Of Light and Glass (Blog #2)
Humans had been studying the stars for thousands of years before the first telescopes had been invented. The naked eye was enough to understand basic astronomical phenomena in the solar system, but if we wanted understand more, the human eye would need some help. Although they were primitive and only had magnifications of around three … Continue reading Of Light and Glass (Blog #2) → Continue reading

X-Ray Burst Baffles Scientists
In 2014, NASA’s Chandra X-ray Observatory spotted a large, sudden flash, producing the deepest x-ray image ever. Today, this flash still baffles scientists who are attempting to understand its origin. It was given the name CDF-S XT1 and was spotted in an area of the sky known as the Chandra Deep Field South. When the […]

Fun Facts about Telescopes
FUN FACT 1: Galileo is often created as the inventor of the telescope when in fact he was simply the first to use it to study the night sky. The first known practical telescopes were invented in the Netherlands at the beginning of the 1600s, by using glass lenses. They found use in both terrestrial […] Continue reading

Color in the Universe
The pale blue dot is Earth, but what if Earth is the only planet that gives off that specific color? While other exoplanets can and have mimicked the pale blue color, a broader portion of Earth’s overall spectrum shows a rather subtle signature that can only be attributed to life. Earth’s blue color comes from the…

What’s in a Name?
The Hubble telescopes famous successor was not always called the James Webb Space Telescope (JWST). The telescope, initially dubbed the Next Generation Space Telescope, was rechristened in 2002 to pay homage to the celebrated James Webb, NASA’s second administrator. Webb ran NASA from 1961-1968, a time when the emergent agency was still trying to define […]

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…
