Congratulations to Tom Lowe who wins the title Astronomy Photographer of the Year 2010 with this spectacular image of ancient trees silhouetted against the bright star clouds of the Milky Way. Competition judge Marek Kukula says: ‘I think this beautiful picture perfectly captures the spirit of Astronomy Photographer of the Year, linking the awe-inspiring vista of the night sky with life here on Earth. The bristlecone pines in the foreground can live as long as five thousand years. But they are babies compared to the starlight shining behind them, some of which began its journey towards us almost 30,000 years ago.

Shuttle se moer gestrip! Moer nou weg! NASA soek moer!
Discovery attachment to tank delayed by nut problem

Engineers attaching the shuttle Discovery to its external fuel tank ran into problems Friday when an internal nut used to attach a separation bolt to the belly of the orbiter slipped out of position. Re-positioning the mis-aligned nut will require access to the shuttle's aft engine compartment, sources said, but it was not immediately clear what might be required to provide that access with Discovery not yet firmly attached to its external tank.

Tiny rock-eating microbes could mine precious extraterrestrial resources from Mars
and pave the way for the first human colonists. Just don't expect them to transform
the red planet's surface into a new Earth on a short deadline, researchers say.

Space station cargo vessel blasts off
A robotic Russian resupply ship to service the International Space Station successfully launched atop a Soyuz rocket rocket today at 6:22 a.m. EDT (1022 GMT) from the Baikonur Cosmodrome in Kazakhstan. The freighter is carrying two-and-a-half tons of cargo, food and water for the high-flying laboratory.

Two Asteroids To Pass By Earth Wednesday (Today)
Two small asteroids in unrelated orbits will pass
within the moon's distance of Earth on Wed.
Both should be observable with moderate-sized
amateur telescopes.

Two asteroids, several meters in diameter and in unrelated orbits, will pass within the moon's distance of Earth on Wednesday, Sept. 8.
Both asteroids should be observable near closest approach to Earth with moderate-sized amateur telescopes
. Neither of these objects has a chance of hitting Earth.

11 September 2010 - Occultation of Venus by the moon on your doorstep
Re Post with extra information
Maak `n knoop in jou selfoon om hierdie okkultasie van Venus deur die maan nie mis te loop nie. Dit is in die dag en sal maklik met `n verkyker waargeneem kan word. Selfs met die blote oog. Venus verdwyn Saterdag 11 September om 14:29 agter die maan en verskyn dan weer om 15:47. Die sekelmaantjie gaan hoog in die hemel sit en daardie klein ligpuntjie naby hom is Venus. Sien onder vir meer spesifieke tye.
