The Tomorrow Today viewer question this week comes from Salvador Salazar in Venezuela.
Scientists will soon be able to predict solar storms with a special orbiter, set to launch in February. Its job is to track the visible surface of the sun and at the same time map its magnetic field, thereby providing glimpses into the inner life of the sun.
Our sun is a huge ball of electrically charged gas that’s been shining bright for around 4.5 billion years and providing the earth with heat and light. Without it, the rich diversity of life on earth would never have developed.
It isn't only physicists who are fascinated by light. Poets too have been entranced by its powers. Photons have mysterious properties. Perhaps this is why we like to light candles when we're feeling contemplative.
Li-Fi, short for "Light Fidelity" is a wireless technology that uses LED light to share data. It is faster and safer than regular WiFi. And it could soon be put into practice.
Blanketing the Antarctic ice sheet in artificial snow might sound outlandish. But could geoengineering help to counteract runaway climate change? One thing is clear: many of the ideas could be very risky.
Africa’s first climate monitoring station is located on Mount Mugogo in Rwanda. Scientists there monitor levels of various greenhouse gases. They hope their data will help strengthen Africa’s position at international climate negotiations.
In the Gorongosa National Park, young female scientists are cataloguing flora and fauna for a global genetic database. It will enhance our understanding of the diversity of life on earth and the roles different species play.
