Rob Gutro, NASA Goddard Space Flight Center [ Watch the Video: Space Station Cameras And Crew Capture Views Of Tropical Storm Arthur ] When NASA's Aqua satellite passed over Tropical Storm Arthur on July 2 at 2:50 p.m. EDT on July 2, it saw a cloud-covered eye as the storm was on the way to becoming a hurricane. This visible image of Tropical Storm Arthur was captured by the Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Aqua satellite....

Difference Between Solids And Liquids Explored Through New Pitch Drop Experiment
2014-07-03 08:17:15

Queen Mary, University of London Physicists at Queen Mary University of London have set up a new pitch drop experiment for students to explore the difference between solid and liquids. Known as the 'world's longest experiment', the set up at the University of Queensland was famous for taking ten years for a drop of pitch – a thick, black, sticky material – to fall from a funnel. Publishing in the journal Physics Education, the design of QMUL's trial is different to both...

Malaspina Expedition Finds World's Oceans Littered With Microplastics
2014-07-01 11:18:07

Brett Smith for redOrbit.com - Your Universe Online The result of a 2010 ocean voyage around the world, a new study has found evidence of tiny “microplastics” in five large accumulations across the world -- accumulations that match the five large open-ocean currents called gyres. According to the study, which was published in the Proceedings of the National Academy of Sciences, large amounts of these microplastics could be moving through the marine food chain or sinking to the ocean...

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...
