The Event Horizon Telescope has captured a photo of a supermassive black hole at the center of M87, a galaxy 54 million light years away.

Event Horizon Telescope collaboration et al.

 

In the century since Einstein predicted the existence of black holes in his theory of gravity, astrophysicists have turned up overwhelming evidence for the things. They’ve observed the push and pull of black holes on the orbits of nearby stars and planets. They’ve heard the vibrations, or gravitational waves, resonating from black holes colliding. But they’d never glimpsed a black hole face to face—until now. On Wednesday, astrophysicists announced they had captured the first-ever image of a black hole.

The picture, taken over five days of observations in April 2017 using eight telescopes around the world by a collaboration known as the Event Horizon Telescope, depicts luminous gas swirling around a supermassive black hole at the center of M87, a galaxy 54 million light-years away. Past the bright lights, though, is the black hole’s telltale feature: its event horizon. The event horizon is the edge of the spacetime abyss, where gravity is so strong that no light can escape from it. “It’s the point of no return,” says Feryal Özel of the University of Arizona, who is a member of the EHT collaboration. In the image, it manifests itself as the “sudden absence of light,” she says.

Previously, researchers had captured a blobby jet of light emerging from where the M87 black hole was predicted to be—but they couldn’t definitively see the black hole because their instruments were nowhere near as sharp as EHT’s. “It’s like going from a cheap smartphone camera to a high definition IMAX cinema,” says astrophysicist Andrew Strominger of Harvard University, who was not involved in the work.

This black hole is about 6.5 billion times the mass of the sun. Still, it’s tiny from a vantage point on Earth, just 50 microarcseconds wide in the sky, which makes it about as hard to see as a donut placed on the moon. It took eight different telescopes to image it. The telescopes collected observational data that was synced with the precision of a billionth of a second.

To see the black hole’s boundary between light and dark, the astrophysicists captured radio waves—light 1.3 millimeters in wavelength, invisible to the human eye—emitted by the gas swirling around the black hole. The gas emits light of all different wavelengths, including visible light, but the researchers chose this particular wavelength because it can sail through entire galaxies and even Earth’s own atmosphere without being absorbed. But they still needed good weather at all eight of their telescope sites to see the black hole. Before switching on their telescopes, they had to monitor the moisture in the air, says Özel—too much humidity would ruin their images. To minimize the chance of rain, they built the telescopes in dry regions, including the South Pole and the Atacama Desert in Chile.

M87’s black hole is relatively close to Earth, as the light coming from it was only emitted 54 million years ago—so we’re seeing it at a more mature moment in its existence. “At this point in the age of the universe, black holes have calmed down,” says Özel. “They’re basically eating gas trickling in from nearby stars.” M87’s black hole does emit bright jets of gas, but it’s still pretty dim compared to younger black holes that are further away. These younger black holes accumulate larger amounts of matter, so their swirls of luminous gas shine brighter.

Seattle-based studio Pb Elemental has recently completed the Phinney Modern house project.

This 2,150 square foot contemporary home is located in Seattle, Washington.

 

 

This 2,510 sqft single family home is located in Seattle’s Phinney Ridge neighborhood. The home was designed for a young family on a small in-fill lot. The lot was very challenging just over 2,000 sft with a access easement covering a portion of the southwest corner. This created a situation where the building footprint covered the majority of the yard, so it was essential to capture outdoor space on the structure. This led to the reverse floorplan (living on the third level), allowing the main spaces to easily access outdoor space, light and view.

The homeowners created a welcoming contrast by their choices in furniture and wall coverings. To maintain a visual connection to the street we designed the stair to the main living level to be transparent so you can see and feel the activity. The upper level opens to a West facing deck and exterior stair leading to a view roofdeck which overlooks Ballard and the Puget Sound.

Dressed in Light: Fine Art Photo Series by Dani Olivier

To shoot these stunning nude portraits, Paris-based photographer Dani Olivier dressed his models with nothing but light, using their bodies as a canvas, combined with a series of geometric patterns to celebrate the beauty of the female form.
“Dani Olivier began working with light projections some eight years ago, and he’s been refining the process ever since. He prefers to collaborate with dancers and other women who move to the beat of their own drums, whose bodies can ripple through space alongside the projected motif. These seductive portraits of women are a subtle but lovely reimagination of both the nude as an art form as well as the medium of light.”

Apartment Portugal, a stylish apartment located in São Paulo, Brazil, was designed in 2017 by Gabriel de Lucca from the architectural firm GDL Arquitetura. It covers a total ground area of 140 square meters, and was designed for a family who required integrated spaces.

The architectural firm sought to create a large and fluid space that would take advantage of the natural lighting conditions the apartment enjoys by eliminating partitions and uniting all the individual rooms to form a spacious whole.
