The Hubble Space Telescope

Until this past September when LIGO heard gravitational waves, our knowledge of the universe has come from visual observations. When Galileo began using his telescope in the early 1600s, our notion of the natural world completely evolved. Today, we have telescopes whose … Continue reading Continue reading

Blog #2 Observation

Much of what has been covered in class so far has been from the perspective of an observer on Earth. We know that light pollution from cities makes it difficult to see starlight with the naked eye. With that in mind, observatories tend to be far away from city limits. Additionally, they tend to be […] Continue reading

Telescopes and Technology

Pictured above is an artists rendition of the James Webb telescope, a feat of modern technology that is to become the successor to the famous Hubble Telescope currently in orbit. While the Hubble was designed to observe relatively close astronomical phenomena, the JWST will be able to see much further. While at first this fact […] Continue reading

30-Meter Telescope-What does that even mean?

When I first heard the term 30-meter telescope I was quite confused. Did this mean that the telescope is 30 meters long? Does this mean that the telescope is powerful? Based on the size of the telescope in the image above it is clear that the telescope is powerful. The 30-meters refers to the length […] Continue reading

Astronomical Satellites

Astronomical Satellites are observatories of some sort that are in orbit around Earth. These observatories vary greatly in specifically what and how they observe, but they all share the same rational for being in space, instead of on Earth. On … Continue reading Continue reading

The Invention of the Telescope

The telescope was most likely invented in 1608 by a German eyeglass maker named Hans Lippershey, although there is some uncertainty. Another eyeglass maker from the Netherlands, named Jacob Metius, filed for a patent soon after Lippershey and a third man, named Sacharias Janssen, later claimed to be the creator.  Despite these claims, Lippershey is […] Continue reading

Hubble Space Telescope

The Hubble Space Telescope was launched in 1990 and is still in service today. Just as Galileo’s first telescope opened the door to a new world beyond what the naked eyes can see, the Hubble Space Telescope broke through heaven’s gates and showed us a world beyond the boundaries of space-time, capturing even images of […] Continue reading

World’s Largest Telescope To Expand Our Horizons

Image and Information Source Currently, the largest telescope in the world is the Gran Telescopio Canarias, which has an aperture size of about 10.4 meters. However, plans to build an even larger telescope were recently approved. This new telescope will be built at the summit of Hawaii’s Mauna Kea volcano, and will cost an alarming […] Continue reading

Size and Expansion of the Universe

I have always thought that the universe is almost unfathomably huge, but until recently I had not spent much time contemplating how humans have determined this. While reading about the topic, I came across information about the Hubble Space Telescope. Not being familiar with astronomy, I did not know much about it or its purpose. […] Continue reading
