Black Holes Peters 1 Ron Peters Dr. James R. Pierce CP English 2 20 April 2000 Black Holes A Black hole is a theorized celestial body whose surface gravity is so strong that nothing, including light, can escape from within it's surface. Gravity is the key to a black hole's immense power. The black hole's strong gravity keeps captured material from escaping. For example, if Earth were the same mass it is now but had only one-fourth its present radius, the escape velocity of someone standing on its surface would be twice what it is now. Black holes have a power far greater than our minds can imagine. This report will go into further discussion on these massive holes in space. Now, though, astr ...

Black Holes Black Holes There are many strange and wonderful phenomenons being discovered throughout our Universe. One of the most intriguing is the concept of a black hole in space. Astronomers have discovered a black hole just 1,600 light years away from Earth. The National Radio Astronomy Observatory cataloged this black hole in the constellation Sagittari on a star called V4641. A black hole is one form of a dead star. A star has three choices when it dies, it can: shrink until it is a white dwarf, shrink until it is a neutron star, or keep on shrinking until it is a point in space with an infinite density known as a black hole. A black hole is an extremely dense outer space body that ha ...

Black Holes On December 3, 1995, astronomers using the Hubble Space Telescope identified a black hole in the galaxy NGC 4621, located 100 million light-years from Earth in the direction of the constellation Virgo. This is the second super-massive black hole that astronomers using the Hubble Space Telescope have found. Astronomers believe that the mass of this black hole is about 1.2 billion times the mass of our sun, but it is concentrated in a space that is not any bigger than our solar system There are two puzzling questions that astronomers are trying to answer. The black hole is fueled by the galaxy and its 800 light-year-wide spiral disk of dust. Before the discovery of this black hole, ...

... or real, existing ones. The singularity in the this hole is more time-like, while the other is more space-like. With this subtle difference, objects would be able to enter the black whole from regions away from the equator of the event horizon and not be destroyed. The reason it is called a black hole is because any light inside of the singularity would be pulled back by the infinite gravity so that none of it could escape. As a result anything passing beyond the event horizon would dissappear from sight forever, thus making the black hole impossible for humans to see without using technologicalyl advanced instruments for measuring such things like radiation. The second part of the name ...

... commands. The rest of MS-DOS consists of a number of utility programs. Although DOS had cornered the PC market, UNIX was still dominant on the larger workstations. The birth of UNIX in 1969 provided the world with its first modern operating system. An interactive multi-user operating system, UNIX was initially developed by programmers for their own use. Working for Bell Laboratories, Ken Thompson and Dennis Ritchie created UNIX as an operating system for the PDP-7 computer. Designed as a simplification of an operating system named Multics, UNIX was developed in Assembly language, a primitive computer language specific to one type of machine (Osiris, 1). However, Thompson developed a new ...

- Eileen Collins And Chandra Observatory - 492 words
Eileen Collins And Chandra Observatory A hydrogen fuel leak, which could have caused an engine shutdown, costly delays on the launching pad, and a year of technical difficulties didnt stop the successful launch of the $1.5 billion Chandra X-Ray Observatory on the Space Shuttle Columbia. Nor did it stop Eileen Collins, 42, from becoming NASAs first female commander ever after 95 missions. Collins, who has logged over 5,000 hours of airtime in thirty types of aircraft and 537 of those hours in space, served as pilot in her last two missions in 1995 and 1997, and felt well prepared to handle anything. So, when a short circuit occurred, as Commander, Collins braced for every possible emergency, ...

- Hypernova - 828 words
Hypernova Mysterious Blast, Hypernova Gamma-ray bursts (GRB) have left astronomers scratching their heads since the late 1960s when they were discovered by U.S. military satellites. Part of the mystery began to unlock when astronomers at Northwestern University detected the first observational evidence for the remnants of hypernovae, explosions hundreds of times more powerful than supernovae, last year. Hypernovae may be the possible source of GRBs, making them the most energetic events known in the Universe besides the Big Bang. Northwestern astronomer Daniel Wang identified two hypernova remnants in galaxy M101, also known as the Pinwheel galaxy some 25 million light years away, in April 1 ...

- Observing Stars - 1,341 words
Observing Stars Observing Stars Our view of the sky at night is possible because of the emission and reflection of light. 'Light' is the better-known term for the electromagnetic spectrum, which includes waves in the visible, ultra-violet, infra-red, microwave, radio, X-ray and gamma-ray regions. The scale of the spectrum is so large that no region is distinct, several overlap each other. Each of these regions in the electromagnetic spectrum represent transverse waves, travelling as electrical and magnetic fields which interact perpendicularly to each other, with different ranges of wavelength. The magnetic field oscillates vertically and the electric field horizontally, and each field induc ...

- Planet X - 577 words
Planet X Planet X Is Pluto really a planet? Researchers have been trying to determine whether Pluto is really big enough to be a planet. Over the last few years, the gathered information on Pluto and the discovery of an increasing number of other objects in the outer solar system have been discussed within a group of astronomers (called minor-planets). The planet Pluto is not given the respect of other planets and some have designation to be changed to minor planet. Astronomer Brian Marsden of Harvard Smithsonian Center said if Pluto were discovered seventy years ago, it would be considered a minor planet number. A minor planet is a term used to describe asteroids and most astronomers agree ...

- Quasars - 1,856 words
Quasars Since their discovery, the nature of quasars has been one of the most intriguing and baffling problems as evidenced by the following quotations: the problem of understanding quasi-stellar objects is one of the most important and fascinating tasks in all physics - G.Burbidge and Hoyle. The quasar continues to rank both as one of the most baffling objects in the universe and one most capable of inspiring heated argument - Morrison. The redshift problem is one of the most critical problems in astronomy today - G. Burbidge. Quasars still remain the profoundest mystery in the heavens - Hazard and Mitton. The conventional interpretation of the spectral lines observed in quasars is based on ...

Quasars And Active Galaxies Amy A. Zeleznik Peter Anderson GSC 158 11 November 1999 Quasars and Active Galaxies The astronomical world is full of phenomena beyond the average person's imagination. The technical tools and analytical methods astronomers use are very complex. The enormous numbers and distances are mind boggling. Theories behind astronomical phenomena are based on yet another theory. In order to understand the concept of quasars and active galaxies, one must first have a feel for the astronomical numbers involved. Secondly, a basic knowledge of the tools of the trade, and finally, a working knowledge of astronomical jargon. Once there is a working knowledge of the aforementioned ...

Seti Bertrand Russell wrote, There are two possibilities. Maybe we are alone. Maybe we are not. Both are equally frightening (Jakosky 1). The question of life in the universe is one that leaves many in a state of bewilderment. It becomes even more interesting when it leads to another question that of intelligent life in the universe. Finding other intelligent civilizations among the interstellar space would greatly affect every aspect of our existence. Conversely, not finding such a civilization would force us to examine the purpose of our own existence. To help answer the question, astronomers and scientists set up a program in search for extraterrestrial intelligence. This program, or SET ...

- The Search For Other Worlds: Extrasolar Planets - 1,258 words
The Search For Other Worlds: Extrasolar Planets Earths Beyond Earth: The Search for Other Worlds In early 1990, the first extrasolar planet was detected, surprising everyone by its strangeness. More planets have now been discovered outside our solar system than in it. These planets present many great mysteries to the astronomical world. Extrasolar planets are planets that exist outside our solar system; they are orbiting a star other than our Sun. So far, eighteen have been found, all of them defying well-established theories about planets and how they operate (Winters, 46). As Stephen Maran said, The new discoveries remind us that ignorance is not just bliss, it is also a lack of imaginatio ...

- V Chip Act - 1,181 words
V Chip Act In the process of unbridling the burdened telecommunications industry, Congress somehow forgot itself and managed to regulate a new blossoming business. This industry was one that was a true and unadulterated free market. It is the Internet. This market place, which resides everywhere yet nowhere in a place called cyberspace, deals in one thing: information. Each day millions of people trade uncountable letters, memos, posts on newsgroups, photographs and innumerable conventional and unconventional information. This is done at the rate of millions of gigabytes each hour. Nevertheless, tucked away under Title V of the otherwise agreeable telecommunications deregulatory law, is a me ...

- Why Space - 1,902 words
Why Space? How does space exploration and an organization like NASA (National Aeronautical and Space Administration) benefit the United States? The formation of NASA to monitor and explore space has served the United States by supplying us with advancements in medicine, military defense, consumer products and the citizens of all participating countries a sense of pride in their countries. Space exploration has evolved from being a source of bragging rights during the cold war to a tool to develop faster ways of communication and scientific breakthroughs that are used to cure and/or prevent diseases. The United States has become a world power by using NASA to develop ways to defend the USA as ...
