Winners of 2021 Nobel Prize in Physics built mathematics of climate modeling, making predictions of global warming and modern weather forecasting possible

Modern climate and weather models can predict what the weather will be next week and what the climate may be in 100 years. They would not exist without Syukuro Manabe, Klaus Hasselmann and Giorgio Parisi.

James Webb Space Telescope: An astronomer on the team explains how to send a giant telescope to space – and why

The largest orbital telescope ever made will allow astronomers to study the atmospheres of alien planets, learn about how stars form in the Milky Way and peer into the farthest reaches of the universe.

Is space infinite? We asked 5 experts

The universe has a finite age — 13.8 billion years to be exact. So if it had a beginning, why is it so difficult to say for sure whether it will have an end?
Scientists have been studying lunar samples brought back from Apollo missions to understand the geologic history of the Moon. NASA

Moon lacked a magnetic field for nearly all its history – new research resolves mystery sparked by rocks brought back on Apollo

Without a magnetic field, the Moon’s surface is exposed to solar wind. These could have been depositing resources like water and potential rocket fuel on the Moon’s surface for billions of years.

Why does gravity pull us down and not up?

Gravity is something every person on Earth intuitively understands: It is what keeps you on the ground. But how come gravity pulls down, rather than pushes up? Einstein came up with the answer.

Tour de France: How many calories will the winner burn?

Riders in the 2021 Tour de France will ride more than 2,100 miles (3,400 km) over the 21 flat and mountainous stages of the race. And they will burn an incredible amount of energy while doing so.
