Astronomers have taken a step towards understanding how the Moon might have formed out of a giant collision between the early Earth and another massive object 4.5 billion years ago.

An international team of scientists has identified a problem with the growing interest in extractable resources on the moon: there aren't enough of them to go around. With no international policies or agreements to decide 'who gets what from where,' scientists believe tensions, overcrowding, and quick exhaustion of resources to be one possible future for moon mining projects.

The first mining experiments conducted in space could pave the way for new technologies to help humans explore and establish settlements on distant worlds, a study suggests.

The high-pressure mineral Donwilhelmsite, recently discovered in the lunar meteorite Oued Awlitis 001 from Apollo missions, is important for understanding the inner structure of Earth.

The mineral olivine, thought to be a major component inside all planetary bodies, holds secrets about the early formation of the solar system, and a team of researchers has a new way to study it remotely.

New work reveals the likely original locations of Saturn and Jupiter. These findings refine our understanding of the forces that determined our Solar System's unusual architecture, including the ejection of an additional planet between Saturn and Uranus, ensuring that only small, rocky planets, like Earth, formed inward of Jupiter.

Hidden pockets of water could be much more common on the surface of the moon than scientists once suspected, according to new research.

     (via sciencedaily.com) 

NASA's Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places.

An international team of scientists recently measured the spectrum of the atmosphere of a rare hot Neptune exoplanet, whose discovery by NASA's Transiting Exoplanet Survey Satellite (TESS) was announced just last month.

     (via sciencedaily.com) 

Astronomers have crunched data from NASA's TESS and Spitzer space telescopes to portray for the first time the atmosphere of a highly unusual kind of exoplanet dubbed a 'hot Neptune.'

A long discussed theory about the local magnetic spots of the moon suggests that they are the result of magnetization processes caused by impacts of massive bodies on the moon surface. A new study now shows that the Moon must have had an internal core dynamo in the past.

In 2015, the New Horizons space probe discovered spectacular snowcapped mountains on Pluto, which are strikingly similar to mountains on Earth. Such a landscape had never before been observed elsewhere in the Solar System. Scientists determined that the methane snow could only appear at the peaks of Pluto's mountains high enough to reach this enriched zone that the air contains enough methane for it to condense.

A growing body of research suggests the planet Venus may have had an Earth-like environment billions of years ago, with water and a thin atmosphere.

New international research into the Moon provides scientists with insights as to how and why its crust is magnetized, essentially 'debunking' one of the previous longstanding theories.

Researchers create a new 3D model that could explain the formation of a hexagon storm on Saturn -- a hurricane about 20,000 miles in diameter.

Venus might not be a sweltering, waterless hellscape today, if Jupiter hadn't altered its orbit around the sun, according to new research.

Geoscientists have found the largest extraterrestrial diamonds ever discovered - a few tenths of a millimeter in size nevertheless - inside meteorites. Together with an international team of researchers, they have now been able to prove that these diamonds formed in the early period of our solar system when minor planets collided together or with large asteroids. These new data disprove the theory that they originated deep inside planets - similar to diamonds formed on Earth - at least the size of Mercury.

In the coming years and decades, various nations want to explore the moon, and plan to send astronauts there again for this purpose. But on our inhospitable satellite, space radiation poses a significant risk. Scientists report for the first time on time-resolved measurements of the radiation on the moon. The measurements show an equivalent dose rate of about 60 microsieverts per hour. In comparison, on a long-haul flight from Frankfurt to New York, it is about 5 to 10 times lower, and on the ground well over 200 times lower.

Researchers have shaken up a once accepted timeline for cataclysmic events in the early solar system. Geological and geochemical records indicate that the Earth-Moon system experienced a period of frequent and cataclysmic impacts from asteroids and other bodies. It was thought that this period had a relatively sudden onset, but the researchers have found evidence that this bombardment period may have started much earlier, and decreased in intensity over time.

Researchers has found that some of the oldest terrain on Venus, known as tesserae, have layering that seems consistent with volcanic activity. The finding could provide insights into the enigmatic planet's geological history.
