Geology is one of the underrated optional subjects one can choose for UPSC-CSE exam. Since the syllabus is limited and from the science stream it is a high marks scoring potential. Geology is also helpful for students appearing for Indian Forest Service Exam (IFS) exam. […]
100 million years ago, Greenland was on the move. On its tectonic plate, it traveled from a more southern location northward to its current Arctic position, and along the way passed over a mantle plume or hotspot that left a record of its journey in […]
Snow has taken on a sinister-looking blood red colour at a Ukrainian research station due to a type of algae which contributes to climate change. For several weeks, scientists working at the Vernadsky Research Base in Antarctica have been surrounded by what they call “raspberry snow”. Images released by Ukraine’s Ministry of […]
The two largest quakes detected by NASA’s InSight appear to have originated in a region of Mars called Cerberus Fossae. Scientists previously spotted signs of tectonic activity here, including landslides. This image was taken by the HiRISE camera on NASA’s Mars Reconnaisance Orbiter
Certain parts of Earth’s oceans are so oxygen depleted that they can hardly sustain life. Climate models predict that these “dead zones” will expand as global warming progresses, affecting ecosystems, fisheries, and the climate itself. Now Lengger et al. provide new evidence that such predictions do not […]
The divide between lush forest and desert is striking in this photograph taken by an astronaut onboard the International Space Station (ISS). Meandering rivers and farmland comprise most of the lower right half of the photo, while the upper left shows part of the Atacama […]
Deep below the Earth’s surface lies a thick rocky layer called the mantle, which makes up the majority of our planet’s volume. While Earth’s mantle is too deep for humans to observe directly, certain meteorites can provide clues to this unreachable layer. In a study […]
1. Geo Centric Phase The spacecraft is injected into an Elliptic Parking Orbit by the launcher. With six main engine burns, the spacecraft is gradually maneuvered into a departure hyperbolic trajectory with which it escapes from the Earth’s Sphere of Influence (SOI) with Earth’s orbital […]
One of the most luminous stellar explosions ever detected may now be explained. It came from the detonation of a dead star within the dense shell of matter ejected from that sun’s companion star, a new study suggests. Supernovas are explosions that can happen when stars […]
