Carbon dating
- Principle: Carbon dating, also known as radiocarbon dating, relies on the principle of radioactive decay of carbon isotopes in organic materials.
- Carbon Isotopes: Carbon-14 (C-14) is a radioactive isotope of carbon that is naturally occurring and unstable. It decays at a known rate over time.
- Formation: Carbon-14 is formed in the upper atmosphere when cosmic rays interact with nitrogen atoms, producing C-14.
- Incorporation in Organisms: Plants absorb carbon dioxide from the atmosphere during photosynthesis, and animals acquire carbon by consuming plants or other animals.
- Stable to Radioactive Ratio: While an organism is alive, the ratio of C-14 to stable carbon isotopes (C-12 and C-13) remains constant in its tissues due to continuous exchange with the environment.
- Decay Process: After the organism dies, it no longer exchanges carbon with the environment. The C-14 in its tissues begins to decay at a predictable rate.
- Half-Life: Carbon-14 has a half-life of approximately 5,730 years, meaning that half of the C-14 atoms in a sample decay into nitrogen-14 over that period.
- Measuring Decay: By measuring the remaining ratio of C-14 to stable carbon isotopes in a sample, scientists can calculate the age of the organic material.

WHITE DWARF
TOPIC: (GS3) SCIENCE AND TECHNOLOGY – SOURCE: INDIAN EXPRESS
Astronomers have announced the identification of four white dwarf stars belonging to a newly uncovered and uncommon spectral subclass known as DAQ.
Formation and Composition:
- White dwarfs are remnants of dying stars that have exhausted their nuclear fuel and shed their outer layers to form a planetary nebula.
- They are what stars like the Sun evolve into after they complete their main sequence phase.
Characteristics:
- White dwarfs no longer undergo nuclear fusion but remain incredibly hot due to residual heat.
- Despite being about half as massive as the Sun, they are only slightly larger than Earth, making them extremely dense.
- They rank among the densest objects in the universe, second only to neutron stars.
Internal Structure:
- White dwarfs initially consist of helium, carbon, and oxygen nuclei surrounded by highly energetic electrons.
- Unlike other stars, they are supported against gravitational collapse by electron degeneracy pressure, a result of the Pauli exclusion principle.
Evolution and Cooling:
- Without accreting matter from nearby stars, white dwarfs cool over billions of years.
- Eventually, they are predicted to become ‘black dwarfs,’ though none are expected to exist yet due to the universe’s age.
Cosmological Significance:
- The luminosity of white dwarfs helps astronomers estimate the age of star formation in a region.
- They serve as important astronomical tools, providing fossil records of the stars they originated from.
Observations:
- In 2006, the Hubble Space Telescope observed white dwarfs in globular star clusters, identifying them as the dimmest stars ever seen in such clusters.
