Kepler Space Telescope Has Found a Strange Star.

The Kepler space telescope has discovered a most unusual star in its search for exoplanets a long time, but erratic dimming of the light, – up to 20% dimming, which is *a lot*, over a longer period.
There are several hypotheses investigated, including a swarm of comets, or …. just maybe …. a structure built by an alien civilization.

Now, I remember the buzz a few decades ago, when the first pulsars were detected, and some thought the precision of the pulses had to be artificial but – as it turned out – it was a natural phenomenon of a fast rotating neutron star.

I would not jump to the alien conclusion before every other hypothesis has been thoroughly investigated. It could, however become very exciting if all the “natural” hypotheses would have to be discounted …

Colliding Planets !!

The Spitzer InfraRed Space Telescope, launched a few years ago, has , more or less by accident found the remains of – not one – *but two* rocky planets around a star about 100 light years away.

The two planets, one estimated to be in the order of Earth sized, the other Moon sized , appear to have collided probably a few thousand years ago, very recent in astronomical terms.

This is, as far as I know, the first, however indirect, evidence of Earth/Moon sized planets.

That is not all : A few days ago it was reported that the Kepler Space Telescope, launched this year, had detected the atmosphere of a planet orbiting another star

Exciting times indeed.
