The latter is the least well known of the four and was recentlythe object of an international observation campaignwhich was able to establish its main physicalcharacteristics. The study, led by astronomers fromthe Institute of Astrophysics of Andalusia (IAA) in Granada, Spain, and published in the journalNature, reveals the presence of a ring around theplanet. Trans-neptunian objects are difficult to studybecause of their small size, their low brightness, and the enormous distances that separate us fromthem. A very efficient but complex method lies inthe study of stellar occultations, or the passing ofthese objects in front of a star. It allows astronomersto determine the main physical characteristics ofan object (size, shape, and density) and has beensuccessfully applied to dwarf planets Pluto, Eris andMakemake. “We predicted that Haumea would pass infront of a star on the 21st of January 2017, andtwelve telescopes from ten different Europeanobservatories converged on the phenomenon,” saysJosé Luis Ortiz, researcher at IAA in charge of thestudy. “This allowed us to reconstruct with a veryhigh precision the shape and size of Haumea, anddiscover to our surprise that it is considerably biggerand less reflecting than was previously believed. It isalso much less dense than previously thought.” Haumea is an interesting object: it rotates aroundthe Sun in an elliptic orbit which takes it 284 yearsto complete (it presently lies fifty times further fromthe Sun than the Earth), and it takes 3.9 hours torotate around its axis. This rotational speed causesit to flatten out, giving it an ellipsoid shape similarto a rugby ball. The recently published data reveal that Haumea measures about 1,400 miles in its largest axis—almost the same as Pluto—but lacksthe global atmosphere that Pluto has. “One of the most interesting and unexpectedfindings was the discovery of a ring aroundHaumea. Until a few years ago we only knew of theexistence of rings around the giant planets; then, recently, our team discovered that two small bodies CHRISTOPHER Nyerges VISITING WITH KIWANIS, SIERRA MADRE [Nyerges has been teaching survival and self-reliance classes since 1974.

I spent an enjoyable lunch this last week giving a short talk to the Sierra Madre Kiwanis Club. This is a Club that was incorporated way back in 1927, 90 years of serving the community. Between bites of delicious mashed potatoes and coleslaw, I was able to share a brief overview of the work I do, and my vision for the future. I began with my teenage roots of hiking and backpacking, and disliking having to carry heavy canned goods to my destinations. Gradually, I learned to travel light with dried foods, but I also began to study the ethnobotany of our geographical ancestors, the Native peoples who resided throughout the local mountains and valleys before the Spanish invasion. The foods are still with us, though the native plants have fewer and fewer places to grow as a growing population ever-pushes for more development of homes and roads. Still, the useful native plants can be found if you take the time to look. In addition, the overwhelming majority of the so-called weeds in people’s yards are introduced plants from Europe, the majority of which are good foods or medicines. One Kiwanis member asked me to tell him that’s an unrealistic expectation. I explained to what key poisonous plant he should watch out for. the good-natured Kiwanis group that a U.N. study I told him that if he intended to begin collecting indicated that everyone needs about 11.2 gallons of foods from the wild that all he needed to know water daily for all health and hygiene issues. That is was the identity of the plant he was eating. He contrasted with the average residential American never needs to know a single poisonous plant, but using about 80 gallons a day, and the average must absolutely know the identity of any plants he L.A.
