Galaxy Messier 82 (M82), also known as the cigar galaxy

Scarlet plumes of hydrogen emanate from the lively cosmic portrait of the galaxy Messier 82 (M82) shown above. Also known as the cigar galaxy, it sits in the constellation Ursa Major, around 12 million light years away.

It is what is known as a starburst galaxy due to its remarkably high rate of star formation. In fact, for every star born in the Milky Way, 10 burst into existence in M82. The reason for this much greater activity ***** in M82’s gravitational interactions with a neighbouring galaxy known as M81.

The fantastic image here is the sharpest wide-angle view of M82 ever captured. It was assembled using shots taken by NASA’s Hubble Space Telescope in both infrared and visible wavelengths of light.

Cat’s Eye Nebula

Glowing with an ethereal beauty is the Cat’s Eye Nebula, or NGC 6543, (pictured above) which was also imaged by Hubble. It is a planetary nebula. Despite the name, these are nothing to do with planets, but form when sun-like stars vigorously expel their outer layers of gas to form a spectacular display. This nebula’s concentric, pastel-********* rings are shells of material emitted in a series of pulses, with around 1500 years between each event.

Both these magnificent scenes feature in the upcoming book

“I hope readers will take away both a sense of wonder at how incredible, vast and beautiful our universe is,” says astrophysicist Becky Smethurst, who wrote the book’s foreword, “but also a sense of how much there is that we still don’t know about our universe.”
