Hi Mike,

A short wave receiver is fine for Jupiter and the Sun. A long wire will do the trick a yagi will be too large for low frequency 0~ 30 Mhz.
Long wire antennas are simple to make the formula is 468/frequency.
You can hear Jupiter's lightning storms around 15 Mhz. spectrum where the antennas are much smaller. I usually work in the high end of the radio around the 21 cm hydrogen band.
Still you will be surprised what you can hear with just a short wave radio.
Meteor pings are interesting you can sometime get FM radio stations for a few seconds as the radio waves bounce of the meteor's trail.
