Shooting Stars

chosen the constellation Draco, the dragon, as my favorite constellation. Draco is my favorite constellation because I adore dragons. Draco is the eighth largest constellation, measured at 1083 square degrees, and is nine of its stars have known planets. Draco’s brightest star is Draconis, and its one meteor shower is known as Draconids. The Greek myth of Draco’s creation has to do with the hero Hercules. The dragon Ladon was the guardian of the garden of the Hesperides, who were the daughters of

milliseconds to a few seconds) neutron stars, which are the end products of the evolutionary stages of massive stars after supernova explosions. As the star collapses, the density becomes large, giving rise to a star consisting mainly of neutrons, with $\sim$ 1.4 {\Msun} and a radius of $\sim$ 10 km \citep{Lattimer13}. They have inferred surface magnetic fields of the order of 10$^{11}$ - $10^{13}$ G \citep{Beskin}, and are the most directly-observable remnants of dead stars in the Universe. Pulsar studies

Research done on this cluster of stars shows that it was documented in the second century by a Greek astronomer named Ptolemy. Sagittarius is the fifteenth largest constellation overall, it occupies eight hundred sixty-seven square degrees and contains the most stars with known planets. This cluster of stars is in the center of the Milky Way galaxy. The brightest stars in the constellation come together to form a pattern of stars called the Teapot. The myth behind the stars is what lead me to my ultimate

Stars are one of the foundations of the universe, and one of the large building blocks that allowed for life to happen. Not only to they allow warmth to hit the Earth, and provide climate conditions that allow the human race to thrive, they produce stardust. Stardust is one of the building blocks that help to create life, and can be found through multiple pieces of evidence that suggest a major connection. To complete this research, I’ll utilize data gathered using scientific instruments on stars

“E=mc2” actually meant. The sudden realization had a deep impact on me. Everything was not the same anymore. Irony, because everything had the same beginning; only the string of events that distinguishes the stars to what we see around. I looked at my hand, while having a mental picture of a glazing star; “Stardust”, I thought, “the calcium in my bones which was made after supernova explosions.” I sat on the floor; unable to speak for an hour, and unable to stop the tears of joy and realization from rolling

Throughout the universe, there are dense molecular or dust clouds, known as interstellar clouds, and they are the first stage of a star. These clouds are incredibly large, containing thousands of times the mass of the Sun, and while they start out stable, for them to one day become a star, they must become unstable. Once this happens, they are no longer able to withstand their own gravity and they break into smaller pieces. The trigger for these events are still unknown, but astronomers think

In galaxy J0230 the disk of debris around the black hole in the center spins very, very fast. The black hole has as much mass as 2.2 billion suns The disk debris is mostly made of gas from surrounding nebulae. The gas orbits the supermassive black hole at around a fifth of light speed. That is around 125 million miles per hour or 200kph. The disk of gas around the black hole is propelled by the radiation emitted by the disk itself. The disk emits radiation because of the friction and gravity

astronomers classified these galaxies into two main types. Flat, rotating, disc-shaped galaxies and large, oval-shaped galaxies with a swarm of distorted stars. The scientists using the NASA/ESA Hubble and NASA’s Herschel telescopes looked further out into the Universe. They want to observe the early galaxies. According to the scientists, 83 percent of all stars formed since the Bing Bang were actually located in disc-shaped galaxies. But they have also explained that today only

us understand the formation of oval galaxies, specifically, the new data answered some old questions about why oval galaxies take so long to form. It turns out that the way a black hole controls the proto-matter of a baby galaxy actually regulates star birth as the galaxy takes shape around it. The Observation of Black Holes When this news came to light yesterday, little did everyone know that the news was already available for scientists to peruse in two journals released in June: The Astrophysical

151). The luminosity of a star is related to its absolute magnitude, and its spectral class has a relation to the star's temperature. So, in order to estimate the size of Betelgeuse, we would need both its luminosity (in which we can substitute its absolute magnitude) and its temperature (spectral class), which we have been provided. The absolute magnitude refers to the brightness of a star "if it were 10 pc away" (Seeds 145), and the lower the number the brighter the star (and vice versa). According
