Bally (University of Colorado at Boulder), and DSS Processing: Gladys Kober (NASA/Catholic University of America) Typically the outflow of jets like this would only be visible as it collided with surrounding material, creating bright shock waves that vanish as they cool. This makes it particularly useful to researchers because its outflow remains visible under the ionizing radiation of nearby stars. The gas of the jet has been ionized until it glows by the radiation of a nearby star, 42 Orionis. The star powers a pulsing jet of plasma that stretches over two light-years through space, bending to the north in this image. The jet (the orange object at the bottom center of the image) is being emitted by the young star Parengo 2042, which is embedded in a disk of debris that could give rise to planets. The gas in the jet is ionized by the radiation of a nearby star, 42 Orionis.Ī jet from a newly formed star flares into the shining depths of reflection nebula NGC 1977 in this Hubble image. It is responsible for powering a jet of plasma that stretches 2 light-years across. The star is shrouded in a disk of debris in which planets may form in the future. The young star Parengo 2042 (P2042) was detected with NASA’s Hubble Space Telescope. In 2021, astronomers reported the discovery of a swift stellar jet from a newly formed star in NGC 1977. Two of them have clearly resolved central sources that are associated with disks of radii between 50 and 70 astronomical units. Six of the seven proplyds show tails pointing away from the star. The ultraviolet radiation from 42 Orionis is eroding the protoplanetary disks, while the star’s strong stellar winds are carving the shapes of the gas into cometary tails. The discovery of the proplyds in NGC 1977 was the first time that astronomers found an instance where a B-type star was causing the photoevaporation of a proplyd.

These proto-planetary disks (proplyds) are being photoevaporated by 42 Orionis. 2016 discovered proplyds in NGC 1977 with the Hubble Space Telescope. All seven are within 1 parsec of 42 Orionis and are pointing in the direction of the star, which is the common ionizing source. Six were discovered with the Hubble Space Telescope and one with the infrared Spitzer Space Telescope in 2016. Seven of these objects have been confirmed so far. The Running Man Nebula contains the largest number of known proplyds outside the Orion Nebula. Almost 180 of these objects have been detected in the Orion Nebula, the nearest region of massive star formation to the Sun. Proplyds are photoevaporating protoplanetary disks found around very young stars. The proplyd had a bent protostellar jet and a possible ionization front facing 42 Orionis. Observations with the Hubble Space Telescope in 2012 revealed a candidate proplyd (ionized protoplanetary disk) in the nebula NGC 1977. Processing CCDStack, Photoshop CC, PixInsight.

NGC 1973 and NGC 1975 were discovered by German astronomer Heinrich Louis d’Arrest, director of the Østervold Observatory at the University in Copenhagen, in 18. Herschel catalogued the object as “H V 30” with a note “42 Orionis and neb.” It was discovered by the German-born British astronomer William Herschel in 1786. NGC 1977 is the brightest and largest nebula in Sh2-279. The designation is sometimes used for the whole nebula complex. The Running Man Nebula is commonly associated with the New General Catalogue designation NGC 1977, which refers to the reflection nebulosity around the star 42 Orionis (c Orionis) in the southeastern part of Sh2-279. The star-forming region Sh2-279 consists of the reflection nebulae NGC 1973, NGC 1975, and NGC 1977, and the open cluster NGC 1981.
