1) Water Worlds: Two alien planets about 218 light years away from Earth have found a twin in the ocean worlds of Europa and Enceladus- moons orbiting Jupiter and Saturn.
- The exoplanets, Kepler-138 c and Kepler-138 d, are likely water worlds a feature that scientists have theorised for a long time.
- It is in the habitable zone, meaning it is located in an orbit that receives just the right amount of heat from its star to allow water to exist in a liquid form.
- The volume of the two alien worlds was three times that of Earth and mass twice as big.
- The Kepler- 138 c and d are made up of ingredients lighter than rock (rocky planets like Earth) but heavier than hydrogen or helium (gas-giant planets like Jupiter).
2) Deepfakes: China recently issued new guidelines to companies and platforms using the deep synthesis technology.
- Deepfakes are a compilation of artificial images and audio put together with machine-learning algorithms to spread misinformation and replace a real person’s appearance, voice, or both with similar artificial likenesses or voices.
- It can create people who do not exist and it can fake real people saying and doing things they did not say or do.
3) INS Mormugao: it is the second of the four ‘Visakhapatnam’ class destroyers, project P15B indigenously designed by the Indian Navy’s in-house organization Warship Design Bureau and constructed by Mazagon Dock Shipbuilders Limited (MDL), Mumbai
- INS Mormugao is equipped with Anti-Submarine Warfare capabilities and is equipped to fight under Nuclear, Biological, and Chemical warfare
- The ship’s firepower consists of vertically launched Barak-8 surface-to-air missiles and BrahMos surface-to-surface cruise missiles for long-range engagement of shore- and sea-based targets. It can operate two multi-role helicopters — Sea King or HAL Dhruv.
- Presently, under the P-15B (Visakhapatnam Class), a total of four warships (Visakhapatnam, Mormugao, Imphal, Surat) were planned and Visakhapatnam and Mormugao are already commissioned in the Indian Navy.
4) Odd Radio Circles (ORC): Odd Radio Circle (ORC) is a very large, (Over 50 thousand times the diameter of our very own Milky Way ~ 3 Million Light-years) unexplained astronomical object that, at radio wavelengths, is highly circular and brighter along its edges.
- They were 1st discovered in 2019 using Australian Square KM Array Pathfinder (ASKAP). However, the ORCs have not been found in visible, Infrared and X-ray telescopes.
5) Tal Chhapar Sanctuary: The Tal Chhapar Sanctuary is known as the home of blackbuck and a variety of birds in Rajasthan.
- The sanctuary is flanked by the Great India Desert, Thar and boasts a unique ecosystem and is an important birdwatching destination in India.
- Fauna: Desert fox and desert cat can be spotted in the sanctuary.
