Super is a sequel series to Dragon Ball and Dragon Ball Z produced by Toei Animation, and isn't directly based on any source material. The original manga/comic ended its run in the 90s.
Dragon Ball Super available for legal streaming on funimation.com and crunchyroll.com.
The latest season, The Future Trunks Saga, just ended last week.
What the next arc will be, I don't think they mentioned yet.
