SOLAR SYSTEM

Detailed explanation-1: -Gamma ray telescopes collect and measure individual, high energy gamma rays from astrophysical sources. These are absorbed by the atmosphere, requiring that observations are done by high-altitude balloons or space missions. Gamma rays can be generated by supernovae, neutron stars, pulsars and black holes.

Detailed explanation-2: -By analysing the afterglow of the gamma-ray burst in the X-ray light, scientists produced the first ever evidence of the presence of chemical elements which were the unmistakable remnants of a supernova explosion which had occurred just a few days before.

Detailed explanation-3: -Similar to the way an optical telescope increases our eye’s ability to see faint stars, an X-ray telescope can concentrate the light from an X-ray star onto an electronic eye. An imaging detector can view several X-ray emitting objects simultaneously, or can create pictures of regions of diffuse X-ray emission.

Detailed explanation-4: -We can get a glimpse of this elusive light show thanks to the Large Area Telescope (LAT) aboard NASA’s Fermi Gamma-ray Space Telescope, which observes the sky in gamma rays, the highest-energy form of light.

Detailed explanation-5: -The best place to detect most radiation is above the blocking atmosphere, so some telescopes are put in orbit around the Earth. Even visible light is distorted by the atmosphere, so clearer pictures can be got from orbiting telescopes.

Detailed explanation-6: -The Event Horizon Telescope (EHT), which is a virtual observatory consisting of many telescopes across the world, captured the first image of a black hole. Tracking the radiation from high-energy cosmic events, such as supernovas and collisions between neutron stars.

Detailed explanation-7: -Stars/ galaxies emit many different types of electromagnetic waves/radiation they therefore need different types of telescope to detect them.
