A very inspirational video created by Michael Marantz, titled “Earth: The Pale Blue Dot”, which contains readings from Carl Sagan’s “Pale Blue Dot“.Continue reading Earth: The Pale Blue Dot by Michael Marantz
By studying lunar craters, scientists have discovered that the asteroid impacts became more frequent about 290 million years ago. So was just a matter of time for dinosaurs to becoming extinct.Continue reading Dinosaurs were already doomed as the frequency of Asteroid Impacts increased 290 million years ago
The speed of light is the Universal speed limit – nothing can travel faster than light. In the vacuum (commonly denoted c), its exact value is 299,792,458 meters per second (around 186,000 miles per second). In other words, if you could travel at the speed of light, you could go around the Earth 7.5 times in one second.Continue reading Speed of Light – See how torturously slow it is
Scientists from the China National Space Administration (CNSA) has confirmed that the seedlings taken to the far side of the moon with
Margaret Hamilton is not only one of the first software developers, but she also literally created the term “Software Engineering” to describe her work. The code she wrote successfully put humans on the moon for the first time.Continue reading Margaret Hamilton – her code got humans on the moon
In 1964, Russian astrophysicist Nikolai Kardashev (born April 25, 1932) defined three levels of civilizations, based on the order of magnitude of power available to them:Continue reading There is most probably no Kardashev Type-III civilization in the Universe. Here’s why
Musicians from Zambia (Africa) protest the destruction of the environment and the wildlife with the song titled “
Launched by NASA on September 5, 1977, to study the outer solar system, the Voyager 1 is the furthest human-made object from Earth. As of January 10, 2019, the space probe is more than 13,491,481,615 miles (21,712,434,988 km) away from our home planet. It is also moving away at a speed of 38,026.77 mph (61,198.15 km/h) relative to the Sun. But, thanks to NASA’s Deep Space Network (DSN) Notes 1, we can still communicate with it (also with its sister, Voyager 2). But how far can Voyager 1 go before we lose communication?
The video published by the Primal Space channel below looks at how we communicate with Voyager and when it will eventually stop receiving our signals.Continue reading Watch: How far can Voyager 1 go before we lose contact?
We only see one side of the moon, because it is tidally locked to the planet Earth (tidal locking the situation when an object’s orbital period matches its rotational period). What if the Earth was tidally locked to the Sun?Continue reading What if the Earth was tidally locked to the Sun?
