Hubble reflection nebula11/16/2023 Therefore what NASA do, is take several photos with different colour filters, and. Like a flashlight beam shining off the wall of a cave, the star is reflecting light off the surface of pitch black clouds of cold gas laced with dust. The problem is, telescopes like Hubble only take photos in black and white. “Hubble studied NGC 6891 as part of efforts to gauge the distances to nebulae, and to learn more about how their structures formed and evolved,” the researchers noted. Caption NASA's Hubble Space Telescope has caught the eerie, wispy tendrils of a dark interstellar cloud being destroyed by the passage of one of the brightest stars in the Pleiades star cluster. “The image also reveals filaments and knots in the nebula’s interior, surrounding the central white dwarf star.”įrom their motions, the astronomers estimated that one of the shells is 4,800 years old while the outer halo is some 28,000 years old, indicating a series of outbursts from the dying star at different times. “The new Hubble image reveals a wealth of structure, including a spherical outer halo that is expanding faster than the inner nebula, and at least two ellipsoidal shells that are orientated differently,” Hubble astronomers said. The object is made up of gas that’s been ionized by a central white dwarf, which stripped electrons from NGC 6891’s hydrogen atoms.Īs the energized electrons revert from their higher-energy state to a lower-energy state by recombining with the hydrogen nuclei, they emit energy in the form of light, causing the nebula’s gas to glow. This image shows the pillars as seen in visible light, capturing the multi-coloured glow of gas clouds, wispy tendrils of dark cosmic dust, and the rust-coloured elephants’ trunks of the nebula’s famous pillars. NGC 6891 was discovered on Septemby the English astronomer Ralph Copeland. The NASA/ESA Hubble Space Telescope has revisited one of its most iconic and popular images: the Eagle Nebula’s Pillars of Creation. NGC 6891 is a bright, asymmetrical planetary nebula in the northern constellation of Delphinus.Īlso known as BD+12 4266, HD 192563 and IRAS 20127+1233, the nebula lies at a distance of 11,784 light-years. Balick, University of Washington / Gladys Kober, NASA & Catholic University of America. NGC 1999 is around 1350 light-years from Earth and lies near to the Orion Nebula, the closest region of massive star formation to Earth. This Hubble image shows NGC 6891, a planetary nebula located 11,784 light-years away in the constellation of Delphinus. This peculiar portrait from the NASA/ESA Hubble Space Telescope showcases NGC 1999, a reflection nebula in the constellation Orion.
