The magic touch.

Ever since I was a small child, the idea of space travel has fascinated me. I can remember back in the 60's, watching the last of the Mercury missions, through the Gemini and Apollo programs. Like every other American (as well as the rest of the world) in that hot summer of July, 1969, our family watched in awe as two human beings stepped foot on the moon. My parents let me stay up late that night when Neil Armstrong planted his booted foot in the soil, and the whole world became a bit smaller. I also remember, but not totally comprehending the tragedy of two years earlier, when three astronauts, Gus Grissom, Ed White, and Roger Chaffee died in a launch pad fire on Apollo 1.

The Challenger and Columbia disasters. I remember where I was when they happened. For Challenger, I was working, and had just dropped off a patient at the hospital when I heard it on the radio in the ambulance. For Columbia, it was waking up that morning to the horrible news that it had happened again.

It was this interest in the space program that pushed me towards the realm of science fiction, both in print, and in the movies and TV. I fully remember the first sci-fi book I ever read, "The Andromeda Strain." While there were some things in it at the time that were hard for a 10 year-old to grasp, I read it, and read it, over and over again until I got it. From TV, it was the the cheesy stuff, Fireball XL-5, Space, 1999, and even some of the original Star Trek series (not all of them Cake, so don't kill me) to more polished shows such as Babylon 5, and the recently ended Battlestar Galactica, where the ideas that science fiction presented allowed me to dream beyond the confines of my earthly home, and in some ways, helped me to push my own dreams forward.

Then of course, there is Blade Runner. I would be remiss in not mentioning the inspiration for this blog, as well as a movie that had a profound impact on me. It still inspires me to this day.

The unmanned missions to other planets; Pathfinder, Viking, the two current Mars rovers, just to name a few. Then, there's Hubble. I think that with all the accomplishments that other unmanned probes have to list, for me, nothing stands out like Hubble. Its eye has opened up the universe in ways that awe like no other. However, there is another telescope that has given Hubble a run for its money; the Chandra X-Ray observatory. It was this space telescope that inspired me this week, and just makes your jaw drop. It was this picture in particular, that makes me realize how insignificant, and how special we are as humans on this planet:

How incredibly amazing is this? It was labeled the "Cosmic Hand," for its obviously weird similarity to a human hand. The first thing that jumped to mind was Michelangelo's painting in the Sistine Chapel of God reaching out to Adam to give him the spark of life.

In reality, it is a nebula created by a dying star, a pulsar, seemingly touching another nebula. Though the two are far apart, they are cosmic neighbors. In any case, it is a example of the pure beauty and violence that the universe can offer.

Oh brave new worlds.

Sometimes we take our place in the universe just a tad for granted. As humans, we tend to be just a bit self centered, forgetting that we are really just part of a vast cosmic entity. Are we alone? Who knows, but we just got one step closer to that answer.

It seems that for the first time, scientists have actually photographed planets orbiting not just around one, but two stars. While we have known since about 1995 that there are other planets ("exoplanets") that orbit other stars, detecting them has been done by very indirect means. Now, the holy grail of planetary astronomy has been achieved, actually being able to see these planets with a telescope. Hubble was one of the one's used:

Yep, that little dot in the circle is a planet orbiting the star Fomalhaut. It's apparently just a baby planet, only 60 million years old, in a star system only 25 light-years away. This is practically around the block in astronomical terms. Read the article for the information on the other star and its three, count 'em three planets, that orbit it.

So get your hyperdrive engines tuned up, we're taking a road trip to Fomalhaut! Oh, and bring something to snack on please, and go to the bathroom first.
