Airglow ripples over Tibet
Why would the sky look like a giant target? Airglow. Following a giant thunderstorm over Bangladesh in late April, giant circular ripples of glowing air appeared over Tibet, China, as pictured above. The unusual pattern is created by atmospheric gravity waves, waves of alternating air pressure that can grow with height as the air thins, in this case about 90 kilometers up. Unlike auroras powered by collisions with energetic charged particles and seen at high latitudes, airglow is due to chemiluminescence, the production of light in a chemical reaction. More typically seen near the horizon, airglow keeps the night sky from ever being completely dark.

Spiral in Serpens
This new NASA/ESA Hubble Space Telescope image shows a beautiful spiral galaxy known as PGC 54493, located in the constellation of Serpens (The Serpent). This galaxy is part of a galaxy cluster that has been studied by astronomers exploring an intriguing phenomenon known as weak gravitational lensing.
This effect, caused by the uneven distribution of matter (including dark matter) throughout the Universe, has been explored via surveys such as the Hubble Medium Deep Survey. Dark matter is one of the great mysteries in cosmology. It behaves very differently from ordinary matter as it does not emit or absorb light or other forms of electromagnetic energy — hence the term “dark”.
Even though we cannot observe dark matter directly, we know it exists. One prominent piece of evidence for the existence of this mysterious matter is known as the “galaxy rotation problem”. Galaxies rotate at such speeds and in such a way that ordinary matter alone — the stuff we see — would not be able to hold them together. The amount of mass that is “missing” visibly is dark matter, which is thought to make up some 27% of the total contents of the Universe, with dark energy and normal matter making up the rest. PGC 55493 has been studied in connection with an effect known as cosmic shearing. This is a weak gravitational lensing effect that creates tiny distortions in images of distant galaxies.

Charda Gregory abducted, humiliated, violated, restrained, scalped and tortured.
If this were reversed, with black police officers who were sworn to uphold peace and justice but instead were documented victimizing a white woman (who was already a victim), this news would have trumped the Olympics!
Truncated version: drugged at a party, abducted to a motel, wakes up during unwanted sexual violation in a motel room full of strangers, fights like hell to escape, motel employee calls the authorities, she gets arrested for destroying motel property and it just gets worst from there.
Every officer who participated in it and even those who witnessed it and did nothing should be punished but instead they just fired the woman?
No rape kit, no police report on the people inside the motel room, no investigation of her claims, no accountability for missing motel entry records, no video from the motel but she gets detained for fourteen days?
(Btw, when did your tax dollars begin purchasing Abu Ghraib type water boarding chairs?)
I get angrier and angrier everyday when I see things like this.
After 306 days, 14 hours, 12 minutes and 43 seconds of flight, over the span of 33 missions, Space Shuttle Orbiter Atlantis, OV-104, on display at Kennedy Space Center Visitor Complex in Titusville, Florida, is now the centerpiece of the most breathtaking aerospace museum presentation I’ve ever visited.
This orbiter flew many relatively important missions, including the final Hubble Space Telescope servicing mission in 2009. STS-125 performed five EVAs during the mission, and restored the important telescope, extending its life well beyond original design spec.
It’s truly surreal to walk up right beside this enormous rocket plane. I found it difficult to take the whole thing in at once. It’s overwhelming in a really good way. I wrote more about the experience, and shared several more photos in a previous post (click here to view).
Tangled comparisons - concept art to the final film.
why the fuck is the concept art so much better
Actually they were going to do crazy cool animation that would make the film a “living oil painting” but it just proved to be too expensive to mass produce
#pirates of the caribbean was kind of a formative influence #so here’s the thing #after years of chasing curses and hearts and fountains; losing the pearl and winning her back and losing her again #after rum enough to drown his sins and sorrows both#captain jack sparrow wakes up one morning and he’s immortal #just like that #no deals with calypso (he hasn’t been able to find her since the brethren court broke her chains) no desperate double-dealing #one morning he just…stops #stops aging stops dying #he gets the seas forever—except #except #the edges of the map are closing in #the lure of undiscovered treasures is waning and merchant ships are becoming better defended #the day that the East India Company takes Shipwreck Island; Jack feels a great chapter in the world’s history close #(he flees to the Barbary coast with the rest of his ilk; but the romance has gone out of it—the is too much desperation #too much hunger too much blood to it nowadays #the age of the swashbuckler won’t live out the decade) #I imagine this thing he’s chased all his life would crumble through his hands as he bounced from ship to ship #he never gets used to the square rigging on the clippers; though they lead to some good work running tea from china #but the first time he sees a steamship he nearly walks off the dock out of shock #of all the ways sailing would have changed; who thought you’d get rid of the /sails/ #(he swears he’s never getting on one of those monstrosities; let alone sailing on one) #(he manages to hold out until 1893 when the longing for the sea overwhelms him and he decides that even #that ghastly smog and the humming of the engines can be endured) #sometimes he’ll see calypso out of the corner of his eye—leaning on the deck railing; darting alongside the ship with the dolphins #(someone in the early 20th century tells him they’re not fish and he nearly busts a gut laughing) #he wears a hundred names and a hundred looks; cuts his hair short or grows it long #calls himself american; spanish; english (british); caribbean #he has two dozen different copies of Stevenson’s Treasure Island—it reminds him of something gone and half-forgotten #and in 1920 when Seitz comes out with Pirate Gold; Captain Jack Sparrow is in the first row (x)
And then in the future, everything changes. He’s been through it all, of course-watched humanity rediscover the heavens above them, watched them begin to wonder what’s out there. He cheered with the rest of the world when they landed on the moon, cheered as if he’d found Isla de la Muerta all over again, because there was something new. New treasure, a new horizon. But then they stop going, stop exploring, and he goes back to riding tankers across the rising seas. So he’s surprised when one day he wakes up from a night with his bottle of rum (his truest companion), and hears that there’s colonies on Mars now, and they need ships to supply them. He spends the next decade crafting new identities, learning all he can to qualify for the job, and after several tries (and even more faked deaths-this immortality thing isn’t all it’s cracked up to be in the age of the inerasable digital self) he gets it. The ships go nearly constantly now, the needs of the terraforming project creating an unbroken line of vessels from Mars to Earth and back again. “Show me that horizon,” he whispers to himself, his personal prayer of thanksgiving, each time they leave orbit, because the worlds, the stars are in motion and it’s never the same, with nearly three years for a round trip the ports are always different, even if they keep the old names. And finally one trip something goes wrong with the reactor, they’re too low on power and have to deploy the backups, and Jack (Lucky Jack, they call him, for he survives too many things he shouldn’t but science has yet to accept that maybe some things weren’t old wives’ tales after all) goes out for the spacewalk to bring up the solar panels. And as they rise, geometric patterns black against the sun’s glare, he’s struck by a powerful sense of déjà vu, because it’s all here-wind and sails, a ship beneath his feet and stars above his head, horizon in all directions. He wonders, for a moment, if the reason he’s still here is because the universe wanted a witness, to mourn the end of one age of exploration, and rejoice in the birth of the next.
Thank you for writing this. It made me cry, but oh I am so relieved to see the yearning for the stars.
That shouldn’t have given me as many feels as it did…
One of the reasons your tuition is high and classes are getting cut.
ARE YOU FUCKING KIDDING ME
fact checked and…apparently this is completely correct.
And people wonder and complain when I am “down” on sports.
Does this include adjuncts? Because they don’t make any more than grad students and are teaching most of your classes.
Happy labor day, kids.
Hope you’re not starting your freshman year at rip-off U.
We have a frog and a pig
a rabbit and a promiscuously drawn woman
a donkey and a dragon
a shape shifting dog and a rainbow unicorn
and a warthog with a meerkat who raise a lion cub
But no one will ever accept the Bee Movie
I thought this was gonna be about gay couples but gee was I mistaken
AvaLynn was attacked by another student on the school playground. We are fighting for answers and for greater supervision at school.
My friend Lacey Harris’s 5 year old daughter was brutalized by another child on the playground at school this week, in Pascagoula, Mississippi. Her face is swollen and bruised beyond recognition, and the only thing the school can tell her is that they “are investigating”
This sweet little 5 year old girl is terrified to return to school. She is in pain and she has been MAIMED. This needs IMMEDIATE media attention. The school and local news are ignoring the mother’s and loved ones’ cries for help. This family needs justice for what has been done to their poor little angel, and not just to be swept under the rug, as the school district is attempting to do. PLEASE shine some light on this situation and force school administration and news media to get some answers!
The mother has started a GoFundMe page to request help for paying medical bills and legal fees, as it looks as though she’s going to have to pursue this route in order to get any justice at all for her little girl. Please, please, share this link on your page. Even if people are unable to donate, please just help us get the word out on what is going on with this poor family.
This is really heartbroken for me and extremely hard to look at.
This is the link to Ava’s donation page.
Please donate and share and PRAY!
God bless you all!
his life was totally in danger.
True story; this officer (John Pike) got a settlement of $38,000 because he said he got depressed after pepper spraying these kids. Oh, the depression wasn’t for feeling remorseful for pepper spraying a bunch of college kids peacefully protesting. He got depressed because he said since the media kept playing the video of him pepper spraying peaceful kids without cause, he got threats and didn’t feel safe. He didn’t feel safe. I’m not making that up. This motherfucker collected nearly 40 grand on worker’s comp after assaulting a bunch of college kids.
im gonna reblog this in hope that it makes him a little bit more depressed.
