Encounter with the Cigar Galaxy

An astronomical journey introduces us to the Cigar Galaxy, also recognized as M82, one of the most striking galaxies outside our own Milky Way. The Cigar Galaxy offers a stunning spectacle, a unique exploration in the universe.

Astounding Details about M82

The Discovery of the Cigar Galaxy

The Cigar Galaxy, uncovered by Johann Elert Bode in 1774, is 12 million light- years away from Earth, in the constellation Ursa Major. Bode, therefore, laid the foundation for our understanding of the extraordinary features of M82.

Why the Name ‘Cigar Galaxy?’

The ‘Cigar’ nickname arises from the elongated, cigar-shaped appearance of the galaxy when viewed through a telescope. This unique shape is due to the intense star formation activity within, earning M82 the label of ‘starburst galaxy.‘

The Starbirth Phenomenon

In the M82 galaxy, stars are born at a rate ten times higher than that in our own galaxy. Its core is a high energy, a high-density hub, emitting huge amounts of infrared radiation due to this cosmic birth-rate.

Unique Aspects of M82

• The central region of the galaxy exudes bright blue and red emitted by hot young stars and ionized hydrogen.
• Two jet streams of super-hot gas are emitted from the poles, visible only in radio and infrared wavelengths.
• The galaxy’s plane is filled with dark dust lanes intersecting its vibrant core, creating a dramatic contrast.

Visibility of M82

Despite its relative dimness and distance, the Cigar Galaxy is still visible to amateur astronomers using small telescopes or high-powered binoculars. Its distinctive elongated shape and high surface brightness help it stand out in the night sky.

Binocular Viewing of M82

A careful observer under a clear, dark sky can make out the vague, nebulous smudge of the Cigar Galaxy using a good pair of binoculars. Though the detailed structure will be elusive, the thrill of locking your sight onto another galaxy is an experience beyond words.

M82 Through a Telescope

Viewing M82 through a small or medium-sized telescope under a dark sky reveals its iconic elongated shape. Larger, more powerful telescopes reveal the mottled structure of the galaxy, providing glimpses of the tumult within.

Observing M82: The Astronomer’s Tip

Choosing a clear, moonless night and finding a location far from city lights significantly improve your chances of a vibrant encounter with this celestial wonder.

Decoding the Mysteries of M82

Scientists are still working to decipher many of the secrets locked within the Cigar Galaxy. M82’s unusual properties are a key focus for astronomers studying galaxy evolution, and its starburst activity provides valuable insights into the ultimate fate of our own galaxy.

FAQs About the Cigar Galaxy
