Happy Wednesday, space fans

As we count down to tomorrow's Crew-13 launch, we are diving deep into some strange science. Starting off, astronomers have taken what is the equivalent of an "ultrasound" of a planetary system, and they've found twins orbiting their parent star. Speaking of strange other worlds, scientists have discovered a lava world. But it's not just any lava world. It has an atmosphere, and is actually the coldest lava world ever spotted with an atmosphere, expanding our understanding of these extreme planets. And if you find yourself looking up at the night sky tonight thinking about all of the weird worlds out there, you might get lucky and see a meteor shower as the Draconids are upon us once again. 

Check out what's big in space below:

And that's it for our space update today!

As usual, there is no shortage of weird science and strange spaceflight news. From cold lava worlds to alien planet ultrasounds, the truth is really stranger then fiction some days. But the fun never stops, and right now, we are just one day away from Crew-13. NASA's Crew-13 mission will launch to the International Space Station aboard a SpaceX Crew Dragon capsule that will take off atop a Falcon 9 rocket. This continued collaboration between government and industry will send four astronauts to the space station where they will conduct research and continue progress in orbit.

The astronauts onboard will include NASA astronauts Jessica Watkins and Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov. And we'll have the full scoop as Space.com will be reporting from the launch site in Cape Canaveral, Florida, so stay tuned for updates. Coming up soon, as we find ourselves on the cusp of October (somehow), we will be celebrating World Space Week. This will be a great opportunity to explore the cutting edge of spaceflight and space science as we look to the future of what's possible on the final frontier. To follow closely along and stay up to date with all things space, you can now get Space.com right in the palm of your hand with our new app available now on iOS and Android.
