Elliptical galaxy

Introduction Delphinus is a constellation that often passes by the watch of astronomers due to its limited size, however this little wonder has fascinating stars that captivate your attention when you take the time to focus upon it. Location South and away from the Milky Way's band lies the constellation Delphinus the Dolphin. This tiny grouping of stars lies in the transition zone from that of the summer star filled skies to that of the sparse autumn skies. Once you have located Delphinus…

If it was found out that other galaxies are not moving further, and further away from us quickly.. This would cause the Big Bang Theory too lose its credibility. Also if many other pieces of evidence were found out to be untrue , I believe this theory would lose much of its credibility. The first part of this theory, I will be discussing my main point, which is whether galaxies are moving away from us or not and at what speed. According to Hubble's law, the universe has been expanding since…

Ejnar Hertzsprung and Henry Norris Russel developed a vital tool used to study stellar evolution, a scatter graph that plots a star’s spectral type respective to their absolute magnitude, which is the observational Hertzsprung-Russel Diagram, or the temperature of stars relative to its luminosity, the theoretical H-R diagram. Stars have specific evolutionary stages based on their initial mass, dictating its internal structure and means of energy production. The phases in stellar evolution…

Hitching a Ride on a Light Beam Physics is the most fundamental of the sciences, undergirding astronomy, chemistry, geology, biology, and—absent some paradigm-shattering revelation—human thought and action. Its analytical methods and machines have plumbed the unknown and the inaccessible, from the submicroscopic confines of the atomic nucleus to the billowing expanse of the observable universe. Physics has superseded our biochemically mediated perceptions of the world, replacing qualitative…

Jupiter is the fifth planet out from the sun, and is the largest planet in our solar system. In addition, the planet is primarily made of gases, therefore it considered a “gas giant”. The 142,984 km planet’s atmosphere is made mostly of hydrogen and helium gas. Therefore, there is no solid ground on Jupiter, so the surface is considered the point where the atmospheric pressure is equal to that of Earth. The effective temperature, or “the temperature of an object calculated from the radiation it…

Testing the Validity of the Approach of Using Hydrogen and Helium Emission Spectra with the Rydberg Equation to Determine the Ionization Energy of Helium Michelle Plavnik Department of Chemistry, Emory University, Atlanta, GA, 30322, United States PAGE 2 ABSTRACT: The purpose of this lab is to determine how accurate the Rydberg equation is at modeling helium transitions and finding the ionization energy from those transitions. To accomplish this aim, the spectra of hydrogen and helium were…

The star outside your spaceship's windshield is a spectacular sight. HR 5171 A is a fireball 1,300 times larger than the Earth's sun. It's so big that if it were in our sun's position, it would swallow up Earth beneath its 10,000°F surface. To look at it from your spaceship, you have to wear special goggles--this star is almost a million times brighter than our sun. As you watch HR 5171A burn, you notice something strange. An object is peeking over the horizon, growing larger and larger. It's…

ALMA looks to the heavens at wavelengths of millimeter and submilímetro (submillimeter light has slightly shorter wavelengths than millimeters light, whose wavelengths are measured in millimeters). These ranges fall along the boundary between bands for radio and microwave electromagnetic spectrum, and have longer wavelengths than optical light. This band of light allows astronomers to probe the dark cores of gas clouds to study the formation of stars and planet, and see a very distant light…

Pillars of Creation 3D Display Shows Evaporation A photograph taken by the Hubble Space telescope is thought to be one of the most amazing space photographs ever captured. The “Pillars of Creation,” [http://en.wikipedia.org/wiki/Pillars_of_Creation] is a picture of interstellar gas and dust in the Eagle Nebula resembling elephant trunks. The pillars are about seven thousand light years from Earth. The picture is of gas and dust in the middle of creating new stars with illumination coming from…

Researches have located a truly colossal black hole at the heart of the recently discovered galaxy known as SAGE0536AGN. The oddly enormous supermassive black hole is approximately thirty times larger than it should be and astronomers cannot seem to figure out why. Researchers from U.K.’s Keele University and the University of Central Lancashire have recently discovered a new black hole that defies all logic. The galaxy, which houses this supermassive black hole, was discovered using NASA’s…
