It was the location that was important. Like Mac, I piled on some vegetation in the middle of the float, too. Used under cover, they worked well during both fall and spring, but in the spring you have more rats traveling so production should be higher then. I do feel using them in places that afford protection for the muskrats from raptors work best.
Planetary Nebula are the outer layers of a star that are lost when the star changes from a red giant to a white dwarf. A star is a luminous globe of gas producing its own heat and light by nuclear reactions (nuclear fusion). They are born from nebulae and consist mostly of hydrogen and helium gas.
A Giant New Star is Born in the Milky Way. As best they can determine, astronomers think that the very first stars in the universe were monsters, 100 times as massive as the Sun, which burned through their nuclear fuel in just a few million years before exploding in the cataclysmic events known as supernovas.
