Which among the following best describes Spektr-RG (SRG), recently see...
Astronomers report the discovery of a new pulsar using the Spektr-RG space observatory.
About Spektr-RG (SRG):
- Spektr-Rentgen-Gamma (Spektr-RG, SRG) is a German-Russian high-energy astrophysics space observatory to study the universe in the X-ray range of electromagnetic radiation.
- It was launched in 2019 on a Proton-M rocket from the cosmodrome in Baikonur, Kazakhstan.
- It moves along a so-called halo orbit around the outer Lagrange point (L2) of the Sun-Earth system at a distance of 1.5 million km from the Earth with a period of about 6 months.
- A Lagrange point is a position in space where the gravitational pull of two large masses precisely equals the centripetal force required for a small object to move with them.
- Instruments:
- The primary instrument of the mission is eROSITA, built by the Max Planck Institute for Extraterrestrial Physics (MPE) in Germany.
- It is designed to conduct a seven-year X-ray survey, the first in the medium X-ray band less than 10 keV energies, and the first to map an estimated 100,000 galaxy clusters.
- This survey may detect new clusters of galaxies and active galactic nuclei.
- The second instrument, ART-XC, is a Russian high-energy X-ray telescope capable of detecting supermassive black holes.
- It is intended to replace the Spektr-R, known as the “Russian Hubble”. Spektr-R was launched in 2011 to observe black holes, neutron stars, and magnetic fields, aiding understanding of cosmic expansion.
Hence option c is the correct answer.

Which among the following best describes Spektr-RG (SRG), recently see...
Space Observatory to Study the Universe in the X-ray Range
SRG, also known as Spektr-RG, is a space observatory designed to study the universe in the X-ray range. It is a joint project between the Russian space agency Roscosmos and the German Aerospace Center (DLR).
Key Points:
- SRG was launched in July 2019 with the goal of mapping the entire sky in high-energy X-rays for the first time.
- The observatory is equipped with two X-ray telescopes, eROSITA (Extended Roentgen Survey with an Imaging Telescope Array) and ART-XC (the Russian-German telescope), which will help in surveying the sky in unprecedented detail.
- SRG aims to observe and study a wide range of cosmic phenomena such as black holes, neutron stars, galaxy clusters, and dark matter.
- The data collected by SRG will provide valuable insights into the structure and evolution of the universe, helping scientists better understand the mysteries of the cosmos.
In conclusion, Spektr-RG (SRG) is a significant space observatory that will provide groundbreaking discoveries in the field of astrophysics by studying the universe in the X-ray range.
