SOLAR HALO PHENOMENON
Nature's magic! Waterfall appears to emerge from sky; breathtaking video from giant Brazilian cave leaves viewers amazed
A video filmed inside Brazil’s Casa de Pedra cave has captured an unusual sight, with a waterfall appearing to pour straight out of a rainbow in the sky. The footage shows water falling from a crack in the rock above the cave entrance, while a colourful solar halo circles the Sun and another rainbow-like arc appears nearby. Located in Iporanga, Sao Paulo state, the cave is part of Alto Ribeira Tourist State Park and is known for its enormous entrance, which rises around 170 to 200 metres high. Here is how the cave’s setting, falling water and atmospheric optical effects create the striking illusion.

Vikram lander raised lot of dust during moon landing, created halo
"During the action of descent stage thrusters and the consequent landing, a significant amount of lunar surficial epiregolith material got ejected, resulting in a reflectance anomaly or 'ejecta halo'," scientists at the National Remote Sensing Centre (NRSC) said in the paper. They estimated that the landing event had ejected 2.09 tonnes of lunar regolith over 108.4 square metre area.
