Bharti-backed OneWeb, ISRO Unit Sign Agreement for Satellite Launches

OneWeb, a company backed by the Bharti Group, and New Space India Limited, the commercial arm of the Indian Space Research Organisation, inked an agreement for satellite launches.
New Space's first launch is anticipated in 2022 from the Satish Dhawan Space Centre (SDSC) in Sriharikota in Andhra Pradesh.
The launches will add to OneWeb's total in-orbit constellation of 428 satellites, which is 66 per cent of the planned total fleet, to build a global network that will deliver high-speed, low-latency connectivity.

Astronomers Find New Type of Star Explosion �" A Micronova

Astronomers detected a previously unknown type of stellar explosion called a micronova involving thermonuclear blasts at the polar regions of a type of burned-out star called a white dwarf after it has siphoned material from a companion star. Micronova is by far the least powerful type of star explosions now known -- less energetic than a blast called a nova in which a white dwarf's entire surface blows up and tiny compared to a supernova that occurs during the death throes of some giant stars.
Micronovae are observed from Earth as bursts of light lasting about 10 hours. They were documented on three white dwarfs - one 1,680 light years away from Earth, one 3,720 light years away and one 4,900 light years away. A light year is the distance light travels in a year, 9.5 trillion km.
The researchers discovered the micronovae when analysing data from NASA's TESS space telescope. They used the European Southern Observatory's Chile-based Very Large Telescope to confirm the explosions involved white dwarfs.

A First, Himachal Begins DNA Database Creation

Himachal Pradesh has become the first state in the country to initiate creation of DNA database that will be of immense help in investigating heinous crimes, identification of disaster victims and unclaimed bodies, missing persons and habitual offenders. The Directorate of Forensics Services, Junga, has procured DNA profile databasing and matching technology (Smallpond TM software from the USA) at a cost of Rs. 55 lakh. It has a capacity of about 20,000 DNA profiles that can be scaled up further.
Local database of DNA profile information can be created and maintained with this facility that enables efficient matching of new DNA profiles with the existing ones in seconds. On average, 600 cases with biological evidence come for DNA profiling in the state every year.
The State Forensic Science Laboratory, Junga, is the first lab to acquire this technology and the facility is on a par with international standards.

Three Chinese Astronauts Return To Earth After Six Months In Space

The two men and one woman -- Zhai Zhigang, Ye Guangfu and Wang Yaping -- returned to Earth shortly before 10 am Beijing time (0200 GMT), after six months aboard the Tianhe core module of China's Tiangong space station.
Three Chinese astronauts returned to Earth after 183 days in space, ending China's longest crewed mission as it continues its quest to become a major space power. The Shenzhou-13 spacecraft was the latest mission in Beijing's drive to rival the United States, after landing a rover on Mars and sending probes to the Moon.
The world's second-largest economy haD poured billions into its military-run space programme, with hopes of having a permanently crewed space station by 2022 and eventually sending humans to the Moon.
