Solar Eclipse Calculator: a nice tool by NASA

Today I learned that there’s a solar eclipse calculator on the NASA website. Its official name is JavaScript Solar Eclipse Explorer (JSEX). Using this solar eclipse calculator, you can compute the local circumstances for every solar eclipse visible from a city for any century from -1499 to 3000 (1500 BCE to 3000 CE).

When did we first realize that Saturn had rings

Before the invention of the telescope, no one on Earth knew that Saturn had rings until the 1600s.

Thus they remained a mystery until 1655 when the Dutch astronomer Christiaan Huygens (see notes 1) figured out that they …

How Mars Died? The Death Of Mars

Mars is now a cold and extremely arid desert that is constantly bombarded with deadly solar radiation. It has a very thin atmosphere (it’s really thin, it is practically almost a vacuum) and no liquid water. But that was not always the case. Billions of years ago, Mars had liquid water on its surface. It …

A small telescope beyond Saturn could solve mysteries of the universe better than giant telescopes near Earth

Dozens of space-based telescopes operate near-Earth and provide incredible images of the universe. But imagine a telescope far away in the outer solar system, 10 or even 100 times farther from the Sun than Earth. The ability to look back at our solar system or peer into the darkness of the distant cosmos would make …

Why Earth and Venus followed different paths

Earth is the only planet we know contains life. Is our planet special? Scientists over the years have mulled over what factors are essential for, or beneficial to, life. The answers will help us identify other potentially inhabited planets elsewhere in the galaxy. Antony Burnham, Australian National University and Hugh O’Neill, Australian National University

Moon samples returned from Chang’e-5 tell of recent volcanism

Change-5 represents China’s first mission to return moon samples to Earth, hence marks a major step forward for China’s lunar exploration program. Now, recent analysis suggests that the Moon samples returned from Chang’e-5 tell of recent volcanism.
