Was there some new invention? TELE.....?

All these years and tech.....

We now know that all we learned in school regarding planets and stars has a large family addition.

WOW /\/\ ok so why didn't we find these planets and all there was to follow in the past?

Was the telescope not power full enough or are we going to believe they just happened to appear?

Educate me please?

    There was a time when people in Europe didn't know America existed.

    Then along came More Advanced Technology and sailing ships got even better.

    Eventually a guy got all the way round the world.

    Years later, thousands of people crossed the Atlantic. It was old hat.

    In 1781 it got even better for finding new things. William Herschel found Uranus, the first planet that wasn't known about before.

    All the others could be seen by the naked eye and were known about for thousands of years but Herschel used a telescope he made himself....a 6-inch Newtonian reflector....here's an exact copy of it


    Uranus had actually been seen and recorded before his discovery but it wasn't known then that it was a planet and no particular interest was shown in it. It's only just visible by eye but the air has to be very clear.


    Now there is a new kind of telescope, up in space. It's called Kepler, after a very important planetary astronomer, the guy who worked out Keplers Laws of Planetary Motion.

    It can see very minor changes in a star's light and measure them and time them and so detect planets going in front of a star very far away.

    Now there are hundreds of those planets that are known about but not in much detail. As the resolution of similar telescopes gets better over the years so will the detection rate of new planets and the amount of detail that can be found out about them.


    We still get a problem with the number 26 bus though.

    Marzyparzy can wander over Mars and send pictures back but some of us have to cycle to work to get clocked in before 7am cos the first bus goes at 7.30....when it runs.

    Aaaahhh, progress...........

    Until the eighteenth century, no planets were known beyond Saturn. Uranus had been seen many times but was thought to be a star. It was only when it was found to be moving that it was realised that it wasn't, and then it was thought to be a comet. It is, however, visible to the naked eye.

    Neptune was discovered when it was found that Uranus didn't quite follow the orbit it should, but again it had been observed by telescope even in the early seventeenth century and mistaken for a star. Later, it was realised that it was in the right place to pull Uranus about slightly, and it was discovered as a planet in the nineteenth century.

    However, there have indeed been larger telescopes and in particular the Hubble Space telescope more recently.

    Yes, the new invention is the Kepler Space Telescope

    It is able to measure planetary transits on several thousand stars at the same time.

    It was launched about six months ago and in its first three months it discovered over 500 planets, latest count is 1500 with 700 confirmed.

    Look it up on google, it is too complicated to describe here in a paragraph or two.

    I believe it all started with a lens.

    A piece of deformed glass that magnified things.

    Galileo put together the first working telescope and found that Saturn had ears.

  • If you are talking about exosolar planets then we now have better radio telescopes but also new methods of detecting those planets.
