M100

A "grand design" spiral galaxy that presents an intricate structure, with a bright core and two prominent arms, showing numerous young and hot massive stars, as well as extremely hot knots. Two smaller arms are also seen starting from the inner part and reaching towards the larger spiral arms.

The galaxy, located 60 million light years away, has a diameter of about 120,000 LY, compared with the Milky Way's 100,000.

M100 is considered one of the most prolific galaxies as far as supernovae are concerned. On average, six supernova explosions are recorded in the galaxy in a century.
