Hubble Finds Vast Reservoir of Gas Near Milky Way

AI Thread Summary
Astronomers have discovered a vast stream of gas near the Milky Way, significantly larger than previously estimated, which could extend the galaxy's ability to form new stars for billions of years. This finding addresses concerns about the Milky Way's gas shortage, suggesting that it has a more robust fuel supply than thought. The study has received praise from experts for its surprising results and implications for our understanding of galactic evolution. The research highlights the importance of the Magellanic Stream in providing essential materials for star formation. This discovery reshapes expectations for the Milky Way's future starmaking capabilities.

The Milky Way may have found a solution to its gas shortage. Astronomers had calculated that our home galaxy possesses only enough fuel to forge new stars for just a few billion more years. But scientists have now discovered that a long stream of gas falling into the Milky Way is four times as massive as previously thought and could power our galaxy's starmaking career for a long time to come.

"It's a very beautiful study with surprising results," says a leading astronomer who was not part of the project.

Full story is at ScienceNOW and includes an outstanding image of the Magellanic Stream.

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
