Asteroskopeio: A Stellar Odyssey on Great Observatories
Asteroskopeio, in its voyage to unveil the cosmic wonders of the four Great Observatories launched by NASA between the years 1990 and 2003, has now successfully brought to light the marvelous story of imagery and analysis of the space telescopes while delving into their scientific arts. With the aim of exploring the reigning everlasting triumphs […]
Through the Eye of Hubble: Infinitely Wondrous
On a quest to perform groundbreaking observations, and provide data for numerous more groundbreaking discoveries, the Hubble Space Telescope (HST) set out in the spring of 1990. Over 1,000,000 observations, over 18,000 papers published based on data from the HST, and 6 service missions later; the Hubble still orbits above us, its 3rd decade of […]
Hubble Space Telescope: A Window to the Universe
Hubble Space Telescope (HST) was the first in the family of great observatories to witness the glamour of the universe. It has been orbiting around the Earth at a distance of about 540 km since its launch and deployment by the space shuttle Discovery (STS – 31) on 24th – 25th April 1990. “A telescope […]
Cosmic Epic Unfolding Infrared Wonders: The Spitzer
On a Voyage to Detect Infrared Radiation Launched in 2003, the Spitzer Space Telescope (SST) is the final mission in NASA’s Great Observatories Program – a family of four space-based observatories including Hubble Space Telescope (HST), Compton Gamma-Ray Observatory (CGRO), and the Chandra X-Ray Observatory (CXO), designed to observe the universe in a different kind […]
Voyage to Unveil the Hazy: Spitzer Space Telescope
To unravel the cornucopia of hidden mysteries and to gather information on remote planets, galaxies, and other astronomical entities, NASA initiated the concept of a multi-wavelength set of Great Observatories by giving birth to four legendary observatories; to study the universe at the entire electromagnetic spectrum. Its fourth and last element is the Spitzer Space […]
The Compton Observatory’s Quest: Bursts and Maps
Among the observatories established by NASA, the Compton Gamma Ray Observatory holds a special place because of the unique discoveries it made during its golden age. Compton followed the Hubble into orbit as a great observatory to examine the events corresponding to the high energy light or the Gamma rays. The observations it made significantly […]
Mapping a High-Energy Universe: Compton Gamma Ray Observatory
On a quest to find out the mysteries of the observable universe, we needed to redefine the word “observable”. With the development of the electromagnetic spectrum, we realized that to the human eye only a very small range of light is actually visible. This realization led the way to the need and supply of instruments […]
Our X-Ray Universe: Amazement Captured over 20 Years on Duty
Since its launch on July 23, 1999, the Chandra X-ray Observatory has been NASA’s flagship mission for X-ray astronomy. Specially designed to detect X-ray emissions from extremely hot regions of the universe, it has captured spectacular pictures of several cosmic objects. This catalogue includes supernovae and their remnants, galaxy clusters, planetary nebulas, and matter surrounding […]
Chandra X-ray Observatory: Expedition to Unravel a Marvelous Universe
NASA’s Chandra X-Ray Observatory (CXO) is a telescope specially designed to detect X-ray emission from all sources of high energy in the universe that are invisible to the human eye. This great observatory was formerly known as the Advanced X-Ray Astrophysics Facility (AXAF) and has joined the Hubble Space Telescope (HST) and the now-defunct Compton […]
