Our Origin Story That Started with a Bang
Sahaana Vijay Introduction Before unravelling the mysteries of the Universe, it is important for us to know about our origin and our place in this vast domain. We have been walking on this earth for the past three to seven million years and have evolved drastically. The earliest Homo sapiens dispersed out of Africa around …
An Ingenious Perseverance: The Search for Life on Mars
Abstract: Recently, NASA’s Perseverance rover (equipped with the Ingenuity helicopter) landed on Mars and is investigating the crater Jezero, a place where scientists think they might fight find possible signs of life through the leftover marks of deltas and rivers and the rocks that might contain life-signalling minerals. The Perseverance rover is only a part …

Colourizing The Universe
Introduction It may come as a shock to some of you that all images received from space telescopes are black and white. They are colourized later. But first, let\’s understand how cameras work and if there are any differences between cameras in smartphones and cameras sent to space. How cameras in smartphones work The camera …
Stars and their Colours
Abstract Stars are often described in terms of their colour. Sentences like “Betelguese is a Red Supergiant” and “The Sun is a Yellow Dwarf” paint an image, but there is also a great deal of physics behind them. Stars emit light in a way similar to black bodies. The wavelength of electromagnetic radiation that a …
A brief overview about how the Laser Interferometer Gravitational-wave Observatory works
By Chinmay Pala Abstract In this paper, the author explains how the Laser Interferometric Gravitational-wave Observatory (LIGO) detects gravitational waves and goes over the differences between initial LIGO and advanced LIGO. Beginning by explaining the formation of gravitational waves, the author then gives an overview of the history and locations of LIGO. In the main …

Design for a Europa Subsurface Explorer Mission with a Telescopic Subsurface Vehicle
Abstract Europa, one of Jupiter’s four large Galilean moons, is a target of prime importance for exploration. This is due to the likely presence of a global subsurface liquid water ocean beneath a water ice crust, raising the possibility that Europa could support simple life. Future mission concepts include a lander deploying a probe to …
