NASA’s Big Kepler Announcement: It’s Not Aliens

NASA announced recently that they would be making a big announcement today about a discovery by the Kepler Telescope. Well, the announcement is that 1,284 planets have been discovered. And what’s really big is that there’s a 99% chance that they are planets. Here’s a graph of the planets that have been discovered so far.

Of course, before the announcement was made, many people were speculating on what the announcement would be. This includes science groups on Facebook. Groups that I would think would know better. You see, this is what people were saying: NASA is going to announce aliens!!!!

First of all, science groups were saying this. Really? Too many science groups are promoting both junk science and hype.

Secondly, NASA is not going to announce aliens when they said they were talking about a Kepler discovery. Kepler is not designed to detect life. It cannot detect life. Kepler deals with detecting planets that cross in front of their stars. That does not include detecting alien civilisations or even life. Further observation is required to study the atmosphere, and even then, we can’t be certain if there’s life.

However, several of the new planets are fairly close to Earth-sized and in the habitable zone of their stars. That is exciting. Those planets will be studied to pinpoint their sizes and atmospheres.

So, relax. No aliens will be discovered by Kepler. I don’t know why people even thought that.
