Hubble Space Telescope Images the Most Distant Star Ever Observed

Posted on April 8, 2018 by astronomydylan

Last week, a group of astronomers announced in Nature Astronomy that they had discovered the furthest star ever seen: a blue supergiant named Icarus that shone nearly 10 billion years ago, and located more than halfway across the universe. The astronomers were able to do this with the Hubble, and gravitational lensing. Per the lead author of … Continue reading Hubble Space Telescope Images the Most Distant Star Ever Observed → Continue reading →

Andromeda and the Size of the Universe

Posted on January 20, 2018 by yadavdhruv

  In 2015, Hubble was able to take the most detailed image of Andromeda ever taken. The image had a pixel density of 69.536×22,230 pixels. The picture was taken using 7398 exposures. Images like this really put into light how vast the universe is. In the video, they focus in on a shot of the … Continue reading Andromeda and the Size of the Universe → Continue reading →

Hubble

Posted on March 15, 2016 by imanig625

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… Continue reading →

The Hubble Space Telescope

Posted on February 14, 2016 by martisnv

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 →

Observing Invisible Light

Posted on February 9, 2016 by clharrell

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 →

Hubble Telescope’s 25th Birthday

Posted on April 26, 2015 by pgolemanska

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 →

The James Webb Space Telescope

Posted on February 13, 2015 by bryancm1

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 →

What Comes After Hubble?

Posted on February 12, 2015 by robbyks

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 →

Hubble Telescope

Posted on February 11, 2015 by pgolemanska

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 →
