China unveils ambitious space projects, to probe black holes, search for aliens...

BEIJING, Aug. 21 (Xinhua) -- China will launch several space projects, including a hard X-ray telescope for black hole studies, between 2014 and 2016, according to a senior Chinese astronomer.

Su Dingqiang, an academic at the Chinese Academy of Sciences and former president of the Chinese Astronomical Society, revealed some details regarding the hard x-ray modulation telescope (HXMT), China's first space telescope, on Tuesday at the opening ceremony of the International Astronomical Union (IAU)'s 28th General Assembly.

The hard X-ray band is a key waveband for high-energy astrophysics studies. Hard X-rays originate mostly from regions close to black holes and have high penetrative power, making them important tools for studying physical processes in extreme conditions, such as high matter density and high energy density.

Su said China will develop another satellite, the dark matter particle explorer (DAMPE), to help detect high-energy electrons and gamma rays, as well as a telescope to study the solar magnetic field and a Sino-French joint mission to study gamma ray bursts.

Su said Chinese scientists are also planning to establish an Antarctic astronomical observatory.

Cui Xiangqun, an academic at the Chinese Academy of Sciences and president of the Chinese Astronomical Society, said a lot of work has been done to gain experience for the future construction of an observatory in the Antarctic.

An Antarctic Survey Telescope (AST) was installed there at the beginning of the year and another AST will be installed in 2013, said Cui. China's first Antarctic telescope was installed in 2009.

"We can only send scientists there once a year and each time they can stay no more than three weeks. These telescopes help us detect problems via remote control," Cui said.

"Some of the technological problems we face there are similar to those in space, like low temperatures," Cui said.

However, Cui was optimistic about the Antarctic facility. "It has drier air, better visibility and fewer background disturbances. Its turbulent boundary layer is closer to the ground compared to other sites on the ice slope," she said while describing the area near the telescope.

Chinese space exploration has developed rapidly in the past decade. Some large-scale astronomical projects in China, including the Large Sky Multi-Object Fiber Spectroscopic Telescope (LAMOST) completed in 2008 and the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) to be completed in 2016, have drawn global attention.

The ongoing conference, the first of its size to be held in China, is itself a historic occasion for the country.

"China's technology has advanced markedly, and some of its buildings are really world-class. The fact that we are meeting here is an indication that China has emerged in a short period of time to be competitive on the world stage in the science of astronomy," said Robert Williams, IAU president.

China to probe black holes, search for aliens

Look out space, the Chinese are coming...

China will ramp up its space exploration plans from 2014, with shiny new kit to probe black holes, study dark matter and search for signs of alien life, according to one of the country’s top astro-boffins.

Su Dingqiang, former president of the Chinese Astronomical Society and member of the Chinese Academy of Sciences, revealed the plans to local media at the opening ceremony of the International Astronomical Union (IAU)'s 28th General Assembly on Tuesday.

He said that a hard x-ray modulation telescope (HXMT), currently under construction, will be sent into orbit around the Earth between 2014 and 2016 using a Ziyuan II satellite, according to Xinhua.
The HXMT project web site has the following on the telescope:

Hard X-ray band is a key waveband for high energy astrophysics study. Exploring various kinds of black holes is a major frontier of physics and astronomy in the new century. Hard X-rays originate mostly from regions closest to black holes and are highly penetrative, and are therefore important tools for studying the physical processes in the extreme conditions such as high matter density, high energy density, high electric-magnetic field, and high gravitational field.

Also planned is a dark matter particle explorer (DAMPE), expected to be launched by 2015, as well as a telescope to study the solar magnetic field and a joint project with France to study gamma ray bursts, the report said.

Always striving to be the biggest and best on Earth, China is also set to complete the world’s largest radio telescope in 2016.

The 500-metre aperture single dish giant is being built in in Guizhou province, southern China, at a cost of over 700 million yuan (£69.3m).

It’s designed to be three times more sensitive than the current world record holder, meaning that it should be able to see further into space than ever before.

For the record, it will supplant the Arecibo Observatory in Puerto Rico – known to Bond fans as the setting for the climax of Brosnan flick Goldeneye – as the world’s largest and most sensitive single aperture telescope. ®

Why Malaysian Evidence Act Section 114A should be repealed

Continued opposition to this piece of legislation may yet result in it being taken off the statute books.

THE recent amendment to the Evidence Act with the insertion of Section 114(A) basically presumes that a person who is depicted in a publication as owner or administrator is presumed to have published the contents.

This effectively means that those named in publications are presumed guilty of any offending content that may be posted, including those on the Internet where there is no licensing and it is easy to use some other person’s name, photograph and details as the originator.

This presumption of guilt, requiring the accused to prove his innocence, instead of the prosecution having to prove his guilt, is a strange reversal of the rule of law when the entire justice system is based on the assumption of innocence unless guilt is proven.

It is stranger still coming in the wake of moves to liberalise draconian laws such as the Internal Security Act which provided for detention without trial, and the Universities and University Colleges Act which severely curtailed the rights of students to participate in the political process.

When there is such liberalisation taking place, it is strange that the Government should be setting the clock back by introducing legislation that goes clearly against the grain of justice.

Yes, the Internet space is a raucous one and lots of stuff are pasted and posted, and people, including many in the Government, the Cabinet and the Opposition, are regularly blasted for things that they may or may not have done.

But there are laws to deal with them such as the defamation laws. And some of the victims have sought recourse to these with visible success, which includes Information, Communications and Culture Minister Datuk Seri Dr Rais Yatim.

Why, therefore, should a sledgehammer be given to prosecutors to bring a tonne of weight down indiscriminately on people who may not have committed the offence, but may have a tough time proving that they had not and may become involved in tangled knots with the law for a long time?

Conspiracy theorists, of whom a lot exist in this country due to the nature of the way things are, have immediately seen this as a move to limit criticism. That’s hardly a PR effort by the Government.

When the Centre for Independent Journalism organised an Internet blackout on Aug 14, it met with a tremendous response and many people just did not post anything on the Net during that particular day.

Such support must have had an effect on the decision of the Prime Minister to call upon the Cabinet to review its decision to pass the amendment to the relevant Act.

“Whatever we do we must put the people first,” the PM had tweeted, and who can disagree with that?

But unfortunately, the Cabinet stuck to its guns and backed its previous decision.

Dr Rais said the Cabinet discussed it exhaustively and decided not to make any changes because Parliament was represented by the ruling party and the Opposition and had debated it.

“Once it is officially passed, to do something now is an afterthought,” he said.

Dr Rais added that the Law Minister would explain further.

Later, Home Minister Datuk Seri Hishammuddin Hussein said the controversial amendment would be explained further by the Attorney-General.

“If explained properly, I believe right-thinking people will know why the amendment was tabled in Parliament and approved. If there still are fears, laws can also be tweaked, amended and abolished, but don’t get emotional about it,” he said.

Those interested will wait for the Government explanation, although Dr Rais had already said that presumption of fact was nothing new in law and there was still room for accused persons to defend themselves.

The converse position is that such a law can be abused.

Those who want to “fix” someone on the Net can post comments and claim that it came from that particular person. And that person will be tied up in knots trying to defend himself.

That is the main fear among Internet users and other publishers.

Inordinate power is in the hands of prosecutors who now don’t have to prove who the real publishers are.

The question is why grant them these additional powers under the amendment when the entire Internet is subject to the laws of the country?

The only difference is that there is no licensing of the Internet compared to conventional media such as print and broadcasting.

Thus, the new laws are seen as a move to bring the Internet under control more quickly than using existing laws, a move which the disinterested would oppose.

Policymakers may actually realise that. As seen by the quote from the Home Minister above, if there is continued strong opposition to the amendment, it could be repealed.

Perhaps it may need another tweet from the Prime Minister to make that happen, and this time he will be at that Cabinet meeting.

That should make a difference to what the Cabinet may think.
