Our galaxy is on a collision course….

While most of the galaxies around us are speeding away from us, two galaxies in our local group are actually getting closer to us and will collide with us in the future. The first is the Andromeda Galaxy, another large galaxy like us, the second is the Triangulum Galaxy a smaller galaxy. But don’t worry its not for another 6 billion years.

Supernovas were originally called Stella Novas and we know of 6 different ways they can form.

There are 6 different ways a sun can go super nova, and its not just 1) Boom 2) Booom 3)Boooom etc. The causes can range from a sun being too fat to two failed stars being too close to each other, or just having too much iron in their diet and for all we know their may be more ways.

Something hit earth to form the moon, it probably also gave us life.

After our planets formation we where just a hot rock, slowly getting water from asteroids and cosmic gas. But how did life form? It is believed that life is formed when many many different materials / chemicals are introduced. We also believe that our moon was formed after something big collided with our planet and the material thrown into orbit formed the moon. A current theory thinks that whatever hit us, to form the moon, also brought with it, enough new chemicals / materials that Earth could soon start making life.

Space Startup wants to use dangerous substance for competitive edge.

All of the major players in space travel do not use Mercury in their propulsion engines. Even in tiny amounts, Mercury can do a lot of damage to the human brain, and so using it for space travel is both a risk to those working with it and to whomever comes into contact with any trace amounts left behind in the exhaust.

Space Startup Apollos Fusion is apparently intended on using it as it performs better than the alternatives which has environmentalists and current space companies nervous.

What is Redshift and Blueshift?

Read any amount of space articles and you will come across the term Redshift. So what does it mean.

Well things in space are not static, they are moving and so when the light that a distant star emits reaches us, that sun of it has either moved away or towards us in the time it took for the light to get to us. This is very common in our universe as many of our neighboring galaxies are moving away from us.

So what happens to the light? Well if the object is moving away from us the light it emits stretches, and because light is on a spectrum, the stretched light shifts towards the red end of the spectrum. Conversely if the object is getting closer to us the light compresses and shifts towards the blue end of the spectrum. Which is how we knew that the Andromeda Galaxy was moving towards us (read above) as the light coming off it was Blueshifting.

Why do I write these articles

Reading about Space has become a new hobby for me, as a massive Sci-Fi fan reading about our discoveries is just as exciting as reading about massive space fleets battling it out in space. However as an amateur writer I wanted to contribute with my words but quickly realized it will be a long long long time before I have the nous to write a great space article. My solution was to put to ‘paper’ what I spend my waking hours doing; telling people about the exciting space news I had just read, which is why I landed on this format. I wanted to provide a TLDR that people at my level could read, feel ‘in the know’ but still be able to go read the original authors hard work if the particular story interested them.
