Space Dust Monday


Astronomers hate dust as much as the rest of us ― even more, perhaps. It’s one thing to get a little dust in your eye that takes your vision out of focus. Now imagine this kind of dust problem on a galactic scale where it hinders scientists trying to focus their telescopes into space.

That’s part of the challenge faced by researchers at the Lawrence Berkeley National Laboratory in California, reports They’re creating an instrument that will offer specific information on how fast the universe is growing.

This device ― the Dark Energy Spectroscopic Instrument ― will create a map of over 30 million galaxies. But in order for that map to be precise, astronomers will have to correct for the problems created by all the dust particles in the Milky Way galaxy that impede their deep space investigations.

“Because outer space is a very dusty place, that makes things very difficult for astronomers and astrophysicists who are trying to peer farther across the universe or deep into the center of our own galaxy to learn more about their structure, formation and evolution,” according to a Berkeley Lab statement.

To help with the DESI project, Berkeley researchers created the following detailed 3D animation showing dust that spans thousands of light-years in our home galaxy. The study was published this week in The Astrophysical Journal. Here’s the animation:

    Alright, who’s in charge of dusting off the Universe? Slackers no doubt judging from the amount of dust accumulation in this place.

    Here @ DWF we always keep the place clean and dust free cuz dust makes a mess combined with spilled coffee and beer, mud.

      We have wet vacuums, little robot things, to put on the floor of our swimming pools.
      There are wandering vacuums one can get for their homes, let them roam.

      I often wish there were more people making machines to clean the debris out of our oceans and rivers. I saw a documentary that had a story about that in it. I watched the machine/boat that did the work, and how it worked.

      Man could make a similar waste-scooper for outer space. It could just mosey around, scooping up junk, and maybe the dirt.

    Up B Street, along Spokane Street to the sidewalk down to downtown, specifically The Foundry took 26 minutes. Place is packed on a Monday night.
