Measuring the Moon's nano dust is no small matter      (via sciencedaily.com) 

Researchers are now measuring tinier moon dust particles than ever before, a step toward more precisely explaining the Moon's apparent color and brightness. This in turn might help improve tracking of weather patterns and other phenomena by satellite cameras that use the Moon as a calibration source.

Scientists discover a new auroral feature on Jupiter      (via sciencedaily.com) 

Astronomers have detected new faint aurora features, characterized by ring-like emissions, which expand rapidly over time. Scientists determined that charged particles coming from the edge of Jupiter's massive magnetosphere triggered these auroral emissions.

The case of the cloudy filters: Solving the mystery of the degrading sunlight detectors      (via sciencedaily.com)     Original source 

Sun-facing satellites monitor the Sun's ultraviolet (UV) light to give us advance warning of solar storms. But over the course of just a year or two, the metal filters in the detectors mysteriously lose their ability to transmit UV light. Now, scientists have found the first evidence indicating that carbonization is not the problem.

Powerful stratospheric winds measured on Jupiter      (via sciencedaily.com) 

Astronomers have now directly measured winds in Jupiter's middle atmosphere. By analyzing the aftermath of a comet collision from the 1990s, the researchers have revealed incredibly powerful winds, with speeds of up to 1450 kilometers an hour, near Jupiter's poles. They could represent a 'unique meteorological beast in our Solar System'.

Jupiter's Great Red Spot feeds on smaller storms      (via sciencedaily.com) 

The stormy, centuries-old maelstrom of Jupiter's Great Red Spot was shaken but not destroyed by a series of anticyclones that crashed into it over the past few years, according to a new study.

Engineers propose solar-powered lunar ark as 'modern global insurance policy'      (via sciencedaily.com) 

Researchers are taking scientific inspiration from an unlikely source: the biblical tale of Noah's Ark. Rather than two of every animal, however, his solar-powered ark on the moon would store cryogenically frozen seed, spore, sperm and egg samples from 6.7 million Earth species. The proposed structure would be built within the moon's enormous, underground lava tubes, which have been untouched for billions of years.

Source of hazardous high-energy particles located in the Sun      (via sciencedaily.com) 

In the new study, researchers analyzed the composition of solar energetic particles heading towards Earth, and found they had the same 'fingerprint' as plasma located low in the Sun's corona, close to the middle region of the Sun's atmosphere, the chromosphere.

Comet makes a pit stop near Jupiter's asteroids      (via sciencedaily.com) 

After traveling several billion miles toward the Sun, a wayward young comet-like object orbiting among the giant planets has found a temporary parking place along the way. The object has settled near a family of captured ancient asteroids, called Trojans, that are orbiting the Sun alongside Jupiter. This is the first time a comet-like object has been spotted near the Trojan population.

Apollo rock samples capture key moments in the Moon's early history      (via sciencedaily.com) 

Volcanic rock samples collected during NASA's Apollo missions bear the isotopic signature of key events in the early evolution of the Moon, a new analysis found. Those events include the formation of the Moon's iron core, as well as the crystallization of the lunar magma ocean -- the sea of molten rock thought to have covered the Moon for around 100 million years after the it formed.
