Great shot! Reminds of the old 80’s HBO Feature Presentation intro

If the impact is big enough, the entire surface of the earth will be lava, so there won't even be cockroaches or bacteria.

This cool NASA animation shows the most recent idea of how it happened. https://youtu.be/kRlhlCWplqk

Most of the impactor (estimated to have been approximately the size of Mars) was incorporated into the Earth, while debris from the collision, partly from the Earth and partly from the impactor, coalesced to form the Moon.

So cockroaches will rule the Earth then?

What happened to the planet that slammed into Earth? I assume the Moon formed from the debris from that collision.

>wasn't the Moon formed by a huge asteroid slamming into Earth
The moon was formed by a planet slamming into the Earth. There are no longer any rogue planets waiting to smack into the Earth.
Whether a smaller interstellar object would be detected before impact depends on its size and direction of approach. Such objects travel faster relative to the Earth than local asteroids, shortening to lead time between detection and impact. In the unlikely event the object approached from the sunward direction we might never see it coming.
BTW, the Earth has been struck by meteoroids of interstellar origin as recently as 2014. Our atmosphere affords us a great deal of protection from most of what's out there, interstellar or not.
>How could we stop it though?
For the foreseeable future, we couldn't.

Humans aren't advanced enough as a species to stop something like that

That’s beautiful. I just finished rewatching interstellar and getting some crazy black hole vibes from the photo.
Love the star trails!

You sir are an inspiration to me. I can not in words, begin to thank you for this incredibly fascinating phenomenon. Incredibly inspiring. I truly wish I could shake your hand sir. Consider yourself a hero in my world. May the universe bless you, your family, your crew and all you come in contact with. This is by far, one of the greatest words I’ve ever read in all my life.

Do you ever find the radiation interfering with consumer electronics?
