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 […]

ALMA: First Discovery of a Dust Disc around an Exoplanet

The presence of a dust disc around a Jupiter-like planet outside our Solar System has been caught unequivocally for the first time in astronomical history using the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner. The ALMA telescope has paved the way for the research team led by […]
