Supersonic Passenger Travel May Be Coming Closer To Reality
2014-06-18 03:31:45

Karen Northon, NASA The return of supersonic passenger travel may be coming closer to reality thanks to NASA’s efforts to define a new standard for low sonic booms. Several NASA aeronautics researchers will present their work in Atlanta this week at Aviation 2014, an annual event of the American Institute of Aeronautics and Astronautics. They will share with the global aviation community the progress they are making in overcoming some of the biggest hurdles to supersonic passenger...

Scientists Discover How Explosives Respond To Shockwaves
2013-12-12 15:49:37

Lawrence Livermore National Laboratory Lawrence Livermore National Laboratory researchers have combined ultrafast time-resolved experimental measurements with theory to reveal how an explosive responds to a high-impact shock. The work involved advances in both ultrafast experimental shockwave methods and molecular dynamics (MD) simulation techniques, and the combination of experiment and simulation is a milestone in understanding chemical initiation and detonation. When an energetic...

Tycho Supernova Mach 1000 Shock Wave

John P. Millis, PhD for redOrbit.com - Your Universe Online Somewhere in the Universe a star or stellar remnant is preparing to explode. Binary white dwarf systems can build up in mass as the compact object accretes mass from its companion. Eventually, the tiny ball of matter will explode in a brilliant event known as a supernova. The blast can glow for weeks or even months before eventually fading. However, the shock wave from the event will travel through the surrounding medium,...

NASA Focuses On Supsersonic Shockwaves
2013-09-13 16:33:36

Brett Smith for redOrbit.com – Your Universe Online New images released by NASA depict actual shockwaves in vivid colors emanating from a plane flying at supersonic speed. Using a twin telescope and digital camera system on the ground at NASA’s Dryden Flight Research Center, scientists created schlieren images, which show density variations in air and other transparent media. Special illumination in the images mark changes in the density of the air, revealing the shockwaves....

Cassini Catches Solar Wind, Helps NASA Study Particle Acceleration
2013-02-20 14:23:12

Michael Harper for redOrbit.com — Your Universe Online As it floats around the planet Saturn, the Cassini spacecraft recently got a front row seat to what NASA astronomers are calling an “unusual strong blast of solar wind.” Shortly after this “wind” blew by, Cassini began detecting particles which had been accelerated to ultra-high energies. Particles which are accelerated this much are usually found surrounding far away supernovas. This is good news for...

NASA Dryden F/A-18 Will Be Chasing 'FaINT' Sonic Booms
2012-10-26 09:22:14

NASA´s Supersonics Project will embark on its latest effort to soften sonic booms when a NASA F/A-18 aircraft takes to the air in a project called Farfield Investigation of No Boom Threshold, or FaINT, beginning in late October. As the latest in a continuing progression of NASA supersonics research projects aimed at reducing or mitigating the effect of sonic booms, FaINT is designed to enable engineers to better understand evanescent waves, an acoustic phenomenon that occurs at the...

Scientists Explain The Sound In Saturn’s Rings
2012-10-17 19:24:53

Alan McStravick for redOrbit.com — Your Universe Online The theoretical prediction of the existence of linear and nonlinear dust acoustic waves in dusty plasmas was first postulated more than two decades ago by Professor Padma Kant Shukla. Since that early prediction, these acoustic waves have been observed in several laboratory experiments. With that discovery, Professor Shukla´s discovery has transformed the field of plasma physics, even opening up a new interdisciplinary...

Plasma Waves Move Faster Than Shockwaves
2012-07-20 08:07:31

Lawrence LeBlond for redOrbit.com - Your Universe Online The Sun and the dynamic space weather system that envelops the Earth are what researchers are trying to get a better understanding of with the help of Heliophysics nuggets -- collections of early scientific results, new research techniques and instrument updates. More than 99 percent of the matter found in the universe resembles nothing like what we have here on Earth, according to scientists from NASA´s Goddard Space Flight...

Speed Of The Sun 'Shockingly' Slower Than Believed
2012-05-11 04:06:18

[ Watch the Video ] A team of NASA researchers has uncovered new data showing that the sun is moving more slowly through our galaxy than previously believed -- a discovery that suggests a shock wave believed to precede the heliosphere might not actually exist, the US space agency revealed on Thursday. According to Andrew Fazekas of National Geographic News, NASA's Interstellar Boundary Explorer (IBEX) satellite measured the speeds of various interstellar particles along the outer edges...

Explosions of reactive gases and the associated rapid, uncontrolled release of large amounts of energy pose threats of immense destructive power to mining operations, fuel storage facilities, chemical processing plants, and many other industrial applications. To gain a better understanding of what's going on during these explosions, US Naval Research Laboratory research physicist Alexei Poludnenko, and Elaine Oran, senior scientist for reactive flow physics, teamed up with Sandia National...


Word of the Day
vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
