Physicists Confirm Possible Discovery of Fifth Force of Nature
Recent findings indicating the possible discovery of a previously unknown subatomic particle may be evidence of a fifth fundamental force of nature.

Vortex Laser Offers Hope For Moore’s Law
The optics advancement may solve an approaching data bottleneck by helping to boost computing power and information transfer rates tenfold

<p>This artist’s impression shows the strange object AR Scorpii. In this unique double star a rapidly spinning white dwarf star (right) powers electrons up to almost the speed of light. These high energy particles release blasts of radiation that lash the companion red dwarf star (left) and cause the entire system to pulse dramatically every 1.97 minutes with radiation ranging from the ultraviolet to radio.</p>

White Dwarf Lashes Red Dwarf With Mystery Ray
New type of exotic binary star, a rapidly spinning white dwarf star is powering electrons up to almost the speed of light.
<p>Turbulent atmospheric flows above the storm produce both gravity waves and acoustic waves. Gravity waves are much like how a guitar string moves when plucked, while acoustic waves are compressions of the air (sound waves!). Heating in the upper atmosphere 500 miles above the storm is thought to be caused by a combination of these two wave types 'crashing' like ocean waves on a beach</p>

Jupiter's Great Red Spot Heats Planet's Upper Atmosphere
Jupiter's Great Red Spot may provide the mysterious source of energy required to heat the planet's upper atmosphere to the unusually high values observed.

Knots In Chaotic Waves
New research, using computer models of wave chaos, has shown that three-dimensional tangled vortex filaments can in fact be knotted in many highly complex ways.

318 Times as Massive as Earth

by Anton Skorucak and

Planet Jupiter: Space Telescope Science Institute / NASA What is 318 times more massive than Earth? Jupiter, the fifth planet from the Sun (next in line after Earth and Mars). Jupiter is the largest planet in our Solar System. If you decided to take a Boeing 777 for a trip around Jupiter, it would take you over 21 days just to circle once around its equator and that is without the refueling stops. However, if you ride with one of Jupiter's violent wind streams, which can blow as fast as 600 kph (372 mph), your trip can be as short as 13 days (it is still quite a trip!). If you ever do take an airplane for a trip around Jupiter, make sure to aviod the Great Red Spot (lower right corner of the image). The Great Red Spot is actually a tornado so big that it could hold two Earths and which has been active for at least last 300 years!

Jupiter got its name from the Roman God: Jupiter Optimus Maximus (all-good, all-powerful, the God of the Gods – Zeus is the Greek equivalent). Jupiter is mostly gas, about 90% Hydrogen and 10% Helium, with some traces of methane, ammonia, water and rock. Its core is most likely solid rock, covered with a layer of liquid metallic hydrogen. Because the pressure close to the core is so great, hydrogen becomes liquid. Not only that, its protons and electrons get ionized – they start existing individually in this liquid (as opposed to being grouped into atoms). This hydrogen 'soup' is actually a conductor – that's why it is called metallic. Jupiter has 28 known moons, most of which are named after Zeus's lovers (Ganymede, Io, Europa, etc.)

The Color of The Sunset

Color in the form of pigment does not exist in the atmosphere. Instead, the color we see in the sky results from the scattering, refraction, and diffraction of sunlight by particles in the atmosphere, ...
