Collision
-
The LIGO collaboration has announced the detection of gravitational waves from a pair of neutron stars colliding. This marks just the second time ever that this kind of event has been spotted, as the smash-up sent ripples through spacetime itself.

If other star systems are anything like our own, they’ve probably had turbulent histories of exoplanets smashing into each other. And now, astronomers have found evidence of just such a cataclysm happening in the relatively recent past.
-
Data from the Juno probe found that Jupiter's core is less dense and more spread out than expected. Now, astronomers believe they have an answer – a huge ancient planet, with 10 times the mass of Earth, crashed into the gas giant in the early days of the solar system.

Of all the things you don’t want to lose, an asteroid with a chance of striking Earth is pretty high up the list. A potentially dangerous space rock called 2006 QV89 has been missing in action for 13 years, but now astronomers have finally found it, and ruled out an impact within the next century.

A Canadian startup is trying to push some pretty out-there new technologies into the motorcycle world. Variable riding position geometry, for one, as well as a traffic-tracking collision warning system designed to give riders an extra margin of safety on the road.

Observations have shown that the “back” of the Moon has a thicker crust and an extra layer of material compared to the side that faces Earth. Now, simulations have revealed one possible, explosive explanation – an impact with a huge object early on in the Moon’s life.

A cataclysmic collision between a pair of dead stars may have seeded our solar system with precious heavy metals including gold and uranium, according to a newly published study. If such an event were to be observed in the present day, it would be the brightest point in the night sky.

While many kids do like pushing grocery carts, they can get kind of over-enthusiastic about it, and often run into things as a result. It was with this supermarket hazard in mind that Ford recently created the one-off Self-Braking Trolley.

Galaxies smash into each other on a pretty regular basis, usually merging together. Using data and observations from Hubble and the Keck Observatory, astronomers have now imaged the late stages of this incredibly slow process for the first time.
-
According to the results of a new study, Uranus may have survived a dramatic collision with a protoplanet twice, or even three times the size of Earth roughly four billion years ago, back when the solar system was young.
-
It's been suggested that asteroids delivered water to a bone-dry early Earth, but whether that would work in practice remained unanswered. Now scientists at Brown University have tested the theory using a high-powered cannon, and found that a surprising amount of water is transferred in the process.

Collision Avoidance System technology uses a forward-looking radar system to alert drivers when they're rapidly approaching other vehicles. If those other vehicles are bicycles, however, their rear profile can make them difficult for the radar to detect. That's where iLumaware's Shield TL comes in.
