Red beaches glow blue

Posted on by

Video will begin in 5 seconds.

The crashing waves of Bondi and Coogee caught onlookers by surprise as blue light shone from the water, a product of the recent algae infestation.

The algae that turned some of Sydney's beaches red this week is making the ocean glow blue at night.

The striking blue light was spotted at Bondi and Coogee beaches late on Wednesday night, as well as south of Sydney.

I've never seen anything like it in my life. It was like something from space.

Laurence Palmer was leaving dinner with his girlfriend at Bondi when he looked out to sea and noticed the glow.

"The most amazing blue light could be seen coming from the ocean. People were standing and staring at the incredible natural light show," he said. "When the waves crashed the sea was turning blue."

A marine microbiologist from University of Technology Sydney, Justin Seymour, said the algae glows when the water is agitated, leaving a trail of neon blue.

Australia beaches reopen after red algal bloom

Posted on by

Beaches around southeastern Australia's coastline reopened after a red algal bloom that glowed a phosphorescent blue at night forced them to close to the public.

The algae, noctiluca scintillans, forced swimmers and surfers out of the water at Sydney's Bondi and a number of neighbouring beaches earlier this week, and it spread along the fringes of two states.

One of the worst affected beaches, Clovelly in Sydney, reopened Friday, just in time for a predicted heatwave over the weekend.

"There is no sign of the red algal bloom that kept the beach closed from Tuesday to Thursday this week," the local council said, a sentiment echoed by other councils along the city's northern beaches.

"It is now safe to swim, at the moment," a Surf Life Saving NSW official told reporters.

"We'll continue to monitor the situation."

Aerial footage shot over parts of New South Wales and neighbouring Victoria state showed huge blooms of the oily red to pink scum this week, which has a fishy odour and can irritate the skin and eyes but is not dangerous to humans.

One of the most striking features was the way it glowed blue at night, earning it the nickname "sea sparkle".

The Sydney South Coast and Hunter Regional Algal Coordinating Committees said the blooms typically occur as a result of currents bringing cold, nutrient-rich water to the surface.

Erlang in global radio astronomy - monitoring and controlling custom built hardware at the bit level
This is a video of Harro Verkouter #39;s talk at London erlang Factory Lite http://www.erlang-factory.com In radio astronomy - the field I work in - data processing requirements are so large we have to build custom hardware to actually do it. In the talk I would like to introduce the observation technique we currently use, very long baseline interferometry, and the hardware that is currently being developed for expanding its capabilities. Feeding and controlling this FPGA powered device will require a distributed system also capable of controlling embedded devices remotely over a network. A primary objective was to produce a system where the hardware developers and VHDL programmers (not generally Erlang savvy programmers) should also be able to use the code to easily interact with their logic code running on the FPGAs. Talk objectives: I would like to show that Erlang is really good at what it was written for: interacting with (embedded) systems, dealing with binary data, running a distributed system for monitoring and controlling it. Target audience: Technology oriented people with an interest in low level programming or global high-speed network connections being used in a real time radio astronomical application. Talk may contain traces of physics.From:ErlangSolutionsViews:0 0ratingsTime:28:18More inScience Technology

Doomsday Postponed: Mayan Calendar May Be Wrong – Video

Doomsday Postponed: Mayan Calendar May Be Wrong
Doomsday Postponed: Mayan Calendar May Be Wrong It looks like those preparing for the end of the world on December 21, 2012 may have some more time to get ready. According to a new report, the conversion from the Mayan calendar to the Gregorian calendar may have been conducted improperly, leading to a potential multi-decade miscalculation: A new critique, published as a chapter in the new textbook "Calendars and Years II: Astronomy and Time in the Ancient and Medieval World" (Oxbow Books, 2010), argues that the accepted conversions of dates from Mayan to the modern calendar may be off by as much as 50 or 100 years. That would throw the supposed and overhyped 2012 apocalypse off by decades and cast into doubt the dates of historical Mayan events. (The doomsday worries are based on the fact that the Mayan calendar ends in 2012, much as our year ends on Dec. 31.)

Another radio-telescope launched in WA

Posted on by

Preliminary data from the $51 million Murchison Widefield Array (MWA) radio telescope in Western Australia's outback is already on a par with the best results ever achieved, Special Minister of State Gary Gray says.

The low-frequency radio telescope at the Murchison Radio-astronomy Observatory, which is about 315km northeast of Geraldton, was officially launched on Friday.

It is one of three precursors to the Square Kilometre Array (SKA) project, which will be the largest and most capable radio telescope ever made.

The SKA will provide scientists with the farthest peek into the universe and therefore, time.

That $2 billion project will comprise 3000 dishes spanning South Africa, Australia and New Zealand, and will be funded by a consortium of 20 nations.

Mr Gray said the MWA was the only precursor to the SKA to focus on low-frequency radio waves that would enable scientists to understand for the first time how the universe had evolved since the big bang 13.7 billion years ago.

It will also help to identify the trajectory of solar storms, quadrupling the warning period currently provided by near-earth satellites.

The impressive early data already collected from the MWA used only a fraction of its capability, Mr Gray said.

"This is cutting edge technology - it will enable us to look back and look forward," he said.

"It is extraordinary that we are today looking at gathering information sent more than 13 billion years ago.

The $51 million Murchison Widefield Array radio-telescope in the remote outback of Western Australia has been launched, boosting the nation's rapidly advancing radio-astronomy capabilities.

The low-frequency radio-telescope at the Murchison Radio-astronomy Observatory, about 315km northeast of Geraldton, is a key precursor to the Square Kilometre Array project, which will be the largest and most capable radio-telescope ever made.

The SKA will provide scientists with the farthest peek into the universe and therefore, time.

That $2 billion project will comprise 3000 dishes spanning South Africa, Australia and New Zealand, funded by a consortium of 20 nations.

Special Minister of State Gary Gray said the MWA was one of three precursors to the SKA.

"It is the only one that will focus on the collection of low frequency radio waves which will enable scientists, for the first time, to understand how the universe has evolved since the big bang," Mr Gray said.

He said the MWA involved eight years' work between a consortium of 13 research institutes from Australia, India, New Zealand and the United States, led by WA's Curtin University.

WA Science and Innovation Minister John Day said the MWA would be the first of the three SKA precursor projects to be fully operational, with observations set to commence early next year.

The CSIRO's ground-breaking, 36-dish Australian Square Kilometre Array Pathfinder radio-telescope, also at the Murchison Radio-astronomy Observatory, was officially launched last month.

India’s first astronomy-photography festival from December 8

Posted on by

Three-week-long event to be held at Teen Murti House

A three-week-long India Astro Photo Festival (IAPF) featuring images of celestial events like the infrequent transit of Venus, and solar and lunar eclipses begins at Teen Murti House premises here from December 8.

Described as Indias first astronomy-photography festival, the first edition of IAPFs will showcase a wide array of detailed telescopic images of deep-sky objects like galaxies and nebulae, earth and sky photographs of heritage sites, observatories and different landscapes under the night sky.

Organised by the Nehru Planetarium in association with Amateur Astronomers Association, Delhi, a major highlight of the event will be photographs of different Indian monuments and heritage sites captured against the star-studded night sky or during different celestial events.

According to Planetarium director N. Rathnasree, the festival assumes significance as it showcases the richness of our heritage. Never have Indian monuments been photographed like this before by amateur astronomers. Budding astronomers have captured world heritage sites on their lens. Celestial activities have been captured against the background of medieval monuments like Humayuns Tomb, Jantar Mantar, Purana Quila and Qutub Minar, Khajuraho Temple, Sanchi Stupa and Chittorgarh Fort.

The astro-photographers, predominantly amateur astronomers from the United States, the United Kingdom, Greece, France, Croatia, China, Pakistan, Romania, Denmark, Norway and Italy, will exhibit their photographs in the exhibition. A two-day astrophotography workshop will be conducted at Planetarium here from December 8. The festival basically wants to create awareness about one of the least-explored branch of photography among amateur astronomy and photography enthusiasts through workshops and discussions.

Combining Planetary Science And Astronomy To Hunt For Exoplanets

Lawrence LeBlond for redOrbit.com Your Universe Online

Have you ever looked up at the night sky and wondered just how many of the stars you see might have planets orbiting them, and if so, what those planets might be like? Our galaxy alone contains at least 200 billion stars, and researchers have been searching effortlessly to find out just how many of these Milky Way stars have orbiting planets.

The first exoplanets, planets orbiting distant stars in our Galaxy and beyond, were discovered in the early 1990s. Since then, the count on planet-bearing stars has climbed to more than 850, thanks in part to the development of better planet-hunting telescopes such as the Kepler Space Telescope. Since its launch in 2009, the Kepler mission has discovered no less than 2,300 exoplanet candidates.

With information like this in hand, astronomers are now estimating that the Milky Way has an average of at least one planet per star, raising the probability that there are at least 200 billion exoplanets in our Galaxy alone.

This sudden emergence of thinking has brought two generally-isolated fields together: planetary science, which generally focuses on the inside of our solar system, and astronomy, which typically looks beyond it. Planetary scientists are learning to use what astronomers know about solar systems beyond ours to help formulate the origins of our solar system, while astronomers are taking a keen interest in learning what their peers know about planet formation on a galactic scale.

With this knowledge in hand, a collective of nine astronomers and planetary scientists from Caltech are forming a new Center for Planetary Astronomy, essentially combining two fields into one. This new scientific presence will help maintain collaborations between the two fields, it will help attract new funding and fellowships for young scholars, and recruit top students and postdoctoral scholars.

The collective includes the likes of planetary science professor Geoff Blake, astronomy professor Lynn Hillenbrand, and senior research associate John Carpenter, all who study planet-forming disks of gas and dust around young stars. The group also includes infamous Pluto-killer Mike Brown, the Richard and Barbara Rosenberg Professor and professor of planetary astronomy. Brown studies fossil-like rubble from such planet-forming disks.

The remaining scientists focus primarily on the planets themselves. John Johnson, an assistant professor of planetary astronomy, is concerned with detection and characterization of exoplanets, those comparable to Earth, and also studies how stars masses affect planet formation. Heather Knutson, assistant professor of planetary science, studies composition, temperatures, atmospheres and weather of exoplanetary bodies. Yuk Yung, the Smits Family Professor of Planetary Science, studies the atmospheres of planets. Dave Stevenson, the Marvin L. Goldberger Professor of Planetary Science, studies how planetary interiors evolve. And finally, Greg Hallinan, an assistant professor of astronomy, studies radio signals emitted from exoplanets, which may indicate the presence of magnetic fields, which could mean these exoplanets are habitable or even already contain life.
