This tool is absolutely remarkable.

This is ultimately the best tool I have yet to see anywhere in the world that best illustrates the vast size and emptiness of our universe. Better yet, it does it with an admirable beauty and elegance. Bravo good Sirs.

Love it!

This is an incredible thing you've put together here. Everyone needs to know about it! I will spread the word.

this is simply amazing. It's a pity that Carl Sagan, Albert Einstein, Edwin Hubble and Isaac Newton aren´t here to see it too, they deserved see it.

This is truly amazing. Thank you.

Is this ever going to update?

This is incredible.

Came across Space Engine by chance. Incredible!

This is a work of art, a masterpiece even. Every astronomy teacher should have this for their classroom.

... it is magic, thx.

What amazes me more than the awesomeness of this program is the lack of "playerbase" and attention it has. Keep up the good work, and do some advertising.

The scales! If you lose a planet and don't remember what it's called, you'll never ever find it again, and that terrifies me. This engine is absolutely amazing, I cannot being to imagine what sort of coding is in place to let me look at a gazillion stars all at once and speeding past at high speed and not melt my computer (much). Keep up the good work. Wanted: Better nebulae, supernovas, a nicer Earth model/texture, comets.

To the creator of Space Engine, thank you so much

It just gets better! Amazing piece of work. Thank you
