《每日邮报》10月23日推出天文爱好者拍摄的一组太阳大图

The sun may be 93 million miles away from Earth, but that hasn't stopped amateur astronomer Ralph Smith capturing these stunning close-ups from his garden.
Mr Smith, from Deeral in Queensland, Australia, used off the shelf equipment to capture the detailed snaps.
The stunning results show huge bursts of flames - known as prominences - leaping from the sun's surface.

Ralph Smith seen with his telescope who captured the close ups of the sun in Queensland, Australia. 'All of my equipment is off the shelf amateur astronomy gear. It is all within reach of a normal working person,' he said.

Others highlight giant sunspots (in the centre of this image) which are often larger in size than Earth itself. Sunspots form from shifting magnetic fields at the sun's surface, and are actually cooler than their surrounding solar material

The red-glowing looped material is plasma, a hot gas comprised of electrically charged hydrogen and helium

红色部分是太阳表面喷射的龙卷风状等离子流

Mr Smith said: 'The sun is of course a star and it is forever changing. It does so by the minute, which makes it a fascinating subject to photograph'
Ralph Smith 先生说，太阳总是处于不断变幻之中，创造出了令人眼花缭乱的美景

The prominence plasma (pictured) flows along a tangled and twisted structure of magnetic fields generated by the sun's internal dynamo
太阳风（太阳等离子体)。太阳风暴是太阳因能量增加向空间释放出的大量带电粒子形成的高速粒子流。所以太阳风暴中的气团主要内容是带电等离子体，并以每小时150万到300万千米的速度闯入太空。

According to Nasa, the sun is currently in the midst of an active phase of its 11-year solar weather cycle and is expected to reach peak activity sometime this year.
按照NASA的观点，太阳正值壮年，每隔11年会有一次太阳周期。太阳活动周期（solar cycle），或称为太阳磁活动周期（solar magnetic activity cycle），是太阳黑子数及其他现象的准周期变化，大约11年为一个周期。它会引起空气中、地面上一些物质的变化，甚至可能改变气候。通过计算可见的太阳黑子出现的频率和位置，这个周期可以被观测出。

Mr Smith, who has only been photographing the sun, and features such as these solar prominences, for around 14-months, said: 'There are no text books on this subject and I have developed my own methods over time to get a good result'

Ralph Smith先生是唯一连续观测太阳风暴长达14个月的爱好者，并形成了自己的一套观测办法

哈哈，第二幅图，那个赤道仪除了颜色几乎和星特朗的CG5一样，不过貌似名字好像不是CG5，有点像信达早期的赤道仪，不过几乎是一路货色，这个老外也挺抠门{:soso_e151:}

这个不算抠门，而是充分利用设备价值，物尽其用。

好大的院子，羡慕。

蔚为壮观！
牧场的环境也令人羡慕。
