Square Kilometer Array project

GS Paper 3: Science and Technology- developments and their applications and effects in everyday life.

Context:
India had decided to formally join the Square Kilometer Array (SKA) project, an international scientific collaboration working to build the world’s largest radio telescope.

India's Role in SKA:-

The decision to join SKA as a full member ensures India’s participation in yet another international mega-science project in the most advanced areas of scientific research.

India had already been contributing to the project for the past several years.

The full member status, which offers greater scientific opportunities to use the upcoming facility, requires countries to sign and ratify an international treaty, and also make a financial commitment.

India has approved Rs 1,250 crore for the project, which includes its funding contribution for the construction phase.


About Square Kilometer Array:-

The Square Kilometer Array is not a single telescope but a collection of thousands of dish antennas.

It functions as one unit, meant to achieve one square kilometre of effective area for collecting radio waves.

Currently, the USD 2.4-billion project will have a lesser collection area than one square kilometre, but the original name remains.

About 200 antennas in South Africa and over 130,000 in Australia are being installed in remote areas to reduce signal interference from Earth-based sources.

Construction began in December 2022, and the first phase of the project is expected to be completed by next year.

The SKA would be much more powerful than the most advanced radio telescopes in similar frequency ranges once operational.


Its Development:

The SKA's development will utilize various surveys conducted by the Australian Square Kilometre Array Pathfinder (ASKAP).

It is a powerful telescope operated by Australia's science agency, the Commonwealth Scientific and Industrial Research Organisation (CSIRO).

ASKAP has been fully operational since February 2019, and it made history by mapping over three million galaxies in a mere 300 hours during its first-ever all-sky survey conducted late last year.

ASKAP surveys are designed to observe galaxies and the hydrogen gas they contain and map the structure and evolution of the Universe.


Significance for India:

India's participation in the international Square Kilometre Array (SKA) project, even though none of the facilities will be located in India, will provide significant science and technology gains for the country.

The SKA, offering the most promising tool for research in astronomy, would be the next logical step forward for Indian scientists working in this area and provide India preferential access to the facilities.

The project would work on the highest-end technologies, generating huge learning opportunities for scientists, academics and private industry.

The intellectual properties generated by the project would be accessible to all member countries.

Participating in the project is expected to expand the science and technology base, along with capacity building and training opportunities.


India’s involvement:-

India has been involved in the SKA project since its inception in the 1990s, contributing to the telescope's design and development and negotiating the SKA Observatory Convention.

India's main contribution is in the development and operation of the Telescope Manager, the software that will run the entire facility.

Plans to establish an SKA regional centre in India are underway.

Indian scientists plan to use the SKA telescopes to study the early universe, galaxy formation and evolution, neutron star physics, and solar sciences.

Over 150 scientists, researchers, and students from various Indian institutions, including private companies, are involved in ongoing science activities related to the SKA.

Baleen whales

Context:
Roughly 19 million years old fossil jaw bone of a baleen whale estimated to be around nine metres in length found, makes it the new record holder from its time.

  • The record holder is the blue whale (Balaenoptera musculus), which can reach lengths of up to 30 metres.
  • That’s longer than a basketball court.


What are baleen whales?
Introduction to Baleen Whales:-
Baleen whales are a unique group of cetaceans distinguished by special epidermal modifications in their mouths known as baleen.
Unlike most mammals that possess teeth, baleen whales exhibit a fascinating exception with their reliance on baleen for filtering food from water.

Baleen Structure and Function:-
Baleen, a substantial rack composed of fine, hair-like keratin, serves as the key tool for baleen whales to filter small krill from the water.
This specialized structure enables efficient feeding on vast shoals of tiny zooplankton in highly productive oceanic regions, contributing to the evolution of increasingly larger body sizes.

Size Comparison with Toothed Whales:-
Baleen whales, in general, surpass toothed whales in size, with the notable exception of the sperm whale, renowned for its impressive size and possessing teeth.

Annual Migration Patterns:-
Many baleen whales engage in annual migration, covering extensive distances between cold-water feeding grounds and warm-water breeding areas.
This behaviour highlights their adaptability and ability to thrive in diverse oceanic environments.

Geographical Aspect of Fossil Record:-

  • Nature and Location of Thylakoids:

Thylakoids are small pouches situated within the chloroplasts of plants.

They serve as essential structures for various processes, particularly photosynthesis.

  • Chlorophyll Storage and Photosynthesis Trigger:

Thylakoids function as storage units for chlorophyll, the plant substance responsible for reacting to sunlight and initiating the process of photosynthesis.

  • Composition and Functionality:

These membranes are dense and primarily composed of galactolipids, forming protein-containing bilayers.

Photosynthesis, a vital process in photosynthetic organisms, occurs within these bilayers.

  • Presence in Ancient Cyanobacteria:

Thylakoids have evolutionary roots and can be traced back to ancient, light-sensitive bacteria known as cyanobacteria.

Cyanobacteria played a crucial role in the oceans billions of years ago and are believed to be responsible for the substantial oxygen stores in the atmosphere, making them precursors to life.

  • Cyanobacteria's Role in Oxygen Production:

The multiplication of cyanobacteria in the oceans is linked to the generation of oxygen on a massive scale.

These bacteria are considered key contributors to the oxygen levels found in the atmosphere, shaping the conditions necessary for life.

  • Thylakoid Membranes and Sunlight Utilization:

Thylakoid membranes in cyanobacteria are believed to be pivotal in enabling these organisms to utilize sunlight for energy production and release oxygen.

This suggests a crucial role for thylakoids in the evolution.



What are Cyanobacteria?
These are commonly known as cyanobacteria, minuscule life forms naturally occurring in various water sources.
Thriving in fresh, brackish, and marine environments, these single-celled organisms harness sunlight to produce their sustenance.
In environments characterized by warmth and a surplus of nutrients, particularly high levels of phosphorus and nitrogen, cyanobacteria can rapidly proliferate.
This leads to the formation of blooms that extend across the water's surface. Cyanobacteria blooms tend to emerge in warm, sluggish waters abundant in nutrients, originating from sources such as fertilizer runoff or septic tank overflows.
Nutrients serve as essential elements for their survival.
Although these blooms can manifest at any time, they are most commonly observed in late summer or early fall.
