Predictions for January 1, 2050:
No space probe has passed Voyager 1, nor will any craft be traveling on an escape trajectory that will pass Voyager 1 before 2100.
The atmospheres of a variety of exoplanets will have been characterized. None will be in the kind of obvious life-generated disequilibrium that Earth's is in (e.g. oxygen and methane co-existing at significant levels globally), although a few will show tantalizing hints of disequilibrium.
The life expectancy record of Jeanne Calment (122.5 years) still stands. That one is looking like a weird fluke - nobody's even reached 118 in the 21st century.
No element with an atomic number above 124 will have been synthesized. My most likely guess is we'll be somewhere from 120-122. 119 and 120 may well be discovered in the fairly near future but very little will happen after that because of the extremely short lifetimes and low fusion cross-sections above 120.
We still won't know what dark matter is.
