A Bubble in Space ?

You read it right, a bubble in space.It’s Bubble Nebula also called as NGC 7635.It’s an H II region (regions of star formation), but what lead to that shape? There is a massive, hot, young star at its center and the bubble is created by stellar wind from this star. It was discovered by William Herschel in 1787.The star SAO 20575 is thought to have the mass of 10-40 solar masses. With an 8 or 10-inch (250 mm) telescope, the nebula is visible as an extremely faint and large shell around the star.

The universe is full of surprising and amazing shapes. It’s an artist, which is limitless and has no boundaries to its art.
