No, you have to jump through them to see what's there. Here's some probing advice:

ALWAYS ALWAYS ALWAYS bookmark both sides of every wormhole. If you jump into wormhole space and forget to bookmark the spot and warp off then you'll be scanning down another exit, and depending on the hole there may be a lot of locations to scan through to find your way out again.

If you jump into wormhole that has a gate camp DO NOT MOVE. You have a 30 second timer while invis. Just target the wormhole and start spamming the jump button.

ALWAYS have a cloak and preferably be in a cov ops. If you want to do any scanning in a system first cloak, then warp to a planet at 100km, start moving, uncloak, pop 5 probes out, recloak, and then scan.

After jumping into a wormhole hit the directional scan at max range 360 degrees. This will usually tell you if there is a POS (unless the system is really big).

After you jump in note the name (Jxxxxxx) and go here and search for it: http://evemaps.dotlan.net/system/J205004 That will tell you activity in the past few days.

Never jump to a newly probed wormhole at 0m. Jump there cloaked at 100km and look for a gate camp first.
