It finally happened! The James Webb Space Telescope is on its way to capturing never-before-seen images of the universe! But now that it’s airborne and unfurled, what are its next steps before it can deliver the goods?

For you, going outside might mean a sunburn if you're out there too long without enough sunscreen, but for some people, any sun exposure can lead to hives and rashes within minutes!

Given that Earth’s magnetic field helps protect its life-sustaining atmosphere, you might think that the stronger a planet’s magnetic field, the better. But as it turns out, some planets’ relationships with their magnetic fields are a...

India has a historic opportunity to power its industrialization with clean energy -- and its energy choices will make or break the world's fight against climate change, says clean energy executive, physicist and author Varun Sivaram....

Planetary alignments: They're the favorite astronomical scenario of kooks, con artists, and Hollywood producers everywhere. But has it ever happened? And what would it do to Earth if it did?

By 2100, the UN estimates that the world's population will grow to just over 11 billion people. Architect Vishaan Chakrabarti wants us to start thinking about how we'll house all these people -- and how new construction can fight climate...

Improving batteries is a tough problem, but it’s also an important one because in many ways the future of our planet also depends on the future of batteries. Luckily, scientists are on the case, figuring out ways to give this essential...
