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 ...
NGC 2440 is a planetary nebula, one of many in our galaxy. Its central star, HD 62166, [1] is possibly the hottest known white dwarf, about 400,000°F(200,000°C). The nebula is situated in the constellation Puppis. It was discovered by William Herschel on March 4, 1790. He described it as "a beautiful planetary nebula of a considerable degree ...
NGC 7027 has a rich and highly ionized spectrum caused by its hot central star. [7] The progenitor star of NGC 7027 is believed to have been about 3 to 4 times the mass of the Sun before the nebula was formed. [7] It is possible that the central white dwarf of NGC 7027 has an accretion disk that acts as a source of high temperatures. [24]
A nebula that is visible to the human eye from Earth would appear larger, but no brighter, from close by. [6] The Orion Nebula, the brightest nebula in the sky and occupying an area twice the angular diameter of the full Moon, can be viewed with the naked eye but was missed by early astronomers. [7]
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 ...
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 ...
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 .
Hubble Space Telescope image of the nebula M1-67 and WR 124 at its center. WR 124 is surrounded by an intensely hot nebula formed from the star's extreme stellar wind. [ 9 ] The nebula M1-67 is expanding at a rate of over 150,000 km/h (93,000 mph) and is nearly 6 light-years across, leading to the dynamical age of 20,000 years.
