1/2 Lakshmi Planum: Rising 3–4 km above Venus's mean planetary radius in Ishtar Terra, Lakshmi Planum is a massive volcanic plateau. Framed by tectonic orogens like Maxwell Montes and volcanic patera, it provides key insights into Venusian geodynamics. Lakshmi Planum in dark red
Creating sparks of curiosity in young minds!
Bharath A J recently addressed students at RVCE, exploring key concepts in astronomy and space science. Incredible energy and sharp questions from the next generation of space enthusiasts!
A wonderful outreach session at RV College of Engineering with the members of the Dhruva Astronomy Club on November 6th.
How can you safely observe the Sun without risking your eyes? ☀️🔭
Last Sunday at ABAA, President Ravindra Aradhya demonstrated front-aperture solar filtering, eyepiece projection for sunspot tracking, and this week’s asteroid targets!

Why do sun halos always form at a precise 22° angle, and how do rainbows actually work? ☀️🌈❄️
Last Sunday at ABAA, member Somil Gupta led an interactive session on Atmospheric Optics! Here is the breakdown 🧵👇

Fun Fact: Because a rainbow relies on your specific eye angle to the anti-solar point, no two people ever see the exact same rainbow! 🤯
Have you ever photographed a halo or a sundog? 📸
