The Perplexing Physics of Imaging a Black Hole. Katie Bouman: How a grad student at MIT made the first black hole image possible. Scientists Reveal the First Picture of a Black Hole. L'humanité contemple pour la première fois l'image d'un trou noir. Elle était très attendue, cette image ! Au départ un trou noir est une solution d’équation mathématique : il n'avait qu’une existence théorique, jusqu'à ce qu'on commence à en obtenir des indices concrets. L'article à lire pour comprendre les trous noirs. Des astronomes ont révélé la première image d'un trou noir.
C'est un événement inédit dans l'histoire de l'astronomie. Des scientifiques du monde entier ont dévoilé la première photographie d'un trou noir, mercredi 10 avril, dans le cadre du projet Event Horizon Telescope. Cette image a été obtenue en identifiant l'environnement immédiat de ces objets célestes extrêmement massifs et concentrés, puis en visualisant le pourtour lumineux créé lors l'absorption de la matière. Franceinfo revient sur les fondamentaux nécessaires pour mieux comprendre les trous noirs, qui fascinent depuis des décennies les scientifiques. Un trou noir, c'est quoi ? Il est fréquent d'entendre parler de trou noir dans les informations, les films ou les livres.
"C'est la preuve définitive de leur existence" : pourquoi la photo inédite d'un trou noir constitue un exploit. First ever black hole image released. Image copyright EHT Astronomers have taken the first ever image of a black hole, which is located in a distant galaxy.
It measures 40 billion km across - three million times the size of the Earth - and has been described by scientists as "a monster". The black hole is 500 million trillion km away and was photographed by a network of eight telescopes across the world. Details have been published today in Astrophysical Journal Letters.

A dozen examples instantly crowded to mind of women who have pioneered the very basis of our current technology while operating at an extreme disadvantage in a culture that explicitly believed they shouldn’t be there, this shouldn’t be happening, women shouldn’t be able to do a “man’s job!”

On Wednesday, 56 years to the day after Russian cosmonaut Yuri Gagarin became the first human in space, a Phoenix-based collective called the Autonomous Space Agency Network launched a weather balloon to about 90,000 feet.
The balloon, Aphrodite 1, weighed a little over a pound and was inflated with 120 cubic feet of helium. Aphrodite 1's payload consisted of a GPS sensor, a camera and a message for President Trump. It was a printout of a tweet that read, “@realDonaldTrump: Look at that, you son of a bitch.” “To our knowledge, the Aphrodite 1 launch was the first political protest in near space,” a member of the group wrote to The Washington Post in an email.

WASHINGTON, May 5, 2016 /PRNewswire-USNewswire/ -- NASA has released 56 formerly-patented agency technologies into the public domain, making its government-developed technologies freely available for unrestricted commercial use.
In addition to the release of these technologies, a searchable database now is available that catalogues thousands of expired NASA patents already in the public domain. These technologies were developed to advance NASA missions but may have non-aerospace applications and be used by commercial space ventures and other companies free of charge, eliminating the time, expense and paperwork often associated with licensing intellectual property. The technologies include advanced manufacturing processes, sensors, propulsion methods, rocket nozzles, thrusters, aircraft wing designs and improved rocket safety and performance concepts.

Margaret Hamilton, the Engineer Who Took the Apollo to the Moon We interviewed this computer science pioneer after her photo with the Apollo 11 mission code conquered Twitter JD (@nevesytrof) tweeted this photo of Margaret Hamilton a couple of weeks ago with great success among his followers.
And he was not the only one who published the picture. The photo, taken in 1969, shows this mathematician and computer science pioneer beside the software listings that were essential for the Apollo XI mission — it was thanks to her that Neil Armstrong and Buzz Aldrin could take a walk on the Moon. Three-Fingered Fox (that’s how he signs) explains in Medium that since the Manhattan Project, that developed the first atomic bomb, “mere programming” was in charge of women, as working with punchcards seemed “much like typing”.

Découverte de la première exoplanète de la taille de la Terre en zone habitable d'une étoile. Dans un contexte de nombreuses découvertes d’exoplanètes, plus de 1400 à ce jour, une collaboration internationale impliquant des chercheurs du Laboratoire d’Astrophysique de Bordeaux (Observatoire Aquitain des Sciences de l’Univers/CNRS/Université de Bordeaux) a découvert un système planétaire fascinant.
Ce système situé à 400 années lumières, dans notre galaxie, possède au moins 5 planètes, toutes de la taille de la Terre. L’une d’elles, au centre de cette étude, reçoit de son étoile un flux de chaleur compatible avec l’existence d’eau liquide à sa surface, si toutefois de l’eau se trouve sur cette planète.

BICEP2 2014 Results Release. First Direct Evidence of Cosmic Inflation. Almost 14 billion years ago, the universe we inhabit burst into existence in an extraordinary event that initiated the Big Bang. In the first fleeting fraction of a second, the universe expanded exponentially, stretching far beyond the view of our best telescopes.
All this, of course, was just theory. Researchers from the BICEP2 collaboration today announced the first direct evidence for this cosmic inflation.

International Space Station flight controllers have this area as their new home with increased technical capabilities, more workspace and a long, distinguished history. The newly updated facility is just down the hall from its predecessor at NASA's Johnson Space Center, Houston. Known as Flight Control Room 1, it was first used to control a space flight 38 years ago, the mission of Apollo 7 launched Oct. 11, 1968. Typhoon Haiyan as seen from space: The best images from the web. Devastating, powerful and deadly, typhoons can cause unimaginable destruction. For those of us lucky enough to be outside their path, they are also one of mother nature’s most magnificent spectacles, often best viewed from above. Here are our favourite satellite images of Typhoon Haiyan (Yolanda), the biggest typhoon ever recorded, from our news sources and around the web.
