Of those, my favorites are a celestial version of The Odd Couple: M81 and M82 in Ursa Major. Nowhere else in the sky do we find such an unusual pair. On one hand, we have a textbook example of a ...

This is likely the result of a close encounter within the past few hundred million years with its larger neighbor galaxy M81 (magnitude 6.9, about two-thirds of a degree south of M82). In the ...

Astronomers using the Subaru Telescope’s Hyper Suprime-Cam prime-focus camera recently observed the nearby large spiral galaxy M81, together with its two brightest neighbors, M82 and NGC 3077.

(M31 is larger.) Need a break? Play the USA TODAY Daily Crossword Puzzle. Two other neighboring galaxies, M81 and M82, may be seen in binoculars on a dark, clear spring evening. They are not far ...

This deep view of Bode's Galaxy (M81; center), the Cigar Galaxy (M82; lower left), and NGC 3077 (lower right) is the result of more than 59 hours of HαLRGB exposure split across a a 3.3-inch ...

The spiral galaxy M81 and its satellite, M82, are seen in visible light (white); intergalactic hydrogen gas revealed by the GBT is shown in red; and additional hydrogen gas earlier detected by the ...

Astronomers using the Subaru Telescope's Hyper Suprime-Cam observed the nearby large spiral galaxy M81, together with its two brightest neighbors. The team obtained deep and super wide-field ...

The objects are known as the galaxies, M81 and M82, from the classic Messier list of celestial objects. Charles Messier was a French astronomer who cataloged a series of well over 100 objects ...

The last closest one was Supernova 1993E, first observed in 1993 in the galaxy M81, which, like M82, is about 12 million light-years away. Before that, Supernova 1987A appeared in February 1987 ...
