The question of whether life exists beyond Earth remains one of the greatest mysteries in science. Astronomers and astrobiologists around the world continue the search for alien life by studying planets, moons, and distant star systems for signs of habitability. At RAAVANA, the search for extraterrestrial life is viewed as a key scientific pursuit that…

Beyond our atmosphere lies a dynamic environment filled with Near-Earth Objects (NEOs). At RAAVANA, we act as the sentinels of our planet, dedicated to the detection and tracking of comets and asteroids that cross Earth's orbital path. Understanding the composition and trajectory of these celestial bodies is not just a scientific pursuit; it is a…

Every mission into the unknown reaches a defining "moment of truth"—that critical instant where years of engineering, training, and courage are put to the ultimate test. For American space travelers, this moment often occurs during the high-stakes phase of atmospheric re-entry or the final seconds of a lunar touchdown. At RAAVANA, we study these pivotal…

The 21st century has transformed astronomy through advanced telescopes, space missions, and data-driven research. These discoveries have reshaped our understanding of the universe, from distant galaxies to the fundamental nature of space and time. At RAAVANA, such breakthroughs are closely followed to support Sri Lanka’s growing involvement in space science and research innovation. Key Astronomical…

Recent multi-source climate datasets, including satellite observations, ground-based measurements, and ocean monitoring systems, have confirmed historic records in global climate indicators. These include sustained increases in global mean surface temperature, ocean heat content, sea surface temperature anomalies, and atmospheric CO₂, CH₄, and N₂O concentrations. The accumulation of excess heat within the Earth system indicates a…

Astronomy continues to uncover phenomena that extend far beyond current theoretical frameworks and observational capabilities. Despite major advancements in astrophysics, cosmology, and space technology, a significant portion of the universe remains unobserved, unexplained, and poorly understood. Modern observations indicate that ordinary (baryonic) matter accounts for less than 5% of the universe, while dark matter and…
