To better understand where magma gathers in Earth’s crust, researchers studied the Taupo Volcanic Zone of New Zealand, the planet’s most active cluster.
Penitentes – large pointed spikes of ice – are known on Earth and Pluto. Jupiter’s moon Europa might have them, too, according to new research. If they’re there, they could make a future landing on Europa tricky.

Newly-discovered Asteroid 2018 UA made an extremely close approach to Earth on Friday morning. Luckily, the space rock was too small to be dangerous.

NASA is again being encouraged to expand its search for alien life – not just intelligent life – all forms of life, including microbes.
Astrobiology is the scientific study of study of the origin, evolution, distribution and future of life in the universe. The new report from NASEM recommends strategies for NASA to expand its search for life elsewhere. Image via NASA.
Charles Darwin puzzled over why ants come in such wildly different sizes. The question even made him doubt his theory of evolution. New research might explain why.

What’s happening in your dog’s brain when it hears you say squirrel? New research looks at how dog’s brains react to human words.

A waxing gibbous moon appears more than half lighted, but less than full. It rises before sundown and sets somewhere between midnight and dawn. The coming full moon – Hunter’s Moon for the Northern Hemisphere – is October 24.
Not a full moon, but pretty close, from Odilon Simões Corrêa in Brazil.
Binary asteroids – that is, asteroids with moons – aren’t uncommon. More than 300 have been discovered so far. Astronomers found a moon for 2018 EB when it swept closest to Earth on October 7.
