Hubble’s Bubble

Hubble’s Bubble
To celebrate 26 years in space, Hubble has captured this magnificent view of NGC 7635, better known as the Bubble Nebula.
It looks like a giant, glistening, soap bubble blown into the night sky. In reality, it’s a cloud of gas and dust 10 light-years across that exists around 8,000 light-years away in our Milky Way galaxy.

Known as the Bubble Nebula, the wispy-looking shell surrounds an off-centred star whose mass is more than ten times that of our sun. The plasma thrown out by this star, its so-called stellar wind, is responsible for forming the “bubble”, while its intense radiation causes the gas to glow.
