Galileo’s Telescope
Most people credit Italian astronomer Galileo Galilei (1564-1642) with building the first telescope. He did not, but he made great improvements and ingenious use of the instrument. Before the telescope were lenses. In the 13th century, Italian artisans created lenses for glasses to be worn by scholars with failing eyesight. The process of making glass was difficult, as unrefined … Continue reading Galileo’s Telescope

The Hubble Telescopes
(Photo by NASA) Since it first introduction, telescopes have served mankind a vast deals of researches experiences and discoveries of planets, moons and other intergalactic contents. As we all know telescopes help us to see stars beyond our naked eyes. It becomes a defense mechanism to predict the fall of asteroids or predict movements of celestial […]

Hubble
The Hubble telescope, which has been orbiting Earth for over 25 years, views the universe with a completely different perspective than what we can see on Earth. While the telescope is not necessarily responsible for amazing images like this one, it can be given credit for other just as powerful views of the universe. Its…

MUSE Telescope
The Multi Unit Spectroscopic Explorer (MUSE) telescope is one of the newest telescopes that allows us to get 3D views of the universe. MUSE is installed on the European Southern Obserbatory’s Very Large Telescope in Chile. It took over a decade to design and develop it but finally went online in March of 2014 and captured… More MUSE Telescope

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 →

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 […]

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 […]

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 […]
