Best 1 Tarantula Nebula (30 Doradus)

The Tarantula Nebula, designated as 30 Doradus, is a massive H II region and emission nebula located in the Large Magellanic Cloud. It is the most active starburst region within the Local Group of galaxies, containing a high concentration of massive stars and the dense star cluster R136. The nebula...

2 SN 1987A Nebula

SN 1987A is the remnant of a Type II supernova that occurred in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, in February 1987. It is the closest observed supernova since the invention of the telescope, providing astronomers with an unprecedented opportunity to study the death of...

3 Tarantula Nebula (NGC 2070)

The Tarantula Nebula, formally NGC 2070, is a prominent emission nebula situated in the Large Magellanic Cloud. It’s notable as the most active starburst region within our Local Group of galaxies. This dense cloud is approximately 160,000 light-years distant and exhibits intense star formation, far...

4 N44 Nebula (LMC)

The N44 Nebula is a large emission nebula complex located in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. It spans roughly 1,000 light-years and is classified as an H II region, indicating active star formation. The nebula's most distinguishing feature is a massive central superb...

5 N11 (in LMC)

N11 is a massive emission nebula complex situated within the Large Magellanic Cloud (LMC), a dwarf satellite galaxy of the Milky Way. It is the second-largest star-forming region in the LMC, following the Tarantula Nebula. The complex is characterized by its bright, ring-like structures and clusters...

6 N11 (LMC)
N11 (LMC)

N11 is a prominent ring-shaped emission nebula and H II region located within the Large Magellanic Cloud, a satellite galaxy of the Milky Way. Recognized as the second largest star-forming region in the LMC after the Tarantula Nebula, it contains multiple bright clusters of newly formed stars. Its d...

7 N44 (in LMC)

N44 is a vast H II emission nebula located within the Large Magellanic Cloud, a nearby satellite galaxy of the Milky Way. It is particularly notable for its distinctive central void, a cavity measuring dozens of light-years across, which was carved out by intense stellar winds from young, massive st...

8 N49 (in LMC)

N49 is a supernova remnant in the Large Magellanic Cloud that is notable for containing a soft gamma-ray repeater, an extremely rare type of neutron star.

9 NGC 2020
NGC 2020

NGC 2020 is an emission nebula in the Large Magellanic Cloud, notable for its striking ring-like shape sculpted by massive stellar winds.

10 N70 (LMC)
N70 (LMC)

N70 is a luminous superbubble nebula located in the Large Magellanic Cloud, formed by the combined stellar winds of numerous massive stars and supernovae.

11 NGC 595 (M33)

NGC 595 is an expansive H II region within the Triangulum Galaxy, notable for its intense star formation and discovery by astronomer Heinrich d'Arrest in 1861.

12 NGC 2020 (LMC)

NGC 2020 is an emission nebula located in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. It is distinguished by its striking blue hue, which contrasts visually with the neighboring reddish nebula NGC 2014. The blue coloration is created by the intense stellar winds and ultraviolet...

13 NGC 2014 (LMC)

NGC 2014 is a massive emission nebula situated in the Large Magellanic Cloud. It is characterized by its reddish glow, which results from the ionization of hydrogen gas by young, hot stars embedded within the cloud. The nebula is frequently observed alongside the neighboring blue emission nebula NGC...

14 N70 (in LMC)

N70 is a superbubble nebula within the Large Magellanic Cloud, notable for its enormous size and the combined stellar winds that created it.

15 Christopher Impey

Christopher Impey is an American astronomer and educator at the University of Arizona, widely recognized for his extensive research on quasars and popular science books on astrobiology.

16 DEM L190 (LMC)

DEM L190 is a notable supernova remnant located in the Large Magellanic Cloud, recognized for its distinct filamentary structure and complex X-ray emissions.

17 N49 (LMC)
N49 (LMC)

The brightest supernova remnant in the Large Magellanic Cloud, notable for hosting soft gamma repeater SGR 0526-66 and displaying an asymmetric, filamentary shock shell.

18 N63A (LMC)
N63A (LMC)

A supernova remnant in the Large Magellanic Cloud and one of its brightest X-ray sources, embedded within the active star-forming complex N63.
