NGC 7129 is a celestial object visible during summer nights in the northern hemisphere (circumpolar visible) in the central-western part of the Cepheus constellation, approximately 4 degrees away from...

NGC 7129 is a reflection nebula primarily, where the originating open cluster is supposed to be younger than 1 Mio. years. Additionally at some shock fronts the hot stars trigger faint Hα emission overlaying the blue reflection. The surrounding gas and dust cloud also forms various dark nebulae (LDN 1181, 1183, ..).

2021年10月15日 · NGC 7129 is a reflection nebula located in the constellation Cepheus. Located 3,300 light years away, NGC 7129 is a young open cluster of newborn stars. Many of the stars within the cluster are less than 1 million years old, which is very young when you consider many of these stars will live to be

Explanation: This wide-field telescopic image looks toward the constellation Cepheus and an intriguing visual pairing of dusty reflection nebula NGC 7129 (right) and open star cluster NGC 7142. The two appear separated by only half a degree on the sky, but they actually lie at quite different distances.

These bright young stars are found in a rosebud-shaped (and rose-colored) nebulosity known as NGC 7129. The star cluster and its associated nebula are located at a distance of 3300 light-years in the constellation Cepheus. A recent census of the …

2021年11月6日 · NGC 7129 is a striking reflection nebula in Cepheus that is situated 9.9 deg above the Galactic plane at a distance of about 3300 lys, Its color derives from scattering by gas and dust of the prodigious starlight produced in its central regions by a young cluster of at least 130 stars with ages less than 2 million years.
