Asteroids Crash Into Earth Over Twice as Often as 290 Million Years Ago

Scientists find that a surge in Earth impacts began during the Permian period, possibly because of disruptions in the asteroid belt. Continue reading Asteroids Crash Into Earth Over Twice as Often as 290 Million Years Ago

Arcade Asteroids, Now In Colour

Asteroids is one of the classic games of the early arcade era. Launched in 1979 by Atari, it relied upon using an XY vector monitor to deliver crisp graphics for its space-based gameplay. One of the limitations of the original arcade games was that the game was only rendered in a single colour, white. Over 30 years later, [Arcade Jason] decided to see what it would take to build a color Asteroids machine.

The hack relies on the fact that the original game used a four-bit resistor ladder DAC to draw vectors in different intensity levels. Through some ingeniously simple …read more

Light Replaces Electrons for Giant Vector-Graphics Asteroids Game

For all its simplicity, the arcade classic Asteroids was engaging in the extreme, with the ping of the laser, the rumble of the rocket, the crash of crumbling space rocks, and that crazy warble when the damn flying saucers made an appearance. Atari estimates that the game has earned operators in excess of $500 million since it was released in 1979. That’s two billion quarters, and we’ll guess a fair percentage of those coins came from the pockets of Hackaday’s readers and staff alike.

One iconic part of Asteroids was the vector display. Each item on the field was drawn …read more
