The Milky Way is gobbling up the stars in the grouping we call Sagittarius. We see the stars the way they looked millions of years ago, but sometime in the future, Sagittarians will no longer have a star symbol to call their own.

David Whitehouse writes in BBC News Online that astronomers have learned that our Milky Way is devouring the nearby Sagittarius galaxy, which is 10,000 times smaller in than our own. “It’s clear who’s the bully in the interaction,” says astronomer Steven Majewski “If people had infrared-sensitive eyes, the entrails of Sagittarius would be a prominent fixture sweeping across our sky.”

David Whitehouse writes in bbcnews.com that astronomers have found a planetary system that’s similar to ours, with a big, Jupiter-like planet circling a Sun-like star. Jupiter absorbs most of the meteor impacts that come our way, and is one of the reasons life can exist on the Earth. Of the more than 100 planetary systems we know about, this is the one that is closest to our own.

Although astronomers have only seen the largest orbiting planet so far, they think it’s likely that there are smaller planets, like ours, in the inner orbits. The solar system is 95 light-years away, which is close in astrological terms. This means that if we could travel at the speed of light, we’d reach it in about 100 years.

What many people don’t realize is that we humans can thank Jupiter that we’re here. The huge planet protects the rest of the planets in our solar system by absorbing many of the blows that come our way from comets and asteroids. Asteroids get past it occasionally?like the one that wiped out the dinosaurs–but these extinction events would have happened much more often if it wasn’t for our protector Jupiter.

Now scientists have found another scientists have found a planetary system that looks similar to ours, complete with a huge protector planet. This means there could be an Earth-like planet orbiting a star in an inner orbit.
