How are planets formed?

How did the Solar System's planets come to be? The leading theory is something known as the "protoplanet hypothesis", which essentially says that very small objects stuck to each other and grew bigger and bigger—big enough ...

'Cavity protection effect' helps to conserve quantum information

The electronics we use for our computers only knows two different states: zero or one. Quantum systems on the other hand can be in different states at once, they can store a superposition of "zero" and "one". This phenomenon ...

Diamonds are a quantum computer's best friend

A new kind of quantum computer is being proposed by scientists from the TU Wien (Vienna) and Japan (National Institute of Informatics and NTT Basic Research Labs).

Evidence of a local hot bubble carved by a supernova

I spent this past weekend backpacking in Rocky Mountain National Park, where although the snow-swept peaks and the dangerously close wildlife were staggering, the night sky stood in triumph. Without a fire, the stars, a few ...

NASA-funded X-ray instrument settles interstellar debate

New findings from a NASA-funded instrument have resolved a decades-old puzzle about a fog of low-energy X-rays observed over the entire sky. Thanks to refurbished detectors first flown on a NASA sounding rocket in the 1970s, ...

Development of new ion traps advances quantum computing systems

(Phys.org) —Research is being conducted worldwide to develop a new type of computational device known as a quantum computer, based on the principles of quantum physics. Quantum computers could tackle specialized computational ...

How to test the twin paradox without using a spaceship

Forget about anti-ageing creams and hair treatments. If you want to stay young, get a fast spaceship. That is what Einstein's Theory of Relativity predicted a century ago, and it is commonly known as "twin paradox".

Could Jupiter become a star?

NASA's Galileo spacecraft arrived at Jupiter on December 7, 1995, and proceeded to study the giant planet for almost 8 years. It sent back a tremendous amount of scientific information that revolutionized our understanding ...
