Telescópio espacial Webb

Foto : Hubble site

O telescópio espacial Webb,tém o seu lançamento previsto para 2013.
Espera-se que a "visão" do Webb chegue onde o Hubble ainda não conseguiu
e,se o Hubble nos tém maravilhado com as suas imagens,e as descobertas
que lhes estão associadas,será que podemos imaginar o que o Webb
irá encontrar nas profundezas do espaço?
Onde começa o espaço( e o tempo)?
A foto é de um modelo em tamanho real do Webb,com toda a equipa que lhe
está associada,no Goddard Space Flight Center,em Maryland,nos USA.

Adagio

Vivemos a época da Páscoa,seja para os Judeus seja para os Cristãos.O Adagio de Albinoni plenamente acompanha estes momentos que se pretendem de reflexão,interiorização e renascimento.De tristeza mas,também,de exaltação e libertação.

A beleza do Pulsar 1509,numa foto recolhida pelo telescópio de raios-x "Chandra" .

Reproduzo,em seguida,um texto informativo da NASA,sobre o pulsar 1509

"A small, dense object only twelve miles in diameter is responsible for this beautiful X-ray nebula that spans 150 light years. At the center of this image made by NASA’s Chandra X-ray Observatory is a very young and powerful pulsar, known as PSR B1509-58, or B1509 for short. The pulsar is a rapidly spinning neutron star which is spewing energy out into the space around it to create complex and intriguing structures, including one that resembles a large cosmic hand.
In this image, the lowest energy X-rays that Chandra detects are red, the medium range is green, and the most energetic ones are colored blue. Astronomers think that B1509 is about 1,700 years old and is located about 17,000 light years away.
Neutron stars are created when massive stars run out of fuel and collapse. B1509 is spinning completely around almost 7 times every second and is releasing energy into its environment at a prodigious rate -- presumably because it has an intense magnetic field at its surface, estimated to be 15 trillion times stronger than the Earth’s magnetic field.
The combination of rapid rotation and ultra-strong magnetic field makes B1509 one of the most powerful electromagnetic generators in the Galaxy. This generator drives an energetic wind of electrons and ions away from the neutron star. As the electrons move through the magnetized nebula, they radiate away their energy and create the elaborate nebula seen by Chandra.
In the innermost regions, a faint circle surrounds the pulsar, and marks the spot where the wind is rapidly decelerated by the slowly expanding nebula. In this way, B1509 shares some striking similarities to the famous Crab Nebula. However B1509's nebula is 15 times wider than the Crab's diameter of 10 light years.
Finger-like structures extend to the north, apparently energizing knots of material in a neighboring gas cloud known as RCW 89. The transfer of energy from the wind to these knots makes them glow brightly in X-rays (orange and red features to the upper right). The temperature in this region appears to vary in a circular pattern around this ring of emission, suggesting that the pulsar may be precessing like a spinning top and sweeping an energizing beam around the gas in RCW 89.
