Why in News?
Recent research has unveiled a surprising discovery about Betelgeuse that the star's enigmatic brightening and dimming patterns may be caused by an unseen companion star.
About Betelgeuse:
- Betelgeuse is a red supergiant star located in the left shoulder of the constellation Orion.
- It ranks among the brightest stars visible in the night sky and is one of the largest stars ever identified.
- The star is situated approximately 650 light-years away from Earth.
- Betelgeuse is nearing the end of its life span; when it dies, its explosion will be bright enough to be seen during the day for several weeks.
- It is one of the largest known stars, with a diameter exceeding 700 million miles (1.2 billion kilometers).
- Betelgeuse is known for its periodic dimming and brightening.
- The star exhibits two distinct pulsation patterns: a shorter cycle lasting about a year and a longer cycle spanning approximately six years.
- Researchers concluded that the longer cycle, known as the long secondary period, is likely influenced by the orbital motion of a companion star, referred to as Betelbuddy, through the surrounding dust of Betelgeuse.
What is a Red Supergiant Star?
- A red supergiant is formed when a star exhausts its hydrogen fuel for nuclear fusion and begins the dying process.
- These stars are evolved entities with masses ranging from 10 to 25 times that of the Sun.
- A supergiant star can have a diameter several hundred times that of the Sun and a luminosity that can be nearly 1,000,000 times greater.

Why in News?
The Ministry of Health and Family Welfare may amend the Transplantation of Human Organs and Tissues Act (THOTA), 1994, to facilitate retrieval of cornea from all Indian patients who die in hospitals, without consent from the family.
About Cornea:
- The cornea is the clear outer layer located at the front of the eye.
- It serves to cover the pupil, which is the opening at the center of the eye, and the iris, the colored part of the eye, along with the anterior chamber, which is the fluid-filled space inside the eye.
- The primary function of the cornea is to refract or bend light, playing a crucial role in focusing most of the light that enters the eye.
- Its unique shape significantly impacts vision and helps filter out some ultraviolet (UV) rays.
- Aside from its edges, the cornea lacks blood vessels but is rich in nerve endings, making it very sensitive to pain and touch.
- Since the cornea does not possess blood vessels to supply nutrients, it relies on tears and the aqueous humor, a watery fluid in the anterior chamber, to receive nourishment.
- As light passes through the cornea, it is partially refracted prior to reaching the lens of the eye.
- The curvature of the cornea, which is spherical during infancy, changes with age and is responsible for its focusing ability.
- When the curvature becomes irregular, it leads to a visual defect known as astigmatism, where images may appear elongated or distorted.
- The cornea acts as the first line of defense for the eye's surface, making it susceptible to injuries and damage.
- Minor abrasions on the cornea tend to heal quickly, but deeper scratches can lead to scarring, which compromises the cornea's transparency and can cause visual impairment.

The SC's Verdict on Madarsa Education Act
Source: Indian Express
Why in news?
The Supreme Court of India (SC) has reserved its judgement regarding the constitutionality of the Uttar Pradesh (UP) Board of Madarsa Education Act, 2004. This ruling is crucial as it addresses significant issues concerning secularism, the right to education, and how religious education aligns with modern educational standards in India.
What is the UP Madarsa Education Act 2004?
- The Act regulates the educational activities in madarsas, which are institutions that provide religious education along with some secular subjects, albeit with a focus on religious teachings.
- It established the UP Board of Madarsa Education, primarily comprising members from the Muslim community, which is tasked with creating the curriculum and overseeing examinations for various madarsa courses, from 'Maulvi' (equivalent to Class 10) to 'Fazil' (equivalent to a Master’s degree).
Status of Madarsas in UP:
- Uttar Pradesh has the highest number of madarsas in India, with about 1.69 lakh students enrolled in over 14,000 recognized institutions, participating in board exams equivalent to Class 10 and Class 12 in 2023.
The Madarsa Education Act declared unconstitutional:
- In March 2024, the Allahabad High Court ruled the 2004 Act unconstitutional, mandating the integration of madarsa students into the mainstream education system.
- The SC temporarily stayed this ruling in April 2024 and commenced hearings in October, also halting notifications from the National Commission for the Protection of Child Rights (NCPCR) regarding inspections of madarsas and the inclusion of non-Muslim students.
On What Grounds Allahabad HC Declared Madarsa Act Unconstitutional:
- Violation of secularism: The HC emphasized that secularism entails equal treatment of all religions by the state. The madarsa curriculum was criticized for making Islamic education compulsory while relegating modern subjects to optional status, conflicting with the state's obligation to provide secular education.
- Violation of the right to education: The court stated that the Act infringed upon Article 21A of the Indian Constitution, which guarantees free and compulsory education to children aged six to fourteen. It pointed out that the education quality in madarsas fell short of the standards defined by the Right to Education (RTE) Act, 2009.
- Conflict with the UGC Act: The provisions of the Madarsa Act were found to be inconsistent with the University Grants Commission (UGC) Act, 1956, which limits degree conferral to recognized universities. Thus, the madarsa board's authority to grant degrees was deemed unconstitutional.
Key Arguments on the Constitutionality of the Madarsa Education Act Before the SC:
- Religious education vs. religious instruction: A central debate was whether madarsas provide "religious education," which is permitted, or "religious instruction," which is prohibited in state-funded institutions. The distinction is vital as Article 28 of the Constitution forbids religious instruction in such contexts.
- Striking down the entire Act: Another significant discussion revolved around whether the HC's decision to strike down the entire Act was appropriate or if only specific unconstitutional provisions should have been nullified. Chief Justice D.Y. Chandrachud pointed out that the state could regulate madarsa education to align with secular principles without entirely abolishing the Act.
Wider Implications of the SC's Decision on the Madarsa Education Act:
- The SC's decision is expected to have national consequences beyond UP, impacting the interaction between religious education and secularism.
- This case raises broader questions about the state's role in ensuring that all children, regardless of religious backgrounds, receive a modern, secular education.
- The ruling could also influence other religious educational institutions such as gurukuls and convent schools that blend religious teachings with their curricula.
- Chief Justice Chandrachud cautioned that the principles of secularism must be carefully considered when regulating religious instruction.
Conclusion:
- The upcoming judgement from the SC on this matter could establish a significant precedent for the future of religious education in India, potentially reshaping the coexistence of religious and secular education in the country's diverse educational framework.
