April Flowers for redOrbit.com - Your Universe Online NASA has released a hauntingly beautiful composite image showing a superbubble in the Large Magellanic Cloud (LMC). The LMC is a small satellite galaxy of the Milky Way located about 160,000 light years from Earth. A superbubble is a cavity, filled with 106 Kelvin gas blown into the interstellar medium by multiple supernovae and stellar winds, hundreds of light years across. These cavities are carved out of the surrounding gas by the...

ESO's Very Large Telescope captured this striking view of the nebula around the star cluster NGC 1929 within the Large Magellanic Cloud, a satellite galaxy of our own Milky Way. A colossal example of what astronomers call a superbubble dominates this stellar nursery. It is being carved by the winds from bright young stars and the shockwaves from supernova explosions. The Large Magellanic Cloud is a small neighboring galaxy to the Milky Way. It contains many regions where clouds of gas and...

A study of supernova remnants "“ material blown out into space during death throes of giant stars "“ has shown that a bubble of gas enveloping our Solar System is being shoved backwards by the debris of another, more recent, supernova. Over the last few million years, several stars have exploded within the Milky Way and they have left behind bubbles of expanding, hot gas that radiate low-energy X-rays. The Solar System sits within one of these shells, known as the "Local Hot...

NRAO -- Astronomers using the National Science Foundation's Robert C. Byrd Green Bank Telescope (GBT) have discovered a huge "superbubble" of hydrogen gas rising nearly 10,000 light-years above the plane of our Milky Way Galaxy. They believe the gas may be driven by supernova explosions and the intense stellar winds from an unseen cluster of young stars in one of our Galaxy's spiral arms. "This giant gas bubble contains about a million times more mass than the Sun and the energy powering its...

Gemini Observatory -- A storm of billowing clouds blown by the winds from massive stars, and set aglow by their light, is the focus of a striking image released today by Gemini Observatory. Known as the N44 superbubble complex, this cloudy tempest is dominated by a vast bubble about 325 by 250 light-years across. A cluster of massive stars inside the cavern has cleared away gas to form a distinctive mouth-shaped hollow shell. While astronomers do not agree on exactly how this bubble has...
