In 2019, researchers captured the first image of a black hole. They were able to do this by having all the major radio telescopes on Earth act together to simulate a radio telescope that was the size of Earth. Before this, we could only see indirect evidence of the existence of black holes. This particular […] Continue reading

How Astronomy may harm Life on Earth

A new study by Nature Astronomy has tapped an estimate for the greenhouse gas emissions of the astronomy industry. Unfortunately, despite the fact that the global astronomy industry is much smaller than many other industries, its emissions are strikingly large. The number estimated by this study is a staggering 20 million tonnes of CO2 annually. […] Continue reading

The Hubble Telescope and Spectroscopy

When many people think about the Hubble Telescope, they tend to think of some of the most spectacular photos that it has captured over its five missions (with an example displayed in Figure 2). However, some people may fail to recognize the importance of the spectrographs that the Hubble Telescope produced and the valuable information […] Continue reading

The James Webb Space Telescope (Post 2)

The Hubble Space Telescope has been a staple in the NASA space program since its launch in 1990. It has led to monumental discoveries and pictures such as the famous Hubble Deep Field; however, 30 years later, technology has evolved tremendously and so, NASA has launched a new telescope aimed at succeeding it. Planning of […] Continue reading

Galileo and the Telescope

Galileo and the telescope have become synonymous over the ages. It’s difficult to think of one without also considering the other. But it was not Galileo who invented the telescope– although he was one of a few who revolutionized its use for astronomy. The telescope’s origins can be traced back to English philosopher Roger BaconContinue reading “Galileo and the Telescope” Continue reading

Culmination Reflection Post

After taking Astronomy 2110, not only has my perspective of our Solar System changed and widened, but also did my view on the universe as a whole. Perhaps one of the biggest eye-openers for me came near the beginning of the semester when we learned just how vast our Universe is as a whole. BeforeContinue reading “Culmination Reflection Post” Continue reading

A home for future humans?

Size Comparison of Kepler 62e and 62f with Earth With the rate at which we are destroying our planet, we are likely to need a new Earth sometime in the future. Luckily for us, there are two potentially habitable planets that were discovered in the Kepler 62 System, called Kepler 62e and Kepler 62f. TheseContinue reading “A home for future humans?” Continue reading

TESS: The Modern Exoplanet Finder

The Kepler mission marked a significant jump in exoplanet discovery when the space telescope was launched over 10 years ago. Since then, astronomers worked hard to research, develop, and design a more modern approach to discovering these distant and unknown planets. The solution was the Transiting Exoplanet Survey Satellite (TESS). TESS’s mission was to lookContinue reading “TESS: The Modern Exoplanet Finder” Continue reading

History of Telescopes

While there were some objects artificially resembling telescopes in the ancient world, and even some used for sighting, the first modern telescope would have been the work of a Dutch glasses-maker named Hans Lippershey, in 1608. This is merely the first documented one though, as he was the person to file a patent, and theContinue reading “History of Telescopes” Continue reading

The Thirty Meter Telescope

Currently, the largest single-aperture telescope in the world, the Gran Telescopio Canarias, spans 10.4 meters (about 32 feet). This telescope can see 500 million light-years deep into space, which was thought to be impossible out of a single, segmented reflecting telescope until it was built in 2006. While 10.4 meters is large, astronomers worldwide feltContinue reading “The Thirty Meter Telescope” Continue reading
