The observable universe stretches roughly 93 billion light-years across and holds an estimated one billion trillion stars. Yet the universe's expansion tells a stranger story: dark energy is accelerating galaxies away from one another at rates that exceed the speed of light, shrinking our cosmological horizon: The boundary beyond which no signal can ever reach us, to about 16 billion light-years. Beyond that threshold, the cosmos becomes permanently unknowable. And within all of that immensity, as Carl Sagan so movingly reminded us, we live on a pale blue dot. A single, fragile mote among countless heavenly bodies, most of which have never been named, let alone explored. That vastness isn't cause for despair, it's an invitation.

Verdict
The clearest difference is update cadence: Skylob at every 3 weeks against SAMPE Journal's every 13 months. SAMPE Journal's advantage is iOS requirement (11.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
