SciFi and Fantasy Book Club discussion

Looking to find a book from about 20 years ago , well known author as I remember . A "trail" that indicates star ship travel is detected at a vast distance(obviously occurring many many years ago) , a small group is put together to travel to the area , knowing that as time passes different at near light speed , their 6 year mission will cover thousands of years . They do take a detour along the way , and end up returning about 10,000 years from when they left .

Can you describe the book cover? Was it a paperback or hardcover? Can you remember any names? Did the small group leave from Earth or a colony or what?

Here's an article on far-future sci-fi...

Could it be by Michael McCollum?

It was a hard cover , I seem the remember a ship on the cover that was round more than long , could be wrong on that . The group left from Earth , and I remember about halfway through the trip the trails from their view seemed to stop , making it a mission to something that no longer existed . Bit a of downbeat book as I remember .

Thank you , wasn't on that list or the suggested replies . I may be on the hunt for a very elusive book .

I think maybe I found it... Starfarers by Poul Anderson

Bingo !!!! Thanks , I'm going to put that at the top of my re-read list .

I'm glad I could help.

I wish there was an app for computer or tablet , that would keep a list of your favorite authors , then download a dated list of their works. I have a old fashion notebook back from when I used to collect book , had somewhere around 2500 until I sold/donated .
