Zim (software) Some of the editing features supported: Lightweight text mark-upBullet-lists and check-listsLinks to other pagesRevision control systemCompilation of the notes into a webpage Zim supports several plugins, including: Equations (using LaTex and dvipng)Plots (using GNU R or Gnuplot)Spell checking (using gtkspell)Diagrams (using Graphviz) The core features of Zim depend on python, gtk and python-gtk modules and thus Zim can be easily ported to any platform where these modules are available. Hold On For This One: The Moon Is Hollow And This Is Why Have you ever stopped to think about our moon? Evidence describes an alternative story for its origin. Get ready for this one. “What in blazes is our Moon doing way out there? It’s too far out to be a true satellite of Earth , it is too big to have been captured by the Earth. The chances of such a capture having been effected and the Moon then having taken up a nearly circular orbit about the Earth are too small to make such an eventuality credible. . . .

Dawn Captures Sharper Images of Ceres Craters and mysterious bright spots are beginning to pop out in the latest images of Ceres from NASA's Dawn spacecraft. These images, taken Feb. 12 at a distance of 52,000 miles (83,000 kilometers) from the dwarf planet, pose intriguing questions for the science team to explore as the spacecraft nears its destination. The image is available at: "As we slowly approach the stage, our eyes transfixed on Ceres and her planetary dance, we find she has beguiled us but left us none the wiser," said Chris Russell, principal investigator of the Dawn mission, based at UCLA. "We expected to be surprised; we did not expect to be this puzzled." Dawn will be gently captured into orbit around Ceres on March 6.

Soyuz console Fighter jet and spaceship cockpits seem to fascinate me and that of the Soyuz is no exception; unfortunately there are no detailed diagrams or manuals publically-available on the Internet that I know of! The following diagrams are ones I have collected from various places, and are the best I can do at the moment. The Soyuz TM Information Display System is called the “Neptune”, «Нептун»; for the TMA it is the Neptune ME. Some of the buttons and controls on the console can’t be reached without a stick to poke at them! The stick is called Указател, Ukazatel, “Pointer”.

NASA: Huge solar flare may disrupt power and communications By Agence France-PresseTuesday, June 7, 2011 18:13 EDT WASHINGTON — An unusual solar flare observed by a NASA space observatory on Tuesday could cause some disruptions to satellite communications and power on Earth over the next day or so, officials said. The potent blast from the Sun unleashed a firestorm of radiation on a level not witnessed since 2006, and will likely lead to moderate geomagnetic storm activity by Wednesday, according to the National Weather Service. “This one was rather dramatic,” said Bill Murtagh, program coordinator at the NWS’s Space Weather Prediction Center, describing the M-2 (medium-sized) solar flare that peaked at 1:41 am Eastern time in the United States, or 0541 GMT. “We saw the initial flare occurring and it wasn’t that big but then the eruption associated with it — we got energy particle radiation flowing in and we got a big coronal mass injection,” he said. “You can see all the materials blasting up from the Sun so it is quite fantastic to look at.”

I used to be undecided, but now I'm not so sure. VUE stands for Visual Understanding Environment. This program comes from Tufts University in the USA. It was written to allow students to take notes during lectures and to make presentations. The program stores its maps in disk files which have to be saved manually. I have not used VUE as a presentation tool and so maybe I have a biased opinion. To do a presentation with VUE you first have to define a ‘path’, this is a series of slides.

Playbook — Asteroid Day Organising a regional event Asteroid Day aims for global grassroots involvement. Regionally organised events will be held June 30 that will tap into centralised online feeds of live expert lectures, and educational programs from international Asteroid Day organisers. Whether you run a museum, an astronomy club, or are simply a concerned citizen, this issue impacts us all, and Asteroid Day is designed to help you facilitate a conversation in your community. Some ideas include hosting panel discussions, dinners, educational events, concerts, film screenings, and myriad online activities to share information and connect. Daytime observing sessions of the Sun and nighttime viewing of the planets and stars create other opportunities.

Videos: Delta 4-Heavy and Orion prepared for launch Delta 4-Heavy processing — CBC mate Inside the Horizontal Integration Facility, the three Common Booster Cores for the Delta 4-Heavy rocket to launch Orion on Exploration Flight Test No. 1 are mated together. Delta 4-Heavy processing — second stage mate The Sounds of Pulsars A pulsar is a highly magnetised neutron star, with a radius of 10-15 km, having somewhat greater mass than the Sun which has a radius of approximately 1 million km. Radiation is beamed out along the magnetic poles and pulses of radiation are received as the beam crosses the Earth, in the same manner as the beam from a lighthouse causes flashes. Being enormous cosmic flywheels with a tick attached, they make some of the best clocks known to mankind.

Time Machine A METEOR SHOWER IN BROAD DAYLIGHT: The annual Arietid meteor shower peaks this week on June 7th and 8th. The Arietids are unusual because they are daytime meteors; the shower is most intense after sunrise. People who wake up early might notice a small number of Arietids during the dark hours before dawn. The real action, however, occurs in broad daylight. Tune into the meteor radar for echoes. M-FLARE AND RADIATION STORM: This morning around 0641 UT, magnetic fields above sunspot complex 1226-1227 became unstable and erupted. How Does Calais Work?

In 2002 the British newspaper The Sunday Telegraph reported that the Vatican had banned the veneration of those angels who do not appear in the authorised texts of the Bible. This was an attempt to counter the influence of unnamed New Age groups who were allegedly recruiting new members within the Roman Catholic Church. In future, prayers were only to be directed to the three archangels Michael, Gabriel and Raphael who are mentioned in the Bible.
