NASA needs your help to identify cities at night images

Since the “space-age” has started in the early 1960s, astronauts have taken more than 1.8 million photographs of the Earth from orbit, and about one-third of them (approximately 600,000) have been taken at night. But they don’t always know what they are looking at. You can help, announced NASA – the space agency needs your […]

Krakatoa from space

On August 26-27, 1883, a small island in the Indian Ocean obliterated itself in one of the most notorious volcanic eruptions in history.

Giant weta is endemic to New Zealand and is an example of island gigantism: which is a biological phenomenon leading to a larger size than their mainland […]

Pale Blue Dot

The farthest spacecraft from Earth, NASA’s Voyager 1 Notes 1 probe took a photo of planet Earth in 1990, from a record distance of about 6 billion kilometers (3.7 billion miles, 40 AU Notes 2) from Earth. The photo is known as the Pale Blue Dot. In the photograph, Earth is shown as a fraction […]
