SCIENTISTS AT KECK OBSERVATORY DISCOVER THE FLUFFIEST GALAXIES
An international team of researchers led by Pieter
van Dokkum of Yale University has used the W.
M. Keck Observatory to confirm the existence of
the most diffuse class of galaxies known in the
universe. These “fluffiest galaxies” are nearly as
wide as our own Milky Way galaxy—about 60,000
light-years—yet harbor only one percent as many
stars. The findings were recently published in the
Astrophysical Journal Letters.
“If the Milky Way is a sea of stars, then these
newly discovered galaxies are like wisps of clouds,”
said van Dokkum. “We are beginning to form some
ideas about how they were born and it’s remarkable
they have survived at all. They are found in a dense,
violent region of space filled with dark matter and
galaxies whizzing around, so we think they must
be cloaked in their
own invisible dark
matter ‘shields’
that are protecting
them from this
intergalactic
assault.”
The team
made the latest
discovery by
combining results
from one of the
world’s smallest
telescopes as well
as the largest
telescope on Earth.
The Dragonfly
Telephoto
Array used
14-centimeter
state of the art
telephoto lens
cameras to
produce digital
images of the
very faint, diffuse
objects. Keck
Observatory’s
10-meter Keck I
telescope, with its
Low Resolution
Imaging
Spectrograph,
then separated the
light of one of the
objects into colors
that diagnose its
composition and
distance.
Finding the distance was the clinching evidence.
The data from Keck Observatory showed the
diffuse “blobs” are very large and very far away,
about 300 million light-years, rather than small
and close by. The blobs can now safely be called
Ultra Diffuse Galaxies (UDGs).
“If there are any aliens living on a planet in an
ultra-diffuse galaxy, they would have no band of
light across the sky, like our own Milky Way, to
tell them they were living in a galaxy. The night
sky would be much emptier of stars,” said team
member Aaron Romanowsky, of San Jose State
University.
The UDGs were found in an area of the sky called
the Coma cluster, where thousands of galaxies have
been drawn together in a mutual gravitational
dance. “Our fluffy objects add to the great diversity
of galaxies that were previously known, from giant
ellipticals that outshine the Milky Way, to ultra
compact dwarfs,” said University of California,
Santa Cruz Professor Jean Brodie.
“The big challenge now is to figure out where
these mysterious objects came from,” said Roberto
Abraham, of the University of Toronto. “Are they
‘failed galaxies’ that started off well and then ran
out of gas? Were they once normal galaxies that got
knocked around so much inside the Coma cluster
that they puffed up? Or are they bits of galaxies that
were pulled off and then got lost in space?”
The key next step in understanding UDGs is
to pin down exactly how much dark matter they
have. Making this measurement will be even more
challenging than the latest work.
The W. M. Keck Observatory is located near the
summit of Maunakea on the island of Hawaii. Its
two, 10-meter optical/infrared telescopes feature a
suite of advanced instruments including imagers,
multi-object spectrographs, high-resolution
spectrographs, integral-field spectrographs and
world-leading laser guide star adaptive optics
systems.
Keck Observatory is a private 501(c) 3 non-profit
organization and a scientific partnership of the
California Institute of Technology, the University
of California, and NASA.

WATER RECYCLING RETROFITTING

THOSE MAGNIFICENT MAY FLOWERS
During California’s drought of
the late 1970s, I helped many
people disconnect their water
lines from the city’s sewer line so
their waste water (minus the toilet) could go into their
yards, thereby using that water at least twice.
I mostly worked with Timothy Hall of the non-profit
WTI, because he knew more about plumbing than I did
at the time. We began by disconnecting a bathtub drain
pipe from the sewer line of the non-profit’s facility. It
didn’t take much time to disconnect the drain from
under the bathtub, but we did have to crawl under the
house in the narrow crawl space, getting covered with
cobwebs and this very fine decomposed granite that
stained our clothes and didn’t wash out. Then, we used
old recycled galvanized pipes and connected the pieces
until we had a line going all the way down hill about
100 feet away to where trees would be planted for an
orchard.
We advertised as “ecology plumbers” who would go to
your home and retrofit your sink or bathtub drain so
the water would go outside. We knew this was illegal
according to the Building and Safety codes of the City
of Los Angeles, but there was also a drought during this
time, and people wanted to get as much use out of their
water as possible. Timothy and I did a half-dozen or
so of these jobs at a fair price, much to the delight of
renters and home-owners.
The City of Los Angeles representatives made a lot of
noise about the people saving water and using less.
The news notices of the day talked about a lot of very
standard ways to save water: turn off the water when
brushing teeth, water your yard at night, plant drought-
tolerant plants, use lots of mulch, don’t wash off the
sidewalk, use a full load when you wash clothes, etc.
But through my work with Timothy and with WTI, we
went way beyond those very basic ways to save water.
And we taught others how to do likewise.
For example, we advocated in the 1970s against having
a front lawn, one of the biggest and pointless water
wastes in the entire country. We collected rain water
in our own low-tech way. We washed a few items of
clothes every time we took a bath. And we altered our
own plumbing so that the kitchen and bathtub water
could flow right outside into the garden. And it turned
out that this last method – known today as “grey
water recycling” – was then, and might still be, illegal
according to the Department of Building and Safety
of the City of Los Angeles. The rationale for this being
illegal is that everyone has their own way of doing it and
some folks are less careful than others. The city didn’t
want pools of water outside homes and apartments
which raise mosquitoes and possibly attract rats or
roaches or worse.
Still, we focused on kitchen sink and bathtub water,
and we only did it where it could be done easily by
gravity and where it would not be a problem. In one
case, we disconnected the drain from under a second-
story kitchen sink, and attached a PVC drain pipe that
had to go through the wall to the outside. We had to
drill an appropriate sized hole, and then we attached
the hardware to it which would allow the owner to
screw on a garden hose. The garden hose was then
moved around as needed by the homeowner so that the
water would flow under fruit trees, ornamentals, or the
garden.
We advised the customers that they should only buy dish
soaps that contained no dyes or perfumes. Phosphates
weren’t a big issue, as they are when your detergents
flow into the Los Angeles County sewer system, and
eventually flows out to the ocean. Phosphates in the soil
act as a fertilizer. Timothy and I were delighted to do
some part-time work that we enjoyed, and we felt made
a difference in the world. Furthermore, for a few hours
work, I would earn close to $50, which made me think I
was pretty close to a millionaire for a day.
Also, since I had potted plants and a little nursery
just outside the kitchen door, I would simply take
the plastic dish pan when done washing dishing, and
empty the water onto the plants. This is probably one
of the easiest ways to recycle household water with no
cost of retrofitting. It is really a no-brainer – even my
mother did that consistently at her Pasadena home, and
would yell at me and my brothers if we did not do so.
“Why are you so lazy?” she’d chide us. “Take that water
outside and water the roses!”
Later, in another home, I did the same thing with the
washing machine, and kitchen, but not the bathtub
because there was no way to use gravity for the water
to flow outside. Still later, at a house I rented, I sent all
the kitchen and bathwater out into the yard. I mulched
heavily and would often toss seeds right out the kitchen
window. When I finally left this little cabin in Altadena,
a 15 foot avocado tree had grown in about 5 years from
one of my seeds that I’d tossed out the window, and was
producing fruit with no grafting.
It made sense then, and it makes sense now, to recycle
all one’s water. And despite all the smiley talk and
encouragement from the folks at city hall, the right
hand of the city does not always agree with the left
hand. If and when Building and Safety finds out you are
doing “illegal” greywater recycling, you’ll be cited and
asked to hook back up to the sewer. The alternative is
to buy the pumps and holding tanks they now require
for this, and the expensive permit, upwards of about
$10,000. And that price means that anyone smart will
simply not talk to city hall, but find ways to “go green”
safely and inexpensively.
Perhaps today because there are more and more of us
residing on smaller and smaller parcels of land, many
of the simple and common-sense things that we just did
with no regard for any government dictates or rules is
not as possible today. This isn’t because it’s not a good
idea, but rather because not everyone takes the time to
recycle and to compost in a way that is hygienic and
sightly.
Whatever the argument, I still believe that the simplest
path is the best, and that the most natural course
of action is the most ideal for the most people. That
which has worked for millennia should still work as
long as people are willing to slow down, and quit their
blind faith in a technological god that they think will
miraculously save us.
The Gracious Mistress of the Parsonage and I
were sitting on the back porch admiring the
close of the day. Nothing is more relaxing
than sitting together drinking coffee, glad
that another day has quietly slipped by.
Out of the clear blue sky my wife said,
“Aren’t those flowers just magnificent?”
I grunted a little grunt of satisfaction to
which she replied, “Which do you like? The
roses or the tulips?”
Now I was in a bit of a predicament. I hate
it when I get into a predicament, which is
usually not my doing. I like to get along with
people and just agree with them. What I hate
is when people ask me a question and I really
do not have an answer.
As to, which flower I liked, I really do not
know the difference between a rose and a tulip.
To me a flower is either yellow or blue. That is
the only different kinds of flowers I know. But
not so with my gardening connoisseur wife.
Every flower has a name and you had better
give it the right name.
As far as I am concerned, a flower is a
flower. The purpose of a flower is to enjoy it;
enjoy its look and its fragrance. All I can say
about a flower is, “That’s a pretty flower.”
This certainly is not acceptable to my wife.
Every flower must be treated with the dignity
they have earned.
When it comes to flowers, especially the
flowers in our backyard, my wife knows them
all by name and their history from the time
they were but a humble seed put into the
ground. Personally, I do not have the time to
invest in something like that. I find it strange
talking to a flower. Talking to nuts, maybe, but
not a flower.
“You should learn to appreciate flowers,
especially the flowers in May.” At this point,
I realized that I was in for conversation on
flowers, whether I wanted to converse on
flowers or not. Since I am a well-seasoned
husband, I knew I just had to buckle down
and endure it until it passed by.
One of my favorite Scripture is, “This too
shall pass.”
“Don’t you remember what you were doing
in April?”
Her question caught me by surprise. I was
not quite sure what April had to do with
flowers in our backyard, but I was about to
find out.
“Don’t you remember that in April you
were complaining about all the rain?” She said
it rather sarcastically and I knew there was a
point somewhere, but I was not getting it at
this time. I did remember complaining about
the rain.
It seems strange that every time I want to
do something outside, particularly in the
month of April, I no sooner get outside then it
starts to rain. I know we need rain. Why can’t
it rain at night when I am catching some Z’s?
That is what I would like to know. Why does
rain have to inconvenience me?
If I plan for some indoor activity, it never
rains. If I plan for something outside it always
rains. I am getting a little paranoid at this. I
knew in a moment my wife would straighten
me out on this one.
“Remember that little rhyme that goes,
‘April showers bring May flowers’? We have
these marvelous flowers in the month of May
because of the rain in April. I think you need
to begin to appreciate the rain because of what
it brings about.”
Well, I did remember that old rhyme from
school days. I just never put any kind of
practicality to that sort of thing. It is not that
I do not like poetry; I just do not understand
poetry. And, just to set the record straight, I
have written my share of poetry. However,
poetry, especially my poetry, does not have
anything to do with real life.
My mind was soon to be changed. I got
a lecture on the whole dimension of April
showers and the effect on the May flowers. I
only wish I had a recording of that because I
could put it online and let everybody know
about this.
When my wife went into the house to get
some coffee, I had a moment to muse on that
whole “April shower” bringing “May flower”
idea. I must admit, there is something to it.
When I am going through a very difficult
time, I sometimes wonder what in the world is
the purpose of it all? I would like to go through
life without any difficulties whatsoever. But,
just like those “April showers,” the difficulties
in life have a purpose down the road a bit.
The trials of life have a purpose that may
not be evident at the time, but given enough
time, those “April showers” will bring some of
those marvelous “May flowers.” This should
encourage me in particular to appreciative
the difficulties in my life. They are not there
arbitrarily.
James understood this when he wrote, “My
brethren, count it all joy when ye fall into
divers temptations; Knowing this, that the
trying of your faith worketh patience. But let
patience have her perfect work, that ye may be
perfect and entire, wanting nothing” (James
1:2-4).
When my wife came back with the fresh
coffee, I said to her, “Your May flowers are
simply spectacular.” She smiled, then nodded
and just looked at her May flowers.
