Raytheon, Cessna Receive NASA Sonic Boom Research Grants

(Phys.org)—Sonic booms created by aircraft flying faster than the speed of sound certainly aren't known for being faint, but rather for their loud, make-you-jump startle effect for those who experience ...

Noise can be distracting, especially to a person trying to concentrate on a difficult task. Studying annoying noises helps architects design better building environments and policy makers choose effective noise regulations. ...

(Phys.org)—If human beings are ever to fly faster than the speed of sound from one side of the country to another, we first have to figure out how to reduce the level of sonic boom generated by supersonic ...

EU-funded researchers evaluated control techniques of air flow over aeroplane wings during supersonic flight. The optimal wing design developed should lead to important reductions in noise, emissions and ...

For the last few decades, space scientists have generally accepted that the bubble of gas and magnetic fields generated by the sun – known as the heliosphere – moves through space, creating three ...

Japan is making progress toward developing an advanced supersonic passenger aircraft that could, for example, make a day trip between Japan and Hawaii possible.

Coronal mass ejections (CMEs), emissions of magnetized ionized gas from the Sun, can damage satellites and communication technology, so being able to predict where they are heading and how much energy they ...

(Phys.org) —Saturn's moon Titan might be in for some wild weather as it heads into its spring and summer, if two new models are correct. Scientists think that as the seasons change in Titan's northern hemisphere, ...

For decades, Landsat satellites have documented the desiccation of the Aral Sea in Central Asia. Once one of the largest seas in the world, it shrunk to a tenth of its original volume after Russia diverted ...

UPDATE 16:30 p.m. EDT: The M7-class flare was also associated with a coronal mass ejection or CME, another solar phenomenon that can send billions of tons of particles into space. While this CME was not Ea ...

What people take from nature – water, food, timber, inspiration, relaxation – are so abundant, it seems self-evident. Until you try to quantitatively understand how and to what extent they contribute ...

An Ecuadoran satellite launched last month could collide with the remains of a Russian rocket in the coming hours, the country's civilian space agency warned Wednesday.
