Capturing planets

(Phys.org) -- The discovery of planets around other stars has led to the realization that alien solar systems often have bizarre features - at least they seem bizarre to us because they were so unexpected. For example, many systems have giant planets closer to their star than Mercury is to the Sun, while other have the opposite - giant planets more than ten times farther way from their star than Jupiter is from our Sun. Astronomers think they understand how planets could end up close to the star: they gradually drift in from more customary orbits. But how can planets end up so far away?

Dancing droplets reveal physics at work
by Science News 5 days 3 hours ago
An oxygen droplet floating on its vapor (approaching from left at 12 centimeters per second) can be deflected by a small magnet (moving from bottom center at 7 centimeters per second) held beneath a sheet of glass. Such movies reveal the elusive behavior of droplets subject to what’s known as the Leidenfrost effect.
