Hot gas may be carrying energy out of the Tarantula Nebula
Astronomers found several possible ways energy leaves the Tarantula Nebula, a region filled with young stars.
The nebula, also called 30 Doradus, lies about 160,000 light-years away in the Large Magellanic Cloud.
Its massive young stars send powerful winds into surrounding gas, which was expected to heat up and produce more X-rays than astronomers observe.
Up to half of the hot gas may escape through gaps in surrounding structures, taking energy with it.
Hot gas may also cool as it mixes with colder material, while simulations point to heat conduction as another possible process.
These processes could explain the missing X-ray glow and show how energy from young stars moves through and out of a stellar nursery.
Researchers say hot gas may be carrying energy out of the Tarantula Nebula.
Up to half of the nebula’s hot gas may escape through openings in surrounding gas and dust structures.
The energy in escaping gas no longer contributes to the X-ray glow measured inside the nebula.
The team also suggests that hot gas mixing with colder material may cool and reduce the amount of gas that emits X-rays.
The research was led by Jennifer Rodriguez of The Ohio State University and published in the Astrophysical Journal.
