The finding makes the world – which is called K2-18b- a plausible candidate in the search for alien life.Within 10years, new space telescopes might be able to determine whether K2-18b’s atmosphere contains gasses that could be produced by living organisms.The lead scientist, Prof Giovanna Tinetti of University College London (UCL),described the discovery as “mind blowing”.”This is the first time that we have detected water on a planet in the habitable zone around a star where the temperature is potentially compatible with the presence of life“.The habitable zone is the region around a star where temperatures are considered sufficiently benign for water to exist in liquid form on the surface of a planet.The new planet is just over twice the size of Earth – in a planet category known as a “super Earth” – and has a temperature cool enough to have liquid water, between zero and 40C.K2-18b is 111 light-years – about 650 million million miles – from Earth, too far to send a probe. So the only option is to wait for the next generation of space telescopes to be launched in the 2020s and to look for gases in the planet’s atmosphere that could only be produced by living organisms.
The 30th of January, is National Cleanliness Day. I didn’t even know we had one! We have two, for the record, the other being on 2nd October.This day is also observed as Martyr’s Day to mark the assassination of Mahatma Gandhi, the man who started with the whole Swacch Bharat concept in the first place.So we all posted patriotic quotes and shared emotional videos about desh-bhakti a few days back on Republic Day. All that nationalism dies soon after sun down and we go back to our normal lives,cursing the government for everything that is going wrong with our lives, from taxes to traffic to filthy streets.With environmental issues like water contamination, pollution, and climate change, it’s natural to look for ways we can reverse the damage to our planet and keep our environment clean. Many of us think we’re too small to make a difference, but when enough of us take action, we’ve seen the positive results we can create.
Janmastami, Hindu festival celebrating the birth (janma) of the god Krishna on the eighth (ashtami) day of the dark fortnight of the month of Bhadrapada (August–September). The number eight has another significance in the Krishna legend in that he is the eighth child of his mother, Devaki.The occasion is observed especially in Mathura and Vrindavan (Brindaban), the scenes of Krishna’s childhood and early youth. On the preceding day devotees keep a vigil and fast until midnight, the traditional hour of his birth.Then the image of Krishna is bathed in water and milk, dressed in new clothes, and worshipped. Temples and household shrines are decorated with leaves and flowers; sweetmeats are first offered to the god and then distributed as Prasada (the god’s leftovers, which carry his favour) to all the members of the household. The devotees of Krishna commemorate the events of his birth by preparing elaborate representations of Mathura, where he was born, the Yamuna River, over which he was transported to safety, and Gokul (ancient Vraja), the scene of his childhood, using small images of the god, the other participants, and the animals and birds of the forest. Pots of milk are hung from tall poles in the streets, and men form human pyramids to reach and break the pots- this in imitation of Krishna’s childhood play with the cowherd boys, when they stole the curds hung out of reach by their mothers. The festival is also a time for group singing and dancing.
