SpaceX tweeted this photo today showing its Dragon capsule berthed to the International Space Station. Earth is beautiful every day, and you can't beat a view like this.
NASA has lots of views just like it. Along with their beauty, they can also tell us something about how we are changing our planet. The space agency celebrates Earth Month, not just Earth Day, and you can see some more amazing Earth-from-space views on its Earth Month page.
Happy Earth Day!
