  • James Webb Space Telescope

    NASA has unveiled images from the James Webb Space Telescope, the largest and most powerful orbital observatory ever launched.

    What is the image about?

    • NASA released a deep field photo of a distant galaxy cluster, SMACS 0723, revealing the most detailed glimpse of the early universe recorded to date.
    • The collection also included fresh images of another galaxy cluster known as Stephan’s Quintet, first discovered in 1877.

    James Webb Space Telescope

    • JWST is a joint NASA–ESA–CSA space telescope that is planned to succeed the Hubble Space Telescope as NASA’s flagship astrophysics mission
    • It is the most powerful space telescope ever built.
    • It will enable a broad range of investigations across the fields of astronomy and cosmology, including observing some of the most distant events and objects in the universe,
    • It would help understand events such as the formation of the first galaxies, and detailed atmospheric characterization of potentially habitable exoplanets.

    Its significance

    • Some have called JSWT the “telescope that ate astronomy.”
    • It is said to look back in time to the Dark Ages of the universe.

    What does the ‘Dark Ages’ of the universe mean?

    • Evidence shows that the universe started with an event called the Big Bang 13.8 billion years ago, which left it in an ultra-hot, ultra-dense state.
    • The universe immediately began expanding and cooling after the Big Bang.
    • One second after the Big Bang, the universe was a hundred trillion miles across with an average temperature of an incredible 18 billion F (10 billion C).
    • Around 400,000 years after the Big Bang, the universe was 10 million light-years across and the temperature had cooled to 5,500 F (3,000 C).
    • Throughout this time, space was filled with a smooth soup of high-energy particles, radiation, hydrogen and helium.
    • There was no structure. As the expanding universe became bigger and colder, the soup thinned out and everything faded to black.

    This was the start of what astronomers call the Dark Ages of the universe.

    How will JWST study this?

    Ans. Looking for the first light

    • The Dark Ages ended when gravity formed the first stars and galaxies that eventually began to emit the first light.
    • Astronomers aim to study this fascinating and important era of the universe, but detecting first light is incredibly challenging.
    • Compared to massive, bright galaxies of today, the first objects were very small and due to the constant expansion of the universe, they’re now tens of billions of light years away from Earth.
    • Also, the earliest stars were surrounded by gas left over from their formation and this gas acted like fog that absorbed most of the light.
    • It took several hundred million years for radiation to blast away the fog. This early light is very faint by the time it gets to Earth.

  • What is the Nord Stream 1 Gas Link?

    The Nord Stream 1, Germany’s main source of gas from Russia, was recently shut down for scheduled maintenance work.

    Why in news?

    • There are growing concerns in European countries that Russia would shut down its gas supplies in retaliation against the current sanctions against Moscow.

    What is Nord Stream 1?

    • It is a system of offshore natural gas pipelines running under the Baltic Sea from Russia to Germany.
    • Nord Stream 1 is a 1,224 km underwater gas pipeline that runs from Vyborg in northwest Russia to Lubmin in northeastern Germany via the Baltic Sea.
    • Two further pipelines under construction running from Ust-Luga to Lubmin termed Nord Stream 2.
    • Majority owned by the Russian energy giant Gazprom, the pipeline is the primary route through which its gas enters Germany.

    Worry for Europe

    • There have been growing concerns that there could be further restrictions to European gas supplies.
    • European countries rely on Russian energy for their cold winters.
    • But now they believe that Russia could weaponized their dependency as a response to their sanction due to the conflict in Ukraine.

    What are Europe’s alternative sources of energy?

    • As an alternative source for energy, European countries have increasingly turned towards the US, from whom they purchase liquified natural gas (LNG) that comes via ships.
    • Since ship-delivered gas ends up being far more expensive, there are also attempts to get non-Russian pipeline gas from Norway and Azerbaijan.
    • While EU countries were earlier seeking to phase out fossil fuels and emphasize renewable forms of energy, many are now returning to coal to deal with the energy crisis.

  • Sannati and Kanaganahalli Buddhist Sites

    Left almost unattended to for 20 years after excavation, the ancient Buddhist site on the bank of Bhima river near Kanaganahalli (forming part of Sannati site) in Kalaburagi district, has finally got some attention.

    About Sannati

    • Sannati is a small village on the banks of the River Bhima in Chittapur Taluka of Kalaburagi (Gulbarga).

    • The collapse revealed the historically valuable Ashokan edicts written in Prakrit language and Brahmi script at the foundations of the temple, attracting historians from across India.
    • While the Stupa is believed to be one of the largest of its time.
    • The stone-portrait is considered to be the only surviving image of the Mauryan Emperor which had the inscriptionRaya Asoko’ in Brahmi on it.

    Significance of Sannati

    • Further revelations led to the discovery of the magnificent Maha Stupa, which had been referred to as Adholoka Maha-Chaitya (The Great Stupa of the Netherworlds) in the inscriptions.
    • More importantly, a sculpture-portrait of Ashoka seated on his throne with his queens was also discovered.
    • Historians believe that the Sannati Ranamandal (war zone) was a fortified area spread over 210 acres, of which only a couple of acres have been excavated so far.

  • What are Cloudbursts?

    At least eight people have died after a cloudburst occurred at the Amarnath Cave Shrine near Pahalgam in south Kashmir.

    What is a Cloudburst?

    • Cloudbursts are short-duration, intense rainfall events over a small area.
    • According to the IMD, it is a weather phenomenon with unexpected precipitation exceeding 100mm/h over a geographical region of approximately 20-30 square km.

    What causes Cloudburst?

    • A study published last year studied the meteorological factors behind the cloudburst over the Kedarnath region.
    • They analysed atmospheric pressure, temperature, rainfall, cloud water content, cloud fraction, cloud particle radius, cloud mixing ratio, total cloud cover, wind speed, wind direction, and relative humidity during the cloudburst, before as well as after the cloudburst.
    • The results showed that during the cloudburst, the relative humidity and cloud cover was at the maximum level with low temperature and slow winds.
    • It is expected that because of this situation a high amount of clouds may get condensed at a very rapid rate and result in a cloudburst.

    Impact of climate change

    • Several studies have shown that climate change will increase the frequency and intensity of cloudbursts in many cities across the globe.
    • As temperatures increase the atmosphere can hold more and more moisture and this moisture comes down as a short very intense rainfall for a short duration.
    • This results in flash floods in the mountainous areas and urban floods in the cities.
    • Also, there is evidence suggesting that globally short-duration rainfall extremes are going to become more intense and frequent.

  • Derecho: A storm that turned the sky green in the US

    States of Nebraska, Minnesota and Illinois in the US were hit by a storm system called a Derecho which turned the skies green.

    What is a Derecho?

    • A derecho is a widespread, long-lived, straight-line windstorm that is associated with a band of rapidly moving showers or thunderstorms.
    • The name comes from the Spanish word ‘la derecha’ which means ‘straight’.
    • Straight-line storms are those in which thunderstorm winds have no rotation unlike a tornado.
    • Being a warm-weather phenomenon, a derecho generally – not always – occurs during summertime beginning May, with most hitting in June and July.
    • However, they are a rare occurrence as compared to other storm systems like tornadoes or hurricanes.

    Why does the sky turn green during the derecho?

    • Severe thunderstorms result in a ‘green sky’ due to light interacting with the huge amount of water they hold.
    • The big raindrops and hail scatter away all but the blue wavelengths due to which primarily blue light penetrates below the storm cloud.
    • This blue then combines with the red-yellow of the afternoon or the evening sun to produce green.

    Are there different types of derechos?

    They fall into three categories – progressive, serial and hybrid.

    1. Progressive derecho is associated with a short line of thunderstorms that may travel for hundreds of miles along a relatively narrow path. It is a summer phenomenon.
    2. Serial derecho, on the other hand, has an extensive squall line – wide and long – sweeping across a large area. It usually occurs during spring or fall.
    3. Hybrid derecho are that ones have the features of both progressive and serial derechos.

    Where do derechos usually occur?

    • They mostly occur across central and eastern parts of the United States.
    • Derechos have also been documented elsewhere across the world.
    • In 2010, Russia witnessed its first documented derecho.
    • They have also swept through Germany and Finland, and more recently in Bulgaria and Poland.

    A social movement in making

    • Actually the Pasmanda movement in India is 100 years old. A Muslim Pasmanda movement had emerged in the second decade of the last century.
    • After this, in the 90s in India, two big organisations were formed in favour of the Pasmanda Muslims.

  • Environment Protection Act (EPA), 1986

    The Union Environment Ministry proposes to soften the provisions of the EP Act (EPA) by replacing a clause that provides for imprisoning violators with one that only requires them to pay a fine.

    Environment Protection Act (EPA), 1986

    • EP Act was passed under Article 253 of the Constitution, which empowers the Centre to enact laws to give effect to international agreements signed by the country.
    • The purpose of the Act is to implement the decisions of the UN Conference on the Human Environment.
    • They relate to the protection and improvement of the human environment and the prevention of hazards to human beings, other living creatures, plants and property.
    • It was enacted in 1986 on the backdrop of Bhopal Gas Tragedy.
    • The Act was last amended in 1991.

    Why this Act?

    • The Act is an “umbrella” legislation that has provided a framework for the environmental regulation regime in India.
    • It covers all major industrial and infrastructure activities and prohibits and regulates specific activities in coastal areas and eco-sensitive areas.
    • The Act also provides for coordination of the activities of various central and state authorities established under other environment-related laws, such as the Water Act and the Air Act.

  • What is Purchasing Managers Index (PMI)?

    India’s services firms saw growth in new business and output accelerate to a 11-year high in June, as per the survey-based S&P Global India Services Purchasing Managers Index (PMI).

    What is the news?

    • The index rose to 59.2 last month, from 58.9 in May, signalling a strengthening in demand across the services sector, which had borne the brunt of the COVID-19 pandemic.

    Purchasing Managers’ Index (PMI)

    • PMI is an indicator of business activity — both in the manufacturing and services sectors.
    • It is a survey-based measure that asks the respondents about changes in their perception of some key business variables from the month before.
    • It is calculated separately for the manufacturing and services sectors and then a composite index is constructed.
    • The PMI is compiled by IHS Markit based on responses to questionnaires sent to purchasing managers in a panel of around 400 manufacturers.

    How is the PMI derived?

    • The PMI is derived from a series of qualitative questions.
    • Executives from a reasonably big sample, running into hundreds of firms, are asked whether key indicators such as output, new orders, business expectations and employment were stronger than the month before and are asked to rate them.

    How does one read the PMI?

    • A figure above 50 denotes expansion in business activity. Anything below 50 denotes contraction.
    • Higher the difference from this mid-point greater the expansion or contraction. The rate of expansion can also be judged by comparing the PMI with that of the previous month data.
    • If the figure is higher than the previous month’s then the economy is expanding at a faster rate.
    • If it is lower than the previous month then it is growing at a lower rate.

    What are its implications for the economy?

    • The PMI is usually released at the start of the month, much before most of the official data on industrial output, manufacturing and GDP growth becomes available.
    • It is, therefore, considered a good leading indicator of economic activity.
    • Economists consider the manufacturing growth measured by the PMI as a good indicator of industrial output, for which official statistics are released later.
    • Central banks of many countries also use the index to help make decisions on interest rates.
