Photo by @eduardo_del_alamo A gentoo penguin – the fastest underwater swimmer of all penguins – flees for its life as a leopard seal bursts out of the water. Eduardo was expecting it. He had spotted the penguin, resting on a fragment of broken ice. But he had also seen the leopard seal patrolling off the Antarctic Peninsula coast, close to the gentoo’s colony on Cuverville Island. As Eduardo’s inflatable headed towards the penguin, the seal passed directly beneath the boat. Moments later, it surged out of the water, mouth open. The penguin made it off the ice, but the seal now seemed to turn the hunt into a game. Leopard seals are formidable predators. Females can be 3.5 metres (11½ feet) long and weigh more than 500 kilograms (1,100 pounds), males slightly less. Their slender bodies are built for speed, with wide jaws bearing long canines and sharply pointed molars. They hunt almost anything, from fish to the pups of other seal species. And they also play with their prey, as in this instance, with the leopard seal pursuing the penguin for more than 15 minutes before finally catching and eating it. #Nature #Antarctica #Penguin #Underwater #LeopardSeal https://www.instagram.com/p/B2byRJ3Az0S/?igshid=dbpubgbi19se
On this day, 15 September 1954, Veterans of the Abraham Lincoln Brigade - American volunteers in the Spanish civil war - were brought before the Subversive Activities Control Board to respond to attempts to classify them as a subversive organisation. This is some of what Crawford Morgan (pictured), one of its members, said: “Being a Negro, and all of the stuff that I have had to take in this country, I had a pretty good idea of what fascism was and I didn’t want no part of it. I got a chance to fight it there with bullets and I went there and fought it with bullets. If I get a chance to fight it with bullets again, I will fight it with bullets again… I felt that if we didn’t lick Franco and stop fascism there, it would spread over lots of the world. And it is bad enough for white people to live under fascism, those of the white people that like freedom and democracy. But Negroes couldn’t live under it. They would be wiped out… From the time I arrived in Spain I felt like a human being, like a man. People didn’t look at me with hatred in their eyes because I was black, and I wasn’t refused this or refused that because I was black. I was treated like all the rest of the people were treated, and when you have been in the world for quite a long time and have been treated worse than people treat their dogs, it is quite a nice feeling to go someplace and feel like a human being.”
In this podcast, we tell the story of the Spanish civil war: https://workingclasshistory.com/2018/07/29/spanish-civil-war-podcast/https://www.facebook.com/workingclasshistory/photos/a.296224173896073/1211313902387091/?type=3
Lake Resia in South Tyrol, Italy. The lake is famous for its steeple of a submerged 14th-century church, which can be reached on foot when the water freezes. A legend says that during winter one can still hear church bells ring.
The gif above shows data taken by an experimental weather satellite of Hurricane Dorian on September 3, 2019. TEMPEST-D, a NASA CubeSat, reveals rain bands in four layers of the storm by taking the data in four different radio frequencies. The multiple vertical layers show where the most warm, wet air within the hurricane is rising high into the atmosphere. Pink, red and yellow show the areas of heaviest rainfall, while the least intense areas of rainfall are in green and blue.
How does an Earth satellite the size of a cereal box help NASA monitor storms?
The goal of the TEMPEST-D (Temporal Experiment for Storms and Tropical Systems Demonstration) mission is to demonstrate the performance of a CubeSat designed to study precipitation events on a global scale.
If TEMPEST-D can successfully track storms like Dorian, the technology demonstration could lead to a train of small satellites that work together to track storms around the world. By measuring the evolution of clouds from the moment of the start of precipitation, a TEMPEST constellation mission, collecting multiple data points over short periods of time, would improve our understanding of cloud processes and help to clear up one of the largest sources of uncertainty in climate models. Knowledge of clouds, cloud processes and precipitation is essential to our understanding of climate change.
What is a CubeSat, anyway? And what’s the U for?
CubeSats are small, modular, customizable vessels for satellites. They come in single units a little larger than a rubix cube - 10cmx10cmx10cm - that can be stacked in multiple different configurations. One CubeSat is 1U. A CubeSat like TEMPEST-D, which is a 6U, has, you guessed it, six CubeSat units in it.
Pictured above is a full-size mockup of MarCO, a 6U CubeSat that recently went to Mars with the Insight mission. They really are about the size of a cereal box!
We are using CubeSats to test new technologies and push the boundaries of Earth Science in ways never before imagined. CubeSats are much less expensive to produce than traditional satellites; in multiples they could improve our global storm coverage and forecasting data.
GOOD fuck you I hope the communities continue to let y’all know just what they think about you.

One Border Patrol agent in Tucson said he had been called a “sellout” and a “kid killer.” In El Paso, an agent said he and his colleagues in uniform had avoided eating lunch together except at certain “BP friendly” restaurants because “there’s always the possibility of them spitting in your food.” An agent in Arizona quit last year out of frustration. “Caging people for a nonviolent activity,” he said, “started to eat away at me.”
Border patrol agents in this article: *admits to abusing and ignoring refugees at the border, notes they’re getting away with unchecked cruelty that even their families hate them for, that many of the agents assault and rape their co-workers, that dangerous agents are being purposefully hired, that they’re holding people in dangerous conditions including children and babies, and that they regularly refer to migrants as “wets” (short for “wetbacks”) and “toncs” because “It’s the sound a flashlight makes when you hit a migrant in the head with it.”*
Also border patrol agents in this article: WHY WON’T YOU RESPECT US - I can’t even relax at home anymore because of all the RHETORIC!!
