If that Hubble image enticed you, consider installing the Astronomy Pic of the Day app on your phone: https://play.google.com/store/apps/details?id=com.blork.anpod&hl=en
APOD also has a website: https://apod.nasa.gov/apod/astropix.html
The phone app is really awesome. You can set the daily image to be your phone background. The descriptions every day are intriguing - they cover current events in science, rare occurrences, and classics. I was introduced to it by my physics professor, and I've never had a regular phone bg since.
They add a new picture every day but no actual website updates (such as user interface features or modernizing the overall style) have been added since 2000.
Sidenote, I use this app to set these pics as my phone background every day, I recommend it!
I currently use apod which i think is a static live wallpaper. Before that it was muzei, and before that was koi pond which i enjoyed.

Here's a link to link to the app that will change your homescreen to the daily APOD: https://play.google.com/store/apps/details?id=com.blork.anpod
Edit: today's pic doesn't fit as well, but I've been using it for a week and it's been great so far. They need a way to rotate the image for the wallpaper.
I'm a pretty big fan of this one.
Automatic schedulable download, can automatically set wallpaper, AND save to SD, AND it's free with no ads.
I run the APOD app (on Android), so my background changes daily to the current NASA <strong>A</strong>stronomy <strong>P</strong>icture <strong>o</strong>f the <strong>D</strong>ay.
You may already know but amazing pics (like the pillars of creation) get posted to apod everyday. There's also a great android app that can set your phone background with this image each day too.
Idk about IOS, but here's the android link https://play.google.com/store/apps/details?id=com.blork.anpod
It's called Astronomy Picture Of The Day

I use this app so my wallpaper is always NASA's Astronomy Picture of the Day.

This app will update the background every morning to the latest APOD provided by NASA. So this is my current background for Nov 15th

Yesterday's picture was also really cool.

But everyone please don't use this as your background, since there's only 1 picture per day and everyone can't be running around with the exact same new background every day, it wouldn't be as cool.
APOD app in appstore will change your wallpapers daily with the apod feed. It's great.
There's an Android app, too, that can download it each day to your phone and also set it as your background.

I get most of mine from the APOD app.
