  • The U.S. is about to cut its contribution to NATO’s operating budget and Germany is increasing its Payments.
  • North Atlantic Treaty Organization (NATO) is a military alliance established by the North Atlantic Treaty (also called the Washington Treaty) of April 4, 1949, by the United States, Canada, and several Western European nations to provide collective security against the Soviet Union.
  • A key provision of the treaty, the so-called Article 5, states that if one member of the alliance is attacked in Europe or North America, it is to be considered an attack on all members. That effectively put Western Europe under the “nuclear umbrella” of the US.
  • NATO has only once invoked Article 5, on September 12, 2001 following the 9/11 attacks on the World Trade Center in the US.

Why in News?
  • Union Minister for Road Transport and Highways has announced National Highway toll plazas all over India will accept toll only through FASTags.
  • The FASTag is a reloadable tag that allows automatic deduction of toll without having to stop for carrying out the cash transaction.
  • The tag uses radio frequency identification (RFID) technology and is fixed on the windscreen of the vehicle once active.
  • Radio-Frequency Identification (RFID) is the use of radio waves to read and capture information stored on a tag attached to an object. A tag can be read from up to several feet away and does not need to be within direct line-of-sight of the reader to be tracked.
  • The tag is valid for five years and comes in seven different colours — violet, orange, yellow, green, pink, blue, black. Each colour is assigned to a particular category of vehicles.
  • To encourage the use of FASTags, the National Highway Authority of India (NHAI) refunds 5% of the total monthly transactions.
  • Indian Highways Management Company Limited (IHMCL) (a company incorporated by National Highways Authority of India) and National Payment Corporation of India (NPCI) are implementing this program.
  • FASTag is presently operational at both, national and state highways.

3.Climate Emergency

Why in News?
  • The European Union’s Parliament has declared a climate emergency, in a symbolic move aimed at increasing pressure on the incoming European Commission to take a stronger stance on climate change.

  • The climate declaration was passed ahead of the upcoming United Nations’ COP25 climate summit.
  • Similar climate emergency declarations have already been made in several EU member states, including Spain, France and the United Kingdom.
  • Outside Europe only Canada, Argentina and Bangladesh have declared a climate emergency.
  • The resolution will have more symbolic effect than practical impact, and is designed to pressure EU governments to adopt a commitment for Reducing Emissions.
Climate Emergency:

4.Assam Govt. to provide Arsenic & Fluoride Free Drinking Water

Why in News?
  • Assam Public Health Minister, stated that, the state government will provide arsenic and fluoride free drinking water by March 2021. He also added that arsenic was found in the ground water in 24 districts, while fluoride found in 13 districts.

Assam and Ground Water Contamination:
  • The draft report of the Assam State Action Plan on Climate Change (2015-2020) states that Assam has been facing “continued warming of atmosphere” and “erratic rainfall” as a result of which there have been erratic flood and drought conditions since 2003.
  • Climatic changes, like erratic rainfall which results in sudden long, dry spells, leads to less runoff water seeping into the ground and rejuvenating the water table.
  • Some districts with high concentration of Fluoride, fall in the rain shadow areas of Assam.
  • When dilution of aquifers is low (because of erratic rainfall), the concentration (of minerals like fluoride) goes up.This results in increase in concentration of minerals like fluoride, that is pumped up by borewells.
  • Excess Fluoride intake can lead to dental fluorosis (stained teeth) and skeletal fluorosis (bent legs), and arsenic intake is known to cause cancer.

5.Loktak Inland Waterways Project

Why in News?
  • Ministry of shipping has approved Loktak Inland waterways project in Manipur. The project will give impetus to the development of inland water transport connectivity in the North-eastern states and will also boost the tourism sector in the region.

Why in News?
  • The Astronomers discovered a huge Black hole LB-1 in our Milky Way Galaxy.

  • It is discovered using China’s LAMOST telescope.
  • It is 15,00 light year away from earth and mass 70 times greater than the sun.
  • According to most of the current models of Steller evolution, Black holes of such mass should not exist in our galaxy.
  • Steller black holes are usually formed in aftermath of supernova explosion, a phenomenon that occurs when extremely large star burn out at the end of their lives.
  • LB-1’s large mass falls into a range known as ‘pair instability gap’ where supernova should not have produced it.
Steller Evolution Model:
  • It is the process by which a star changes over the course of time.
  • Depending on the mass of the star, its lifetime can range from a few million years for the most massive to trillions of years for the least massive, which is considerably longer than the age of the universe.
  • Some stars are in unstable stage in which their dimensions, temperature, and luminosity change cyclically over periods of hours or days.
  • They are called Cepheid variables serve as standard candles for distance.
  • Some stars blow off their outer layers to produce planetary nebulas.
  • The expanding material can be seen glowing in a thin shell as it disperses into the interstellar medium while the remnant core, initially with a surface temperature as high as 100,000 K (180,000 °F), cools to become a white dwarf.
  • The maximum stellar mass that can exist as a white dwarf is about 1.4 solar masses and is known as the Chandrasekhar limit.
  • More-massive stars may end up as either neutron stars or black holes.
Planetary Nebulas
  • It is abbreviated as PN or plural PNe, is a type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives.
White Dwarf:
  • It is also called as degenerate dwarf, is a stellar core remnant composed mostly of electron-degenerate matter. A white dwarf is very dense: its mass is comparable to that of the Sun, while its volume is comparable to that of Earth.
Red Dwarf:
  • It is the smallest and coolest kind of star on the main sequence. Red dwarfs are by far the most common type of star in the Milky Way, at least in the neighbourhood of the Sun, but because of their low luminosity, individual red dwarfs cannot be easily observed.
Cepheid Variable
  • It is a type of star that pulsates radially, varying in both diameter and temperature and producing changes in brightness with a well-defined stable period and amplitude.
