The white dwarf is believed to have a mass approximately 0.7 times the mass of the Sun and is radiating at 7,700 times the Sun's luminosity. [8] NGC 7027 is currently in a short phase of planetary nebula evolution in which molecules in its envelope are being dissociated into their component atoms, and the atoms are being ionized. [25]
Together, the new images showcase the sun’s varied and complex layers. The Polarimetric and Helioseismic Imager took the highest-resolution full views of the sun’s visible surface, or ...
[5] [6] The complex also includes one of the hottest stars discovered within 1 kpc of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45,000 K and a luminosity about 100,000 times that of the Sun. [5] The star is one of the primary sources illuminating the nebula ...
The structure in the nebula is among the most complex ever seen in planetary nebulae. The spectrum of Butterfly Nebula shows that its central star is one of the hottest stars known, with a surface temperature in excess of 250,000 degrees Celsius, implying that the star from which it formed must have been very large.
The image of the Horsehead Nebula captures the iconic nebula in a whole new light. NASA releases 'unprecedented' Horsehead Nebula image captured by James Webb Space Telescope. What to know about ...
The James Webb Space Telescope has revealed colorful new portraits of the iconic Ring Nebula that capture unprecedented details a dying star creates glowing structures. Stunning new images reveal ...
NGC 3132 (also known as the Eight-Burst Nebula, [2] the Southern Ring Nebula, [2] or Caldwell 74) is a bright and extensively studied planetary nebula in the constellation Vela. Its distance from Earth is estimated at 613 pc or 2,000 light-years .
NGC 2244 (also known as Caldwell 50 or the Satellite Cluster) is an open cluster in the Rosette Nebula, which is located in the constellation Monoceros. This cluster has several O-type stars, super hot stars that generate large amounts of radiation and stellar wind. The age of this cluster has been estimated to be less than 5 million years.
