Last September, NASA’s Double Asteroid Redirection Test (DART) spacecraft smashed into an asteroid, deliberately altering the rock’s trajectory through space in a first test of planetary defence.

Now scientists have deconstructed the collision and its aftermath — and learnt just how successful humanity’s punch at the cosmos really was.DART, which was the size of a golf cart, collided with a Great Pyramid-sized asteroid called Dimorphos. The impact caused the asteroid’s orbit around another space rock to shrink — Dimorphos now completes an…

Ways to Weigh a Neutrino
Ways to weigh a neutrino (symmetry magazine)

For decades scientists have tried to find a way to measure the mass of the lightest matter particle known to exist. Three new approaches now have a chance to succeed.

If you were asked to weigh something—your dog for example—how would you do it? You could set the dog in your car, watch the compression, measure how many inches the car is displaced, then convert that into a measurement of the dog’s mass. You’d need to know the weight of the car, the technical specifications of…

The Inner Beauty of Basic Electronics

Open Circuits: The Inner Beauty of Electronics is a visual feast for those who love electronics.

Eric Schlaepfer was trying to fix a broken piece of test equipment when he came across the cause of the problem—a troubled tantalum capacitor. The component had somehow shorted out, and he wanted to know why. So he polished it down for a look inside. He never found the source of the short, but he…
