Earth's Systems
- Physics
Scientists Say: Neutron
Neutrons are one of the main building blocks of atoms and have no electric charge.

Cosmic timeline: What’s happened since the Big Bang
Energy, mass and the cosmos' structure evolved a lot over the past 13.82 billion years — much of it within just the first second.

One 2022 tsunami may have been as tall as the Statue of Liberty
A massive volcanic eruption in the South Pacific, earlier this year, appears to have triggered one tsunami that was initially 90 meters (nearly 300 feet) tall.
- Climate
Heat waves appear more life-threatening than scientists once thought
This is bad news as a warming planet leads to growing numbers of excessive heat waves — and millions more people facing potentially deadly temperatures.
- Physics
Scientists used lasers to make ‘smoke rings’ of light
Physicists had a bright idea: Make light into swirling, ring-shaped vortices, similar to smoke rings or bubble rings.

Uplifting Antarctic shores point to accelerating loss of glaciers
It appears the Pine Island and “Doomsday” Thwaites glaciers are losing ice — and shrinking faster — than at any time in the past 5,500 years.
- Chemistry
Let’s learn about diamond
Diamond is born under extreme heat and pressure inside Earth and elsewhere in the universe.
- Earth
Scientists Say: Fault
A fault is a crack in Earth’s crust where pieces of rock scrape past each other.
- Earth
Tiny gemstones show when Earth’s crust first started moving
Chemical hints observed in zircons suggest when the important process of plate tectonics first took off.
- Physics
Gravitational waves ‘kicked’ a newborn black hole across space
Two black holes merged into one, and then sped off at around 5 million kilometers (3.1 million miles) per hour.
- Earth
Scientists Say: Atmosphere
An atmosphere is an envelope of gas around a planet, dwarf planet or moon.
