AGN’s or Active Galactic Nuclei are Galaxies that have Active Blackholes. Active Blackholes are those that accrete on the gas and around it. They swallow ionized gas which heats up as it comes nearer to the Blakhhole. Some of the ionized gas is emitted in a direction parallel to the…

Near-Earth Objects known as NEOs always have a certain factor of risk embedded in them for our planet. Also, one of the popular theories for the extinction of dinosaurs is the impact of a huge asteroid, we know what impact a NEO can have if it goes undetected. This led…

Exomoon is a moon orbiting an exoplanet. Just as planets in our solar system have moons orbiting them, exoplanets too can have moons orbiting them. But finding an exoplanet itself is a difficult task, let alone an exomoon. Exomoons represent a critical link for Astronomers to understand exoplanets and their…

Asymptotic Gaint Branch (AGB) is a region In the Hertzsprung — Russel diagram that is populated by evolved cool luminous stars. All-stars lying in this region are known as AGBs and the stage after this is known as post-AGBs. This post-AGB stage is the least understood stage in the evolution…

EP-3 What Could be Dark Matter? In the last episode, we covered some of the candidates which we could safely discard, from being candidates of Dark Matter. Now, we will look at some of the candidates that have a shot at being called possible candidates of Dark Matter. When searching for particle candidates of Dark Matter…

EP-2 What Could Not Be Dark Matter? In the last part, I covered how we got an idea that something like Dark Matter, which is invisible to us, could be established to exist. It is not just a theory, but rather, in this case, it is proven to exist by various observations and the scientific community is…

EP-1 How did we detect Dark Matter? In 1937, a scientist named “Zwicky” published a paper in which he mentioned that there was a “Mass Discrepancy” problem which he found after studying the “Coma Cluster”. This Coma cluster is a cluster of galaxies, and using the motion of some galaxies in the cluster as a tracer of…

Could Exoplanets have such orbits which pitch them perpendicular to each other? Hard to believe….. isn’t it? But when it comes to science anything and everything is possible. Recently, scientists have found one such pair of exoplanets, which according to them are at nearly perpendicular orbits to each other. The…

Proto-planetary disk, as the name suggests is a rotating disk of gas and dust formed around a young star. Studying such disks gives us a piece of information about the formation and early evolution of planets in the respective systems. Some of them have spiral arms in the disks. The…
