The vastness of space and the puzzling nature of the cosmic objects that occupy it provides no shortage of material for astronomers to ponder.
To round up some of the most enduring mysteries in the field of astronomy, the journal Science enlisted help from science writers and members of the Board of Reviewing Editors to choose eight puzzling questions being asked by leading astronomers today.
As Robert Coontz, deputy news editor at Science, writes in his introduction to the series, the participants decided that, "true mysteries must have staying power," rather than being questions that might be resolved by research in the near future. In fact, while some of the topics discussed may one day be solved through astronomical observations, others may never be solved, he added.
In no particular order, here are eight of the most compelling mysteries of astronomy, as presented by the journal Science:
The airline industry will meet this weekend for its annual summit. It will discuss the effects of oil price reduction against the latest fears over the global economy. It is likely to leave its overall industry profit forecast broadly unchanged at the June 10-12 meeting.
New York, June 9 (SharewellNeswire.com) - The chiefs of the airline industry will be meeting in China this weekend for their annual summit and among the issues that they will discuss will be the latest fears over the global economy and the impact of cheaper oil prices on their financial forecasts.
The industry has been badly impacted by record fuel costs and the effect of the eight percent drop in oil prices this year will be showcased against the backdrop of Europe’s debt crisis and a slowdown in China’s economy. The director general of IATA said that the advantage of the reduction in fuel prices to the airline industry is being offset by concerns over world economic activity. He said that the industry will suffer more if the world faces an economic slump than because of higher fuel price.
It is expected that IATA, which has 240 members who collectively account for 84 percent of world air traffic, will leave its overall industry profit forecast broadly unchanged at the June 10-12 meeting. However, the forecast will likely show a wide divergence in different regions of the world due to the unabated European debt crisis and shifting of trade to the Middle East.
In 2011, global airline industry profits reduced by 50 percent and they are expected to go down a further 50 percent this year.
