National Monuments Authority
What's the NEWS

• The full team of National Monuments Authority will visit ancient monuments specially those bordering Tibet-China region of Arunachal Pradesh, between 14th to 18th June, 2022.
• A report will be submitted to Minister of Culture and the Prime Minister, suggesting new additions in the list of Centrally Protected Monuments and identifying cultural tourism sites

Know! about NMA

• National Monuments Authority (NMA) under the Ministry of Culture, Govt. of India has been setup as per provisions of The Ancient Monuments and Archaeological Sites and Remains AMASR (Amendment and Validation) Act, 2010 which was enacted in March, 2010.
• Several functions have been assigned to the NMA for the protection and preservation of monuments and sites through management of the prohibited and regulated area around the centrally protected monuments.
• One amongst these responsibilities of NMA is also to consider grant of permissions to applicants for construction related activity in the prohibited and regulated area.
• A few important changes have been brought in by the 2010 Act. Some of these are:-
• The NMA and the Competent Authorities (CA) were setup and now all applications for construction related work in the prohibited and regulated area are to be submitted to the CA and then to NMA for consideration of the application.
• Statutory provision for the ‘prohibited' and regulated areas.
• Complete ban on construction in the prohibited area.
• Providing statutory procedures for applications seeking permission for construction/repair/renovation.
• Grading and classification of monuments.
• The Act provides for NMA to be constituted with a Chairperson and up to 5 Whole Time and 5 Part Time Members each and a Member Secretary. DG ASI is an ex officio Member.

Binary super massive black hole discovered
What's the NEWS

• An international collaboration of astronomers has discovered a binary super massive black hole in a system which will be a strong candidate for future detection of gravitational waves (GWs).

Know! about Blazers

• Blazars which are super massive black holes (SMBH) feeding on gas in the heart of a very distant galaxy, are among the most luminous and energetic objects in the Universe.
• When the jet, composed of ionized matter traveling at nearly the speed of light, is pointed towards an observer, it is called a blazar.
• The blazar AO 0235+164 is unique as it is gravitationally lensed by intervening galaxies (phenomenon by which light shining from far away to be bent and pulled by the gravity of an object between its source and the observer).
• A group of astronomers from Argentina, Spain, Italy, USA and India has discovered a binary super massive black hole system in the gravitationally lensed blazar AO 0235+164 using extensive optical photometric observations carried out around the globe during last 4 decades (1982 - 2019).
• The blazar AO 0235+164 is the first binary SMBH gravitationally lensed system, which will be a strong candidate of its kind for future detection of gravitational waves (GWs) using the pulsar timing array and future space-based GW detectors.

Know! about Supermassive black hole (SMBH)

• It is the largest type of black hole, with its mass being on the order of millions to billions of times the mass of the Sun
• Black holes are a class of astronomical objects that have undergone gravitational collapse, leaving behind spheroidal regions of space from which nothing can escape, not even light.
• Observational evidence indicates that almost every large galaxy has a supermassive black hole at its center
• For example, the Milky Way has a supermassive black hole in its Galactic Center

Know! about Gravitational waves

• Gravitational waves are ripples in space-time (the fabled "fabric" of the Universe) caused by massive objects moving with extreme accelerations.
• They are disturbances or ripples in the curvature of spacetime, generated by accelerated masses, that propagate as waves outward from their source at the speed of light.
• In outer space that means objects like neutron stars or black holes orbiting around each other at ever increasing rates, or stars that blow themselves up.
• Gravitational waves transport energy as gravitational radiation, a form of radiant energy similar to electromagnetic radiation.

Holy Relics of Lord Buddha to be taken from India to Mongolia

What's the NEWS

• In a special gesture towards people of Mongolia, four Holy Relics of Lord Buddha are being taken from India to Mongolia for an 11-day exposition as part of celebrations of Mongolian Buddh Purnima falling on 14th June, 2022.

Know! about the Holy Relics

• The Holy Relics will be displayed at the Batsagaan Temple within the premises of Gandan Monastery.
• The Holy Buddha Relics, currently housed in the National Museum, are known as the ‘Kapilvastu Relics' since they are from a site in Bihar first discovered in 1898 which is believed to be the ancient city of Kapilvastu.
• The Lord Buddha Relics available in Mongolia would also be displayed along with the relics from India.
• The last time these relics were taken out of the country was in 2012 when their exposition was held in Sri Lanka and were on display at several locations across the island nation.
• India - Mongolia - other highlights
• India has been supporting Mongolia in various fields and in cultural realms.
• India has printed 75 copies of 108 volumes of Mongolian Kanjur and handed over to Mongolian Government and various Buddhist Institutions there.
• The work of digitisation of the Kanjur manuscripts is also in full swing.
• Around 500 Mongolian monks are studying in different monasteries and institutions in India for which India has facilitated their travel and Visas in past few years.

 

Personalities in NEWS
Sri Alluri Sitarama Raju

What's the NEWS

• 125th birth anniversary of the revolutionary freedom fighter, Sri Alluri Sitarama Raju.
• The National Implementation Committee (NIC) under the leadership of the Hon'ble Minister of Home Affairs has approved the commemoration of this event in a manner that is befitting the contributions of the great freedom fighter.

Alluri Sitarama Raju

• Sri Alluri Sitarama Raju is an Indian revolutionary actively involved in the Indian Freedom Struggle.
• Born 4th July 1897, he is revered across the states of Andhra Pradesh, Telangana, Odisha and Karnataka as "Manyam Veerudu" or the "Hero of Jungle" and is a household name in these states.
• Along with the 125th birth anniversary, the Government of India will also be commemorating the 100th year of the popular Rampa freedom struggle which was also led by Sitarama Raju from August 1922 to May 1924 and compelled the British to spend a large amount of resources to defeat the rebellion.

FAST RADIO BURST (FRB)

 

What's the NEWS

• In a paper published in Nature, astronomers have reported a fast radio burst (FRB) whose characteristics are different from almost all other FRBs previously detected, except one.

Know! about FRBs

• FRBs are bright flashes of light that appear for a few milliseconds and then vanish.
• Since the first FRB was discovered in 2007, 140 more were discovered until June 2021, according to a post on the MIT website.
• Their origins are unknown, and their appearance is unpredictable.
• The new study in Nature describes FRB 20190520B, first discovered in 2019.
• What makes it different is that unlike many other FRBs, it emits frequent, repeating bursts of radio waves. And between bursts, it constantly emits weaker radio waves.
• Only one FRB has been previously observed to behave this way. Called FRB 121102, that was discovered in 2012.
