The James Webb Space Telescope and Hubble Space Telescope were both designed by NASA to study the composition and characteristics of our universe. Both of these telescopes have unique characteristics, allowing them to accomplish different objectives. Size & Dimensions of James Webb vs Hubble Space Telescope The James Webb Space Telescope’s (JWST) primary mirror diameter […]
The Chandra X-ray Observatory (CXO) is a space telescope, designed by NASA in the 1990s. Chandra’s mission is to observe x-ray emissions from high-energy regions of the universe, such as the remnants of collapsed stars, galaxy clusters, and black holes. History of The Chandra X-ray Observatory The Chandra X-ray Observatory (CXO), previously called the Advanced […]
Magnification describes the factor in which an image is magnified. As magnification increases, images will appear larger. As magnification decreases, the field of view will broaden and the image will become clearer. How to Calculate Magnification in Telescopes? The magnification of your telescope is determined by the focal and eyepiece lengths. To calculate this, divide […]
Collimation is the process of aligning all components in a telescope to bring light to its best focus. Most manufacturers collimate telescopes before shipping, but they often require recollimation to achieve the best image. When a telescope is out of collimation, celestial objects may appear blurry. What Are the Types of Collimation in Telescopes? There […]
With a telescope you can see planets, stars, galaxies, constellations, meteors and much more. This article is a guide for astronomers and astrophotographers who are enthralled by the limitless space filled with countless stars. It doesn’t require specialized training or extensive sessions. Simply get a telescope with a suitable lens, or a camera, wait until […]
The focal ratio is a metric used to determine a telescope’s brightness, magnification and field of view. This number, often referred to as the ‘f-number’, describes the relationship between focal length and aperture size. How to Calculate Focal Ratios in Telescopes? The focal ratio can be found by dividing the focal length by the diameter […]
Focal length is the distance between the telescope’s primary lens or mirror and the point where the light rays come together in focus. This is typically expressed in millimeters and is used to calculate key metrics such as focal ratio. How does Focal Length in Telescopes Affect Astronomy? Focal lengths determine the magnification and field […]
The History of the Kepler Space Telescope The Kepler Space Telescope was designed by NASA to study exoplanets using the transit method. It was first proposed in 1994 and renamed in 1996, after German astronomer, Johannes Kepler, who is known for his discovery of laws of planetary motion. Kepler was developed by NASA’s Ames Research […]
The Compton Gamma Ray Observatory (CGRO) was a space observatory that studied gamma rays, the most energetic form of electromagnetic radiation. It was launched into space on April 5, 1991, and operated until its deorbit on June 4, 2000. CGRO was a collaboration between NASA and several international partners, and it was the second space […]
NASA’s Spitzer Space Telescope, initially known as the Space Infrared Telescope Facility, was the fourth and final of NASA’s Great Observatories. Launched on August 25, 2002, Spitzer was NASA’s primary infrared light observatory, allowing astronomers to study the universe in critical parts of the electromagnetic spectrum of light. History of the Spitzer Space Telescope NASA […]
