Avi Loeb is not exactly someone whom one may call an outsider to the scientific community. As a reputed scholar and the longest serving chair of Harvard’s Department of Astronomy, he is a well-known and reputed physicist with many years of experience in astrophysics and cosmology. It is therefore somewhat surprising that in this book … Continue reading Is ʻOumuamua an Alien Artifact: Exploring Avi Loeb’s Controversial Theory
Pip: Divyanshspacetech covers a lot of sky — and apparently some of the ground beneath it too. Mara: That's right. This episode moves from reusable rockets and the cryogenic systems powering them, through some genuinely strange physics and planetary science, to questions about life in the universe and a few surprising stories closer to home. … Continue reading Podcast Episode: Space Science And Cosmic Mysteries
The fluid, which defies everyday laws of motion, is a rare achievement and provides a platform to study an otherwise hypothetical form of matter. Scientists have created a fluid that exhibits the bizarre property of “negative mass” in an experiment that appears to defy the everyday laws of motion. Push an object, and Newton’s laws … Continue reading Scientists Create Fluid with Bizarre Negative Mass Properties
Most large galaxies are thought to harbour supermassive black holes in their central regions. These enormous gravitational powerhouses can weigh anything from a few hundred thousand to several billion times the mass of a normal star. In some galaxies, such as our own Milky Way, these black holes may be dormant. But in active galaxies … Continue reading 🌌 Is the Milky Way’s Supermassive Black Hole Shaping the Universe’s Most Powerful Cosmic Rays? 🕳️⚡
Ever since Voyager 2 beamed home spectacular images of the planets in the 1980s, planet-lovers have been hooked on auroras on other planets. Auroras are caused by streams of charged particles like electrons that come from various origins such as solar winds, the planetary ionosphere, and moon volcanism. They become caught in powerful magnetic fields … Continue reading Cosmic Light Show: Hubble Reveals Spectacular Auroras Dancing on Uranus
The largest haul of confirmed planets obtained since the space observatory transitioned to a different mode of observing includes a planetary system comprising four promising planets that could be rocky. An international team of astronomers led by the University of Arizona has discovered and confirmed a treasure trove of new worlds using NASA’s Kepler spacecraft … Continue reading K2 Mission Confirms Rocky Planets in Newly Found System
The story of Earth’s origin is one of the most fascinating narratives in planetary science, a journey that spans billions of years and begins in the depths of space. Understanding how Earth formed not only reveals the origins of our planet but also provides insight into the processes that shape planetary systems across the universe. … Continue reading The Formation of Earth: From Cosmic Dust to a Living Planet
The cosmos is a repository of a great many mind-blowing notions, be it dark energy, dark matter, the notion of infinity, the billions of galaxies each with billions of stars, the Big Bang narrative, and the breathtaking spaceship journeys. But the cosmos is also a source of great gifts and surprises. The last comes from … Continue reading Are We Alone in the Universe: The Search for Human Life Beyond Earth
