Astronomers Find Largest Known Extraterrestrial Water Reserve 183

Posted by timothy from the sticking-with-fiji-water-for-now dept.
gerddie writes "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. One team, lead by Matt Bradford, 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. 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. The second group led, by Dariusz Lisused, used the Plateau de Bure Interferometer in the French Alps to find water. In 2010, this team serendipitously detected water in APM 8279+5255, observing one spectral signature. Bradford's team was able to get more information about the water, including its enormous mass, because they detected several spectral signatures of the water."

      Very good, you almost understand relativity. Hint: the word "now" in your statement has no meaning.

      • He may be correct, so long as he was using the correct place to measure time. "Now" is dependent on your frame of reference, if the frame of reference is earth then "now" there is a metric fuck-ton of water around that super massive black hole, if the frame of reference is there then there may be "now," a lot less. Who know's what "now" via an earth based frame of reference +12 billion years will hold.

      • Hint: the word "now" in your statement has no meaning.

        Sure it does.

        If I'm reading this then:

        a) I exist
        b) The event happened in my recent past.

        That narrows it down to within a couple of dozen years from my point of view. That makes perfect sense to me.

          So you don't understand cosmological terminology, then. "Now" means that whatever we see currently, regardless of how long ago it happened (i.e., regardless of distance), is occurring now.

      The water will be gathered by the black hole, which is still there. The black hole may contain the rest of the ingredients for Kool Aid.

      I wonder if a cosmologist could check the validity of that statement because it seems to neglect universe expansion. Looking online at APM 08279+5255, its redshift is 3.911. Plugging that into wolframalpha indicates the the lookback time is 12bn years, but that the "actual" distance at this time is nearly 23.7bn lightyears.

      Not so much an "ocean"; the water is in the form of vapor, not liquid. It doesn't even look like a cloud, which is condensed water droplets. The density is most likely lower than the best vacuum we've ever pulled on earth. It's a lot of water, but a LOT of space.

  • I have always hoped we would eventually discover proof of life elsewhere in the universe. Maybe this means it is a bit more likely?

    • Doesn't mean it's any more likely. Water is known to be quite abundant in the universe. While finding a whole shitload circling around a black hole is pretty cool, it would be more significant to find a shitload of water on a planet in the so called "Goldilocks Zone" around certain types of stars—for at least the type of life that we know of.

  • Does that mean there was water there 12 billion light-years ago, the light from which we are viewing now, therefore it might still be there but we can't tell for sure?

      Nah, more like pressure fusion steam cleaning. If it's crowded, the matter falling in to the black hole reaches billion of degrees, molecules breaking up, electrons ripped from atoms, nuclei fusing into new elements, before being ripped apart again by tidal forces (something like 10% of the matter is converted to energy per E=mc^2, when falling into a black hole in an accretion disk).

      And if it's not crowded enough for it to get hot, then the lone water molecules will get ripped apart by tidal forces anyway,

    So a feeding black hole is called a quasar... thanks for the *great* summary!

  • 12 billion light-years away

    Then it means there was water there 12 billion years ago. Is there any left?

  • Doesn't "reservoir" imply it's reachable, usable as a water reserve? This water was rotating a black hole 12 billion years ago, and was probably all sucked up by the hole or the water molecules ripped apart in the quasar jets by 11.999 billion years ago. I don't think "reservoir" is quite a right word here.

  • 140 trillion times all the water in the world's ocean + huge "tidal" forces from a huge, feeding black hole = KOWABUNGA DUDE!
