i told my mother about the russian gecko space experiment and she came up with this whole story like “what if they hadn’t restored contact and the geckos landed on a planet with extraterrestrial life. what if the aliens found the capsule and it was their first contact with earth, except they thought the geckos were humankind. they thought geckos were the architects of earth civilization and couldn’t figure out why they displayed no signs of higher intelligence”

LOS ANGELES, CA.- African Cosmos: Stellar Arts is the first major exhibition to explore the historical legacy of African cultural astronomy and its intersection with traditional and contemporary African arts. Documented since the kingdoms of ancient Egypt, for thousands of years Africans throughout the continent have contemplated the celestial firmament and conceived stories about the heavenly bodies. People of many cultures have used such observations to navigate their physical environments and to regulate agricultural and ritual calendars.
African Cosmos considers how the sun, moon, and stars, as well as ephemeral phenomena such as lightning and thunder, serve as sources of philosophical contemplation in the creation of arts from historical times to the present. Far from abstract concepts, African notions of the universe can be intensely personal, placing human beings in relationships with earth and sky. Read more.

Moving fluids around in microgravity can be a challenge. On Earth we experience buoyancy and other gravitational effects that dominate how fluids move. In space, on the other hand, the only options are to move fluids mechanically with pumps or fans or to use capillary action. Even on earth, adhesive forces between a liquid and its solid container can draw fluids in narrow tubes upward against the force of gravity. In microgravity, this capillary flow can be even more effective. But the best way to study and understand this flow regime is to do so in space. The Capillary Channel Flow experiment and similar studies have allowed astronauts on the space station and researchers back on Earth to explore the effects of capillary action on microgravity fluid transport. The results will be used to improve propulsion systems, heat exchangers, and life support systems used in space. (Photo credits: NASA, M. Dreyer et al., and A. Agrawala; submitted by jshoer)

The field of archaeoastronomy is evolving say researchers seeking a closer relationship between astronomy and archaeology
The merging of astronomical techniques with the archaeological study of ancient man-made features in the landscape could prove Neolithic and Bronze Age people were acute astronomical observers, according to researchers.
Dubbed archaeoastronomy, the developing and sometimes maligned field takes a multi-disciplinary approach to exploring a range of theories about the astronomical alignment of standing stones and megalithic structures.
Some of these theories were highlighted recently at the 2014 National Astronomy Meeting in Portsmouth. Read more.

Image description: On Saturday, the Navy christened a new research ship the “Sally Ride” after the first U.S. woman and youngest person in space. It is the fifth current ship named for an astronaut.
Photo from the U.S. Navy
the person doing the christening is dr. tam o’shaughnessy, ride’s partner of 27 yrs. sally ride was not just the first woman and youngest person in space: she was also the first lesbian in space - likely, the first lgbtq person in space.
I know we shared this before but finding out that this ship was christened by Dr. Tam O’Shaughnessy was something that required re-sharing.
Sally Ride was the first american woman in space. the first woman in space was a russian cosmonaut by the name of Valentina Tereshkova.

What if we’re in the farthest reaches of space
What if, literally everywhere else that’s so far away we can’t even detect it, it’s kind of crowded and planets are right up next to each other all the time, clearly visible in every sky, and our entire area of the universe is considered the very edge of nothingness, and that’s why no one comes over here because we are by definition the middle of nowhere
