Duel Particle Beams in Herbig Haro 24


This might look like a double-bladed lightsaber, but these two cosmic jets actually beam outward from a newborn star in a galaxy near you. Constructed from Hubble Space Telescope image data, the stunning scene spans about half a light-year across Herbig-Haro 24 (HH 24), some 1,300 light-years away in the stellar nurseries of the Orion B molecular cloud complex. Hidden from direct view, HH 24's central protostar is surrounded by cold dust and gas flattened into a rotating accretion disk. As material from the disk falls toward the young stellar object it heats up. Opposing jets are blasted out along the system's rotation axis. Cutting through the region's interstellar matter, the narrow, energetic jets produce a series of glowing shock fronts along their path.

In 1901 Colombia minted special coins for use in leper colonies. Following the first leprosy congress in Berlin in 1897, the nation minted coins in five values for use in three colonies. The point was to keep leprosy from being spread, by preventing money touched by lepers from getting circulated throughout the population.

The Philippines followed suit in 1913, followed by Japan and Malaysia. The United States produced special coins for a colony in the Panama Canal Zone. The coins were produced to protect healthy people, but in 1938 Gordon Alexander Ryrie, director of Malaysia’s Sungei Buloh Settlement, proved that the disease can’t spread by such casual contact. His colony burned the notes it had printed.

Newly Discovered Origins of an Old Song: Kumbaya

For a long time, people thought the song “Kumbaya” was composed by a white evangelical in 1936. But there is a recording from 1926 of a man singing it. Specifically, a Gullah Geechee man named H. Wylie. The chorus means “come by here” which in the Gullah Geechee creole language sounds like “cum-bay-ya.” With time that pronounciation slowly morphed in the kumbaya most of us recognize today.

Gullah is a unique creole language spoken along the Sea Islands and adjacent coastal areas of South Carolina and Georgia. Gullah language began as a simplified form of communication among people of different languages including European slave traders, slave owners and diverse African ethnic groups, taking words and vocabulary from English and a variety of African languages – a creole. Gullah Geechee language is the only distinctly African creole language in the United States. And now Kumbaya has been recognized as Georgia’s first state historical song by Georgia’s state legislature.
