Your fact check is good, however you could go further in depth about the sources you have used in order to create a stronger argument overall, with many strong sources from places such as BBC, CNN, and NASA, you should flesh it out more and specifically state where they got their evidence from these researchers and what types of studies they did. The topic is a bit difficult to do that however because it borders on myth, however the more detail the better. You did a good job with obtaining the info and you have a great foundation. Good job overall!
