DWARF PLANET HAUMEA’S LUNAR SYSTEM SMALLER THAN ANTICIPATED:
Haumea, a dwarf planet on the edge of our solar
system, doesn’t have the same kind of moons
as its well-known cousin Pluto, according to
a new study. This is despite original evidence
that suggested they both formed in similar giant
impacts and adds to the mystery shrouding how
these icy bodies formed.
Haumea, named for the Hawaiian goddess
of fertility and childbirth, has two known
satellites, an unusually high spin rate, and is
also the “parent” of a large family of icy bodies
in the outer solar system that used to be chunks
of its surface, but which now orbit the Sun on
their own. These unique features are indicative
of an ancient collision and make Haumea one
of the most interesting objects in the Kuiper
Belt, said Darin Ragozzine, assistant professor
of physics and space sciences at Florida Institute
of Technology and leader of the study.
Pluto and Haumea are the only outer solar
system bodies with more than one moon. Pluto
boasts the very large Charon and four tiny
moons. The other known Kuiper Belt dwarf
planets, Eris and Makemake, have a medium
and tiny moon, respectively. Makemake’s moon
was discovered in April.
But beyond its two known medium-size
satellites, Haumea doesn’t seem to have small,
icy moons similar to Pluto’s. “While we’ve
known about Pluto’s and Haumea’s moons
for years, we now know that Haumea does not
share tiny moons like Pluto’s, increasing our
understanding of this intriguing object,” says
Ragozzine.
The observations also seem to imply that,
despite some similarities, the satellite systems
of the icy dwarf planets had different pathways
to their formation. Even with the new result,
Ragozzine emphasizes that both Pluto and
Haumea moon systems have the planetary
science community stumped. “There is no self-
consistent formation hypothesis for either set of
satellites.”
The Haumea observations were made with the
Hubble Space Telescope, which was focused on
a ten-consecutive-orbit sequence in 2010. The
hunt for extra moons around Haumea relied on
a novel technique labeled the “non-linear shift-
and-stack” method, an approach that may be
useful for other satellite searches or detecting
yet-unknown Kuiper Belt objects.
As continued analyzes of NASA New Horizons
observations of Pluto roll in, Ragozzine is
seeking funding to try to get to the bottom of
Haumea. The new understanding that the dwarf
planet doesn’t have tiny moons and exhibits
other unusual characteristics adds to the puzzle.

LEARNING ABOUT MUSHROOMS
MY AMAZING FASCINATION
WITH SUMMER
Recently, when my
“Foraging Oregon” book
was released, one person
criticized that it did not
include mushrooms in the book because “mushrooms
are part of foraging.” Obviously, the person didn’t
actually read the book, and so he missed my reasons
for not including mushrooms in the book. Yes, some
mushrooms are easily identified, like chicken of the
woods, yet there are many lesser-known related species
in the “safe” groups can cause sickness if not processed
right.
Mycology was the science that obsessed me the most,
before botany, and back in the early ‘70s, mycologists
were few and far between. Besides getting every book
on the subject, I also joined the Los Angeles Mycological
Association, and spent many weekends in fields and
wild areas looking for mushrooms, and learning how
to identify them.
Though I’ve written over a dozen books on wild
foods and self-reliance, I’ve never written a book
exclusively on mushrooms. The reason is because there
are many specialists out there who’ve already written
some excellent mycology books. I admit, I shared
some basics of mycology in my “Testing Your Outdoor
Survival Skills” book, and I’ve used my mushroom quiz
for the basis of many lectures.
My publisher of the Falcon Guides wanted me to
include a few mushrooms in my “Foraging California”
book, partly because all of the other books in that
foraging series included a few mushrooms. But I
decided not to include even a few “simple” mushrooms,
in part because there are really far too many members
of each genus than are ever included in any book, and
so amateurs really have no practical way of knowing
these “look-alikes” even exist. I still read about experts
who ate the wrong mushroom, and died, usually slow
and painfully.
Consider that there are many more good botanists
than mycologists because you can go out any day (more
or less) and study the flowering plants and trees, and
you can get to know them well. But mushrooms don’t
last so long. They appear seemingly at random, and
they disappear. There are therefore not as many good
mycologists as botanists because it takes a lot more
time and dedication to study the mostly ephemeral
mushrooms.
Also, even the best mycology books do not
include all the possible mushrooms that you might
find in an area. At one time or another, I believe
I have possessed every notable book published on
mycology. Each contains verbal descriptions, and
one or two photos. Some contain technical keys
for differentiating the mushroom you found with
every other mushroom. But if the mushroom in
your hand is not found in the book in which you
are now looking, you might be tempted to conclude
that what’s in your hand must be this one or that one
in the book. Maybe, maybe not. No harm done if
you’re just trying to identify the mushroom, and if
you don’t intend to eat it. But it’s an entirely different
ball game if you intend to eat the wild mushroom.
We’ve all heard the old rule: there are old mushroom
hunters, and there are bold mushroom hunters, but
there are no old and bold mushroom hunters. Sad, but
true.
When I was just starting out learning mycology,
I insisted on eating every mushrooms that the old
experts identified to me as being edible. Some were
good, some were not. I had at least a few unpleasant
vomiting sessions. I no longer care to try every “edible”
mushroom.
In other words, there are a LOT of mushrooms out
there, and not all of them are described in books. If
you want to eat wild mushroom, learn mycology first
(the study of mushrooms) and then learn mycophagy
second (the study of how to eat wild mushrooms).
Learn by taking a class where you will see the actual
mushrooms, hopefully in the field at least some of the
time. Join a local mushroom society where you can go
on field trips. Then, use internet sites, and videos, and
books as the back up to your direct field experience.
BOOKS
And yes, there are some really good books out there.
Here are just a few of the books that I highly
recommend for those of you who choose to pursue the
science of mycology, without losing your life:
“California Mushrooms: The Comprehensive
Identification Guide,” by Desjardin, Wood, and Stevens
(Timber Press, 2015). This new book is expensive,
hard-cover, all color photos, up-to-date, and useful well
beyond just California. You get a good comprehensive
overview of the world of mycology, with all the types
of fungi broken into their categories with keys to help
you identify the mushroom in hand. Well worth the
money. This over-sized book is over 550 pages.
“Mushrooms Demystified,” by David Arora (Ten
Speed Press, 1986). David Arora is perhaps the man
when it comes to mycology. A thick book with 2000
species, over 800 photos, mostly black and white but
many in color. If this is the only book you had, you’d
do well, and you’d learn that patience is part of studying
mycology. Nearly 1000 pages.
“The Great Encyclopedia of Mushrooms” by
Lamaison and Polese (Konemann, 2005). This is an
English version of a German original, really more of
a coffee table book that is a very good introduction
to mycology. A very good pictorial overview, and
if you master this, you’re ready for one of the other
books.
“The Mushroom Manual” by Pearson
(Naturegraph, 2014) Both amateurs and
professionals will enjoy this book. It does not
purport to tell you everything you ever wanted to
know about mushrooms. It does, however, give the
reader an excellent overview of fungi. It includes the
“foolproof four” that anyone can identify and eat,
the fatal five (deadly mushrooms), the nine basic
groups, and mushroom identification keys.
It comes as a great relief to me that winter is
over and summer has stepped up and taken
its rightful place. I really love summer. I am
fascinated with all aspects associated with
summer.
Some people, like the Gracious Mistress of
the Parsonage, enjoy the aspects of winter,
primarily the cold. I just do not like the cold.
I will accept a cold shoulder occasionally, but
that is as far as I will go in the area cold.
Winter has no aspects of fascination for me.
I do not like being cold, shivering and my nose
tingling with frostbite. Winter is certainly not
for me.
During the wintertime, I have to wear all
kinds of clothing and coats and sweaters. In
the summer time, I can relax, sit on the back
porch with a glass of iced tea and enjoy the
butterflies floating through the flowers. Ah,
what a wonderful time summer is.
This brings up the sharp difference between
my wife and me. For some reason she loves
winter. This may have something to do with
her growing up in upper state New York where
it is snowy and wintry all the time. I remember
visiting once in August and just about froze to
death.
But she enjoys chilly temperatures. She
enjoys when the temperature falls below 70.
I have a basic rule in life. When the
temperature falls below my age, I’m cold. Each
year it seems to be getting a little higher.
The thing about summer is simply this; when
it gets really, really hot, I simply turn on the air
conditioner, which truly works. Not so much
in the winter. No matter how cold it is I cannot
seem to get the temperature high enough to
ward off that chilly, frosty feeling.
I know in the middle of winter we have a
holiday called “Christmas.” Have you ever
noticed how Santa Claus dresses?
He is extremely overweight, all that
insulation under his skin, plus he wears a huge
red coat with a hat. Most of the time he is also
wearing gloves. If he really enjoyed winter, he
would experience winter in the beauty of its
rawness.
However, summer for me has many
amenities. For example, you can tell your wife
that you are going fishing and never actually
get to the lake to do any fishing. Along the way,
you see a nice area where people are having
picnics and just sitting under some lovely trees.
Basking in the sunlight of summer is worth all
that it is made up to be.
Summer is also the time for picnics.
It begins with Memorial Day, which is the
first picnic day of the summer. From then on
there is a picnic day set for every month of the
summer. In fact, in July, I make sure there are
two picnic days just in case I miss the first one.
The beautiful thing about a picnic is you can
eat with your fingers. In the house, the wife
wants me to eat with forks and spoons and all
of that kitchenware stuff. Out on the picnic
table I can eat as I am supposed to eat: with my
fingers.
Summer is the time to chill out. During the
winter you are running here and there and
trying to catch up with this holiday and that
holiday. Summer is the time to slow down and
enjoy the sunshine.
I am not sure why there are more holidays
throughout the winter than there are during
the summer, but I sure am grateful for the
person who set up that calendar. Summer is
not celebrating this holiday and that holiday;
summer is enjoying the outdoors as much as
possible.
Just the other day I was heading out the door
and the wife called after me and said, “Where
are you going?”
I thought about that for a moment, smiled
and said, “I don’t know where I’m going.”
There was a slight pause and then she said,
“Can I go with you?”
The beautiful thing about summer is that you
can go somewhere without going anywhere.
Nothing is more pleasant than having nowhere
to go and taking your time getting there.
If I had anything to do with it, and I certainly
don’t, I would make sure there would be
summer the year round. I will never, ever get
tired of the summer time.
Sitting on the porch one afternoon the wife
came out and said, “What are you doing? Don’t
you have something to do?”
I rocked back and forth three times without
even looking at her and said, “I’m doing
nothing and liking every moment of it.”
She then joined me in doing nothing and we
did nothing for the rest of the afternoon. I had
things to do. She, of course, had things to do.
But we just joined our hearts in doing nothing
together. Nothing is better than a summer
afternoon when you can do nothing together
and enjoy every moment of it.
I like with the preacher said, “I said in mine
heart, God shall judge the righteous and the
wicked: for there is a time there for every
purpose and for every work” (Ecclesiastes
3:17).
If there is a time for work, then there should
be plenty of time for rest. If I don’t get my rest,
how can I do the work that I have to do?
