K2-18B: A Rare Exoplanet That Could Support Life

Astronomers have discovered approximately 3,706 exoplanets to date; however, none have shown conditions similar to those of Earth. Among these discoveries, K2-18b stands out as a particularly unique and rare find — a planet with characteristics that suggest it could potentially support life.

Discovery and Location
K2-18b was discovered by NASA’s Kepler Space Telescope and is located approximately 110 light-years away from Earth. What makes this exoplanet remarkable is that it lies within the habitable zone of its star — the region where conditions might be right for liquid water to exist, a key ingredient for life as we know it.

Habitability and Distinctions
K2-18b is the first known exoplanet situated outside our solar system that exhibits both water vapor in its atmosphere and temperatures that may allow for liquid water to exist. However, this does not make it an “Earth twin.” In fact, K2-18b and Earth are vastly different.

K2-18b is approximately 2.3 times wider than Earth and nearly eight times more massive. It orbits a red dwarf star, which is significantly smaller and dimmer than our Sun. Despite the planet’s potential to host life, the environmental and atmospheric conditions remain uncertain.

Temperature Estimates
Temperature assessments by Tsiaras’s team (University College London) suggest the planet’s surface temperature could range between -100°F to 116°F. This wide estimate underscores the current limits of our observational capabilities and the need for more research.



Curiosity: How Many Earth-like Planets Exist in Space?

If your curiosity still isn’t letting you sleep, and you wonder how many more Earth-like planets may exist in the vastness of space — you’re not alone. Scientists are continuously using advanced telescopes and observational methods to search for habitable worlds. While K2-18b is a promising candidate, the search for Earth's true twin continues.

If you'd like an answer to that question — just ask.

Following this success, Chandrayaan-2 became India’s second moon mission, launched in 2019. It was decided that the mission would be carried aboard a GSLV rocket from the Satish Dhawan Space Center in Sriharikota. Origin Initially, Chandrayaan-2 was planned as a collaborative mission between ISRO and Russia. An agreement was signed in 2007 between the two agencies to jointly develop and launch the orbiter and lander in 2013. However, according to  The Hindu , the Russian space agency Roscosmos faced significant delays...

HATHRAS RAPE AND MURDER: CREMATION IS AT STAKE

We enjoy autonomy to make decisions during our lifetime—and this extends even to our bodily integrity after death through legal instruments like wills. Growing up in a democratic country, we recognize the importance of fundamental rights. Our Constitution has expanded its horizons to grant the right to posthumous bodily integrity, reinforcing the value of dignity in death. Since the landmark judgment in  Parmanand Katara v. Union of India & Ors.  (1989), the right to a decent burial has been interpreted as part of the right to live with dignity under Article 21 of the Constitution. The Supreme Court has upheld this interpretation in several subsequent rulings. Furthermore, in  Ashray Adhikar Abhiyan v. Union of India  (2002) , the Court held that the State is under an obligation to ensure proper burial in accordance with the religious beliefs of...
