Very Large X Ray Telescope
360 wordsScientists have discovered the closest black hole yet, a mere 1,600 light years from Earth. At the peak of its X-ray output, V 4641 Sgr was the brightest X-ray emitter in the sky. Astronomers call this type of system an X-ray nova because it suddenly becomes a bright source of X-rays, but this object shows characteristics never seen in an X-ray nova. Smith worked on data from this object with MIT principal research scientist Ronald Re millard and NRAO astronomer Robert Hjellming. Black holes har...

Earth Bound Radio Telescopes
998 wordsb) Why are astronomers using radio telescopes looking for far stars instead of a telescope? First of all, what is a radio telescope? The first non-visual spectral region that was used extensively for astronomical observations was the radio frequency band. Telescopes observing at these wavelengths are commonly called radio telescopes. Radio telescopes may be made much larger than optical / infrared telescopes because the wavelengths of radio waves are much longer than wavelengths of optical light...

2,638 wordsTELESCOPE Light and other kinds of electromagnetic radiation coming from the universe outside the Earth must travel enormous distances through space and time to reach observers. Only the brightest and nearest stars can be seen with the unaided eye. To see farther and to clarify and measure what is seen, a telescope is needed. The word telescope is derived from the Greek words tele, "from afar", and skopos, "viewer". Even a simple homemade telescope can clearly show Saturn's rings, Jupiter's band...

Cluster Around The Centre Of The Galaxy
1,915 wordsPart One Brief Descriptions of the Following Astronomers: Walter Baade: Baade was a German-born American, whose work gave new estimates for the age and size of the universe. During the wartime, blackouts aided his observations and allowed him to identify and classify stars in a new and useful way, and led him to increase and improve Hubble's values for the size and age of the universe (to the great relief of geologists.) He also worked on supernovae and radio stars. Milton Humason: Humason was a...

Faint Radio Waves
1,029 wordsIntroduction: There are many fascinating things about the universe and there are lots to learn from it too. Most of the discoveries in outer space were in our solar system and most of them were observed from the human eye aided by telescopes. Is it possible to observe objects from outer space using instruments other than the telescope? Fortunately, we are able to explore other parts of the electromagnetic spectrum using different kinds of observations such as the radio telescope, invented by Mr....
