NASA's Perseverance rover captures never-seen-before Sun Halo on surface of Mars

<p>The skies of the Indian city Dehradun were graced by an awe-inspiring phenomenon on Sunday. On Sunday afternoon, locals reported seeing a sun halo with a rainbow of colours. This soon prompted many to capture the rare sight on their devices and post it on social media, where it quickly went viral, reported PTI.&nbsp;The sun halo, also known as the "22 degree halo," is an unusual optical phenomenon that gives the appearance of a rainbow encircling the sun or moon at a distance of about 22 degrees.</p>

<p>Director of the Meteorological Centre Bikram Singh explained&nbsp;that the phenomenon happens as a result of sunlight getting refracted by the millions of hexagonal ice crystals hovering in the atmosphere.</p>

<p>Experts advise that people must exercise caution when taking photos of sun halos. Directly facing the sun without any obstructions can harm a camera and your eyes.</p>

<p>As per the website EarthSky, both refraction, or the splitting of light, and reflection, or the glints of light from these ice crystals, result&nbsp;in the halos we witness. For the halo to emerge, the crystals must be precisely aligned and placed in relation to the observer’s eye.</p>
