      Unfortunately, this is something that happens a lot. A few years ago, I used a space telescope to try and measure the number of X-rays coming from a star. However, it didn’t work as the star was too faint to detect. In astronomy, it’s very rare that you get a second chance to do an experiment like this, as using a space telescope costs a lot of money. So, instead, we focused on writing about why the experiment didn’t work, and publishing that report, so that people in the future wouldn’t make the same mistake we did.
