Firstly,
A question comes in mind that what is a Nebula?
So, A Nebula is a Cloud Of gas and dust in Outer space
Visible in the Night sky either as an Indistinct bright patch or as a dark silhouette against other luminous matter.
Red spider Nebula , Located About 3000 Light years away from us located near the heart of Milky way In the Northwest of constellation Sagittarius . It was Firstly captured By Hubble telescope by Its Wide field and Planetary Camera 2 (WFPC2)
This Nebula as shown in Image contain a White dwarf is the white dot in Its centre its Temperature is Surprisingly incredible 540,000°F . 50 Times Hotter than Our sun which makes it One Of Thr most Hottest Known Stars .It produces a powerful and hot (≈10,000 K) wind blowing with a speed of 2000-4500 kilometers per second, which has generated waves 100 billion kilometres high. The waves themselves move outwards at a slower rate of 300 km/s. These winds are what give this nebula its unique ‘spider’ shape and also contribute to the expansion of the nebula.
This Hubble Space Telescope image was obtained on 12 September 1997 with the Wide Field and Planetary Camera 2 in five different filters. Here, light from sulphur ions is displayed in red, nitrogen ions in orange, and ionised hydrogen (H-alpha) in green, while atomic oxygen is in light blue and ionised oxygen in dark blue.
