Las razas de perros mas raras en el mundo - 1) Lundehund noruego

1) Lundehund noruego

Es físicamente diferente a cualquier otro: ¡tiene seis dedos en cada pata! La raza fue creada alrededor del siglo XV para la caza del frailecillo, un pájaro típico de Noruega. El sexto dedo fue añadido para aumentar su agarre a las rocas y evitar que se cayera. Otra particularidad está en la unión de sus huesos. Son capaces de girar la cabeza hacia atrás sobre la columna vertebral y de estirar las patas hasta quedar en 90 grados, como los brazos de los humanos.

Explanation: This moon is doomed. Mars, the red planet named for the Roman god of war, has two tiny moons, Phobos and Deimos, whose names are derived from the Greek for Fear and Panic. These martian moons may well be captured asteroids originating in the main asteroid belt between Mars and Jupiter or perhaps from even more distant reaches of the Solar System. The larger moon, Phobos, is indeed seen to be a cratered, asteroid-like object in thisstunning color image from the robotic Mars Reconnaissance Orbiter, recorded at a resolution of about seven meters per pixel. But Phobos orbits so close to Mars - about 5,800 kilometers above the surface compared to 400,000 kilometers for our Moon - that gravitational tidal forces are dragging it down. A recent analysis of the long grooves indicates that they may result from global stretching caused by tides -- the differing force of Mars' gravity on different sides of Phobos. These grooves may then be an early phase in the disintegration of Phobos into a ring of debris around Mars.

Explanation: Following an ancient galaxy-galaxy collision 200 million light-years from Earth, debris from a gas-rich galaxy, NGC 5291, was flung far into intergalactic space. NGC 5291 and the likely interloper, also known as the "Seashell" galaxy, are captured near the center of this spectacular scene. The sharp, ground-based telescopic image looks toward the galaxy cluster Abell 3574 in the southern constellation Centaurus. Stretched along the 100,000 light-year long tidal tails, are clumps resembling dwarf galaxies, but lacking old stars, apparently dominated by young stars and active star forming regions. Found to be unusually rich in elements heavier than hydrogen and helium, the dwarf galaxies were likely born in intergalactic space, recycling the enriched debris from NGC 5291 itself.

Astronomy picture of the day - 2015 November 20 - Leonids and Friends

Explanation: Leonid meteors rained down on planet Earth this week, the annual shower of dusty debris from the orbit of Comet 55P/Tempel-Tuttle. Leonids streak through this composite night skyview from a backyard observatory in southern Ontario. Recorded with camera fixed to a tripod, the individual frames capture the bright meteor activity throughout the night of November 16/17, about a day before the shower's very modest peak. The frames are registered to the fixed field of view, so the meteor trails are not all aligned to the background star field recorded that evening when Orion stood above the southern horizon. As a result, the trails don't appear to point back to the shower's radiant in Leo, situated off the left edge of the star field frame. In fact, some trails could be of Taurid meteors, a shower also active in November, or even sporadic meteors, including a bright fireball with its reflection near the horizon.

Now, it's time to say goodbye - Ciao, ciao, ciao...

CIAO, CIAO, CIAO...
