Taking a Look at Void Galaxies

Stars are the most recognized astronomical object in space and they represent the building blocks of galaxies. Stars distribute elements such as: carbon, nitrogen, and oxygen. A star develops from a cloud of hydrogen and helium, the dust clouds that are scattered throughout galaxies. An example of a dust cloud is the Orion Nebula. The gas and dust begin to collapse from its own gravitational pull. As the cloud collapses, the middle gets hotter. This is known as a prostar. A dense and hot core forms which begins to collect dust and gas. All this material may not end up as a part of the star but can become planets, asteroids, comets, or remain dust. A star about the size of our sun can up to 50 million years to mature. The smallest stars are

The moons, asteroids and comets are smaller surrounding bodies. The Galaxy is an enormous cloud consisting of stars, gas, and dust. An accumulated gravity of its matter holds the Galaxy together. The Universe is made up of everything that exists. This includes galaxies, stars, and planets.

It's about four million times the mass of the Sun. It's surrounded by a cluster of young stars, some of which plunge to within a few billion miles of the black hole. And although it's quiet today, a century ago it gorged on a clump of matter that passed too close, creating a pyrotechnic display that lit up the Milky Way's heart. Much of that evidence has been amassed by two teams, one led by Ghez and another by Reinhard Genzel, director of the Max Planck Institute for Extraterrestrial Physics in Germany. Using giant telescopes in Hawaii and Chile and cutting-edge observational techniques, they have probed closer to the black hole than ever before. That has allowed them to plot the orbits of giant stars that pass hair-raisingly close to the black hole, providing the best measurement of the black hole's mass. And it has revealed that some of the stars around the black hole are far younger than expected. "There's been a myriad of surprises, which is the fun of doing research," says Ghez. "You go in expecting to answer one thing and you come out the other end with more questions than you started with." The central question that Ghez, Genzel, and others hoped to answer was whether a supermassive black hole inhabits the center of the Milky Way. As early as 1980, radio observations revealed that gas was swirling around a dark, massive object at the center of the galaxy. That object, which glowed steadily at radio

Stargazing is often thought to be something lovers would do on a date or something of a hobby. Astronomers and scientists of all kinds make their careers out of it every day.

Halos are the gaseous atmospheres of galaxies. The properties of these gaseous halos control the rate at which stars form in galaxies according to models of galaxy formation, explained the lead Nicolas Lehner. The gargantuan halo is estimated to contain half the mass of the stars in the Andromeda galaxy itself, in the form of a hot, diffuse gas. If it could be viewed with the naked eye, the halo would be 100 times the diameter of the full Moon in the sky. This is equivalent to the patch of sky covered by two basketballs held at arm's length.

Astronomers in a new study have observed around 10,000 galaxies. Which are currently present in the Universe using a survey of the sky. Survey is created by the Herschel ATLAS and GAMA projects.

The Milky Way is a barred spiral galaxy with a diameter between 100,000 and 180,000 lightyears.

Active Galactic Nuclei (AGNs) are very luminous and dense regions in the center of galaxies believed to host Super Massive Black Holes (SMBHs). The electromagnetic radiation sent out from AGNs is conjectured to come from matter that the SMBHs accrete which then takes the form of an accretion disk circling the black hole. These accretion disks are best approximated with an irregular density and temperature distribution made up by very hot gas and plasma~\citep{skadowski2015global}.

Mercury doesn’t have an atmosphere, so it can’t contain the heat from the sun. Temperatures on the planet can reach 800 degrees fahrenheit (pretty darn hot!) and can reach 290 degrees below fahrenheit (brrrr!!!). As you

Stellar Black Holes: It is consisted when the middle of a very massive star collapses on itself. This collapse also causes a supernova that explode a part of the star into space. (Mathew,2012)

The galaxy contains more than a trillion galaxies, each with millions of stars and countless amounts of planets. So, the project “Galaxy Zoo” aims to classify some of these distant galaxies within the universe according to their shapes and appearances. Started in 2007, the Sloan Digital Sky Survey contributed around a million images of various galaxies in hopes to gain a better understanding about how galaxies form and what dark matter is. So, this paper will explore interesting findings within the classification process and the project’s educational impact.

Out of all the galaxies, the Milky Way is the place where intelligent life originated. Humans, which have lived on earth for 200,000 thousand years, have thrived in its perfectly balanced ecosystem. Although, many centuries have passed, humans have not been able to explore space thoroughly yet we are mere specks of sand on a beach. Today’s government should be supporting NASA’s search for extraterrestrial life instead of being egocentric.

There are many types and morphologies of galaxies. First, there are elliptical galaxies which have elongated structures, like an ellipse. An elliptical galaxy on the Hubble Sequence, a classification system for galaxies, either range from E0, being nearly spherical, or up to E7, being
