Unveiling the Center of Our Milky Way Galaxy

We captured an extremely crisp infrared image of the center of our Milky Way galaxy. Spanning more than 600 light-years, this panorama reveals details within the dense swirls of gas and dust in high resolution, opening the door to future research into how massive stars are forming and what’s feeding the supermassive black hole at our galaxy’s core.
Among the features coming into focus are the jutting curves of the Arches Cluster containing the densest concentration of stars in our galaxy, as well as the Quintuplet Cluster with a stars a million times brighter than our Sun. Our galaxy’s black hole takes shape with a glimpse of the fiery-looking ring of gas surrounding it.
The new view was made by the world’s largest airborne telescope, the Stratospheric Observatory for Infrared Astronomy, or SOFIA.

Hügelkultur (German, meaning “hill culture” or “mound culture”) is the garden concept of building raised beds over decaying wood piles. Decayed timbers become porous and retain moisture while releasing nutrients into the soil that, in turn, promote root growth in plant materials. As the logs decay, they expand and contract, creating air pockets that assist in aerating the soil, allowing roots to easily penetrate the soil. This decaying environment creates a beneficial home to earthworms. As the worms burrow into the soil, they loosen the soil and deposit nutrient-rich worm castings, beneficial to plants. An earthworm can produce its weight in castings on a daily basis.
The best decayed wood for a Hügelkultur, according to A Growing Culture, comes from alders, applewood, cottonwood, poplar, maple and birch. Use wood products that have been in the process of decay for about a year (using green, or fresh, wood products will rob the soil of necessary nitrogen). Some wood products, like cedar and black walnut, should be avoided because they produce organisms that negatively effect plant growth.

This looks a bit weird, but you can create private spaces in your garden. Natural walls are always better than stonewalls in your garden!
As soon as I own a house I’m doing this.
reblogging for future reference. This is fascinating.
