Comments Off on Scientists find a massive black hole swirling in the Milky Way

Scientists from Keio University in Japan have unveiled the best evidence we have for an intermediate-mass black hole – and it’s right in our Milky Way . Intermediate-mass black holes have eluded astronomers , who have found hints of both star-sized black holes and supermassive black holes . But the discovery of the mid-sized black hole could help scientists understand why supermassive black holes grow so immense. The formation of supermassive black holes has been a mystery for astronomers, but this new study might provide an explanation for how they form. The researchers from Japan said in their research that mid-sized black holes could merge to form supermassive black holes, but there’s been little evidence for the existence of intermediate-mass black holes – until now. Related: Supermassive black holes offer hint at structure of the universe Last year, a team led by Tomoharu Oka of Keio University reported a strange cloud of molecular gas, dubbed CO-0.40-0.22, in our Milky Way. A team also led by Oka then scrutinized the cloud with instruments such as the Atacama Large Millimeter/submillimeter Array (ALMA) and found a dense clump of gas near the cloud’s center, and a nearby radio wave source, CO-0.40-0.22*, that has similarities to the supermassive black hole Sagittarius A*. According to Oka, the similarity “supports the notion that CO-0.40-0.22* is an intermediate-mass black hole.” Scientists have expressed excitement about the discovery; Swiss Federal Institute of Technology astronomer Kevin Schawinski told Science Magazine, “It’s a very careful paper and they have gorgeous data. It’s the most promising evidence so far.” If CO-0.40-0.22* is verified as a black hole, its presence could offer support to the idea our galaxy has gotten bigger by cannibalizing smaller neighboring galaxies. The Japanese scientists think CO-0.40-0.22* could be a former dwarf galaxy core that could have been absorbed into the Milky Way, and could one day be subsumed by Sagittarius A*. The journal Nature Astronomy published the study online this week. Via Keio University , Science Magazine , and ScienceAlert Images via Keio University and NASA/JPL-Caltech

Spectacular mountain-like Valley breaks ground in Amsterdam

Comments Off on Spectacular mountain-like Valley breaks ground in Amsterdam

A jagged mountain-like mass is turning up on Amsterdam’s pancake-flat landscape. MVRDV recently broke ground on Valley, a 75,000-square-meter mixed-use development that looks like a cluster of mountain peaks covered in greenery. Located in Amsterdam’s Central Business District Zuidas, the competition-winning design for OVG Real Estate will aim for BREEAM-NL Excellent rating and comprise apartments, offices, underground parking, a sky bar, and various retail and cultural facilities. Selected as the competition winner by the Municipality of Amsterdam in 2015, the stunning Valley project seeks to transform the quickly developing Zuidas area into a more livable and complete urban quarter. The green-terraced towers are designed as three mountain-like peaks of varied heights that soar to a maximum of 100 meters. The Valley will include 196 apartments, seven stories of office space, a three-story underground parking garage with 375 parking spots, and a variety of retail and cultural options on the lower floors. The publicly accessible Sky bar, which spans two stories, will offer panoramic views across the city. “Valley combines residential apartments with a green environment that offers panoramic views of Amsterdam”, says Winy Maas, MVRDV co-founder. “A lively plinth offering a range of commercial activities has some offices above and is topped finally with residences. The carving out of the resulting block ensures that it becomes less introverted than existing buildings in the Zuidas. There will be many terraces, both private and public, filled with people, flowers, plants and outdoor seating.” Related: BIG unveils lush mountain-like terraced building infused with nature The jagged building will be clad in natural stone and the layout informed by digital tools to optimize access to natural daylight and views, while preserving privacy. Due to the unique layout, no two apartments will be alike. MVRDV collaborated with award-winning garden designer Piet Oudolf and Deltavormgroep on the landscape design, which features an abundance of outdoor space and landscaped terraces. The publicly accessible central valley-area—from which the project derives its name—spreads across the fourth and fifth floor between the towers’ residential and commercial areas and will have an attractive year-round green appearance. + MVRDV Images via MVRDV
