SOME RECENTLY POSTED ASTRONOMY PICTURES

Above, the Horsehead Nebula as seen recently by The Hubble space telescope. Actually, it's a composite of several pictures taken at different wavelengths.


For comparrison, here's the same nebula as it appeared in the years before we had The Hubble. A big difference, eh?

{A youTube episode of "Through The Wormhole" goes here, as soon as I can persuade Blogger to accept the show}


Here's (above) a recent episode of "Through the Wormhole." It makes the amazing claim that gravity may not exist. If it does exist then where are the gravitational waves predicted by Einstein? They're nowhere to be found. According to this TV show what we call gravity might just be the same thing as the Strong Force operating through Gluon pairs rather than individual particles.

That's an amazing thing to say. In order to explain why gravity is so weak compared to other forces, we've come up with other dimensions, endless bubble universes, and M Theory. What if none of that was necessary to explain what we see? The demotion of gravity from force to something less would overturn a lot of currently believed ideas. Who's right?


Above, a picture of gigantic spouting water ice geysers on Enceladus, a moon of Saturn. It took a while to figure out that the water was coming from within the world and not from canyons on the moon's surface. Now it's widely believed that there is indeed a gigantic liquid ocean under the surface. People are asking the question, "Could Earth's life have began in the warm seas of this world?" Organic molecules from Io are constantly raining down on Enceladus.
