Questions & Answers

Q: Why do we need a space telescope for X-ray radiation?

X-rays are blocked by Earth's atmosphere, so launching telescopes like XMM Newton allows us to study high-energy processes in the universe that emit X-rays, which cannot be observed from the ground.

Q: How does XMM Newton compare to Chandra X-ray Observatory?

Both telescopes have similar scattering mirrors and can detect X-rays, but Chandra is more sensitive and competitive for obtaining observation time. They serve slightly different purposes and have different orbits.

Q: Can the spin of a black hole be measured?

While the direct spin of a black hole cannot be measured, its effects can be detected. The spin of a black hole affects its geometry and the signals of X-rays it emits, allowing scientists to infer some information about the spin.

Q: Are there any future X-ray telescopes planned?

Currently, there are no new large X-ray missions planned, but scientists and researchers are constantly working on developing new instruments and technologies to improve sensitivity and resolution for future missions.
