There are also examples from galaxies undergoing starbursts.
K

The galaxy M82, the Cigar Galaxy, is one of the best studied starburst galaxies.
K
75:33KeithNARRATOR
It's undergoing an intense burst of star formation, probably triggered by gravitational interactions with its neighbor, M81.
K
75:43KeithNARRATOR
M82 has a galactic superwind, hot gas streaming out perpendicular to its disk, visible in X-rays, optical and radio wavelengths.
K
75:53KeithNARRATOR
This wind is driven by supernova explosions from all the massive stars forming and dying in the galaxy's center.
K
76:00KeithNARRATOR
The structure looks remarkably similar to the structures.
K
77:05KeithNARRATOR
Elliptical galaxies are surrounded by enormous halos of hot gas, and their black holes are often much more massive and powerful than ours.
K
77:15KeithNARRATOR
By comparing the Milky Way to these other systems, we can understand where our galaxy fits in the bigger picture.

Despite its relatively close distance, The Sombrero has puzzled astronomers because its star population suggests it is older than most nearby spiral galaxies.
K
92:20KeithNARRATOR
The cigar galaxy, M82, is a starburst galaxy about 12 million light years away.
K
92:28KeithNARRATOR
It is undergoing intense star formation, triggered by a gravitational interaction with its larger neighbor, M81.
K
92:36KeithNARRATOR
Stars are forming in M82 at a rate about 10 times higher than in typical galaxies.
K
92:43KeithNARRATOR
This activity is visible as jets of hydrogen gas streaming out from the galaxy's core, extending thousands of light years into intergalactic space.

Centaurus A, is one of the nearest radio galaxies at about 13 million light years.
