NASA Scientists Detect Huge Thermonuclear Blast Deep in Space

NASA recently detected a massive thermonuclear explosion coming from outer space.
The culprit seems to be a distant pulsar, the space agency reports, which is the stellar remains of a star that blew up in a supernova but was too small to form a black hole. NASA spotted the burst because it sent out an intense beam of x-rays that got picked up by the agency's orbital observatory NICER.
All in all, it serves as a potent reminder: space is an extremely dangerous, extremely metal place.
Astronomers think the thermonuclear explosion was caused by helium that sunk beneath the surface of the pulsar and fused into a ball of carbon.

SpaceX Sends Up 60 Mini-Satellites With Plans For Thousands More

The private SpaceX company launched a second set of mini-satellites as it builds a huge constellation of the small orbiting devices aimed at greatly expanding internet access around the globe.
A Falcon-9 rocket launched from Cape Canaveral, Florida, placed 60 mini-satellites in orbit, joining 60 others launched.
The American company's Starlink network could one day total 42,000 satellites -- resulting in far more crowded skies and raising concerns among some scientists.

Online Tools to Gauge post-Ayodhya Mood

Intelligence agencies are using technology called "sentiment analysis programme" to monitor the world wide web and social media platforms for any online propaganda and radicalisation attempts related to the Ayodhya verdict.
The programme is helping police scan for provocative messages and keep tabs on impressionable youths through their online behaviour. By tapping into open source platforms, this programme filters comments and posts on sites and chat rooms to identify hate messages and users.
This tool can study unfiltered information on what people are really saying about a topic and, in the process, manage threats. For example, it generates an alert if somebody writes words like Ayodhya and revenge in the same post.
Another related tech, lexical analysis, is being used to identify frequently searched terms on social media or keywords common within a timeframe. This also helps police interpret information about the accountholder through publicly available data on the internet. Lexical helps police monitor social media and identify threats during sensitive events.
A separate unit named Counter Intelligence Cell (CIC) was created early this year to snoop on open source platforms.
