NASA's (National Aeronautics and Space Administration) Cassini spacecraft has made an incredible observation about the extraordinary deep lakes filled with methane in the Saturn's moon, Titan. This new study has been published in the scientific journal Astronomy.Titan, Saturn's largest moon has methane rain that can fill lakes as much as 330 feet deep.Titan has become only planetary body known to have stable liquid on its surface, apart from Earth.

Karnataka's Kaiga Atomic power station created a world record for the longest uninterrupted operation for 962 days on December 10. It had earlier set a record of 941 days. The earlier record of 940 days by Heysham-2 unit 2 was set by the United Kingdom. Generating Station-1 (KGS-1) at Kaiga in Uttara Kannada, Karnataka has now been shut down for maintenance after 962 days of operation. It will be commissioned again after the maintenance activities. Nuclear Power Corporation of India (NPCIL) said that during its continuous operation of 962 days KGS-1 had produced 5 billion units of electricity at a plant load factor of 99.3%. Kaiga has four indigenously developed Pressurised Heavy Water Reactors of 220 MW each fuelled by domestic fuel. Of them, KGS-2 has been operating since the last 661 days.

Scientists have developed a device named WAND which stands for "Wireless artifact-free neuromodulation device" that works like a "Pacemaker for the brain" to monitor the brain's electrical activity and potentially deliver fine-tuned treatments to patients suffering from diseases like epilepsy and Parkinson's. The most important feature of the device is that it is both wireless and autonomous, which means when it learns to recognize the signs of tremor or seizures then it can adjust the stimulation parameters on its own to prevent the unwanted movements. The device has custom integrated circuits to record the full signal from both the subtle brain wave and the strong electrical pulses.

Scientists have discovered the most-distant body ever observed in our solar system, located over 100 times farther than Earth is from the Sun. The new object has been nicknamed Farout. Earlier, 2018 VG18, the object is the first to be observed at a distance of more than 100 astronomical units from the sun. Farout is about 120 AU, or about 11 billion miles, from the sun. One AU is the distance from Earth to the sun or about 93 million miles

Maitrayee Bose, Indian-origin cosmochemist along with Ziliang Jin, a postdoctoral scholar in Arizona State University's School of Earth and Space Exploration, have found water in asteroid Itokawa samples collected by the Japanese space probe Hayabusa. The research paper detailing the analysis of five of the particles from the asteroid samples was published in the journal Science Advances on 8th May 2019. Itokawa is a peanut-shaped S-type asteroid about 1,800 feet long and 700 to 1,000 feet wide. It circles the Sun every 18 months at an average distance of 1.3 times the Earth-Sun distance. The samples were collected from an area on Itokawa known as the Muses Sea, which is smooth and dusty.

Russia has conducted a final test of a nuclear-capable glider that flies at 20 times the speed of sound. The missile was launched from the Dombarovskiy missile base in the southern Ural Mountains and hit its target on a test site in Kamchatka, about 6,000km away. Avangard is designed using new composite materials to withstand temperatures of up to 2,000 degrees Celsius that come from a flight through the atmosphere at hypersonic speeds.
