Juno results offer tantalizing hints of Jupiter’s secrets

Astronomy Magazine - Thu, 05/25/2017 - 04:00
The first results from Juno’s brush with Jupiter reveal swarms of cyclones, massive ammonia plumes and complex interactions between a turbulent magnetic field and powerful streams of electrons. The findings are published today in Science and Geophysical Research Letters. The Juno team is still sifting through the massive piles of data the probe is sending back from the gas giant. Since arriving last year, the probe has begun to study the composition and internal structure of Jupiter. We&

Mice born from freeze-dried space sperm are doing OK

Astronomy Magazine - Tue, 05/23/2017 - 04:00
Before they were born, these mice were astronauts. Or, rather, the sperm that would go on to deliver half of their genetic material were. For nine months, mouse sperm was kept aboard the International Space Station, freeze-dried to preserve it. Brought back to Earth, the sperm was rehydrated, introduced to an egg and allowed to divide for about 20 days. The resulting mouse pups carry the distinction of having traveled perhaps the farthest distance ever on their way to being born. Sperm In Space

The first true-color images of Saturn taken during Cassini’s close encounter are coming in — and they’re beautiful!

Astronomy Magazine - Mon, 05/15/2017 - 04:00
We’ve already been treated to spectacular black and white closeup images of Saturn, beamed home to Earth by the Cassini spacecraft after it dove between the planet and its rings. Now, we’re getting to see what things look like in true color. Among the first of these images is the one above, processed by Sophia Nasr, an astro-particle physicist working on dark matter. She will begin her PhD studies in physics at UC Irvine in September 2017. (For her full bio, see the end of this post
