Helium

The very idea of planets orbiting around stars would have shattered the views of many people throughout history. After the Copernican revolution taught us that the Earth is not at the center of the universe but rather planets orbits the Sun opened up the possibility that planets might also orbit other stars. About two decades ago, a new scientific revolution began with the first discoveries of planets orbiting around other stars, called exoplanets. An exoplanet, is any planet that orbits a star…

of no were, but from the big bang. Stars are the main structure to making new elements. The way stars do this is at the core of giant stars it is extremely hot around 200,000,000 to 10,000,000,000. That is hot enough to start to fuse hydrogen into helium. This is still not hot enough to start to fuse atoms into more complex stages. Red…

Humanity has an inherent drive for superior understanding of our Solar system and to find environment similar to that of planet Earth which could contain life. As consequence, there have been several space missions to analyse climate, assess data and search for geological evidences of life. With net expenditure of approximately three billion dollars, the Cassini-Huygens space mission to Saturn system was a joint assignment among finest space agencies; National Aeronautics and Space…

Origins The Voyager program began in the 1965 with Gary Flandro’s discovery of a rare planetary alignment of Jupiter, Saturn, Uranus and Neptune that would occur in 1977. This alignment occurs only once every 175 years. The Grand Tour as the program was called had launch windows between 1976 and 1980. The original idea of the Grand Tour was to send four probes to ultimately visit every planet in our outer solar system. In 1971 funding for the Grand Tour program was canceled in the 1973 NASA…

The Solar System By Krishiv There is always something that you are pondering about. From the periodic table to the circulatory system. But did you know that the majority of people wonder about the Solar System? It is the final frontier, or the one thing that is not fully discovered. There are many unique masses in the Solar System. They range from planets like the earth to rocks such as asteroids, comets, and meteors. But one thing is for certain… every mass has to orbit the sun.…

From this data you can find the total number of electrons, the total number of shells and subshells, as well as how many electrons are in each shell. The large number (the one in 1s2 ) will tell you the shell that the electrons are in. For example, helium (He) has one shell, so its electron configuration is 1s2. Furthermore, the electron configuration tells you what subshell each of the electrons occupy. The subshell is the letter next to the larger number. You will see subshells S, P, and D on…

Intermolecular Forces Intermolecular forces are the result of attractive or repulsive forces between atoms, molecules or ions, primarily as a result of electrostatic attractions; these forces act between discrete molecules. Intermolecular forces are weak forces but without them life as we know it would not be possible: water vapor would not condense into its liquid (or solid forms) if its molecules did not attract each other, and all matter, in fact, would exist as gases. The physical states…

Performance Art has been a active sector of art in the past century. The origins of this kind of art started in the mid-1950s and has only grown larger. The movement of visual art to a more conceptual, somatic experience was most prominent with the rise of Happenings and the Fluxus movement. Art, as demonstrated by these movements was more than an experience separate from the viewer, but instead a holistic experience that included both mind and body. These movements allowed more interaction…

Sleepless nights spent ruminating and regurgitating past events all the while ruing their aftermath often drained Surina the next morning; nonetheless, on the first full day in space, she awoke restored. Certainly, her restful sleep was not entirely due to the profound physical exhaustion from the lift off to space. Rather, after her consciousness roamed amongst the stars, she gained a fresh perspective that allowed her to rest from the burden of her sorrows for the first time in many years.…

The calendars mark 2100. Another year closer to the end. Outside the temperature is 113℃, the usual for July in Dallas. In the news, reports about the decrease in freshwater availability has become the norm. Various animals have gone extinct, plants are unable to thrive in any country because of extreme droughts, and the population has began to decline steadily all over the world. A few scientists shared their ideas on how to keep humanity from vanishing. But many know that the end of the Earth…
