The Telescope of the “Future”
Living up to its futuristic shape, James Webb Space Telescope is indeed a telescope of “future”: NASA has delayed its launch so many times that this telescope seems to only exist in the future. Jokes aside, the JWST carries with itself enormous scientific potential: it is supposed to be 100 times stronger than the HubbleContinue reading “The Telescope of the “Future”” Continue reading

The Daniel K. Inouye Solar Telescope!
From Earth, the Sun appears to be just a glowing yellow orb. However, the Daniel K. Inouye Solar Telescope in Hawaii has captured new images of the Sun that reveal its violent and explosive nature. This massive four-meter telescope has the technological capabilities that are necessary to better understand the Sun’s magnetic field and outer […] Continue reading

WFIRST: The Newest Vanguard of the Mission to Understand Dark Energy
At some point this decade, a new space observatory will be launched into orbit; one unlike any that we have seen before with extraordinary equipment and capabilities. WFIRST, the Wide-Field InfraRed Survey Telescope, could potentially revolutionize what astronomers know about our universe and how it behaves by focusing on three major categories: dark energy, exoplanetContinue reading “WFIRST: The Newest Vanguard of the Mission to Understand Dark Energy” Continue reading

The window of universe — Various types of Telescope
The science of astronomy is about the telescopes. Without them, our naked eyes can only see thousands of stars in the night sky away from city lights. We get to see galaxies, stars, nebulas and other celestial objects that are light years away from us through telescopes. Furthermore, as the technology improved over the last … Continue reading The window of universe — Various types of Telescope → Continue reading

2200 Nanometers
About 1/50th a hair’s width. That’s the size of the error which seriously set back the Hubble telescope. Perkin-Elmer diagnostics was tasked with grinding down the primary mirror, a 7.8 foot wide *almost* flat surface. The mirror’s curvature was determined by a reflective mirror array which bends a laser to precisely trace the surface’s desired … Continue reading 2200 Nanometers → Continue reading
European-Extremely Large Telescope
The European Southern Observatory began construction of the European-Extremely Large Telescope (E-ELT) back in 2014. This telescope is on track to be the world’s largest optical and infrared telescope by the time it is completed in 2024, thus living up to its name. The E-ELT will include a main mirror that is 128 feet in … Continue reading “European-Extremely Large Telescope” Continue reading

James Webb Telescope
The James Webb Space Telescope, or JWST, will be a large telescope that is intended to be the premier observatory of the next decade. The telescope will study every phase in the history of the universe, from right after the Big Bang to the formation of the universe that we know today, and even the … Continue reading James Webb Telescope Continue reading

James Webb Space Telescope
The James Webb Space Telescope (JWST) is the long awaited successor to the Hubble Space Telescope from which we have received numerous wonderful and famous images of far away stars, galaxies, and other celestial bodies. As the successor to the Hubble, there are, of course, some improvements over the Hubble that are being made with […]

Blog #2
For most contemporary scholars, the modern telescope owes its existence to Enlightenment thinkers who crafted the device to enhance their own stargazing endeavors. However, observing the night sky is hardly a practice that has been limited to the past few hundred years. Thus, it seems likely that there may have been telescopic structures created much … Continue reading Blog #2

The Era of Long Refractors
Telescopes focus light down to a point to increase the light gathering capacity of the astronomer’s eye. The optimal shape for such focus is a parabola, either a parabolic mirror, or a refracting lens of parabolic shape. Unfortunately, parabolic lenses do not have the same curvature everywhere the way spherical lenses do, making their construction … Continue reading The Era of Long Refractors →
