Scientists led by UCLA found that permanently shaded parts of pits on the Moon stay near a constant 17°C while the exposed surface swings between 127°C and −173°C — meaning humanity's first permanent lunar address may be underground.
Voyager 2 is nearly 50 years old, losing about 4 watts of power every year as its plutonium power source fades — and NASA just bought it at least another year of science with an all-at-once power-system swap engineers called the “Big Bang,” performed on a spacecraft with razor-thin power margins and no possibility of physical repair.
A meteorite punched through a bedroom ceiling in Hillsborough, New Jersey, in 2024. Scientists have now found hundreds of different amino acids inside it — and the majority are not known to occur naturally on Earth.
Life on Earth may have begun twice. A Science Advances study found that bacteria and archaea inherited one ancient genetic code but independently evolved the machinery needed to become free-living cells — leading the researchers to describe it as “one origin of the genetic code, but two origins of life.
Voyager 1 is down to two working science instruments, and the fix that just bought its twin, Voyager 2, another year of power is now being tested on a probe NASA says no longer behaves quite like its sibling
