better have some bots and volunteers that regularly wake up for maintenance.
Inb4 you wake up to find:
-Aliens have taken over the ship and taken you in as prisoner for anal butt sex science -Parasitic aliens have taken over and want to plant their eggs in your butt. -Parasitic aliens have taken over and want to plant their eggs in your butt, but you are an engineer. -A bald dude shoots your waifu then puts you back to sleep so you can get revenge.

Wow, what's with the butt sex emphasis? Good ol' facehuggers and chestbursters don't work now?
If your spaceship is fast enough (like 99.999% speed of light) it would be whoosh and there, no books or robots or cryosleep needed. Of course, you still need the blue telephone box for the return trip unless you want to see your great-grandkids or something.
how do they decide that the planet is earth like if that is so far? imagine the disappointment if somehow i can go there and found out its not liveable

They analyzed the reflected spectrum. Basically it's guesswork based on certain amount of light wave reflected from the planet's surface that got detected by the telescope.
Lemme explain how hard is this 'guesswork' would be. Imagine you have a coin placed like, one hundred kilometer from your position. And there's some serious sandstorm happening between you, the observer and the coin; you could only see the glint of the coin between the sandstorm---could you guess what material the coin made of? That's how hard the process to determine if a planet is habitable or not. Fortunately, we have another method to indicate if that planet are habitable or not; the 'Goldilocks Zone' that is a range from a star, calculated from it's size, temperature and state of which a planet (or planets) could host habitable atmosphere, and/or has presence of liquid water.
Basically, we're now zooming on each and any star we can find and then enhanced the focus on that dot to get the information about the orbiting planets, and then calculate the Goldilocks Zone. If there's any planet within that radius, they zoomed in further and try to collect the spectrum data, and so on. It might not be 100% correct, give or take the distance and the obstruction between us and that planet, but it's good enough for now.

Considering as 140 million years ago, the first recognizable mammals had only barely started splitting up into distinct species of rat-like creature, then by the time you wake up, any sort of animal pest stowaway may well have evolved into a sentient being... or, you know, chewed on enough maintenance bot cables to wreck the whole ship, whichever.
I personally always liked Narue no Sekai's solution (even if the author backed himself into it accidentally), which was that, because FTL travel was also both time travel and inter-dimensional travel, post-FTL societies realized that colonizing new planets was essentially never worthwhile.
Instead, they simply used their FTL drives to search for alternate versions (divergent timelines/parallel dimensions) of Earth with no humans already on it, and used those to create an ever-expanding network of already-"terraformed" planets. (This also neatly explained why all the "aliens" looked like humans, were interbreedable, and everyone spoke Japanese.)

Incidentally, this was touched upon in Terry Pratchett and Stephen Baxter's collab sci-fi series, The Long Earth. Slightly different premise whereby interdimensional travel is ridiculously easy, which leads to human colonization of parallel dimensions. However, space exploration, at least after some adjustment, does not stall; in fact, it is facilitated because some parallel Earths no longer existed as a result of some calamity or another, making it possible to exploit the dimensional travel capability to transport objects into space with almost no effort at all. It also provided some justification for why humanity should not be merely content with colonizing parallel worlds: at some point, the Earth may eventually encounter some catastrophe that cannot simply be avoided by shifting to another dimension.
They say that there are some Earth-like planets located about 39 light years away.
Refers to this recent news.39 light years?It's like 39 years away at the speed of light.Light...MiscelleanyIf it was the Kodama, then...How long would that be on the Nozomi?There are three 'speeds' of shinkansen on the Tokaido section (Tokyo>Shin-Osaka (and some that go to Fukuoka also)), the Nozomi ('hope'), Hikari ('light') and Kodama ('echo'); the Nozomi is the one that stops the least, and is thus the fastest; the Kodama stops at every station; and the Hikari stops at more than the Nozomi, but is almost as fast. The vast majority of the timetable is comprised of Nozomi, however.)
