NASA film traces Artemis 1 rocket's 'Path to the Pad' as mission stack rolls out today
A new NASA video "Path to the Pad: The Rocket" details the awesome might of the SLS megarocket.
Satellites are Tracking Rivers of Garbage Flowing Across the Oceans
There’s an ocean of human-made garbage floating through Earth’s seas. From plastic straws to beverage bottles and food wrappers, the ocean waters are this planet’s fastest-growing junkyard. Some of the plastic gets ground into little beads, and ends up in the food chain, with humans at the top. For that reason, and many others, the European Space Agency is tracking ocean-bound plastics through the auspices of the MARLISAT project. It’s one of 25 efforts created to identify and trace marine litter as it moves through the world’s waterways. The ultimate goal is to help countries reduce ocean litter, particularly plastics.
Lunar Rocks Have Earth's Noble Gases Trapped Inside. More Evidence That the Moon Came From the Earth
Piecing together the history of the Solar System from the traces left behind isn’t easy. Bit by bit, however, we’re working it out. This month, new research examining the composition of lunar meteorites offers compelling evidence that the Moon and the Earth were formed from the same material, perhaps in the aftermath of a cataclysmic collision some 4.5 billion years ago.
Underwater snow on Earth could offer insight into Europa's icy crust
Studying unusual processes of how ice accumulates below ice shelves here on Earth could hold lessons for the exploration and habitability of Jupiter's moon Europa.
NASA's Artemis 1 moon mission will carry 2 water-seeking cubesats
The Lunar IceCube and Lunar Polar Hydrogen Mapper (LunaH-Map) missions will search the moon for water using two different techniques.
Unusual 'revived' pulsars could be the ultimate gravitational wave detector
Astronomers hope to use pulsars scattered around the galaxy as a giant gravitational wave detector. But why do we need them, and how do they work?

NASA will roll out its massive rocket for a flight around the moon earlier than planned.
Extreme physics of 'supercritical' matter may be surprisingly simple
At 'supercriticality,' the difference between the liquid and gas phases of a material seems to disappear. New research finds that this weird tipping point may be simpler than scientists thought.
Giant voids of nothingness may be flinging the universe apart
Dark energy could be caused by pressure from giant voids of nothingness that may be flinging the universe apart.

Hot Stars Blast Away at gas Giants Until Only Their Rocky Cores Remain
In our solar system, we have two types of planets. Small, warm, rocky worlds populate the inner region, while the outer region has cold gas giants. Intuitively this makes a lot of sense. When the solar system was forming, the Sun’s light and heat must have pushed much of the gas toward the outer system, leaving heavier dust and rock to form the inner worlds. Giants could only grow in the cold, dark outer solar system. But we now know our solar system is more the exception than the rule. Many star systems have large gas planets that orbit close to their stars. These hot Jupiters and hot Neptunes are unlike anything in our solar system, and astronomers are keen to understand what they may be like.
