An image from the European Southern Observatory shows blue light from a newborn star lights up the reflection nebula IC 2631. 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. The bright star seen here is V380 Orionis, a young star 3.5 times the mass of our own Sun. The powerful radiation from a nearby mature star may also have helped to clear the hole. Reflection nebulae such as IRAS 00044+6521 are clouds of interstellar dust. It is approximately 2,700 light-years from Earth. We were interested to learn whether such. Image credit: NASA / ESA / Hubble / Judy Schmidt, IRAS 00044+6521, also known as IRCO 1971, GN 00.04.4 or PP 1, is an irregular reflection nebula in the constellation Cassiopeia. ![]() These fast-moving jets, which form as gas collects around newly forming stars and last for only about 100,000 years, are known to play a role in star formation, the researchers said. Astronomers are celebrating NASAs Hubble Space Telescope’s 33rd launch anniversary with an ethereal photo of a nearby star-forming region, NGC 1333. 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. A box in the ground-based infrared image of M78 at left shows the location of Hubble’s close-up infrared view on the right. Hubble observed G035.20-0.74 as part of a program examining jets of blasted into space by massive protostars. 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. While the ‘fog’ is dust and gas lit up by the star, the ‘hole’ really is an empty patch of sky. 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. ![]()
