Explosion of life on Earth linked to heavy metal act at planet’s centre

At the centre of the Earth, a giant sphere of solid iron is slowly swelling. This is the inner core and scientists have recently uncovered intriguing evidence that suggests its birth half a billion years ago may have played a key role in the evolution of life on Earth. At that time, our planet’s magnetic …

One of Webb Space Telescope’s Primary Instruments Ready To See Cosmos in Over 2,000 Infrared Colors

This animation shows the path light will follow as it hits the primary James Webb Space Telescope (JWST) mirror, and is reflected to the secondary, and then in through the aft optics assembly where the tertiary and fine steering mirrors are. The light is then reflected and split and directed to the science instruments by …

A tiny spacecraft could pave the way for a station between Earth and the moon

The miniscule satellite, called a CubeSat, is about the size of a microwave oven and weighs just 55 pounds (25 kilograms), but it will be the first to test out a unique, elliptical lunar orbit. The CubeSat will act as a pathfinder for Gateway, an orbiting lunar outpost that will serve as a way station …
