Google announced that it is taking increasingly longer search queries and making adjustments to SERPs in 2 ways:

2) Longer “Snippets” For Queries More Than 3 Words: For longer, detailed search queries, Google is also providing longer “snippets” that appear underneath the page title to establish more context and relevancy for the searcher. The “snippet” will also bold the query. Here’s the example provided by the Google blog for the search query, “Earth’s rotation axis tilt and distance from the sun”:
