I recently picked up my first DSLR, a Rebel t5, and I've been trying to take a stab at night sky photography, and haven't been getting any good results.
The only lenses I have are the kit lense, and a 50mm f1.8 (the latter is what I used for this project).
My settings were as followed:
>25 second exposure
>f2.8
>1600 iso
Why are all of my shots coming out blurry? I'm about as new to photography as possible, but I did a bit of reading on the subject, and followed it to the T.
As far as focus goes, it's on manual, and this is the clearest shot I could get.
Any suggestions as to how I can get better results?

You missed focus. You can tell because the stars are donuts, rather than pinpoints. The Canon 50 1.8 lacks a hard infinity stop for whatever reason, so you'll have to fidget with the focus manually until you get it.

You forgot to focus.

Alrighty, I tried messing with it, and was only able to get semi-clear shots with the focus all the way to the left, but I'll try some more experimentation.
And for down the road, would you be able to recommend a good wide angle lens that'd do well for night stuff?

Rokinon makes amazing, cheap lenses.

Also, you will get a lot of star trails if you keep your shutter speed at 25 seconds with a 50mm lens. I would suggest going with the kit instead, set at 18mm, with 20 second shutter speed, high ISO (maybe 1600 is enough for you?) and a small aperture. I usually go with a stop or a half stop above max aperture.
Anyway, google and astro threads should have better information for you.

I have the same camera and used the kit lense. I used right around the same setting (and a tripod I assume your using one to) then I took the lense of autofocus and went outside in the daylight and focused it on the farthest thing I could then taped the lense in place so it wouldn't move and lose it. You can try that

focus to infinity using manual focus, you cannot autofocus as the camera cant find anything to focus on
maybe use a smaller aperture as well to get the stars sharper
most importantly, you need a clear sky and somewhere with as little light pollution as possible, so go as far out of whatever city you live in as possible
