30 Doradus Image Tour
30 Doradus Image Tour Image Tour 30 Doradus as a image tour and I chose this tour because it is the largest star forming region found near our own galaxies and I thought that it would be a good topic to learn about while I am typing this, and if you are reading this I am going to bring you on a tour of writing this whole this so sit back and grab some popcorn and get ready to read. 30 doradus contains things such as Newborn star clusters, Older Star Clusters, Supernova remnant, Pillar Chain, Dark Nebulae, Hot Bubble, Hill Region, and a Runway Star. I am going to break this into parts. A Newborn Star Cluster is a bright and dense star cluster called R136, and is one of the largest star cluster near our galaxy. Stars usually live to nearly a billion years and these stars are 1 to 2 million years old. These stars will eventually explode into supernovae. Bright stars emit a energetic ultraviolet radiation that heats up and erodes the gas clouds around the star cluster. Dense dust covers the gas creat very dark pillars hence the name pillar chain because there is more than just one. Resembling a gaseous version of a coral reef, these fragmented and wispy clouds are along the edge of a large of extremely hot gas.This gas has been heated to about over 1 million degrees by the high energy radiation from hot stars or stellar explosions, this could be why it it super hot. Lastly but not least is a runway star that was caught speeding at a velocity of 250,000 miles per hour. This star though is 1 to 2 million years old meaning that it could of got at a velocity that fast from a stellar explosion or it ejected itself from the newborn gas cluster but if it did it would move a lot slower than how it is now showing that it was a stellar explosion. When gas is heated a lot it starts to glow a pinkish-red because of a newborn star heating up the gas making that star to appear like a rose-like color. Stars form in the deepest, darkest, and deepest part of hydrogen dust clouds. These dark clouds are remnants of a gigantic dark nebulae that is going to be formed.There was more but I didnt want to add it because it might exceed the 1 page limit for the assignment. Discoveries Discovering Planets Beyond In this discovery it changed austomeners lives forever and used hubble to do so but many planets have been found also found with telescopes on the surface but hubble changed eyes forever. It was then they asked questions like how do planets form, are there alien atmospheres that we can live on?, and can we hunt for a planet that is close to us. All these questions have been answered and it was all because of hubble. Now people have been begining theories that planets just are formed from stars that collided with asteroids but actually plantes have been formed by asteroids colliding with each other to make much bigger asteroids and eventually making a planet. This is true because hubble has seen it happen and made a completely new planet. Finding planets around other stars is hard. Planets are tiny relative to most other objects in the universe. And they can be a billion times dimmer than the stars they orbit. Because planets in other solar systems are nearly impossible to see directly, astronomers have had to come up with innovative ways to hunt these covert objects. Only in the past couple decades has our technology and techniques been up to the task of finding extrasolar planets. The Hubble Space Telescope has a wide range of astronomical pursuits from studying black holes in distant galaxies to observing members of our solar system. So it isnt able to dedicate a lot of time to the hunt for extrasolar planets. But that doesnt mean Hubble hasnt tried or succeeded. In fact, Hubble has conducted some of the farthest searches of extrasolar planets ever attempted. It has proven that enigmatic objects discovered by other telescopes are planets. And it has made some exoplanet firsts.. Lastly are we alone in space that question is average because still many other planets that we havent seen so that is still an unknown question.
