Why do people have trouble accepting the very true fact that “The Blue Marble” photo of Earth is a composite and therefore (just like every other subsequent “picture” of Earth NASA has ever shown us) not a real photo but computer generated?
Okay, guy. This is the actual Blue Marble photo. It was taken by Apollo 17. It is NOT a composite image. That really is the Earth when viewed…
If a planet could successfully orbit a black hole without being harmed, what would the sky look like from its surface?
I think this question is another example of how badly black holes are misunderstood. Suppose we replaced the Sun with a black hole of the same mass. It…
What is the wind speed on other planets in the solar system?
On Mercury, there is no wind because there is no atmosphere.👇 On Venus, however, there are very strong winds averaging 200 km/h, with peaks reaching 400 km/h👇. On…
What will happen if a person lands on Pluto?
It has a solid surface and we actually, thanks to New Horizons, have mapped a large part of it. So it is actually possible to land there, unlike…
What is below Earth? I don’t mean the center of Earth. I mean like in the universe.
If we assume (for the sake of simplicity) that North is “up” and South is “down”, then asking “What is below Earth?” is essentially the same as asking,…
If the Sun turns into the white dwarf, will it be the end of the Earth?
There is no “if”, there is only “when”. The Earth will most likely be long eaten before our Sun becomes a white dwarf. It’s a damn shame, ain’t…
How does a human body decompose in space?
Unlike decomposition on Earth, governed by bacteria, insects, and a host of environmental factors, the process out there unfolds in an entirely alien way. Forget about putrefaction as…
What would the Sun look like from Pluto?
The Earth is 150 million kilometers from the Sun. Pluto is 6 billion kilometers away, that is, 40 times farther away. Therefore, the Sun would be seen as…
Has Voyager 2 seen anything new since it left the solar system?
Voyager 2 is one of the most amazing space probes ever launched by NASA. It was sent into space way back in 1977, and it’s still going strong…
Jupiter is a gas giant. Could you fly a rocket through Jupiter and out through the other end?
Not a chance. It’s a common misconception that gas giants are made of gas like our atmosphere, since that’s the only gas that the average person interacts with…
