New
magazine for Australian astronomers, both beginning and advanced:
The publishers of the well-known American magazine 'Sky & Telescope' now produce a similar magazine for the benefit of Australian amateur astronomers and star-gazers. Called 'Australian Sky & Telescope'. Averaging about 100 full-colour pages, its sections are entitled 'News & features', 'Observing & exploring', 'Products & reviews', and 'Activities & people'. There is also a main cover story, which in the first issue investigates how planetary systems form and evolve. The magazine's format is very similar to that of the American version, although it contains a little more humour sprinkled through its pages. This is probably because it is staffed and substantially written by Aussies, and printed here under licence from its American counterpart. Definite bonuses in the Australian version are the coverage of local events (such as the reopening of Mount Stromlo Observatory and a report on Queensland's Astrofest held last August), illustrated reports on the work of local people, the sky descriptions and charts are correct for us, and the advertisers are mostly Australian firms. Click here to access the website of 'Australian Sky & Telescope'.
The Australian magazine 'Sky and Space' and the American 'Astronomy' are also highly recommended.
Interesting research news (latest news first):
Giant telescopes damaged by earthquake in Hawaii: Two powerful earthquakes of magnitudes 6.7 and 6.0 struck the island of Hawaii seven minutes apart on the morning of Sunday, October 15 last. These caused significant damage to the large observatories located on the summit of Mauna Kea. Observatory buildings received superficial damage, and electrical power fluctuations and outages caused problems for sensitive equipment. Because of their location at the top of a dormant volcano, most telescopes are fitted with earthquake restraints to protect them from seismic events. These performed as planned, but some damage did occur:: This is home to Keck I and Keck II, the two largest telescopes in the world with mirrors 10 metres across. Keck I was moved horizontally 25 mm, the largest displacement of any of the telescopes, but was unharmed otherwise. Keck II has had two seriously damaged radial pad supports and seismic restraint brackets replaced. Keck II requires additional engineering tests before it can begin on-sky tests.: The 3.6 metre optical/infrared telescope collided with its earthquake restraints, which were bent as they were designed to. The horseshoe mount was deformed slightly, and the right ascension decoder smashed. During repairs, it was found that, although the gearing and hydraulic systems were operating normally, the replacement decoder had to be placed in a slightly different position. Subsequent testing revealed a problem with tracking at certain hour angles. This was traced to a dent in the horseshoe mounting that will need to be repaired before the telescope can achieve its previous pointing accuracy. The observatory dome also was displaced during the earthquake.: The observatory was moved, the telescope engaged its earthquake restraints, and some debris fell on the 8 metre primary mirror, fortunately without harming it. The worst damage was a broken ceramic rod in the secondary mirror system at the top end of the telescope. The rod, about 24 cm long and 25mm in diameter, broke cleanly so engineers were able to successfully glue it back together with epoxy. The rod is one of three used in the secondary mirror assembly. In addition, a new precision position sensor was installed in the system to replace a sensor damaged by the earthquake.: The 8.2 metre telescope suffered no major damage, but its pointing accuracy and tracking were found to be not as good as they were before the earthquake. Three weeks of testing revealed that an encoder unit that measures the rotation of the telescope had shifted. Realignment of the encoder and the telescope have restored the pre-earthquake precision.

Dateline - 8 February 2010: Large sunspot appears
The sudden emergence of big sunspot 1045 over the weekend has caused a sharp increase in solar activity. The active region has produced three M-class and almost a dozen C-class solar flares since it appeared on Saturday. The strongest blast, an M6-class eruption on February 7, may have hurled a coronal mass ejection toward Earth. High-latitude sky watchers should be alert for auroras in the nights ahead as a result of this activity. Also, ham radio operators are picking up strong solar radio bursts using shortwave receivers. Sample sounds and images may be found here ..

With his wife Margaret, Dr Burbidge is credited with having a profound influence in the development of modern astrophysics and cosmology, the metaphysical study of the origin and nature of the universe. In the 1950s he and his wife were among the astronomers breaking new ground in the field of creation of elements (nucleosynthesis) inside stars. He also had a reputation as a contrarian for his stance rejecting the big-bang theory, which states that the universe originated from a single point of infinite energy that exploded in a fireball of creation.

Dateline - 14 January 2010: NASA's James Webb Space Telescope will join the search for exoplanets
NASA's next great observatory, the James Webb Space Telescope, is designed to study stars and galaxies. With a mirror made up of 18 hexagonal segments totalling a collecting area of 25 square metres, the telescope will work at infrared wavelengths. It is due to be launched in 2014. Astronomers are beginning to realise, however, that Webb will make a great planet hunter too.
"Webb was originally conceived to search for the first galaxies and address the big cosmological questions associated with them, but we now know it can contribute powerfully to the planet hunt," says Mark Clampin of NASA's Goddard Space Flight Centre. "Exoplanets are tremendously exciting. The field is changing literally by the day. I gave a talk on exoplanets the other day, and in the time between writing and delivering the speech, astronomers announced 30 new planets!" Full story

Dateline - 6 January 2010: Hubble space telescope photographs oldest galaxies yet
The refurbished Hubble Space Telescope has set a new distance record by discovering the oldest galaxies ever seen, dating back 13 billion years, or 600-800 million years after the Big Bang. The never-seen-before galaxies are keys to interpreting the development of the first stars and the formation of the first galaxies that later evolved into the elliptical galaxies like our own Milky Way that now populate the universe.The age and masses of the galaxies were calculated by combining new data from Hubble (the first space telescope was refurbished by a shuttle mission last May) and images from NASA's Spitzer Space Telescope. The galaxies are small, only one-hundredth the size of the Milky Way. More Picture These two links contributed by Gary Taylor.

Dateline - 31 December 2009: Blue Moon eclipse
The second Full Moon for December will occur at 19:13 hrs Universal Time on December 31. This will therefore be a 'Blue Moon' for everyone west of Israel. In Queensland, the Full Moon will not occur until 5:13 hours on January 1, 2010, so it won't be 'blue' for us. In America, Europe and Africa, for the first time in almost 20 years there's going to be a 'Blue Moon' on New Year's Eve. In Europe, sky watchers will witness an even rarer event - an eclipse of a Blue Moon on New Year's Eve. What are the odds? Probabilities and observing tips may be found here.
In Australia, we will have a Full Moon on January 1 and another on January 30. With two Full Moons in the same month, the second one will be 'blue'. It is important to know that the normal colour of the Moon will not change. The lunar eclipse of January 1 will not be visible from Nambour.
Dateline - 12 December 2009: Geminid meteor swarm approaching
This weekend, Earth will pass through a stream of debris from extinct comet 3200 Phaethon, source of the annual Geminid meteor shower. Forecasters expect more than 100 meteors per hour to fly out of the constellation Gemini when the shower peaks on December 13 and 14.

Dateline - 18 November 2009: Fireball over the USA
As forecasters predicted, the Leonid meteor shower peaked during the early hours of November 18, favouring sky watchers in Asia with an outburst of 100+ meteors per hour. Just as the outburst was dying down, an even bigger event took place over the western USA. Something hit Earth's atmosphere and exploded with an energy equivalent of 0.5 to 1 kiloton of TNT. Witnesses in Colorado, Utah, Idaho and elsewhere say the fireball "turned night into day" and "shook the ground" when it exploded just after midnight Mountain Standard Time. Researchers who are analyzing infrasound recordings of the blast say the fireball was not a Leonid. It was probably a small asteroid, now scattered in fragments across the countryside. Efforts are underway to measure the trajectory of the asteroid and guide meteorite recovery efforts. Full story
Dateline - 16 November 2009: Leonid meteor shower due mid-week
The Leonid meteor shower peaks on Wednesday morning, November 18, with a new Moon providing ideally-dark viewing conditions. Forecasters expect a relatively mild display (20 to 30 meteors per hour) over North America followed by a much stronger outburst (100 to 300 per hour) over Australia and Asia. No matter where you live in Australia, the best time to look is from 2 am to 4 am on Wednesday morning. Full story
Dateline - 13 November 2009: The Moon is not waterless after all
The argument that the Moon is a dry, desolate place no longer holds water. At a press conference today, researchers revealed data from NASA's LCROSS mission indicating that water exists in a permanently shadowed crater near the lunar South Pole. See articles below, datelined 8 October 2009 and 17 October 2009. Full story
Dateline - 10 November 2009: A possible outburst of the Leonid meteor shower arrives next Wednesday morning
The 2009 Leonid meteor shower peaks at 3:30 am on November 18. Although predictions vary between 3 and 30 meteors per hour, an outburst of many more than that is a possibility. NASA says that between 200 and 300 per hour may be seen over Australia and East Asia. There will be no moonlight to interfere with observations, so this could be one of the best meteor showers in years. Full story

Dateline - 28 October 2009: Small asteroid explodes over Indonesia
A 10 metre asteroid exploded over Indonesia with the force of three Hiroshima bombs - and no one on Earth knew it was coming. The New Scientist website reports the dramatic explosion over South Sulawesi, Indonesia, on October 8, and underscores how blind humanity is to the danger of giant space rocks. NASA estimated the explosion was the equivalent to 50 000 tons of TNT, making it one of the largest asteroid explosions ever observed. However, this time we were lucky - the blast caused no damage on the ground because it occurred at high altitude, 15 to 20 km above Earth's surface. While the explosion was heard by witnesses in Indonesia and picked up by international nuclear explosion detectors, the asteroid only became visible after it exploded. News storyf More
Dateline - 23 October 2009: NASA mission to study the Moon's tenuous atmosphere - before it's too late
The Surveyor 7 spacecraft that landed on the Moon in January 1968 took photographs showing that the Moon had a very thin 'atmosphere' (more properly termed an 'exosphere') of electrostatically charged particles that became active and rose above the surface in sunlight and fell to the ground in the lunar night. Apollo astronauts confirmed this phenomenon. Now NASA scientists are building a probe to be called LADEE (Lunar Atmosphere and Dust Environment Explorer) to investigate this process, and which chemicals are most active. Full story
Dateline - 19 October 2009: Orionid meteor shower peaks tomorrow and Thursday
Caused by debris from Halley's Comet, the 2009 Orionid meteor shower peaks on Wednesday, October 21 and Thursday, October 22, and forecasters say it could be an unusually good show. "Earth is passing through a stream of debris from Halley's Comet, the source of the Orionids," says Bill Cooke of NASA's Meteoroid Environment Office. "Flakes of comet dust hitting the atmosphere should give us dozens of meteors per hour." Full story

Dateline - 22 September 2009: New large sunspots appear
In a year when the sun has been utterly blank 80% of the time, the sudden emergence of two large sunspots in a single day is a noteworthy event. Today is such a day. NASA satellites and amateur astronomers are monitoring a pair of growing sunspots, both apparently members of long-overdue Solar Cycle 24. The emergence of these active regions is not enough to end the deepest solar minimum in nearly a hundred years, but they do represent a significant uptick in solar activity. More

Dateline - 11 September 2009: LCROSS satellite will impact the Moon in four weeks time
In search of water, NASA's Lunar Crater Observation and Sensing Satellite (LCROSS) is on a collision course with the Moon. The impact will occur on the evening of 9 October next, at 10:30 pm AEST. The site chosen for the impact is the small crater Cabeus A, near the lunar south pole. LCROSS will search for ice by plunging its spent upper-stage Centaur rocket into the permanent shadows of Cabeus A, where water might be trapped in frozen form. The LCROSS satellite will then fly into the plume of debris kicked up by the impact and measure the properties of the plume before it also collides with the lunar surface. Observing from Nambour, the waning gibbous Moon at the time of impact will be below the north-eastern horizon, not rising until 11 pm. Full story
