NGC 6886 is a planetary nebula in the constellation Sagitta. It was discovered by Ralph Copeland on September 17, 1884. [3] It is 4.6 ± 1.0 kiloparsec (15.0 ± 3.3 kly) distant from Earth, and is composed of a hot central post-AGB star that has 55% of the Sun's mass yet 2700 ± 850 its luminosity, with a surface temperature of 142,000 K.

Aug 29, 2016 · Photographs taken with the Hubble Space Telescope explain NGC 6886's multipart listing by revealing two "wings'' extending an additional 2 arc-seconds on either side of the nebula's circular inner shell.

Jan 10, 2011 · Astronomers have used the NASA/ESA Hubble Space Telescope to image the tiny planetary nebula NGC 6886. These celestial objects signal the final death throes of mid-sized stars (up to about eight times the mass of the Sun); when such a star exhausts its supply of hydrogen fuel, the outer layers begin to expand and cool, which creates an envelope ...

NGC 6886 is a Planetary Nebula in the Sagitta constellation. NGC 6886 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year.

Aug 20, 2022 · NGC 6886 (Sge): This little nebula is the minute, absolutely tiny NGC 6886 in Sagitta. It marks the NP-most vertex of a nice little not-quite-right triangle, and lies in a busy Milky Way field.

Located in a dense part of the Milky Way in far eastern Sagitta 3 1/3 degrees west of Gamma Sge (and more or less between the Dumbbell Nebula and IC 4997), the compact planetary nebula NGC 6886, though "quite bright" [Curtis], remains something of a mystery thanks to a very uncertain distance and a hidden central star.

Nov 12, 2024 · Astronomers have used the NASA/European Space Agency Hubble Space Telescope to image the tiny planetary nebula NGC 6886. These celestial objects signal the final death throes of mid-sized stars (up to about eight times the mass of the Sun).

Jan 1, 1995 · The relatively young, high-excitation planetary nebula (PN) NGC 6886 shows a remarkable variety of lines from both high- and low-excitation stages, i.e., from N 0 to N 4+, and as a result it provides unique opportunities for detailed studies of physical processes, using a theroetical model.
