You may guest - it is a jellyfish in a fish tank or somewhere in the ocean. Actually, it is a "jellyfish" from the space! Please, read the following information adapted from NASA for the explanation:

Jumbo Jellyfish or Massive Star?

Some might see a blood-red jellyfish in a forest of seaweed, while others might see a big, red eye or a pair of lips. In fact, the red-colored object in this new infrared image from NASA's Wide-field Infrared Survey Explorer (WISE) is a sphere of stellar innards, blown out from a humongous star.

The star (white dot in center of red ring) is one of the most massive stellar residents of our Milky Way galaxy. Objects like this are called Wolf-Rayet stars, after the astronomers who found the first few, and they make our sun look puny by comparison. Called V385 Carinae, this star is 35 times as massive as our sun, with a diameter nearly 18 times as large. It's hotter, too, and shines with more than one million times the amount of light.

Fiery candles like this burn out quickly, leading short lives of only a few million years. As they age, they blow out more and more of the heavier atoms cooking inside them -- atoms such as oxygen that are needed for life as we know it.

The material is puffed out into clouds like the one that glows brightly in this WISE image. In this case, the hollow sphere showed up prominently only at the longest of four infrared wavelengths detected by WISE. Astronomers speculate this infrared light comes from oxygen atoms, which have been stripped of some of their electrons by ultraviolet radiation from the star. When the electrons join up again with the oxygen atoms, light is produced that WISE can detect with its 22-micron infrared light detector. The process is similar to what happens in fluorescent light bulbs.

Infrared light detected by WISE at 12 microns is colored green, while 3.4- and 4.6-micron light is blue. The green, kelp-looking material is warm dust, and the blue dots are stars in our Milky Way galaxy.

This image mosaic is made up of about 300 overlapping frames, taken as WISE continues its survey of the entire sky -- an expansive search, sure to turn up more fascinating creatures swimming in our cosmic ocean.

V385 Carinae is located in the Carina constellation, about 16,000 light-years from Earth.

Solar Flare - 太陽表面的風暴或噴發熾熱氣體的現象。

美國科學家警告，地球有可能在2012年9月遭遇「超級太陽風暴」襲擊，並造成大面積停電，北美、歐洲、中國等地無一倖免。屆時，手機網絡可能癱瘓、互聯網崩潰、沒有任何信號的電視機如同廢物，而收音機將只能聽到一連串的靜電噪音。英國    《新科學家》雜誌去年一篇報道指出，屆時太陽表面噴發出的高能量粒子會影響地球磁場，90秒鐘內能損毁300座變壓站，單是美國便有130萬人沒有電力供應。http://hk.news.yahoo.com/article/100512/4/hyn3.html

What is a Solar Flare? A flare is defined as a sudden, rapid, and intense variation in brightness. A solar flare occurs when magnetic energy that has built up in the solar atmosphere is suddenly released. Radiation is emitted across virtually the entire electromagnetic spectrum, from radio waves at the long wavelength end, through optical emission to x-rays and gamma rays at the short wavelength end. The amount of energy released is the equivalent of millions of 100-megaton hydrogen bombs exploding at the same time! The first solar flare recorded in astronomical literature was on September 1, 1859.

Two scientists, Richard C. Carrington and Richard Hodgson, were independently observing sunspots at the time, when they viewed a large flare in white light. As the magnetic energy is being released, particles, including electrons, protons, and heavy nuclei, are heated and accelerated in the solar atmosphere. The energy released during a flare is typically on the order of 1027 ergs per second. Large flares can emit up to 1032 ergs of energy. This energy is ten million times greater than the energy released from a volcanic explosion. On the other hand, it is less than one-tenth of the total energy emitted by the Sun every second. There are typically three stages to a solar flare. First is the precursor stage, where the release of magnetic energy is triggered. Soft x-ray emission is detected in this stage. In the second or impulsive stage, protons and electrons are accelerated to energies exceeding 1 MeV. During the impulsive stage, radio waves, hard x-rays, and gamma rays are emitted. The gradual build up and decay of soft x-rays can be detected in the third, decay stage. The duration of these stages can be as short as a few seconds or as long as an hour.

Solar flares extend out to the layer of the Sun called the corona. The corona is the outermost atmosphere of the Sun, consisting of highly rarefied gas. This gas normally has a temperature of a few million degrees Kelvin. Inside a flare, the temperature typically reaches 10 or 20 million degrees Kelvin, and can be as high as 100 million degrees Kelvin. The corona is visible in soft x-rays, as in the above image. Notice that the corona is not uniformly bright, but is concentrated around the solar equator in loop-shaped features. These bright loops are located within and connect areas of strong magnetic field called active regions. Sunspots are located within these active regions. Solar flares occur in active regions.

The Earth may be hit with unprecedented levels of magnetic energy from solar flares after the Sun wakes “from a deep slumber” sometime around 2013. Every 22 years the Sun’s magnetic energy cycle peaks while the number of sun spots – or flares – hits a maximum level every 11 years.

On Aug. 22, 2005, a pair of coronal mass ejections (CMEs) blasted off the Sun and headed toward Earth. The active region, known as AR 798, is located in the lower right corner of the image. The CMEs were associated with relatively small solar flares. NOAA reports that another flare is possible in Region 798.

The super storm would hit like “a bolt of lightning” and could cause catastrophic consequences for the world’s health, emergency services and national security unless precautions are taken. It may possibly damage everything from emergency services’ systems, hospital equipment, banking systems and air traffic control devices, through to “everyday” items such as home computers, iPods and Sat Navs.

美國科學家克萊格‧文特爾20日宣布成功制造出人造細胞“辛西婭”之後，引起全世界的震動。現在, 在科學界又一新發現: 根據美國太空總署的土星探測船卡西尼號(Cassini)傳返地球的信息，科學家發現，土星最大的衛星土衛六，即是泰坦(Titan)，存在原始生命體。 泰坦有大氣層，且地表有山脈、湖泊與河流，被視為太陽系中與地球最相似的星體。

科學家分析泰坦表面的流體並不是水，而是甲烷，亦即是生命體的基礎；另外，科學家亦發現，氫氣經泰坦的大氣層向下流動，最後在地表上消失，這顯示可能有蟲 類在呼吸，而泰坦表面亦缺乏某些特定的化學物(如乙炔)，代表可能是被生命體消耗掉了。綜合以上兩點，科學家推測，泰坦上的確存有外星生命，但這種生命可 能是一種不靠水維生的生命形式。

科學家結合前述兩個現象，認為是以甲烷為基礎的生命體存在的兩個必要條件，而當太陽提供的熱能與溫暖足夠時，泰坦生命體出現的過程會被啟 動。科學家還大膽預言，當40億年之後，太陽膨脹成紅巨星吞掉地球，並且提供泰坦足夠的熱能時，宇宙裡生命的天堂就將不再是地球，而是泰坦衛星了。

但這只是觀察, 泰坦有生命與否, 還未有實質証據, 結論尚早!  不過, 只少比山上"挪亞方舟"的"証據", "泰坦生命"則實在得多!

The temperatures on Titan are around -170ºC; water is frozen on Titan's surface. Other liquid medium is needed for living processes; one candidate is liquid methane. Recently, the data returned by NASA's Cassini spacecraft suggested that hydrogen was flowing down through Titan's atmosphere and disappearing at the surface!

後加:

氫氣是很輕, 理應向上升, 正如氫氣球, 但泰坦的氫氣是向下流動,
"非生命因素"很難解析此情況, 反看地球上的氧氣是有遁還的 (Oxygen Cycle), 很可能泰坦地上或海洋裡有生物把大量氫氣吸敢, 以令致大量氫氣向下流動.
