What happens when an astrophysical jet moving at enormous speeds plows into the gas and dust around it? Some of that matter gets dragged along for the ride — and according to this author, this process could create the two different types of jets that we see.
Looking for something fun to consider today? Try this on for size: what happens to life on Earth if a gamma-ray burst points at us from within our own galaxy?
As we push spacecraft to the edges of our solar system and beyond, it gets harder and harder to navigate them from Earth. But what if spacecraft could steer themselves, using observations of pulsars? Read on to find out how!
What causes the giant radio and gamma-ray bubbles inflated from our galactic center? This paper provides another good argument for star formation as the culprit.
I’m going to go ahead and give away the punchline: the answer to this post’s title is, “If your source is within 8 degrees of the Moon, quite probably.” — at least according to this paper’s authors. Read on to find out why!
