¡Buenos días! Espero que disfrutéis de este vídeo tanto como yo. Primer vídeo musical hecho en el espacio, de la canción de David Bowie “Space Oddity”, por el enorme Chris Hadfield, que acaba de volver a la Tierra después de 5 meses en la ISS.

New Earth-like Planets Found!
Kepler 22b, 69c and 62e are planets approximately 2700 light years from Earth in constellation Cygus. All planets are located in a ‘Habitable Zone’, meaning they’re close enough to their sun to potentially carry liquid water, and host life.
El pequeño punto en la izquierda que podéis ver en esta imagen de Saturno tomada por Cassini… es la Tierra.

The number of places in our solar system that could have ever supported life now stands at 2!
The first, of course, is Earth, because … well, us. According to an awesomely exciting announcement today by NASA and JPL, we can add Gale Crater to that list!
What they found: Curiosity’s rock drill recently uncovered clay-like minerals below Gale Crater’s rusty red surface. These muddy minerals, pictured above, hint at a “Gray Mars” era, when Gale Crater and the ancient stream bed it holds could have been home to intermittent lakes. When the onboard instruments scanned the chemical makeup of the clay, it found carbon, hydrogen, oxygen, nitrogen, phosphorous and sulfur compounds, a group of elements known as “CHONPS” that have to exist in order to create life as we know it. Most importantly, the minerals were pretty neutral in pH and were found in forms that point to a possible chemical energy system (another key ingredient for life).
What remains unknown: This does NOT mean that anything ever actually lived there. But it is the first time that the ingredients for the evolution of microbial life, and the correct conditions to support it, have been directly observed beyond Earth. Mars still has water frozen at its poles, and once had quite a bit of water above and below the surface. The rover will poke around this site, called Yellowknife Bay, for a while longer before heading toward the mountainous center of Gale Crater. There, it will study the multiple layers of rock present on the hillside in order to piece together an even clearer picture of Gale Crater’s muddy, moist, maybe* microbial Martian past.
*Maybe. Just want to emphasize that part.
Un meteorito explota en Rusia antes de tocar tierra.
Ha pasado hoy, y no ha sido el que se esperaba ver pasar cerca de la Tierra. Este vídeo es impresionante, y hay otros muchos ya por youtube.
Os dejo una web donde podéis ver algunos más (aquí).
Me recuerda mucho a un documental que vi hace ya tiempo de un caso parecido pero a mayor escala, que con suerte ocurrió en una región deshabitada en Tunguska, Siberia. Os lo dejo aquí por si os interesa.
