adobe photoshop - How can I remove text from a background?

I have a background with written text over it. The thing is the image is a .jpeg, and not .psd format, so I don't have access to the layers.

This is the image:

As you can see, the written text ("Space") is quite big.

My question is: are there any effects/anything I can do in order to remove the text and still keep the background? Or at least hide it a little bit more?

Answer

Of course!

Content-aware fill is your best friend in this case.

Just make a selection around the word and go Edit -> Fill -> Content-Aware.

This usually does a pretty good job:

Then you can either go back over it multiple times (maybe in smaller sections) with Content-Aware fill to clean it up, or you can play with the Spot Healing Brush Tool (J) or the Clone Stamp Tool (s).
