Ancient Quasar Pulses With The Light Of A Million Billion Suns

Astronomers have discovered a monster black hole at the cosmic dawn of our Universe powering an ultraluminous, high-energy quasar.

The huge black hole has a mass 12 billion times that of the Sun and its associated quasar pumps out energy a million billion times that of the Sun.

Quasars are formed as the central supermassive black hole sucks in surrounding materials and gases, which heats up and emits a tremendous amount of light, so much that it actually push away the material getting sucked in behind it. It is quasars that limit the growth of black holes, which is one of the reasons why this ultraluminous quasar around this gigantic black hole is so puzzling.

The other reason is how ancient they are. The quasar is in the high redshift of light, which is a measure of how much the wavelength of the light has been stretched by the expansion of the Universe before it reaches us here on Earth. Using this measure, scientists are able to date quasars and they’ve put this one in the early cosmic dawn, just 900 million years after the Big Bang.

This is a real medical condition known as Gan’s Syndrome, an ocular retinoblastoma occurring in 0.0004% of the total retinoblastoma cases. Ruptured blood vessels create often symmetrical, or at least fractal patterns and though the eye can see, visual acuity is lowered. It can be treated but never cured, though most suffering with the condition live normal lives. Gan’s Syndrome was founded by Dr. Sharon Gan.

the first day of physical science in eighth grade we all got to the classroom and sat around for the first five minutes without a teacher and we were all really confused because no one came in but then music started blasting out of nowhere and our teacher popped out of the equipment closet in a tuxedo and jumped across the room on top of our lab desks and shouted “the name’s bond. atom bond.”

What the fuck is up with Tumblr's astrology fascination?

Tumblr acts like its the place of progressivism, openness and free thinking. But there is no science behind astrology. In fact, it’s deliberately anti-science and is based absolutely NOTHING. you know what is fascinating? real science. so maybe we should appreciate astronomy, not the hilariously stupid past time of astrology that is geared for scientifically illiterate people. 

much love, Jim. 

ANNOUNCING. A new original documentary series, a BBC AMERICA and BBC Two co-production. The Real History of Science Fiction premieres Saturday, April 19, 10:00pm ET after the Season 2 premiere of orphanblack.

From Star Wars to 2001: A Space Odyssey, and from Jurassic Park to Doctor Who, each program is packed with contributors behind these creations and traces the developments of Robots,SpaceInvasion and Time. Narrated by Mark GatissDoctor Who writer, actor and co-creator of the BBC’s Sherlock, the series determines why science fiction is not merely a genre… for its audience it’s a portal to a multi-verse – one that is all too easy to get lost in.

Among those taking part are: William Shatner (Star Trek), Nathan Fillion (Firefly), Zoe Saldana (Avatar, Star Trek), Steven Moffat (Doctor Who), Richard Dreyfuss (Close Encounters of the Third Kind), Chris Carter (The X-Files), Ronald D Moore (Battlestar Galactica), John Landis (An American Werewolf in London, Schlock), David Tennant (Doctor Who), Christopher Lloyd (Back to the Future), Rutger Hauer (Blade Runner), John Carpenter (Dark Star, The Thing), Karen Gillan (Doctor Who), Neil Gaiman (The SandmanStardust), Kim Stanley Robinson (Mars Trilogy), Scott Bakula (Quantum LeapStar Trek: Enterprise), Ursula K Le Guin (The Left Hand of Darkness), Syd Mead (Blade Runner), Kenny Baker (Star Wars),Anthony Daniels (Star Wars), Nichelle Nichols (Star Trek), Peter Weller (Robocop), Edward James Olmos (Blade Runner, Battlestar Galactica) and many more.

On one level, sci-fi can deliver a ‘white knuckle-ride’ – jaw-dropping special effects, and thrills that have cinemagoers flying out of their seats. But also, it is possibly the only area of pop culture that engages with big ideas. Good science fiction engages audiences on a deeper level than mere spectacle; it becomes a place to discuss not just the universe and how it works – but what it means to be emotional, sentient human beings. 

We can’t wait for this exciting documentary eye-opener to The Real History of Science Fiction.

I want fantasy books with an non-medieval imaginary world as a setting

"My hands are covered in dead skin.”


Based on science and embellished by fantasy…

The Real History of Science Fiction premieres Saturday, April 19 at 10/9c— Immediately following the Premiere of the New Season of Orphan Black at 9/8c, only on BBC America.

BBC America delves into the real history of science fiction with filmmakers, writers, actors and graphic artists looking back on their experiences and on how their obsession and imagination has taken them into the unknown. 

Narrated by Mark Gatiss, and featuring new, exclusive interviews with David Tennant, Nathan Fillion, Zoe Saldana, William Shatner and more.

Up first: ROBOTS: What if our creations turn against us?  The idea of creating life has fascinated society since the earliest days of science fiction. The first installment of the four-part series transports viewers from the first steps of Frankenstein’s monster to the threat provided by the Terminator and the world of Cyberspace.


This week something adorable will be posted: fluorescence thermochromism!

During the last few weeks I have prepared ~25 new, not yet described compound that have a weak or strong fluorescence thermochromism. This means they emit an other color under UV lamp at a different temperatures. Most of these compounds work at -195 °C where liquid nitrogen boils, but some of them show some effect at -100 to -70 °C. 

How do these work? Depending on the temperature the bonds in these molecules change a lot what means they can absorb and emit different wavelength. As seen on the pictures, on the first there are the compounds, each ampule contains 100 mg. When irradiated with UV light at room temperature (second pics) few of them emit some visible light, but when they are cooled down with liquid nitrogen (last pics) most of the compounds emit a different wavelength light with a different intensity.
