We may not be sending people into space but we can still explore space through the telescopes on and around our planet surveying star upon star looking for answers to the questions that we as a races want answered. Are we alone “Two possibilities exist, either we are alone in this universe or we are not. Both are equally terrifying” Arthur c. Clarke.
As we are restrain by are life spans we use robots and unmanned space craft one of the more famous space telescopes we have is Kepler have systems discovered by it put under the name Kepler. There are many different types of stars which are designated under classes of star from M being the coldest and O being the hottest of the main sequence stars needless to say the hotter the sun gets the further …show more content…
taking a picture of a star with a really big and high definition camera whilst blocking out as much light from the star that the planet is orbiting as the glare from the star alone is enough to block out the already faint planet “because space is big so mind bogglingly big you may think it’s a long way down the road to the chemist but that’s peanuts to space” Douglas Adams , this has many disadvantages such as it only really allows detection of larger e.g. the size of Jupiter. The smaller the object the harder it gets it is to pick out against its parent star. Other methods included in this category is infrared imaging which is used much more than the first method because it can see into the infrared spectrum, this only works if they are very hot planets.
The next lot of methods come under a different category of they are called indirect methods these in some case do not need line of sight on the planet to know it is there.
The first indirect method we will be looking at is call the Doppler method thus method requires observation of the parent star for something call the Doppler Effect/Doppler effect which is described most of the time described (I don’t remember ill just draw it) (Not to scale in any way shape or
