2023年3月14日 · The rare sight of a Wolf-Rayet star – among the most luminous, most massive, and most briefly detectable stars known – was one of the first observations made by NASA’s James Webb Space Telescope in June 2022. Webb shows the star, WR 124, in unprecedented detail with its powerful infrared instruments.

2023年3月14日 · Wolf-Rayet stars are known to be efficient dust producers, and the Mid-Infrared Instrument (MIRI) on NASA’s James Webb Space Telescope shows this to great effect. Cooler cosmic dust glows at the longer mid-infrared wavelengths, displaying the …

2023年3月14日 · The luminous, hot star Wolf-Rayet 124 (WR 124) is prominent at the centre of the NASA/ESA/CSA James Webb Space Telescope’s composite image combining near-infrared and mid-infrared wavelengths of light.

2023年3月14日 · The luminous, hot star Wolf-Rayet 124 (WR 124) is prominent at the center of the James Webb Space Telescope’s composite image combining near-infrared and mid-infrared wavelengths of light. The star displays the characteristic diffraction spikes of Webb’s Near-Infrared Camera (NIRCam), caused by the physical structure of the telescope itself.

WR 124 is a Wolf–Rayet star in the constellation of Sagitta surrounded by a ring nebula of expelled material known as M1-67. [9] . It is one of the fastest runaway stars in the Milky Way with a radial velocity around 200 km/s. It was discovered by Paul W. Merrill in 1938, identified as a high-velocity Wolf–Rayet star. [10] .

2023年3月14日 · Wolf-Rayet stars are known to be efficient dust producers, and the Mid-Infrared Instrument (MIRI) on the NASA/ESA/CSA James Webb Space Telescope shows this to great effect. Cooler cosmic dust glows at the longer mid-infrared wavelengths, displaying the structure of WR 124’s nebula.

2023年3月18日 · Explanation: Driven by powerful stellar winds, expanding shrouds of gas and dust frame hot, luminous star Wolf-Rayet 124 in this sharp infrared view. The eye-catching 6-spike star pattern is characteristic of stellar images made with the 18 hexagonal mirrors of the James Webb Space Telescope.

2023年3月14日 · As one of its first observations in 2022, the NASA/ESA/CSA James Webb Space Telescope captured the Wolf-Rayet star WR 124 in unprecedented detail. A distinctive halo of gas and dust frames the star and glows in the infrared light detected by Webb, displaying knotty structure and a history of episodic ejections.

A 'prelude to a supernova' is how NASA describes this stunning new James Webb Space Telecope image of Wolf-Rayet Star WR 124. Travel 15,000 light years in th...

2023年3月15日 · 在詹姆斯·韦伯太空望远镜的合成图像中，发光、炽热的恒星沃尔夫-拉叶星WR 124位于中心，该图像结合了来自韦伯近红外相机和中红外仪器的近红外和中红外波长的光。 沃尔夫-拉叶星是已知的最明亮、质量最大、可探测时间最短的恒星之一，这颗罕见的恒星是NASA詹姆斯·韦伯太空望远镜于2022年6月首次观测到的恒星之一。 韦伯用其强大的红外仪器以前所未有的细节展示了这颗名为WR 124的恒星。 这颗恒星位于1.5万光年外的人马座。 大质量恒星在它们 …
