The ultraviolet photons that the light is made of convert into charged ions, or ionizing photons, which come from quasars and hot young stars.

Scientists discovered the discrepancy during recent observations from Hubble Space Telescope’s Cosmic Origins Spectrograph.

Kollmier said: “Either our accounting of the light from galaxies and quasars is very far off, or there’s some other major source of ionizing photons that we’ve never recognised. We are calling this missing light the photon underproduction crisis. But it’s the astronomers who are in crisis—somehow or other, the universe is getting along just fine.”

Study co-author Ben Oppenheimer said that if the light is really missing it would be a huge surprise as “intergalactic hydrogen is the component of the Universe that we think we understand the best”.

Neal Katz, also a co-author of the paper, added: “The most exciting possibility is that the missing photons are coming from some exotic new source, not galaxies or quasars at all.”

Proposing another theory, he said the light could be coming from dark matter that holds galaxies together, but has never been seen directly. “You know it’s a crisis when you start seriously talking about decaying dark matter!” he added.

VIVA LA PLUTO MOTHERFUCKERS!!!!

DO YOU SEE THIS? DO YOU? ALL OF YOU WHO HAD WRITTEN OFF PLUTO, WHO HAD CROSSED IT OFF YOUR PLANET LIST? REMEMBER HOW IT WAS ‘TOO SMALL” TO BE A PLANET? HOW NASA, IN COLLABORATION WITH THE INTERNATIONAL ASTRONOMICAL UNION REMOVED ITS PLANETARY STATUS AND  CHANGED ITS NAME TO 134340? HOW EVERYONE THEN CONSIDERED THERE TO BE EIGHT PLANETS, NOT NINE?

BUT SOME OF US REMAINED LOYAL TO PLUTO. IT WAS NEVER FORGOTTEN. AND NOW HERE WE ARE, AND JUSTICE IS UPON US AFTER 8 YEARS.

BECAUSE GUESS WHAT? PLUTO HAS AT LEAST FIVE MOONS, A PRETTY BIG NUMBER FOR A ”DWARF-PLANET”, HUH? ESPECIALLY WHEN EARTH, QUITE BIGGER THAN PLUTO AND AN OFFICIAL PLANET ONLY HAS ONE. AND GUESS WHAT ELSE? ERIS, THE PLANET WHICH EVERYONE THOUGHT TO BE BIGGER THAN PLUTO, MAY NOT BE BIGGER AFTER ALL. AND THE BEST PART IS THAT PLUTO HAS AN ATMOSHPERE. THAT’S RIGHT, LADIES AND GENTLEMEN, A SUPPOSEDLY NON-PLANET HAS AN ATMOSPHERE. AGAIN, ISN’T THAT IMPRESSIVE?

SO LOOK AT THIS. NEW FINDINGS, AND A NEW AGE FOR PLUTO. AN AGE OF RECOGNITION AND APPRECIATION. AND ALLOW ME TO CLOSE THIS -somewhat aggressive-PRESENTATION OF OPINION WITH THE MOTTO OF THE PLUTO APOLOGISTS: VIVA LA PLUTO!

Y’all really feel strongly about Pluto

eris was originally named xena and eris’ moon dysnomia was originally named gabrielle and if you don’t think that’s the tightest shit then get out of my face.

pluto has more known moons bc we’ve been watching it longer and are sending a ship there. until next summer we won’t even know //pluto’s// actual size, and until we have an actual size for eris it’s all guesswork.

but listen, the dwarf planet subcategory was inevitable, there are already two dozen known dwarf candidates. with something like two hundred small bodies unafilliated with the major planets out in the kuiper belt, and something like //ten thousand// out into the oort cloud, there were never going to be that many official planets. and if as it looks now eris and pluto are basically the same size, that just makes their subcategorization //more// justifiable, not less.

pluto is great - also literally nobody ever stopped calling it that, we name //asteroids// ffs - but what it is not, any longer, is an outlier. in 1930 it looked like a planet and behaved more or less like a planet so we called it a planet. but our awareness of the damn thing is younger than my grandparents. in 1930 jupiter had only nine moons, whereas today we’ve identified //sixty seven//. calling pluto a planet but not the other dozen candidates is wierdly dependent on astronomical precedent from decades before the hubble.

pluto was always a wierd little planet anyways, with an eccentric orbit more suggestive of a lost gas giant’s ejected moon(s) than an independant body doing it’s own thing. and if you’re dissing eris but saying pluto should get it’s status back, guess what, either they both are or it’s a wash. four inner rocky planets, four major gas giants, and thousands of outer dwarfs, with pluto and eris as their king and queen.

{until we actually do find something bigger out there.}

NASA’s annual budget is half a penny on your tax dollar. Imagine what we could do with a full penny. http://bit.ly/-Imagine

The Penny4NASA campaign was founded to highlight how dramatically underfunded NASA has become in recent years. NASA’s appropriations budget for FY2014 is currently $17.6 billion, representing 0.48% of the U.S. federal budget, or less than half a penny on your tax dollar. We are firmly committed to seeing NASA funded to a level commensurate with the tremendous economic, technological and inspirational value it confers. With your help we can get NASA the funding it deserves! http://www.penny4nasa.org/take-action/

She is a cosmic dancer in a blissful abyss.
She is stellar.
A skintight cosmos.
A spontaneous creation

Tampons were packed with their strings connecting them, like a strip of sausages, so they wouldn’t float away. Engineers asked Ride, “Is 100 the right number?” She would be in space for a week. “That would not be the right number,” she told them. At every turn, her difference was made clear to her. When it was announced Ride had been named to a space flight mission, her shuttle commander, Bob Crippen, who became a lifelong friend and colleague, introduced her as “undoubtedly the prettiest member of the crew.” At another press event, a reporter asked Ride how she would react to a problem on the shuttle: “Do you weep?”

Star Birth in the Carina Nebula
A towering “mountain” of cold hydrogen gas laced with dust is the site of new star formation in the Carina Nebula (NGC 3372). The great gas pillar is being eroded by the ultraviolet radiation from the hottest newborn stars in the nebula. This portion of the Carina Nebula is home to some of the most intense star formation in the Milky Way galaxy.
