As NASA plans to return to the moon, will we be able to see the astronauts on the Moon via a really strong telescope, when they were landed?
Astrophotographer Andrew McCarthy published on his Twitter account an amazing video of the International Space Station (ISS) transiting Moon, over the landing site of Apollo 11, the first moon landing mission. Such an incredible amount of human achievement is represented in just one short video!
NASA Jet Propulsion Laboratory (NASA JPL) has published a great documentary about Casini Spacecraft’s grand voyage (and its finale) around Saturn. Titled “Triumph at Saturn”, the two-part documentary chronicles the story of NASA’s Cassini mission.
Before the invention of the telescope, no one on Earth knew that Saturn had rings until the 1600s. Galileo Galilei discovered them with his telescope in 1610, but he did not know what these were either. Thus they remained a mystery until 1655 when the Dutch astronomer Christiaan Huygens (see notes 1) figured out that they …
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 …
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 …
If we can colonize Mars in the coming decades, will Martian colonists be able to access the Internet?
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
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.
