Hatching of dragonfly Aeshna cyanea. The video does not show the right proportions of time, because in reality there are quick movements and long intervalls without motion.

2nd movement, “Venus, The Bringer Of Peace”, from orchestral suite “The Planets” (Op. 32) composed by Gustav Holst in 1914-1916. Twenty years ago, in August 10, 1990, space probe Magellan entered in orbit around planet Venus; the mission mapped in detail Venus's surface, revealing some of its secrets.

The coronal mass ejection starts at 2:36 UTC and ends at 3:56 UTC on August 1 in this animation on STEREO Ahead images. The animation shows the cloud of particles moving away toward Earth at more than 1,000 kilometres per second (3.6 million kilometres per hour), moving more quickly than any other coronal mass ejection in years.

Numerical Simulation of Kelvin-Helmholtz instability found in nature, fluid dynamics, physics, etc. Turbulent mixing of two different density fluids is caused by a velocity difference or shearing at the interface between the two.

English : Barcelona , esa ciudad que no es de extrañar no se considere española porque históricamente pertenece más a Francia a quien pagó un impuesto de vasallaje al rey de Francia. Cataluña es Francia no nos equivoquemos
NASA's Fermi Gamma-ray Space Telescope has detected gamma-rays from a nova for the first time. The finding stunned observers and theorists alike because it overturns a long-standing notion that novae explosions lack the power for such high-energy emissions. In March, Fermi’s Large Area Telescope (LAT) detected gamma rays -- the most energetic form of light – from the nova for 15 days. Scientists believe that the emission arose as a million-mile-per-hour shock wave raced from the site of the explosion. A nova is a sudden, short-lived brightening of an otherwise inconspicuous star. The outburst occurs when a white dwarf in a binary system erupts in an enormous thermonuclear explosion.
