A virtual reality experience of being inside an exploded star

Cassiopeia A, the youngest known supernova remnant in the Milky Way, is the remains of a star that exploded almost 400 years ago. The star was approximately 15 to 20 times the mass of our sun and sat in the Cassiopeia constellation, ...

Hybrid qubits solve key hurdle to quantum computing

Spin-based quantum computers have the potential to tackle difficult mathematical problems that cannot be solved using ordinary computers, but many problems remain in making these machines scalable. Now, an international group ...

Reactive optical matter: Light-induced motion

Newton's third law dictates that forces between interacting particles are equal and opposite for closed systems. In a non-equilibrium environment, the third law can be defied, giving rise to "nonreciprocal" forces. Theoretically, ...

Laser diode detects counterfeit olive oil

Researchers at the Complutense University of Madrid (UCM) and the Scintillon Institute in the U.S. have designed a sensor that can detect counterfeit olive oil labeled as extra virgin or protected designation of origin.

ESA sets clock by distant spinning stars

ESA's technical centre in the Netherlands has begun running a pulsar-based clock. The "PulChron' system measures the passing of time using millisecond-frequency radio pulses from multiple fast-spinning neutron stars.

Mission accomplished for ESA's butane-propelled CubeSat

The cereal-box sized GomX-4B – ESA's biggest small CubeSat yet flown – has completed its mission for the Agency, testing out new miniaturised technologies including: intersatellite link communication with its GomX-4A ...
