Rare 'seasonal blue moon' to light up the sky this weekend, know more here

The rare 'seasonal full moon' will be visible in the sky for two successive evenings over the weekend do not miss the rare celestial event cause as the saying goes they only come around once in a blue moon.

New Delhi: As most of us think that a 'Blue Moon' is the second full Moon of the same month, it’s actually the third of four full moons in a single season, as astronomy. So, prepared for the rare 'seasonal full moon' in the sky as a near-full orb on two successive evenings for the weekend on August 21 and 22.  According to NASA, we get a "seasonal blue moon" once every 2.5 to three years, and luckily thats what the skygazers will be treated to on the weekend.  There are actually two types of blue moons — seasonal and monthly — and both are rare celestial events, but a seasonal blue moon is just slightly more rare than a monthly one, making Sunday's celestial event all the more exciting.
