Astronomers discover giant, rocky 'mega-Earth'
Space.com
It's Wednesday, space fans, and once again have some wild space news to share with you.

First up, astronomers have discovered a "mega-Earth" exoplanet, or planet outside of our solar system, that is a whopping 23 times the mass of our own planet. I wonder what this massive far-off world is really like. Over on the spaceflight side of things, a rocket from private Chinese company LandSpace successfully landed the first stage of its rocket back on Earth. This is only the second time that a Chinese rocket has accomplished such a feat. And speaking of rockets, SpaceX hit a milestone, launching its 100th mission of the year with another Starlink satellite launch. We're only in August, so this is a pretty wild output. 

Check out what's big in space below:

That's it for our space update today!

It was exciting to see the private Chinese rocket's successful touchdown back on Earth. Now that SpaceX isn't the only game in town for landing rocket first stages back on Earth, we can only wonder how the space economy might change. But one thing will stay the same: our curiosity and desire to learn more. The recent discovery of the unbelievably massive "mega-Earth," shows just how much there is left to learn about the universe we live in and the planets orbiting many light-years away. 

We might be about to learn quite a bit more about exoplanets and the universe with the upcoming launch of NASA's Nancy Grace Roman Space Telescope, which is set to lift off in just about a week and a half at NASA's Kennedy Space Center in Florida. This flagship mission will send a brand new and incredibly capable space telescope out into the cosmos to help us broaden our understanding. Space.com staff will be reporting live from this launch, and we can't wait to take you along with us.
