In 1971, Paul Murdin and Louise Webster made a groundbreaking discovery; they were the first to identify a black hole, which had already been detected but not yet classified. Their analysis has led to the identification of many other black holes, and, later in 2019, to their capture as images. But what is a black hole(BH)?

In the late 1960s, extensive technological development occurred in the US and the Soviet Union as they competed and rushed to advance. In the midst of that, while on the lookout for Soviet nuclear testing, US military telescopes captured the most energetic form of light burst in the universe. Now known as "gamma-ray bursts” or GRBs. The process is directly related to black holes. Credit: NASA's Goddard Space Flight Center Conceptual Image Lab What are these bursts? A gamma-r

In 1992, scientists made a groundbreaking discovery. They captured the existence of a planet outside the Solar System, an exoplanet. To determine whether life could exist beyond Earth, research began. Currently, more than 6,000 exoplanets have been documented, most of which are in the Milky Way. Still, astrophysicists are confident there are way more than we can currently see. Exoplanet Proxima Centauri b (closest exoplanet to Earth): artist's conception image copyright and

In 1967, Jocelyn Bell detected the first evidence of what we now consider to be the most dense object known — a neutron star. A star's fate is almost predetermined by its initial size. So, how big is a star to generate a neutron star? How or why does it become so dense?
