Hubble’s bright shining lizard star

The bright object seen in this Hubble image is a single and little-studied star named TYC 3203-450-1, located in the constellation of Lacerta (The Lizard). The star is much closer than the much more distant galaxy. …

Solar system: New insights into ring system

Astronomers have modeled the two rings around Chariklo, the smallest body in the Solar System known to have rings. This is the first time an entire ring system has been simulated using realistic sizes for the ring particles. The simulation revealed that the ring particles are much smaller than predicted or that an undiscovered shepherd satellite around Chariklo is stabilizing the ring. …

The world’s fastest film camera: When light practically stands still

Forget high-speed cameras capturing 100,000 images per second. A research group has developed a camera that can film at a rate equivalent to five trillion images per second, or events as short as 0.2 trillionths of a second. This is faster than has previously been possible.

Looking for the quantum frontier

A new theoretical framework has been developed to identify computations that occupy the ‘quantum frontier’ – the boundary at which problems become impossible for today’s computers and can only be solved by a quantum computer. The team demonstrates that these computations can be performed with near-term, intermediate, quantum computers.

Engineers investigate a simple, no-bake recipe to make bricks from Martian soil

Explorers planning to settle on Mars might be able to turn the planet’s soil into bricks without needing to use an oven or additional ingredients. Instead, they would need to apply pressure to compact the soil–the equivalent of a blow from a hammer. …
