Trickle of Planet Discoveries Becomes a Flood
Alien worlds, once hidden from knowledge, are now being discovered in droves, stunning astronomers with their unique features and sheer numbers. The discoveries are so common that more and more don’t even get reported outside scientific circles.
Take the announcement at the end of May of a massive planet, dubbed TrES-3, that zips around its star in an amazingly rapid 31 hours, giving the planet a 1.3-day year. Astronomers issued a press release, but you might not have heard about it because the discovery was so overshadowed by other planet announcements and barely received news coverage.
“It’s pretty routine now,†said Alan Boss, a planet formation theorist at the Carnegie Institution of Washington. “Most planets that are found are not deemed worthy of a press release because they are sort of becoming ‘one more planet.’â€
The total is now more than 200 extrasolar planets confirmed. And this is the tip of the iceberg in planet finds. Astronomers have more tools than ever, and technology is so advanced that planet discovery has become almost mundane.
The regularity of planet finds, luckily, is buffered by the wild variety in the discoveries themselves, including the following contrasts: nascent worlds of just a million years versus those that are billions of years old; hot gas giants and icy Neptune-like orbs; planets that whip around their parent stars with cosmic speed and others that seem to creep at a slug’s pace; and planets orbiting double-stars, red-dwarf stars and even so-called failed stars.
sounds pretty awesome to me. It would probably take a while to get there.
Very cool. I'm certain there is so much life out there, I just wish we had the technology to go pay them a visit!
If only we had something like Nomad to go and be able to tell us if life was out there...actually, maybe not something exactly like nomad
