3 separate sightings: blue jellyfish and two red globes

I was driving to 24 hr store at about 1am, and I saw a object glide down behind the treeline.  The fact that it disappeared behind the treeline, which was a good 1.5 2 miles away, and that it was still rather large told me it was very big.  The best way I can describe this thing was a glowing blue jellyfish with VERY short lash-like tentacles, or just a brighter glow underneath.  It wasn't bright flashing lights, it was a faint glow.  The closes thing I could find online, was a moon jellyfish, which of course isn't known to fly in the sky... and the view I had was from the side.  It had the swirling center just like the jellyfish, but I only saw two, instead of the clover pattern.
No noises heard, but it was too far away to hear, even if it was.  I drove in that direction it went behind the treeline for another mile, and saw nothing.  After finding nothing online to explain what I saw, I told my mother the next day.  She said she had seen something also the day before.  On the 5th of February in the early morning as well, and she was a globe-like red object in the same area in the sky but a mile further way.  Then a few days later after our conversation, she saw it again, in another area of the sky, closer, and it just hovered for a little bit, then the dog distracted her for a second, so when she looked back up it was gone.
Witness indicates that the date of the sighting is approximate.  PD
