There is no expectation that students have studied galaxies prior to completing this research project. In fact, it is intentionally the first lab, so that most students will NOT know about galaxies yet, because what you may or may not know about galaxies is not important here.
The point of this lab is to learn to look only at the data in front of you. Most of these objects are galaxies far, far from Earth. This is an artifact caused by overexposure, since the telescope had to be focused on this tiny spot in the sky for so long.
You want to identify these objects in order to ignore them for the rest of the lab. They are unimportant for this lab, because they are stars in our own galaxy, and this lab is investigating characteristics of other galaxies.
How many stars can you find? Determine how many galaxies are found in the image. Total number of galaxies in this image?
What is the most common color of galaxy in the image? Precisely explain how you determined this. Are most of the galaxies in this image relatively near or relatively far?
What is your evidence? Note that the picture is about 8 green circles wide and 10 green circles tall, for a total of about 80 green circles over the whole image. Make rough sketches of the five closest galaxies you can find in the image. You have several options for doing this.
You can sketch them on paper and photograph or scan them to upload with your lab or insert into this document. You do NOT need to print the lab document in order to do this.
Sketches on another sheet of paper are fine. Or you can use a computer application to sketch, if you know how to do so. Explain your reasoning and provide specific evidence either from the above tasks or from new evidence you yourself generate using the SkyWalker Web Site. The Hubble Ultra Deep Field is one of most important images in astronomy because it shows some of the most distant galaxies in the Universe.
Explain your reasoning and provide the specific evidence you are using, with sketches or pie charts or graphs if necessary, to support your reasoning.NASA's Hubble Space Telescope snapped this shot of Mars on Aug.
26, , when the Red Planet was million miles from Earth. The picture was taken just 11 hours before Mars made its closest. Big Idea: The Hubble Space Telescope image “Hubble Ultra Deep Field” shows a variety of objects in the very distant Universe that can be systematically and scientifically counted, organized, and classified.
Michael Bolte, the associate director of TMT, thinks the telescope has the chance to change astronomy forever — the same way that Hubble and the Keck telescopes revolutionized the field.. TMT's. The observable universe is a spherical region of the Universe comprising all matter that can be observed from Earth at the present time, because electromagnetic radiation from these objects has had time to reach Earth since the beginning of the cosmological alphabetnyc.com are at least 2 trillion galaxies in the observable universe.
Assuming the Universe is isotropic, the distance to the edge. We help humanity explore the universe with advanced space telescopes and ever-growing data archives. Time, space, and a telescope: Hubble’s most magnificent images With investigations into everything from black holes to exoplanets, the Hubble Telescope has changed not only the face of astronomy, but also our very sense of being in the universe.
On the 25th anniversary of its launch into low-earth orbit, TASCHEN celebrates its most breathtaking deep space images both as scientific feats and.
