Science ka Adda Episode 1: Pluto – A New World

Is there life elsewhere in the universe? How did our Solar System form? Are there black holes at the centre of galaxies? How long do stars live? These are just some of the questions that ‘Science ka Adda’ (Cafe Scientifique) and its host, yours truly, seeks to address. Pluto was discovered in 1930. Up until 2015, we did not know much about this little planet in our Solar System. The flyby of The New Horizon spacecraft has revealed Pluto to be a fascinating object hosting tall mountains made of ice, smooth plains with nitrogen ice flows, and a big moon Charon that appears six times deeper ...

Astronomers now know that a planet – only a little bigger than the Earth – is causing the dimming, as it blocks some of the light heading our way. It is orbiting a sun-like star and is the closest analogue to Earth discovered yet. This way of detecting planets is called ‘Transit Method’ and has turned out to be one of the most successful ways of identifying other worlds. So far, astronomers have detected 5,583 planetary candidates around stars other than our Sun, with 1,879 already ...

We are making history today with our closest approach to Pluto

If you are out and about this afternoon or either sitting at home reading this article, at 4:49pm (PST), look up at the sky (please don’t look straight towards the sun) and wait to be blown away by our advancement in technology. At this precise moment, a machine built by humans will be making its closest approach to Pluto – at the frontiers of our Solar System. This spacecraft, called ‘New Horizons’ has been traveling at the incredible speed of 50,000 kilometres per hour. In case you’re still not impressed, check your speedometer when you are driving on a highway and ...
