Best Variable Nebula
NGC 2261, commonly known as Hubble's Variable Nebula, is a fan-shaped reflection nebula located in the constellation Monoceros. Its shifting appearance is driven by dense clouds of dust passing close to the illuminating variable star R Monocerotis. It was notably studied by Edwin Hubble in 1916 and...
The Hubble’s Variable Nebula, formally designated NGC 2261, is a reflection nebula located in the Monoceros constellation. It's notable for its fluctuating brightness observed by Edwin Hubble in 1916, a key piece of evidence supporting his theories about extragalactic distances. Astronomers and rese...
The R Coronae Australis Nebula is a cloud of interstellar gas and dust in the constellation Corona Australis, associated with the young variable star R Coronae Australis. Its best known component, NGC 6729, is a variable reflection and emission nebula whose apparent brightness and shape can change a...
NGC 6729 is a variable emission and reflection nebula located within the Corona Australis molecular cloud complex. Discovered by astronomer Julius Schmidt in 1861, the cloud's illumination is driven by the variable young T Tauri star R Coronae Australis. As the brightness of R CrA fluctuates, the as...
Hind's Variable Nebula is NGC 1555 in Taurus, a reflection nebula lit by T Tauri and discovered by John Russell Hind in 1852.
Hubble's Variable Nebula, designated NGC 2261, is a fan-shaped reflection nebula located in the constellation Monoceros. It was first recognized for its changing appearance by astronomer Edwin Hubble in 1916, based on photographic plates taken over time. The nebula's variability is caused by shadows...
McNeil's Nebula is a variable reflection nebula in Orion, discovered by amateur astronomer Jay McNeil on January 23, 2004.
Gyulbudaghian's Nebula is a variable reflection nebula in Cepheus, discovered in 1977 and illuminated by the young star PV Cephei.
A variable reflection nebula in Taurus discovered by John Russell Hind in 1852, illuminated by the young variable star T Tauri and known to change in brightness and extent.
