behaviour 5 Organizations Equipment A pelican flying moves steadily enough for it to be followed with a pair of binoculars It is useful to have a good pair of binoculars to help to see birds that are far away more clearly. Scopes or telescopes can also be used. These give much greater magnification than binoculars (making the birds look much bigger)‚ but they need to put on a tripod because they cannot be held steady by hand. They are useful for looking at birds that stay in one place

Galileo and how others perceived his explorations. After his creation of the telescope and the discovery of the rough side of the moon‚ the Copernican Revolution began. This is when the argument of the world spinning on an axis and not standing still came into play. “Galileo answered the observational astronomical objections by showing that the empirical consequences implied by Copernicanism were indeed visible with the telescope‚ although still invisible with the naked eye” (1).

LIFE CYCLE OF A STAR Stars are formed in nebulae‚ interstellar clouds of dust and gas (mostly hydrogen). These stellar nurseries are abundant in the arms of spiral galaxies. In these stellar nurseries‚ dense parts of these clouds undergo gravitational collapse and compress to form a rotating gas globule. The globule is cooled by emitting radio waves and infrared radiation. It is compressed by gravitational forces and also by shock waves of pressure from supernova or the hot gas released

‘Solar panels’‚ as they are usually called‚ are now quite a common sight here on Earth‚ but they were first used in space in 1958 to power the ‘Vanguard’ satellite. Principles of solar satellites In photovoltaic cells‚ such as the Hubble Space Telescope silicon solar cell shown here‚ the basic materials‚ the doping and the shape of the junction are chosen in such a way as to increase their capability of transforming the light energy into electrical energy. Each cell is capable of producing a small

the observatory room. I speculated around and try to hold my intellectually excitement from being baffled by the astronomical instrument to which the 24.5in telescope was center in the middle of the room. Reminiscing back to when I was walking home at night‚ I remember of seeing an unusual star unlike any other. I slid over to the telescope and embark to look at the constellations but I notice that one of the stars west of Orion’s Belt started to slowly moves towards our planet. As I started to zoom

and even average people have wondered if there is such thing as life on other planets. Many dedicate all of their time to researching extraterrestrial life. Some believe researching something we have no proof of is a waste of time. Modern day telescopes have detected Earth-sized planets orbiting nearby stars. An ancient Martian rock shows signs of life‚ and scientists wonder if Jupiter’s moon Europa contains life in its oceans. The idea that there is even a tiny hint of life that we share the universe
