It takes a real Trekhead to make the connection, but Who Mourns for Adonais? comes to mind.

A small, dense object only 12 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 that 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 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 decelerates rapidly 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.

Nice image. Good trek episode.

*confesses to being a real Trekhead*

Lovely image, although I just set my background to the triple-galaxy shot from the Hubble.

I'm definitely coming back as a pulsar in the next lifetime.

Bah, who needs that kind of pressure? XD

Then I must be a huge dork, cause that made me laugh.
