A solar eclipse’s appearance is wrapped up in the geometry of the bodies involved.
What’s the most impressive natural phenomenon known to humankind? Probably a solar eclipse! Here’s a brief overview ahead of this summer’s big celestial event.
Venus and Earth share some atmospheric quirks – but how did Venus get so unbearably hot, while Earth is mild and temperate?
Sun safety is not just for beach holidays. Checking the UV index and building small habits into your day can help protect your skin.
The Sun is a complex physical body. It generates incredible amounts of heat and a strong, often tangled, magnetic field.
Astronauts report feeling profoundly awestruck when they go to space, an anthropologist reports. This experience shapes their perspectives even back on Earth.
Astronomers have discovered stellar winds can cause black hole jets to change direction – just like wind on Earth can blow around the water in a fountain.
The answer has to do with the air we breathe and that bright white snowpack, as an atmospheric scientist in Colorado explains.
From Earth spinning on its axis and orbiting the Sun to it precessing like a top, lots of factors affect which stars you can see in the sky.
Solar cycles, sea ice and rising electricity use all play a role. So does an unhealthy surprise that has been quietly hiding a large amount of global warming – until now.
