NASA's 2020 Mars Rover Now Has an Official Name

NASA announced the name of its next Mars rover: Perseverance.
It will be the fifth exploratory vehicle on the Red Planet following in the tire tracks of the similarly augustly titled Sojourner, Spirit, Opportunity, and Curiosity.
The name was announced at an event at Lake Braddock Secondary School in Burke, Virginia, to congratulate Alex Mather, the seventh grade student who picked it.

IIT-M Develops AI-powered Drones to Counter Rogue Drones

Institute of Technology, Madras, claimed to have developed an AI-powered drone to counter rogue drones (unregulated unmanned aerial vehicles) ensuring safety at vital locations.
The AI-powered system would be an assistance to law enforcement agencies, security services, armed forces in order to secure air space over critical civilian and military installations by rogue drones.
The drones can hack into the GPS navigation system of the rogue drones forcing it to change its flight path or make a safe landing.
The current prototype is equipped to detect and track objects visually, precisely land. The next step will be to conduct exhaustive tests on the system for and ensure its reliability to cater wide range of missions.
The system is designed by department of aerospace engineering, final year student Vasu Gupta, project associate Rishabh Vashistha. The team is mentored by Ranjith Mohan.

Chandrayaan-3 Launch in First Half of 2021

Union minister Jitendra Singh said that Chandrayaan-3 will be launched in the first half of 2021, indicating that there could be a slight delay in the launch of India's third mission to the moon.
In a written response to a question in Lok Sabha, Singh said that the revised configuration takes care of the robustness in design, capacity enhancement for mission flexibility and at the same time retains the heritage of Chandrayaan-II, which hard-landed on lunar surface last year, to the extent possible.

ISRO Calls Off GSLV-F10 Launch

The Indian Space Research Organisation (ISRO) decided to postpone GISAT-1 onboard GSLV-F10 launch due to technical reasons.
The rocket GSLV-F10 carrying India's first agile Earth observation satellite was scheduled for launch on March 5.
This would have been GSLV's 14th flight and eighth with indigenous cryo. It would also have been the 76th launch mission from the Satish Dhawan Space Centre at Shriharikota.

Huge Space Snowman is Two Merging Stars

Researchers have discovered a huge snowman-shaped star with an atmospheric composition never seen before.
It is more massive than our Sun but only two-thirds the Earth's diameter.
The object is thought to have resulted from the merger of two so-called white dwarf stars that often explode as powerful supernovas.
As per Dr. Mark Hollands, of Warwick University, the team's discovery could help scientists better understand how this process occurs.
The most exciting aspect of this star is that it must have just about failed to explode as a supernova. There aren't that many white dwarfs this massive.
"There remains much uncertainty about what kind of stellar systems make it to the supernova stage.

Scientists Detect Biggest Explosion Since Big Bang

Scientists have detected evidence for a colossal explosion in space - five times bigger than anything observed before.
The huge release of energy is thought to have emanated from a supermassive black hole some 390 million light years from Earth.
The eruption is said to have left a giant dent in the Ophiuchus galaxy cluster.
Scentists had long thought there was something strange about Ophiuchus galaxy cluster, which is a giant aggregation containing thousands of individual galaxies intermingled with hot gas and dark matter. X-ray telescopes had spied a curious curved edge to it.
The speculation was that this might be the wall of a cavity that had been sculpted in its gas by emissions from a central black hole.

Astronomers at UBC Astronomy Club Discovers 17 New Planets

University of British Columbia astronomy student Michelle Kunimoto has discovered 17 new planets, including a potentially habitable, Earth-sized world, by combing through data gathered by NASA's Kepler mission.
Over its original four-year mission, the Kepler satellite looked for planets, especially those that lie in the "Habitable Zones" of their stars, where liquid water could exist on a rocky planet's surface.
The new findings, published in The Astronomical Journal, include one such particularly rare planet. Officially named KIC-7340288 b, the planet discovered by Kunimoto is just 1 ½ times the size of Earth - small enough to be considered rocky, instead of gaseous like the giant planets of the Solar System - and in the habitable zone of its star.
