Missing supermassive black hole : Abell galaxy


A missing supermassive black hole that has left astronomers baffled

      WHY IN NEWS:

Scientists have been looking for the black hole using NASA’s Chandra X-ray Observatory and Hubble Space Telescope, and have so far found no evidence that it is anywhere to be found.



A supermassive black hole, which is estimated to weigh up to 100 billion times the mass of the Sun, is seemingly missing, leaving astronomers perplexed.


Every large galaxy in the universe has a supermassive black hole at its centre, whose mass is millions or billions of times that of the Sun

  • Scientists have been looking for the black hole using NASA’s Chandra X-ray Observatory and Hubble Space Telescope, and have so far found no evidence that it is anywhere to be found.


  • The black hole is supposed to be located in Abell 2261, an enormous galaxy cluster that is about 2.7 billion light-years away from our planet.
  • One light-year is the distance that a beam of light travels in one Earth year, which is 9 trillion km.
  • At 2.7 billion light-years away, the Abell galaxy is at an overwhelmingly large distance away from us.


  • Every large galaxy in the universe has a supermassive black hole at its centre, whose mass is millions or billions of times that of the Sun.-NASA.

The black hole at the centre of our galaxy– the Milky Way– is called Sagittarius A*, and is 26,000 light-years away from Earth

  • Scientists have been using data gathered in 1999 and 2004 to look for the centre of the Abell galaxy, but have so far been unable to find its black hole.
  • A reason for this that Abell’s black hole has been ejected from the centre of the galaxy.
  • This also may have happened because of the merging of two smaller galaxies to form Abell– a process in which both of their black holes merged to form an even bigger black hole.


  • When two black holes merge, they release what are known as gravitational waves– invisible ripples travelling at the speed of light, which squeeze and stretch anything in their path.

As per the theory of gravitational waves, during such a merger, when the amount of waves generated in one direction is stronger than another, the new big black hole can be sent away from the centre of the galaxy into the opposite direction

  • This is known as a “recoiling” black hole.

      IASbhai WINDUP: 

So far, though, scientists are yet to find definitive evidence for recoiling black holes

  • As of now, only mergers of significantly smaller black holes have been verified.
  • Should the hypothesis by the researchers turn out to be true, it would mean a major breakthrough in astronomy.

Arunachal Pradesh is likely to become India’s prime producer of vanadium.

      WHY IN NEWS:

The Geological Survey of India (GSI) found promising concentrations of vanadium in the palaeo-proterozoic carbonaceous phyllite rocks in the Depo and Tamang areas of Papum Pare district in Arunachal Pradesh.

SYLLABUS COVERED: GS 1 :3 : Geography : Rocks : Chemistry


This was the first report of a primary deposit of vanadium in India, with an average grade of 0.76% V2O5 [vanadium pentoxide].


  • Vanadium is a chemical element with the symbol V and atomic number 23.
  • It is a hard, silvery-grey, malleable transition metal.
  • The elemental metal is rarely found in nature.

It is recovered as a by-product from the slag collected from the processing of vanadiferous magnetite ores (iron ore)

  • Vanadium is a high-value metal used in strengthening steel and titanium.


  • The largest deposits of vanadium of the world are in China, followed by Russia and South Africa.
  • China, which produces 57% of the world’s vanadium, consumed 44% of the metal in 2017.
  • Vanadium occurs naturally in about 65 minerals and in fossil fuel deposits.
  • It is produced in China and Russia from steel smelter slag.

Other countries produce it either from magnetite directly, flue dust of heavy oil, or as a byproduct of uranium mining

  • It is mainly used to produce specialty steel alloys such as high-speed tool steels, and some aluminium alloys.

Current Affairs News Analysis for UPSC | 11th Jan 2021



  • India is a significant consumer of vanadium, but is not a primary producer of the strategic metal.
  • According to data provided by the GSI, India consumed 4% of about 84,000 tonnes of vanadium produced across the globe in 2017.

      IASbhai WINDUP: 

  • Vanadium mineralisation in Arunachal Pradesh is geologically similar to the “stone coal” vanadium deposits of China hosted in carbonaceous shale.
  • This high vanadium content is associated with graphite, with a fixed carbon content of up to 16%.

Covaxin trials : Side-effects, Irregularities


Bhopal Covaxin trial participants allege side-effects, irregularities

      WHY IN NEWS:

Bhopal-based rights group writes to PM and Union health minister, demanding that ongoing Covaxin trial be halted there

SYLLABUS COVERED: GS 3:Health:Diseases


Several participants  claimed they have suffered various ailments since being administered the first dose of the vaccine in December.


  • A huge chunk of the participant group are victims of Bhopal gas tragedy .
  • Since the trial was not ‘unblinded’, it is not known whether the 21-year-old participant got a vaccine or placebo.


The post-mortem report alleged the person died due to poisoning. His family, however, has refuted the claim


  • Man Singh Parihar, a 70-year-old mason, got his first shot on December 21. He complained of breathlessness and loss of appetite later.

Others complained about problems ranging from “headache to back ache, loss of apetitite, vertigo, etc”

      IASbhai WINDUP: 

  • Bharat Biotech denied the allegations. It claimed to have complied with all rules.

2020 was the hottest year despite La Niña


2020 was the hottest year globally despite cooling La Niña

      WHY IN NEWS:

Matches temperature record of 2016 which began with warming weather events.

SYLLABUS COVERED: GS 3: Climate change : Reports


The year 2020 was the joint hottest year on record globally along with 2016, according to European Union’s Copernicus Climate Change Service (C3S).


  •  Last year was the sixth in a series of exceptionally warm years starting in 2015 and 2011-2020 the warmest decade recorded.

The second half of 2020 was dominated by La Niña conditions which have an overall cooling effect

  • It is notable that 2020 matches the 2016 record despite a cooling La Niña, whereas 2016 was a record year that began with a strong warming El Niño event.
  • Alongside the global rise in temperatures, the European continent also witnessed its warmest year on record in 2020.

It was 0.4 degree Celcius warmer than 2019, which was previously the warmest year

  • Carbon dioxide (CO2) concentrations in the atmosphere have continued to rise at a rate of approximately 2.3 parts per million (ppm) a year in 2020, reaching a maximum of 413 ppm in May, 2020.
  • The rate of growth of CO2 was slightly less than that of 2019.


  • While La Niña is there, the north-south wavy pattern of the jet stream is seen as warm cold patterns in the northern hemisphere midlatitudes.
  • When the jet stream dips south, colder Arctic air follows behind it.

And when it swings north, warm subtropical air invades higher latitudes

      IASbhai WINDUP: 

  • Parts of the Arctic and northern Siberia saw some of the largest annual temperature deviations from average in 2020.
  • The temperature swings for individual months were even more drastic as they regularly reached more than 8°C.
  • The wildfires emitted 244 megatonnes of CO2 in 2020 which is a record and is 33 per cent more than the 2019 record.
  • Arctic sea ice extent was also significantly lower in the last six months of 2020, with July and October seeing the lowest sea ice extent on record for the respective months.
