What are all the Beacon Special Effects?

In FTL, some beacons have some of the following "environmental/special effects":

Asteroid Field
- periodically an asteroid "attacks" yours and the enemy ships - causing 1 damage
Ion Storm
- half available reactor power (removed randomly if in use)
Too Close to the Sun
- periodically the sun flares causing random fires on yours and the enemy ships
Planetary Defence Cannons
- periodically the planet's weapons fire into space against yours or the enemy ships, maybe both
Ion Event
- random amount of ion damage is applied to several systems on yours and the enemy ships

Not sure of the names for #4 and 5 (both added with Advanced Content).

Does anyone have more specific information about these beacon modifiers (or any I have missed)?

So the full list is

Giant star
- this creates random fires in your and the enemy's ships and, as a secondary effect, will cause hull damage if a system is destroyed
Nebula
- this disrupts the sensors and rebels' speed is halved for the next jump
Plasma storms
- this causes the reactor to run at half efficiency as well as disrupting sensors
Asteroid field
- this causes asteroids to periodically strike your ship and the enemy's ship. If your ship is running with just 1 shield with an unskilled crewmember at the station, it can take damage just from asteroids as the period between asteroids is random. Each asteroid does 1 damage.
Pulsar
- New to the advanced edition. This causes 2 or 3 ion damage to a system (shields if they are up) and 1 ion damage to another system (if shields are down)
Anti-ship battery
- New to the advanced edition. This randomly sends a shield piercing 3 damage shot to your or the enemy ship, hitting a random room and causing a hull breach. While you will be shot at multiple times, the only one that may hit will give you a warning before doing so.
