Eos is a crescent-shaped molecular cloud about 300 light-years from our solar system. It resides on the edge of the Local Bubble, a huge “cavity” in space filled with gas, which is about 1,000 light-years across.
Our star resides in the Local Hot Bubble (LHB). Now a team of astronomers has mapped the bubble, revealing the presence of a mysterious tunnel pointing towards the constellation Centaurus.
The bubble is 10,000 times wider than the Milky Way and located 820 million light-years from our own galaxy. The astronomers have called their bubble Ho’oleilana – meaning “sent murmurs of awakening”.
