Hubble reflection nebula9/1/2023 ![]() A classic example of this is Hubbles Variable Nebula (NGC 2261) in. This is the signature of a ‘reflection nebula’ – this one is known as NGC 1999. Well, the reflection nebula M78 is perhaps the night skys best example of stardust. This bright material in the area pictured here is only visible because of the light from the star it does not emit any visible light of its own. The star is so young that it is still surrounded by a cloud of material left over from its formation. ![]() It appears white owing to its high surface temperature of about 10 000✬ – nearly twice that of the Sun. Astronomers are celebrating NASAs Hubble Space Telescope’s 33rd launch anniversary with an ethereal photo of a nearby star-forming region, NGC 1333. With an apparent magnitude of 7.2 and an apparent size of 12 arcminutes, it can be observed in amateur telescopes. The bright star seen here is V380 Orionis, a young star 3.5 times the mass of our own Sun. The Cocoon Nebula (IC 5146) is a reflection/emission nebula located approximately 2,500 light years away in the constellation Cygnus. ![]() Reflection nebula Hubble/WFPC2 captures the void in 2000. The powerful radiation from a nearby mature star may also have helped to clear the hole. It is a reflection nebula, and shines from the light of the variable star V380 Orionis. In general, such globules are known to be small cocoons of forming stars, but thanks to ESA’s Herschel Space Observatory, which would have been able to see any hints of star formation at infrared wavelengths but did not, along with ground-based observations, it turned out to be a truly empty patch of sky.Īstronomers think that is was formed when jets of gas from some of the young stars in the wider region punctured the sheet of dust and gas that forms the surrounding nebula. When the dark patch was first imaged, it was assumed to be a very cold, dense cloud of gas and dust, so thick as to be totally opaque in visible light, and blocking all light behind it. An image from the European Southern Observatory shows blue light from a newborn star lights up the reflection nebula IC 2631. ![]() While the ‘fog’ is dust and gas lit up by the star, the ‘hole’ really is an empty patch of sky. The NGC 1999 nebula is illuminated by a bright, recently formed star, visible in the Hubble photo just to the left of center. This spooky sight, imaged by the NASA/ESA Hubble Space Telescope, resembles fog lit by a streetlamp swirling around a curiously shaped hole – and there is some truth in that. ![]()
