March meteor lands in Norway

A meteorite crashed through the roof of a family’s shed in Oslo, Norway, on March 12. It weighed 585 grams, which split into two pieces, and probably originated from a meteorite seen over Norway on March 1. Although not rare, it is unusual for a fragment to land on people’s property. The fragment is called a ‘breccia’ which is a rock composed of broken pieces or cemented together.

The last time a major piece of a meteorite landed in Norway was on June 9, 2006, when one crashed into the side of a mountain near Troms and Finnmark, believed to be of a considerable mass. Its impact could be heard and felt. NORSAR, the geophysics and seismology research foundation at Karasjok, registered its seismic tremor. Previously in Norway, a large meteorite impacted Alta in 1904, weighing 90 kilograms (198 pounds).

In south-eastern Australia, a meteorite landed through the roof of farmer’s hay shed on September 28, 1969 in the town of Murchison in the state of Victoria. A disintegrating comet left 100 kilogram meteoric rocks on the farmer’s property. Called the Murchison meteor, or Murchison rocks, were found to contain amino acids—the carbon compounds known to be the building blocks for life.

The acacia thorn trees of Kenya

There are nearly 800 species of acacia trees in the world, and most don’t have thorns. The famous "whistling thorn tree" and the Umbrella Thorn tree of Kenya are species of acacia that do have thorns, or spines. Giraffes and other herbivores normally eat thorny acacia foliage, but leave the whistling thorn alone. Usually spines are no deterrent to giraffes. Their long tongues are adapted to strip the leaves from the branches despite the thorns. The thorny acacia like dry and hot conditions. The thorns typically occur in pairs and are 5-8 centimetres (2-3 inches) long. Spines can be straight or curved depending on the species.

Sister cities discussed: Canberra and Islamabad

Two months ago, in March 2015, Australia and Pakistan agreed to explore ways to deepen ties. The relationship between Australia and Pakistan has been strong for decades, and the two countries continue to keep dialogues open. The annual bilateral discussions were held in Australia in March to continue engagements on a wide range of matters of mutual interest. The Pakistan delegation discussed points of interest will include sports, agriculture, economic growth, trade, border protection, business, and education.

Canberra currently has international Sister City relationships with Beijing in China and Nara in Japan. One example of existing...
