The color of smoke depends on what’s burning, and how it’s being burned. Smoke can be black, white, or grey – and chemicals can even make it colorful. This week’s viewer question comes from Harfiz Abu B. from Ghana.
1816 became known in Europe as the "Year Without a Summer". The year before, Indonesia’s Mount Tambora had erupted in a huge explosion. Ash from the volcano darkened skies around the globe, resulting in failed harvests, famine and epidemics.
When does a volcano explode? And when does it erupt more gently, without an explosion? It's a question volcanologists are seeking to answer. No one can look inside a volcanic vent. But laboratory experiments can show how magma erupts and explod
Contrary to what photos taken by Apollo astronauts suggest, stars are indeed visible from the moon. But they appear differently to what they do here on Earth.
Solar panels convert sunlight into electrical energy, and have turned into a key contributor for making energy supplies more sustainable. But how do they actually work?
Fog coalesces when water vapor condenses. The resulting droplets reflect light and obscure vision. This week's viewer question comes from Dobrila B. from Bosnia and Herzegovina.
Some 7,000 light-years from Earth are gigantic cosmic columns of dust and gas. Because new stars are coalescing there, the formation is known as the Pillars of Creation.
Condensation trails are linear artificial clouds that form from the exhaust of airplanes. Do they have an effect on the climate? This week's viewer question comes from Al Ben M. in Panama.
Auroras can have very different shapes and colors. They occur when solar particles interact with the Earth's magnetic field. This week's viewer question comes from Rafael Nuñez in Finland.
Men are ambitious, women good at multitasking, right? But how are these various skills reflected in the brain? This week's question for Tomorrow Today comes from Timothy Rintaugu from Kenya.
Love originates in the brain, just like other emotions do. It sometimes makes our hormones go crazy and we sometimes can feel like we're on a roller coaster ride. But what exactly is going on inside us when we’re in love?
Solar flares are one of the most spectacular events on the sun's surface. These eruptions can significantly impact the functioning of technology on Earth — and our health.This week's Tomorrow Today viewer's question comes from Rodrigo in Ecuado
So far no tropical cyclone has made it across the equator. It doesn't mean that it is not possible. In recent decades cyclones were rather moving away from the equator.
The moon appears in the sky in different places at different times. Every day, it comes up around 50 minutes later than it did the day before. But it always rises in the east and sets in the west.
The European's Space Agency's longest trip ever is underway. The six billion kilometer, eight-year-long flight is meant to find out if Jupiter's moons, Ganymede, Callisto and Europa are capable of sustaining human life.
This week's viewer question comes from Rodrigo Moncayo in Ecuador. He wants to know whether it's true that water drains in opposite directions in the northern and southern hemispheres.
