As of now, scientists have not found definitive evidence of life elsewhere in the universe. However, the discovery of potentially habitable exoplanets and moons suggests that life could exist beyond Earth, and research continues to explore this possibility.
Beyond the Milky Way Galaxy lies a vast expanse filled with other galaxies, galaxy clusters, and cosmic structures. This includes the Local Group of galaxies, the Virgo Cluster, and the broader universe, extending infinitely with numerous celestial objects.
The Indian Astronomical Observatory in Hanle is crucial for advanced astronomical research due to its high altitude, clear skies, and minimal light pollution. It enables precise observations of celestial objects and contributes to significant discoveries in astronomy.
The Indian Institute of Astrophysics chose Hanle, Ladakh, for its observatory due to its clear skies, low light pollution, and minimal atmospheric turbulence. The high altitude also offers excellent visibility and stable weather conditions for astronomical observations.
Increasing light pollution disrupts human sleep, wildlife behavior, and ecosystems. To control it, I would use outdoor lights only when necessary, install motion sensors, and choose LED lights with proper shielding to minimize skyglow and light spill.
The mantle is an organ in snails that secretes the shell. It produces the shell’s calcium carbonate material and contributes to its growth, providing the snail with protection and support.
The shell is crucial for a snail’s survival as it provides protection from predators, prevents dehydration, and offers structural support. Without it, a snail would be vulnerable to various environmental threats.
A snail uses its shell for protection and support. The shell is a hard, external structure that safeguards the snail’s soft body from predators and environmental hazards and helps maintain moisture levels.
Non-living things cannot exhibit true signs of life. While they may appear to display movement or other properties, these are not due to biological processes but are mechanical or chemical in nature.
