Interstellar medium

Christiaan Huygens was a Dutch mathematician and scientist, lived from April 14, 1629 – July 8, 1695. He was one of the leading scientists of his time and is best known as an astronomer, physicist, proabablist, and horologist. His contributions to experimental and theoretical physics were most notably the discovery of Titan, invention of the first pendulum clock, and the earliest theory about the nature of light. His great contributions are of great significance and so he deserves to be chosen…

XMM Newton:- The XMM-Newton (X-ray Multi-Mirror Mission or High Throughput X-ray Spectroscopy Mission) is an orbiting X-ray observatory launched in December 1999 by ESA (European Space Agency). ). XMM-Newton is the biggest satellite ever built in Europe. It is used for the detection of soft portion of the electromagnetic spectrum (100 eV to 12 keV).Using its large collecting area and highly eccentric orbit, it is making long observations of X-ray sources with extremely high sensitivity. It is…

In September of 1985 Kroto, Heath, O’Brien, Curl, and Smalley were investigating sources of the long carbon chain molecules in the interstellar medium and how they might be related to soot formation.1 Smalley developed a laser vaporization cluster beam apparatus that allowed for the mass-spectrometric study of stable clusters formed in a helium-entrained plasma produced by a pulse of laser aimed on at a solid target.2 This experimental technique was a very important discovery to cluster science…

second. An important part of our visible universe are stars. A star is born when atoms of light elements are squeezed under enough pressure for their nuclei to undergo fusion. All stars are a result of force: the force of gravity compresses atoms in interstellar gas until the fusion reaction begins. Stars come in different sizes. The smallest star is called the M- type or the M star. They are just big enough to initiate nuclear fusion at its core. If they were smaller, they would be brown…

The space shuttle in which the crew sat with the utmost anxiety consisted most importantly of the Orbiter vehicle, fundamentally considered by one Gaston (1991) as the brains and heart of the spaceship. Chyu & Cavin (1978) also described it that it contained pressurized crew compartment in which sat seven enthusiastic team members ready to ascent into the parts unknown. At the forward fuselage of this orbiter…
