Can you blow my mind with a space fact?
Here’s one that blew my mind not that long ago when I read about it. I wrote about this before. As an amateur astronomer who has been looking…
What would happen if a Jupiter-sized iron planet hit the Sun at 100 kilometers per second?
First of all it could NOT hit the sun at 100 km/s – the MINIMUM speed at which it could hit the sun would be 617 km/s. If…
If the universe is so big, why haven’t we encountered an advanced alien civilization yet?
Look at it like this. If there were intelligent life out there, how would they know about us? The only way is by monitoring radio transmissions. The first…
Could the North Star possibly be a sun with its own solar system?
Whoa! You’re underestimating the north star! POLARIS – Dhruva for us in India – is a multiple star system containing a total of 5 stars. Polaris appears to us as…
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…
