Astronomers discover black hole with 140 trillion times more water than Earth

Two teams of astronomers have discovered the largest and farthest reservoir of water ever detected in the universe. The water, equivalent to 140 trillion times all the water in the world’s ocean, surrounds a huge, feeding black hole, called a quasar, more than 12 billion light-years away Centos linux download.

“The environment around this quasar is very unique in that it’s producing this huge mass of water,” said Matt Bradford, a scientist at NASA’s Jet Propulsion Laboratory in Pasadena, Calif 항아리게임 pc 다운로드. “It’s another demonstration that water is pervasive throughout the universe, even at the very earliest times.”

A quasar is powered by an enormous black hole that steadily consumes a surrounding disk of gas and dust 무료 오디오북 mp3 다운로드. As it eats, the quasar spews out huge amounts of energy. Both groups of astronomers studied a particular quasar called APM 08279+5255, which harbors a black hole 20 billion times more massive than the sun and produces as much energy as a thousand trillion suns 쇼퍼홀릭 다운로드.

Astronomers expected water vapor to be present even in the early, distant universe, but had not detected it this far away before. There’s water vapor in the Milky Way, although the total amount is 4,000 times less than in the quasar, because most of the Milky Way’s water is frozen in ice 다운로드.

 

And, the instruments they used:

Bradford’s team made their observations starting in 2008, using an instrument called “Z-Spec” at the California Institute of Technology’s Submillimeter Observatory, a 33-foot (10-meter) telescope near the summit of Mauna Kea in Hawaii 모바일 네이트 온. Follow-up observations were made with the Combined Array for Research in Millimeter-Wave Astronomy (CARMA), an array of radio dishes in the Inyo Mountains of Southern California 다운로드.

The second group, led by Dariusz Lis, senior research associate in physics at Caltech and deputy director of the Caltech Submillimeter Observatory, used the Plateau de Bure Interferometer in the French Alps to find water 다운로드.

Searching for the perfect Panna Cotta dessert recipe

I’ve spent a good chunk of the last two weeks surrounded by spreadsheets, crumpled paper packets, cartons of dairy products and dirty ramekins 다운로드. Josef Centeno has a lot to answer for.

A couple of weeks ago I stopped in at his Bäco Mercat restaurant downtown for a lunch that ended with one of the best panna cottas I’ve ever had 다운로드. You know what I mean: Delicately sweet, it was like a dream of cream held together by faith and just a little bit of gelatin.

It struck me — how long had it been since I’d had panna cotta 미드타운 매드니스2 다운로드? A few years ago you couldn’t go anywhere without seeing it. Then just as suddenly it went away. It makes no sense. A good panna cotta is as good as dessert gets 다운로드. Vowing I would never again leave my panna cotta cravings to the whims of restaurant fashion, I determined to master the dish.

How hard could that be 아이폰 유튜브 다운로드?

 

…it turns out pretty hard, here’s the full story, and scroll to the last paragraphs for the perfected recipe:

Kickstarter project: build a NYC park in an abandoned, underground trolley terminal

We want to transform an abandoned trolley terminal on the Lower East Side of Manhattan into the world’s first underground park, called Lowline 한국드라마 다운로드.

This space is quite large, by New York standards: 60,000 square feet, or 1.5 acres. It was built in 1903 as a trolley terminal, for streetcars traveling over the Williamsburg Bridge, and has been out of operation since 1948 다운로드. We fell in love with the site because of its architectural details: old cobblestones, crisscrossing rail tracks, vaulted 20-foot ceilings, and strong steel columns 다운로드.

To build this park, we’re planning to use a cutting-edge version of existing technology– which we’ve already built in prototype 지방의 누명 다운로드. It uses a system of optics to gather sunlight, concentrate it, and reflect it below ground, where it is dispersed by a solar distributor dish embedded in the ceiling 킹스맨 유료 다운로드. The light irrigated underground will carry the necessary wavelengths to support photosynthesis– meaning we can grow plants, trees, and grasses underground 다운로드. The cables block harmful UV rays that cause sunburn, so you can leave the SPF-45 at home. Sunglasses optional (for cool kids).

We think a year-round public space will be valuable for everyone 꽃보다 청춘. Farmers markets and vendor stands can feature fresh produce and locally made goods, supporting local and sustainable businesses. Art installations, concerts, and performances can help showcase the incredible creative spirit of the Lower East Side 봄의왈츠. Youth programming and educational opportunities can offer rich experiences for kids and parents. And a safe haven from the hectic feel of Delancey Street will serve as relief in a very car-centric corner of Manhattan 웨이보 영상 다운로드.

When it’s really cold, or pouring rain, how much fun is it to hang out in Central Park? The High Line? Not so much. The LowLine can be the 21st century answer to traditional parks: instead of building up, let’s build down 다운로드!
