Well it's not like any accomplishments have changed. It just means that they've realized the atmosphere reaches further than they had thought. In the article, it mentions the presence of hydrogen in this part of the atmosphere is so thin so it's very difficult to measure.
Science is always about discovery. Science is almost always going to change as new things get discovered. At one point, it was the belief that the earth was the center of the universe. When they discovered they were wrong, that doesn't mean that science should be abandoned, it just means that advancements in technology allowed for more to be discovered
Well essentaily the word means the area surrounding the planet that contains particles contained in its gravitational pull. Up to a point, we can measure the portions of the atmosphere that can be observed by the presence of moisture/air particles/gravitational pull, but as devices get more sophisticated we can see even fainter measures of the presence of hydrogen (in this instance). We essentially compare that to the composition of dead space, where you're not going to find any such particles presence.
