  • First ‘Black Hole Triple’ System Discovered

    Scientists have discovered a “black hole triple” in space, marking the first time such a system has been identified.

    Why in the News?

    Scientists have discovered a “black hole triple” in space, marking the first time such a system has been identified.

    Black Hole Triple: What does it mean?

    • Many black holes are found in binary systems with another star or black hole.
    • This triple system includes two stars orbiting a black hole:
      • The nearer star orbits the black hole every 6.5 days.
      • The distant star orbits approximately every 70,000 years.
    • The system, located in the constellation Cygnus, features V404 Cygni, one of the oldest black holes known, which is nine times larger than the Sun.
    • It is 8,000 light years away from Earth.

    What is a Black Hole?

    • A black hole is a space region with such strong gravity that no light or matter can escape.
    • Most black holes form from supernova explosions—the death of massive stars.
    • This triple system suggests an alternative, less violent formation process.

    How was it discovered?

    • Researchers from Caltech and MIT discovered the system while reviewing astronomical data from telescopes.
    • They described the stars as being gravitationally bound, indicating they form a triple system.
    • It is believed that  V404 Cygni did not form through a supernova explosion, which typically ejects outer stars.
    • Instead, it likely formed through direct collapse: the star collapsed inward without exploding.
    • Known as a “failed supernova”, this process causes an implosion without expelling matter, leading to a gentler black hole formation.

    Future of the Triple System

    • The triple system may not remain as such, as V404 Cygni is consuming the nearby star.
    • This discovery suggests that some existing binary systems may have originally been triple systems, where the black hole later consumed one of its members.

    PYQ:

    [2019] Recently, scientists observed the merger of giant ‘blackholes’ billions of light-years away from the Earth. What is the significance of this observation?

    (a) ‘Higgs boson particles’ were detected.
    (b) ‘Gravitational waves’ were detected.
    (c) Possibility of inter-galactic space travel through ‘wormhole’ was confirmed.

  • The Gompertz Model

    Why in the News?

    Indian researchers have developed a predictive model based on the Gompertz Model to estimate a newborn’s birth weight using routine pregnancy scans.

    What is the Gompertz Model?

    • It is a mathematical model developed by English mathematician Benjamin Gompertz in the early 19th century.
      • It was originally designed to model population growth in a constrained environment, such as a specific geographic region.
      • The model uses an S-shaped (sigmoid) curve to represent growth patterns that start slowly, accelerate, and then slow again as they approach a plateau.
    • Applications:
      • Biology: The Gompertz Model is used to study tumor growth and cell population dynamics, reflecting constrained growth in biological systems.
      • Epidemiology: Applied in predicting the spread of infectious diseases like COVID-19, capturing how transmission rates slow with interventions.
      • Ecology: Useful for modelling species population growth in habitats with limited resources, aiding conservation and ecosystem management.
      • Healthcare: Recently adapted to predict foetal birth weight, helping identify potential risks associated with low or high birth weight.
      • Aging Research: Employed to analyze mortality rates and lifespan patterns, contributing to studies on aging and longevity.

    Recent Research and Significance

    • Recent research has applied the Gompertz Model in predicting foetal birth weight using routine scans, as shown by researchers from IISER Pune and IMSc Chennai, offering a non-invasive alternative for maternal health.
    • The model is used in tumor growth studies, allowing researchers to understand and predict cancer progression.

  • Glacial Lakes rise as glaciers retreat

    Why in the News?

    Since 1977, the South Lhonak Lake, a glacial lake in Sikkim has expanded significantly, growing from 17 hectares to 167 hectares by 2023.

    Formation of Glacial Lakes:

    • When a glacier melts and retreats, the hollow left behind often fills with water, creating a glacial lake.
    • The rocky moraine at the glacier’s end can act as a natural dam, holding the water to form the lake.
    • Glacial lakes act as hydrological buffers, regulating water flow from melting ice, which can sometimes pose challenges to downstream communities.
    • Glacial lakes often have a vivid blue color, similar to swimming pools, due to the scattering of light by fine rock particles (rock flour) in the water.
    • There are several types of glacial lakes, each formed by specific processes and glacier dynamics:
      • Moraine-Dammed Lakes: Formed when moraine debris piles up at the end of a glacier and traps meltwater behind it. These are common and pose risks of outburst flooding.
      • Kettle Lakes: This was created when a chunk of glacier ice is buried in the moraine and eventually melts, leaving a depression filled with water.
      • Cirque Lakes: Formed in circular basins (cirques) carved by glaciers at high elevations. These lakes are often small and located at the glacier’s original head.
      • Pro-glacial Lakes: Situated in front of the glacier, between the ice and the moraine dam. These lakes are sometimes formed when the glacier’s snout melts and deposits water in the valley.
      • Tarn Lakes: Formed in depressions left behind in the cirques or basins after the glacier has completely melted.

    Major Glacial Lakes in India

    India’s Himalayan region is home to numerous glacial lakes, each with unique characteristics:

    • Gurudongmar Lake (Sikkim): One of the highest lakes in the world at 5,430 meters above sea level, fed by glacial melt and known for its religious significance.
    • Chandra Taal (Himachal Pradesh): A stunning crescent-shaped lake in the Lahaul-Spiti region at 4,300 meters. It is surrounded by snow-capped mountains and fed by glacier melt.
    • Samiti Lake (Sikkim): Located along the trek to Kanchenjunga and known for its clear blue waters and reflective quality.
    • Satopanth Tal (Uttarakhand): Found in the Garhwal Himalayas, this lake lies close to Satopanth Glacier and is considered sacred by locals.
    • South Lhonak Lake (Sikkim): A growing lake fed by three glaciers, expanding rapidly due to climate change and posing risks of glacial lake outburst floods.

    • Regulation of Development Activities: State governments needs to enforce stringent regulations on construction activities to prevent encroachments and protect wetlands and other sensitive areas.
    • Restoration Projects: Need to develop programs that focus on restoring degraded habitats, such as montane grasslands and shola forests, which are critical for biodiversity.
    • Water Resource Protection: Need to implement measures to safeguard water bodies from pollution and encroachment, recognizing that the Nilgiris are vital water sources for surrounding regions.
      •  For example, restoring wetland areas that have been converted for agriculture or development, enhancing their capacity to retain water and support biodiversity.

    Way Forward: By recognizing the interconnectedness of culture and ecology, there is potential to develop sustainable practices that honor both the natural environment and the rich heritage of its inhabitants. The path forward lies in fostering collaboration and promoting awareness about the importance of conserving this unique biosphere for future generations.
