Titan’s Atmosphere

Titan is the largest moon of Saturn. It is the only natural satellite known to have a dense atmosphere, and the only object other than Earth for which clear evidence of stable bodies of surface liquid has been found

Titan is primarily composed of water ice and rocky material. Much as with Venus prior to the Space Age, the dense, opaque atmosphere prevented understanding of Titan’s surface until new information accumulated with the arrival of the Cassini–Huygens mission in 2004, including the discovery of liquid hydrocarbon lakes in Titan’s polar regions.

The atmosphere is largely nitrogen; minor components lead to the formation of methane and ethane clouds and nitrogen-rich organic smog. Titan’s lower gravity means that its atmosphere is far more extended than Earth’s and about 1.19 times as massive. It supports opaque haze layers that block most visible light from the Sun and other sources and renders Titan’s surface features obscure. Atmospheric methane creates a greenhouse effect on Titan’s surface, without which Titan would be far colder. Conversely, haze in Titan’s atmosphere contributes to an anti-greenhouse effect by reflecting sunlight back into space, cancelling a portion of the greenhouse effect warming and making its surface significantly colder than its upper atmosphere.

Titan’s clouds, probably composed of methane, ethane or other simple organics, are scattered and variable, punctuating the overall haze.The findings of the Huygens probe indicate that Titan’s atmosphere periodically rains liquid methane and other organic compounds onto its surface. Clouds typically cover 1% of Titan’s disk, though outburst events have been observed in which the cloud cover rapidly expands to as much as 8%. One hypothesis asserts that the southern clouds are formed when heightened levels of sunlight during the southern summer generate uplift in the atmosphere, resulting in convection. This explanation is complicated by the fact that cloud formation has been observed not only after the southern summer solstice but also during mid-spring.

Unlike the beautiful 6-year old Jonbenett Ramsey who received coverage all over the media - every tabloid, newspaper, news channel, talk show, 7-year old Aiyana Stanley was killed by a police officer during a raid while she was sleep and her murder received very little coverage.
Police, searching for a murder suspect, threw a flash grenade through the window of her family’s apartment around midnight. According to Aiyana’s father, it landed on the couch, setting Aiyana on fire. A police officer’s gun then went off, and shot Aiyana in the neck.
Aiyana was asleep on the living room sofa in her family’s apartment when Detroit police, searching for a homicide suspect, burst in and an officer’s gun went off, fatally striking the girl in the neck, family members said.
Her father, 25-year-old Charles Jones, told The Detroit News he had just gone to bed early Sunday after covering his daughter with her favorite blanket when he heard a flash grenade followed by a gunshot. When he rushed into the living room, he said, police forced him to lie on the ground, with his face in his daughter’s blood.
“I’ll never be the same. That’s my only daughter,” Jones told.
We haven’t forgotten about you baby. R.I.P.

We haven’t forgotten.

Excellent advice from (arguably) the coolest physicist to have ever lived, Richard Feynman: you don’t have to be a genius to want to study science, you just have to work hard!
Edit: just realized the initial quote reads: “ordinary” rather than “normal” — our apologies for the screw up!

photos by gerry ellis from the david sheldrick wildlife trust, a nursery and orphanage for elephants in kenya’s tsavo east national park. here, fifty five keepers are charged with being around the clock parents to an elephant. the elephants, however, are the ones who chose their caretakers; it is the keepers who must ingratiate themselves to the elephants and earn their trust.

when elephants first arrive at the orphanage they are often traumatized from having witnessed the slaughter of their mothers and family by poachers. grieving can last several months, and they often lose the will to live. but as dame daphne sheldrick, founder of the orphanage, explains, a caretaker is charged with “persuading an elephant to live when it wants to die.”

approximately 35,000 elephants are killed by humans every year. with an estimated 350,000 elephants left in the whole continent of africa, they will be gone in the wild within ten years.

cbc’s the nature of things did a program on the elephants and their caretakers. you can foster an elephant with the david sheldrick wildlife trust online here. for more on the emotional lives of elephants, as well as the david sheldrick wildlife trust and other human efforts to save them, check out these posts

THIS.

I have never thought about it in this context
that’s actually really, really creepy.

I… fuck.

Yeah, basically.

I once pointed this out to my mother and she just stared at me, in stunned silence for ages. 

There will always be a girl who is less sober, less secure, with less friends walking in a darker part of town. I want her safe just as much as I want me safe.

Interesting how we’re always hearing how shameful and irresponsible it is to be a teen mom.

But we never hear the same messages directed at teen dads.

Or even the words “teen dad”.

It’s almost like society demonizes women’s sexuality and sexual choices while absolving men of all sexual responsibility and judgement.

New York policeman involved in fatal ‘chokehold’ arrest stripped of badge

image

Officer Daniel Pantaleo, an eight-year NYPD veteran, and an officer who has been with the force for four years taken off the street after man dies in custody following arrest using ‘chokehold’

Partial video of the encounter obtained by the New York Daily News shows the 6-foot-3, 350-pound (1.9-meter, 159-kilogram) Mr Garner becoming irate and refusing to be handcuffed as officers tried to arrest him on suspicion of selling untaxed, loose cigarettes on a sidewalk.

The video then shows one of the officers placing Mr Garner in what Police Commissioner William Bratton said on Friday appeared to be a chokehold. The tactic, which can be fatal, is prohibited by departmental policy.

In the video of the arrest, Mr Garner, who has been arrested for selling illegal cigarettes numerous times in recent years, says he hasn’t done anything wrong.

"Every time you see me, you want to mess with me. I’m tired of it. It stops today," Mr Garner shouts. "I’m minding my business. Please just leave me alone."

As four officers bring him down, Mr Garner is heard gasping, “I can’t breathe! I can’t breathe!” The video shows one officer using his hands to push Mr Garner’s face into the sidewalk.

Prosecutors and internal affairs detectives are investigating the death of the father of six and grandfather of two; authorities believe he suffered a heart attack. Mr De Blasio has called the circumstances of his death “very troubling.”

Another stop and frisk fatality, and death to the black man. NYPD get your fucking shit together and please, almighty judging party, PLEASE dish out the appropriate punishments to those with the blood in their hands (though I am highly pessimistic because the second police officer involved is still allowed to retain his gun and badge, but seriously get that shit out of there as well he should’ve stopped his goddamn colleague). 

This is an authorised system built to hunt and shut down POC like animals who need to be tamed. The bias towards targetting non-whites is extremely stark and it pains me, even as a complete outsider, to see news of such incidents. 

For those shit hags who are all “what the fuck is wrong with stop and frisk it’s a fair thing to keep our streets safe if i were stopped on the streets i’d be totally cool and let them check me” first of all need I bring back this in which this guy named Alvin (totally not white) was stopped and frisked harrassed and provoked by the police in such a manner which is totally disrespectful and is no way at all to treat another human being? And if this video isn’t enough, need I bring in this overlooked but brilliant run down on the situation which was posted a year ago but I’m sure still applies greatly today. Also, probably need to add that a judge was removed for trying to speak up against stop and frisk

Oh god please stop this before anymore young lives are taken away.
