Wildfire smoke can carry thousands of living microorganisms, like bacteria and fungi, across long distances. Some of them could potentially infect humans. With wildfires on the rise, experts are studying the risk this poses to our health.

Cloud seeding techniques boost clouds’ ability to drop precipitation by releasing particles that attract water, making it easier for water droplets or snowflakes to form.

While a sunset may seem like any other ordinary thing, a number of physical elements had to come together, in just the right way, for you to bear witness to this colorful display.

There are three places in our solar system, beyond Earth, that are good candidates to look for life: Europa, one of Jupiter’s moons, Enceladus, and Titan, two of Saturn’s moons.

The James Webb Space Telescope detects infrared light, which our eyes can’t see. Data image developers bring those observations into the visible light spectrum, where they take on the colors of the rainbow.

Join scientists as they use NASA’s brand new James Webb Space Telescope to peer deep in time to hunt for the first stars and galaxies in our universe, and try to detect the fingerprints of life in the atmospheres of distant exoplanets.

The pyramid was built over 5,000 years ago, even before the pyramids of Egypt and Mesopotamia, a time when archeologists had believed the Amazon was populated only by hunter-gatherers.

Ancient paintings on rock walls feature human figures and animals of today’s rainforest, like deer, tapirs, and jaguars. But they also appear to show animals that went extinct thousands of years ago.

Recent discoveries in archaeology are exploding the myth of the Amazon as a primeval wilderness, revealing traces of ancient civilizations that flourished for centuries, with populations numbering in the millions.

Why does the nose of the football go from pointing upward to rotating downward when most things stay the same orientation when they move through the air? (Think of frisbees, bean bags, even paper airplanes.) The reason is something called "conservation of angular momentum." Discover the physics that explains how a perfect football pass moves through the air.

Along the river Gambia in Senegal, there are more than a thousand stone circles. The people who placed these stones would have observed how the locations of sunrise and sunset varied over the year.

The instrument only requires the observation of the sun’s position to begin making calculations.

A NASA spacecraft named Lucy blasts off from Cape Canaveral on a mission to the Trojans, a group of asteroids over 400 million miles from Earth thought to hold important clues about the origins of our solar system. Just hours before, in Senegal, West Africa, a team of scientists sets out to capture extraordinarily precise observations vital to the success of the Lucy mission.

To keep trains running on schedule, a new feature allows them to reverse direction and change tracks while the driver walks to the other end.

Construction teams use springs to quiet the Elizabeth Line trains as they pass under a concert hall.

Thousands of engineers, technicians and workers race to build Europe’s biggest construction project–London’s new railroad, the Elizabeth Line.

Walter Cunningham was the last surviving member of the Apollo 7 mission. He died at the age of 90, in January of 2023.

From rocket launches, to dazzling new images, and even planetary defense, 2022 was a big year for space discovery.

Panidapu executes complex problems with mental math using the abacus method of calculation, a technique that relies on an ancient tool.

For the first time, lab-made fusion released more energy than it used to start the reaction, a feat that has eluded researchers for decades.
