Here are a couple of photo slides explaining how we can look back in time, when we look up at the stars through a telescope.
Light takes time to travel to Earth, and we measure it in Light Years. So, when we look up at the object – we are actually looking back to when it first started to send its light image towards us – back in time. Crazy concept, isn’t it! 😎
travels at 300,000 km/s. So we see things as they were some time ago. The farther away, the further back in time we are looking. 1 billion LY means looking 1 billion years back in time. So, when we see the stars, we are actually looking at light which was emitted long ago.
You grew the most amazing bright orange carrots in our veggie patch! They were sweet and delicious, even if they had some spectacular shapes…! 🙂
