Hundred-year storms? That's how long they last on Saturn      (via sciencedaily.com) 

Megastorms regularly appear on Saturn, marring the relatively bland surface before disappearing. But radio observations show that the storms have long-lasting effects deeper in the atmosphere, in particular in the distribution of ammonia. Using NRAO's Very Large Array, astronomers see such impacts from storms that happened hundreds of years ago. The findings will help explain the differences between storms on the gas giants Saturn and Jupiter.

Possible seasonal climate patterns on early Mars      (via sciencedaily.com)     Original source 

New observations of mud cracks made by the Curiosity Rover show that high-frequency, wet-dry cycling occurred in early Martian surface environments, indicating that the red planet may have once seen seasonal weather patterns or even flash floods.

Physicists demonstrate how sound can be transmitted through vacuum      (via sciencedaily.com)     Original source 

A classic movie was once promoted with the punchline: 'In space, no one can hear you scream'. Physicists have now demonstrated, to the contrary, that in certain situations sound can be transmitted strongly across a vacuum region!

Gravitational arcs in 'El Gordo' galaxy cluster      (via sciencedaily.com) 

A new image of the galaxy cluster known as 'El Gordo' is revealing distant and dusty objects never seen before, and providing a bounty of fresh science. The infrared image displays a variety of unusual, distorted background galaxies that were only hinted at in previous Hubble Space Telescope images.

Using gemstones' unique characteristics to uncover ancient trade routes      (via sciencedaily.com)     Original source 

Gems' unique elemental composition and atomic orientation act as a fingerprint, enabling researchers to uncover the stones' past, and with it, historical trade routes. Scientists now employ three modern spectroscopic techniques to rapidly analyze gems found in the Arabian-Nubian Shield and compare them with similar gems from around the world. They have identified elements that influence gems' color, differentiated stones found within and outside the region, and distinguished natural from synthetic.

Sun 'umbrella' tethered to asteroid might help mitigate climate change      (via sciencedaily.com)     Original source 

Earth is rapidly warming and scientists are developing a variety of approaches to reduce the effects of climate change. An astronomer has proposed a novel approach -- a solar shield to reduce the amount of sunlight hitting Earth, combined with a tethered, captured asteroid as a counterweight. Engineering studies using this approach could start now to create a workable design that could mitigate climate change within decades.

Astronomers shed new light on formation of mysterious fast radio bursts      (via sciencedaily.com) 

International team reports on a radio pulsar phase of a Galactic magnetar that emitted a fast radio burst in 2020; observations suggest unique origins for 'bursts' and 'pulses,' which adds to FRB formation theory.

Listen to a star 'twinkle'      (via sciencedaily.com)     Original source 

Many people know that stars appear to twinkle because our atmosphere bends starlight as it travels to Earth. But stars also have an innate 'twinkle' -- caused by rippling waves of gas on their surfaces -- that is imperceptible to current Earth-bound telescopes. In a new study, researchers developed the first 3D simulations of energy rippling from a massive star's core to its outer surface. Using these new models, the researchers determined, for the first time, how much stars should innately twinkle.

Webb snaps highly detailed infrared image of actively forming stars      (via sciencedaily.com)     Original source 

Young stars are rambunctious! NASA's James Webb Space Telescope has captured the 'antics' of a pair of actively forming young stars, known as Herbig-Haro 46/47, in high-resolution near-infrared light. To find them, trace the bright pink and red diffraction spikes until you hit the center: The stars are within the orange-white splotch. They are buried deeply in a disk of gas and dust that feeds their growth as they continue to gain mass. The disk is not visible, but its shadow can be seen in the two dark, conical regions surrounding the central stars.

Family trees from the European Neolithic      (via sciencedaily.com)     Original source 

The Neolithic burial site of Gurgy 'les Noisats' in France revealed two unprecedentedly large family trees which allowed a Franco-German team to explore the social organization of the 6,700-year-old community. Based on multiple lines of evidence, the team describes a close kin group which practiced monogamy and female exogamy, and experienced generally stable times.
