The permission for that entry is shown at the far left field of each line. Look at the permissions field carefully. The first part, the single letter or dash, signifies what the named entry is. The leftmost grouping of three shows the owner's permission. In your home directory, you are the owner.
Writing includes the ability to delete.
The second set of three shows the group's permission. Skyshell is the group that most of SkyPoint's users belong to. The second set of three therefore applies to anyone in the skyshell group, which is an awful lot of people. That means that anyone in that group could read or copy the file, but could not delete, change, or run it. Here, they are the same as for the group.
