SUMMARY: The Hubble Space Telescope has revealed an unusual situation where a young, hot star is carving out a cavity in a region of space that was once filled with cold, dense material. The massive star is known as N44F, and its stellar wind is moving nearly 5 times as fast as our Sun's solar wind. It's also ejecting 100 million times more material than the Sun. The fast moving torrent of particles collides with the colder surrounding material, pushes it away, and heats it up. N44F is in the Large Magellanic Cloud, located 130,000 light-years from Earth in the direction of the southern constellation Dorado.
