Twin Galaxies

many questions an average person would ask such as, How was the universe formed, how old is the universe, and will the universe expand forever? The universe is a huge wide open space that holds everything from the smallest particle to the biggest galaxy. Isn't that crazy? For the question many that many were asking, scientifically, about 13.7 billion years ago, a powerful explosion happened called…

NGC 584 is an elliptical galaxy in the constellation Cetus. The galaxy was discovered on 10 September 1785 by the German-British astronomer William Herschel. Number 20 in the Herschel 400 list is NGC 584. NGC 584 is a moderately large and bright elliptical galaxy in Cetus. In an 18 inch telescope it appears as an elongated patch of light with a bright center. The two bright galaxies either side of NGC 584 are the 13.2 magnitude NGC 582; (left) and the 15.2 magnitude PGC 1028168. (Right). While…

H-R Diagram Lab-Plotting the Stars Part I: Introduction 1) One method scientists use to measure the distance of the star is called parallax. Parallax shift is when closer stars shift positions against the farthest stars. In order for astronomers to measure that distance, they measure the distance of the shift, also considering the diameter of the Erath’s orbit. Then the angle of the parallax is measured. The smaller the angle of the parallax shift is, the farther away the star is from the…

To me, astronomy is the study of the universe and everything in it. This includes the planets, moons, stars, comets, etc. The major difference found between Muggle astronomy and Wizarding astronomy is that the Muggle world has "laws" that explain what they see in the universe. The study of these laws of the universe in the Muggle world is called "physics". Although these laws do explain a vast majority of what the Muggles see on Earth and in the universe, it may not hold true in the Wizarding…

as NGC 3031 or Bode's Galaxy) is a spiral galaxy about 12 million light-years away in the constellation Ursa Major. Due to its proximity to Earth large size and active galactic nucleus] or supermassive black hole), Messier 81 has been studied extensively by professional astronomers. The galaxy's large size and relatively high brightness also make it a popular target for amateur astronomer. Messier 81 was first discovered by Johann Elert Bode in 1774.Consequently, the galaxy is sometimes referred…

The messier galaxy is galaxy that is seventeen million light years away. This galaxy can be seen in the constellation Hydra. This galaxy is a spiral pinwheel galaxy and is also one of the brightest galaxies in the sky. The galaxy messier 83 was founded in February 23 in 1752 by Nicolas Louis de Lacaille. Lacaille found the Messier 83 galaxy off of the Cape of Good Hope. In March of 1781 Charles Messier added this galaxy to his catalog of nebulas objects, known as the messier catalog. Later on…

universe barren or teeming with life? The observable universe; the part of the universe from where the light has had time to travel to earth is approximately 90 billion light years in diameter. There are 20 billion sun-like stars in just our Milky Way galaxy and recently we learned that planets are much more common than we thought. Those are the planets which are situated within the goldilocks zone of its home star, where the temperature is just right for water to remain in liquid state and…

process in the universe able to produce this much energy (Bhat, 2011). Additionally, if a GRB was able to distribute itself in all directions equally, such as the way a star does, its luminosity would be that of the combined brightness of a million galaxies such as our Milky Way, albeit briefly (Bennett et al.,…

Many Mizzou students are surprised to hear that the campus is home to an observatory. In fact, the observatory has been serving Mizzou students for over 100 years. The observatory is named after university president Samuel Laws, who personally donated $2,000 to help finance the new observatory for the university. The observatory has had multiple locations on campus before reaching its current spot on top of the Physics Building shortly after its 1964 construction. Galileo Galilei is widely…

Hubble space telescopes have discovered a massive galaxy creating more and more new stars. The way that this massive cluster has been formed so quickly is by feeding off gases from other galaxies. Tracy Webb of McGill University explained that usually a star in the center of a galaxy is old and dead, but this new cluster within this rare galaxy is creating new stars very quickly by merging with other smaller galaxies. Clusters are families of galaxies bound together by the ties of gravity.…
