Montegancedo Astronomical Observatory
Desde el mes de Diciembre se ha puesto en marcha el primer experimento. En este caso el público podrá observar el Sol en el horario establecido. De momento se sigue trabajando en mejorar el observatorio y conseguir un sistema totalmente fiable de modo que el observatorio pueda permanecer abierto sin la presencia de un operador. Por este motivo se ha escogido el Sol como primer objeto a observar. Actualmente para acceder a la interfaz de control del experimento hay que realizar previamente una reserva. El objetivo de este primer experimento es poder observar el Sol en la banda H-alfa y poder distinguir las manchas y protuberancias solares, además de aprender a cambiar los diferentes parámetros de las cámaras para obtener buenas imágenes astronómicas.
Astrobiology - The Hunt for Life Beyond Earth
The Drake equation, formulated in 1961, estimates the number of alien civilizations we could detect. Recent discoveries of numerous planets in the Milky Way have raised the odds. The final step: Multiply the number of radio-savvy civilizations by the average time they're likely to keep broadcasting or even to survive. The equation made perfect sense, but there was one problem. It would be a third of a century before scientists could even begin to put rough estimates into the equation. Nobody thought for a moment that life could ever take hold in such hellish conditions. None of these planets is an exact match for Earth, but scientists are confident they'll find one that is before too long. That's good news for astrobiologists. Moreover, scientists now believe a planet doesn't have to be the same size as Earth to be habitable. A microbe retrieved in 2013 from Lake Whillans, half a mile beneath the Antarctic ice, reveals life's ability to take hold even in the most extreme environments.

Galileanos
Hola Galileanos!! La observación del cielo a simple vista, por estos días, es propicia para identificar objetos y fenómenos poco comunes. En la madrugada del 15 de abril tendremos Eclipse de Luna Llena (lo veremos desde el parqueadero cerrado del Museo de Arte Moderno de Medellín, en Ciudad del Río) y, hace algunos días, hemos disfrutado la vista de Marte sobre nuestro cielo, gracias a las noches despejadas hasta casi las 12:00, cuando el clima de nuevo llena de nubes nuestro campo visible. Esto de la observación es una maravilla, con el ojo desnudo o a simple vista. Video de ScienceCast (NASA) La NASA informa que la distancia de acercamiento entre nuestros planetas es de unos 300 kilómetros por minuto, de modo que las matemáticas traducen la cifra final en una proximidad final de 92 millones de kilómetros a mediados de mes, cuando el fenómeno termine y las cosas vuelvan a sus órbitas elípticas tradicionales. Nos vemos, y felices cielos!

eedwood House Farm is easy to miss. Only a small sign - the bright pink image of a pig - suspended from a fence post hints at anything of significance down the one-way track that leads off the main road. After a few hundred metres of bouncing over mud and gravel, it is the pungent smell that smacks you first. Then, the sound; the squealing, grunting and growls of 5,000 pigs crammed into this corner of rural Staffordshire. A hundred or so piglets are excitedly clambering over each other or snuffling around the muddy floor of the gated outdoor enclosure where they are waiting to be transported for slaughter. Inside the great barns, 500 sows lie side-by-side in pens while their offspring fight for space at their teats.The air hangs heavy with ammonia, so thick it stings the lungs. This is the flagship operation of Midland Pig Producers, which runs nine farms across the country producing 80 tonnes of meat a week to supply Tesco, Marks and Spencer and Asda.

What are RSS and Atom feeds? RSS and Atom news feeds are computer-readable files that summarise new content as it appears on a website. (RSS and Atom are just two different formats that do basically the same thing.) Each feed includes a heading, a brief description of the new content and a link through to the website. Stay in touch with new publishing News feeds are a very convenient way of keeping up-to-date with a large number of websites. ‘ Syndicating ’ content News feeds are also an easy way for other websites to get and display content. How can I get Cambridge Journals Online feeds? You need to install a newsreader on your computer.
