Trip to Down high by Eoin McCaughley
Although I already knew that when a star explodes it leaves behind a supernova and a black hole or a neutron star, but when a star like our sun dies it just cools down very fast and collapses into a white dwarf star. I have learnt some new facts from our trip to Down High.
I learnt that the Andromeda Galaxy is going to collide with our galaxy in the next 3 to 5 billion years and the large galaxy left behind might be called milkromeda and our solar system might not get affected. We also learnt that the Andromeda has quite a lot of infrared places where stars are born. I also learnt that you can see through liquid by using infrared light and I also learnt about what things it takes to get a rocket into space - you need fuel, heat and oxygen to get rockets into space.
I learnt that the Hubble space telescope can only see one pixel when looking at Pluto, the dwarf planet. Another fact I learnt is at least every planet in the solar system has an atmosphere although the atmosphere on Venus heats the planet up to 500 degrees Celsius, even though it the second planet from the sun. Jupiter has the largest atmosphere in the solar system and I also learnt that there’s a planet nine out there somewhere.
However, the most interesting thing I enjoyed was that some of the moons in the solar system might be liveable for people as they have liquid oceans under its surface. The second most liveable moon in the solar system is called Titan. On Titan the rain is methane and so is its lakes, I enjoyed the trip to the Down High.
