat just one (Lays).
