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 Continue reading

Observing Invisible Light

The invention of the telescope revolutionized the way astronomers observe the universe. They’ve enabled us to view light from around the galaxies that is not visible to the naked eye. These other forms of light can teach us things that visible light cannot – if we can find a way to visualize them. Astronomers today […] Continue reading Continue reading

Hubble Telescope’s 25th Birthday

On April 24th, 2015, Hubble celebrated its 25th anniversary. It celebrated its birthday by taking some amazing images of some giant star clusters. The image above is one of Westerlund 2 which is a giant cluster of stars and dust – a breeding area for new stars. The dust pillars are the main areas where […] Continue reading Continue reading

The James Webb Space Telescope

The James Webb Space Telescope (JWST or Webb) is set to be the official successor to the Hubble Space Telescope, due to launch is 2018. In order to understand how the JWST will be improving on the Hubble, I think it is first important to understand some of the light aspects of space observation. Model […] Continue reading Continue reading

What Comes After Hubble?

The Hubble Space Telescope, in use for about 25 years, will soon have to be retired in the next 5-10 years. Plans for a successor telescope eventually materialized into the James Webb Space Telescope, pictured below as a full scale model in Austin, TX. As big as a tennis court and as tall as a […] Continue reading Continue reading

Hubble Telescope

In April 1990 NASA launched the Hubble Telescope in an orbit around Earth. The telescope has been orbiting Earth for almost 25 years and is monumental in its contribution to science. The information gathered by the telescope has helped astronomers to narrow down the age of the universe down to a few hundred million years, […] Continue reading 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 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 Continue reading
