A spiral galaxy like the Milky Way contains stars, stellar remnants, and a diffuse interstellar medium (ISM) of gas and dust. The interstellar medium consists of 10â4 to 106 particles per cm3 and is typically composed of roughly 70% hydrogen by mass, with most of the remaining gas consisting of helium.
What do cardinals eat for food? Cardinals eat a variety of wild and feeder seeds, including sunflower, safflower and most other seeds in basic wild bird seed mixes. In warm seasons they also eat insects anâ¦d worms and feed their babies mainly an insectivore diet.
Unlike migratory birds, red cardinals do not go away for winter. Instead, they stay to sing songs during frosty cold winter days, painting the scenery with their beautiful feathers. They represent the warmth, the life and energy. A cardinal may symbolize the fire of life that burns within our souls, even in the darkest and coldest times.
