Webb Measures Distance to Farthest Fast Radio Burst, Suggesting Origin
First discovered in 2007, fast radio bursts are enigmatic, millisecond-long flashes of radio emission from the distant universe. Their origin remains uncertain, particularly since most are seen once and never again. Astronomers using NASA’s James Webb Space Telescope have pinpointed the host galaxy of the most distant fast radio burst (FRB) seen to date.
Mars’s Most Mysterious Cloud Might Be Defying Textbook Cloud Physics
It may not be as obvious, but just like Earth, Mars has seasons. And every day of every summer, an 1,800 kilometer long thin white cloud appears to the west of Arsia Mons, a 20 kilometer high extinct shield volcano. At least for a few hours, before it dissipates until it reappears the next morning.
Two looks at the sky today. NASA tells it like this: First discovered in 2007, fast radio bursts are enigmatic, millisecond-long flashes of radio emission from the distant universe. Universe Today comes at it from another side: It may not be as obvious, but just like Earth, Mars has seasons. Put them next to each other and you see how much of what we know about the universe comes from patient looking, one picture at a time. Read both and see which one makes you look up tonight.
