Meteors slamming on the moon reveal groundwater

[ad_1] When NASA astronauts landed on the moon for the first time in 1969, they discovered a world dried up, drained, and devoid of salvific water. The Apollo astronauts, who only stayed a few days, brought a lot of water for their own needs. This finding was therefore disappointing for the fuzzy plans of the … Read more

Disney's "Frozen" inspired a new attempt to find dark matter

[ad_1] Do you want to build a snowball room? Physicists are not often inspired by Disney's musicals to design new experiments, but a team determined to detect dark matter says that's what it did.

SLAC's high-speed "electronic camera" films molecular film in HD

[ad_1] The researchers created the first atomically resolved film of the 1,3-cyclohexadiene (CHD) ring opening reaction with an "electronic camera" called UED. Bottom: The UED electron beam accurately measures the distances between the pairs of atoms of the CHD molecule as the reaction progresses. The distance between each pair is represented by a line of … Read more

The moon loses water when meteorites hit the lunar surface

[ad_1] Meteoroid impacts regularly release flushes of water vapor from the moon, suggesting that tiny amounts of water can hide just under the entire lunar surface, reveals a new study. When the Apollo missions brought lunar rocks to Earth, scientists found evidence that the moon was without water. However, over the last decade, data from … Read more
