Recently, a mysterious planet Nine was hypothesized to linger about in the outskirts of our solar system. Even with our most sophisticated equipment, we had largely been oblivious to its presence. But, deep theoretical evidence based upon the gravitational perturbations caused in the outer regions of the solar system that confirm predictions and account for […]Read more "Planet Nine and the Obliquity of the Solar System"
Arthur C. Clarke’s science fiction masterpiece Rendezvous with Rama opens up with the words: “Sooner or later, it was bound to happen. …In those days, there was nothing that men could do to protect themselves against the last random shots in the cosmic bombardment that had once scarred the face of the Moon. The meteorites […]Read more "The Threat of Asteroids"
Mark your calendars! An astronomical phenomenon of great significance will occur this Monday on May 9th. Mercury will cross the sun for the first time since 2006. The transit of Mercury occurs when Mercury passes between the sun and the Earth (inferior conjunction), since of course Mercury is closer to the sun than we are. […]Read more "Transit of Mercury On May 9th"
It is that time of year again where those “once in a lifetime” kind of astronomy hoaxes begin circulating on social media and wow an uninformed crowd. Here’s a hoax which I came across today purporting that Saturn will appear closer to Earth than the moon to offer an spectacular sight. Anyone with a basic understanding […]Read more "Yet Another Facebook Hoax"
“What a delightful irony it will be if the real age of sail has yet to dawn – not only on the oceans of Earth, but also in the far wider seas of space” This is how Arthur C. Clarke envisioned the future of interstellar exploration in the great anthology of essays, poems, and essays […]Read more "A Sail Through the Cosmos"
The mere happenstance of a coincidental sequence of events, put together by the blind works of nature, has serendipitously manifested itself in this fascinating complexity around us today, that only appears to bear the illusion of an orderly calibration of deliberate design. This happenstance of undirected natural processes has led to self-directed sentient beings, pondering […]Read more "The Happenstance of Existence"
Rogue planets wander about in interstellar space, detached from their stars and dislodged from their orbits to float freely into the desolate void of the cosmos! A mechanism which presents a very intriguing phenomenon for astronomers. Although such planets are quite elusively hard to detect owing to their relatively faint nature, a number have been discovered. […]Read more "The Wandering Planet"
