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 explodes.
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.
Clouds and fog both form when water vapor condenses. So what's the difference between them?
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.
In adults, blood is formed in short, flat bones like the ribs and sternum. This week's viewer question comes from Monica Bustos in Colombia.
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.
And how can you tell what they're dreaming? Researchers want to reveal the secrets of animals dreaming by measuring brainwaves of rats for instance.
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?
Most modern airplanes have curved wingtip devices. How do these "winglets" work, and what benefits do they boast?
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.
This week's Tomorrow Today viewer question comes from Mohammad Billoh Jalloh in Sierra Leone.
This week’s question comes from Amir Halep in Bosnia and Herzegovina.
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 Tomorrow Today viewer question comes from E.S. Cheris
Can lithium-ion batteries be recycled? To do so the output elements need to be separated from each other. But how does that work?
The Tomorrow Today question this week is from Calixto Saldaña in Colombia.
This week's question comes from Jorge Mondragon in Mexico.
This week's viewer's question comes from Esomchukwu Ezeamaku in Nigeria.
Just ask! This week's Tomorrow Day viewer's question comes from Rodrigo in Ecuador.
To achieve an emissions-neutral future, the world will need a lot more photovoltaic systems than we have today. But space is in short supply. So where exactly can we put our solar panels?
This week's DW viewer question comes from Jorge Macea of Colombia.
This week's DW viewer question comes from Noemi Rosa Rebollo Franco from Mexico.
This week's viewer question comes from Rogélio González Labastida in Mexico.
