Closest Intermediate-Mass Black Hole To Earth

Closest Intermediate-Mass Black Hole To Earth The study of black holes has always fascinated astronomers, especially when it comes to intermediate-mass black holes (IMBHs), which lie between stellar mass and supermassive black holes. Recent research has provided compelling evidence for the existence of an IMBH in the globular cluster Omega Centauri, the most massive cluster

Radio telescopes explained by Mayukh Bagchi

What is a Radio Telescope and How Do They Work?

Radio telescopes are sophisticated instruments that allow astronomers to explore the universe in the radio spectrum. Unlike optical telescopes that collect visible light, radio telescopes capture radio waves emitted by celestial objects. This capability is crucial for studying astronomical phenomena that are invisible in the optical range, such as pulsars, quasars, and cosmic microwave background
