In this article we are going to look beyond our confined borders of Earth, and explore a world that we aren’t very familiar with, Space. Humans have been intrigued by what is beyond our world for thousands of years. In this article we are exploring recent discoveries in space and what they mean for humans.
One innovation talked about recently, are adding laser cannons to the International Space Station (ISS) to shoot down debris surrounding the Earth. This innovation could be extremely useful for us to help prevent the tragic event of having a meteor or debris crash into the earth. Cannons would also help us get clearer images of the Earth but also protect satellites from crashing into this debris. NASA estimates that there are over 3,000 tons of debris surrounding the Earth, debris can fly up to 22,370 mph which would cause catastrophic damage to anything in its path. The ISS can only withstand debris smaller than 0.4 inches, or about 1 centimetre which can be extremely hard to spot. Japan is also thinking about installing a laser cannon in 2017 to help protect its expensive equipment in space. This idea is revolutionary to both protect expensive satellites and space stations but to also protect Earth. Astronomers might consider having satellites with cannons to protect the Earth from debris crashing into it. Asteroids are becoming more and more concerning and a major threat to humans. As more crash we see the catastrophic damage they can cause and how it affects us. NASA is looking for more insight into their asteroid redirect program, this would help save the planet in the event that an asteroid were to crash on Earth. NASA’s technology is genius, it works by placing a satellite in the trajectory of an asteroid to help redirect its path away from Earth. The work that went into this idea was researching about the catastrophic damage asteroids can cause to our planet. NASA aims to have this project accomplished by 2020 but will require extensive research still. Their project now, creating an algorithm to try to hit objects that fly through the sky.
There is something strange that many people don’t know about, they are called dead galaxies. Dead galaxies can no longer form stars because they are deprived of gas. Scientists have been mind boggled with what actually kills galaxies but now, they think they found out. Scientists believe that galaxies get strangled to death, this is caused by the loss of cold gasses which are vital. Most galaxies experts say are being strangled to death. Dead galaxies have a higher metal content than live galaxies do. A computer estimation of 4 billion years is estimated between live and dead galaxies. “The researchers said the strangulation theory accounts for galaxies up to 100 billion times heavier than the sun, which make up more than 95 percent of all galaxies. For larger galaxies, the evidence was not conclusive for either the strangulation or sudden-removal theories, Peng said(Paragraph 11 Space Galaxy Strangulation).”
Now that we have explored above and beyond Earth, the possibilities for these ideas are endless. They will help protect us in catastrophic events, such as an asteroid crashing on Earth. We still haven’t even touched the surface when exploring space as technology gets better so does our knowledge. Eventually, we will have discovered infinity and beyond.
