Comet Siding Spring will brush astonishingly close to Mars later this year – but UMD astronomers say it won't harm three spacecraft orbiting the Red Planet. Instead the spacecraft will give scientists an unprecedented close look at the comet as it nears the sun for the first time. (PRWEB) June 19, 2014 Comet Siding Spring will brush astonishingly close to Mars later this year – close enough to raise concerns about the safety of three spacecraft orbiting the Red Planet. But after...

Jim Banke, NASA The right tool for the job. It's a platitude that is as true for garage tinkerers as it is for the NASA aeronautical innovators who are helping to design future airliners that will cut fuel consumption, reduce polluting emissions and fly more quietly. Yet at least in one area – namely computational fluid dynamics, or CFD – the design tools that helped give us the modern airliners flying today are not expected to be up to the challenge in the future without some...

black hole gravity may be turbulent
2014-06-06 10:03:11

Brett Smith for redOrbit.com - Your Universe Online According to conventional wisdom among physicists, gravity cannot become turbulent. However, new research from the Perimeter Institute for Theoretical Physics has found that gravity can become turbulent, specifically around a black hole, because it behaves like a fluid. “There’s a conjecture in physics – the holographic conjecture – which says gravity can be described as a field theory,” said study author Luis Lehner, a...

A barometer is an instrument that measures atmospheric pressure. The barometer measures pressure exerted by the atmosphere using water, air, or mercury. Through measuring the pressure one can forecast short term weather changes. Evangelista Torricelli is credited with the invention of the barometer in 1643. However, Gasparo Berti unintentionally built a water barometer around the same time. Rene Descartes was also noted as describing an experiment to determine air pressure but there is no...

A Vortex (plural: vortices) is a spinning, often turbulent, mass of flowing fluid. Any spiral movement with a closed streamline is considered vortex flow. The speed and rate of rotation of a vortex is always greatest at the center, with progressively decreasing speed away from the center. The fluid pressure is lowest in the center of the vortex, and rises further from the center (Bernoulli's Principle). The core of a vortex is sometimes visible due to a plume of water vapor caused by...

Turbulence (or turbulent flow) is characterized by chaotic, random property changes. Turbulence occurs with low momentum diffusion (spreading of atmospheric properties), high momentum convection (vertical transference of atmospheric properties), and rapid variation of pressure and velocity in both space and time. A flow that is not turbulent is known as laminar flow. A vortex moving at low speeds will most likely cause laminar flow, and as speeds increase a transition is made to turbulent...

Comet -- A comet is a small body from the outer reaches of the solar system similar to an asteroid but composed of ice. Often described as "dirty snowballs," they are composed largely of carbon dioxide ice, methane ice, and water ice with a mixture of dust and small stony aggregates mixed in. Comets are thought to be small pieces of debris left over from the formation of the solar system, representing a sample of the original composition of the nebula that condensed to form the Sun and all...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
