Me and my big ideas
Viskas bus labai gerai. Turėsiu laiko ir erdvės viską gerai apgalvoti. Kas norės - tas mane ras, o visiems kitiems - gerų metų ir gero gyvenimo.
Welcome Home Apollo 8
Although it was past 2 a.m. on Dec. 29, 1968, more than 2,000 people
were on hand at Ellington Air Force Base to welcome the members of the
Apollo 8 crew back home. Astronauts Frank Borman, James Lovell and
William Anders had just flown to Houston from the Pacific recovery area
near Hawaii. The three crewmen of the historic Apollo 8 lunar orbit
mission are standing at the microphones in center of picture.

Fastest Rotating Star Found in Neighboring Galaxy
This artist's concept pictures the fastest rotating star found to date.
The massive, bright young star, called VFTS 102, rotates at a million
miles per hour, or 100 times faster than our sun does. Centrifugal
forces from this dizzying spin rate have flattened the star into an
oblate shape and spun off a disk of hot plasma, seen edge on in this
view from a hypothetical planet. The star may have "spun up" by
accreting material from a binary companion star. The rapidly evolving
companion later exploded as a supernova. The whirling star lies 160,000
light-years away in the Large Magellanic Cloud, a satellite galaxy of
the Milky Way.

New Year resolution
That would be to allow myself to be happy. To let things flow in it's natural way. To live life as it goes. Looks like I have met someone I could think of spending the rest off my life together. It doesn't mean he has to feel the same way. That lesson I have already learnt. He makes me feel warm and alive and that's the greatest thing ever. Butterflies only mess up with your head and this new feeling is much better. Then again, that's how I feel, so I pray for higher forces to let me read the signs right and not be hurt once more.
Lygiai prieš du metus šią naktį praradau savo mažąjį begemotuką, tačiau tikriausiai įgijau mažą angeliuką, kuriam kol kas nelabai sekėsi mane saugoti. Tikriausiai todėl, kad dar mažas ir nepatyręs. Kada nors ir jis taps dideliu stipriu angelu ir gerai saugos savo mamytę.

Orange and Blue Hazes
This view from NASA's Cassini spacecraft looks toward the south polar
region of Saturn's largest moon, Titan, and shows a depression within
the moon's orange and blue haze layers near the south pole.
The moon's high altitude haze layer appears blue here; whereas, the main atmospheric haze is orange. The difference in color could be due to particle size of the haze. The blue haze likely consists of smaller particles than the orange haze.
The depressed or attenuated layer appears in the transition area between the orange and blue hazes about a third of the way in from the left edge of the narrow-angle image. The moon's south pole is in the upper right of this image. This view suggests Titan's north polar vortex, or hood, is beginning to flip from north to south.
The southern pole of Titan is going into darkness as the sun advances towards the north with each passing day. The upper layer of Titan's hazes is still illuminated by sunlight.
Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were obtained on Sept. 11, 2011 at a distance of approximately 83,000 miles (134,000 kilometers) from Titan. Image scale is 2,581 feet (787 meters) per pixel.

Ring of Fire
This composite image shows the central region of the spiral galaxy NGC
4151. X-rays (blue) from the Chandra X-ray Observatory are combined with
optical data (yellow) showing positively charged hydrogen (H II) from
observations with the 1-meter Jacobus Kapteyn Telescope on La Palma. The
red ring shows neutral hydrogen detected by radio observations with the
NSF's Very Large Array. This neutral hydrogen is part of a structure
near the center of NGC 4151 that has been distorted by gravitational
interactions with the rest of the galaxy, and includes material falling
towards the center of the galaxy. The yellow blobs around the red
ellipse are regions where star formation has recently occurred.
A recent study shows the X-ray emission probably was caused by an outburst powered by the supermassive black hole located in the white region in the center of the galaxy. Evidence for this idea comes from the elongation of the X-rays running from the top left to the bottom right and details of the X-ray spectrum. There are also signs of interactions between a central source and the surrounding gas, particularly the yellow arc of H II emission located above and to the left of the black hole.
NGC 4151 is located about 43 million light years away from the Earth and is one of the nearest galaxies that contains an actively growing black hole. Because of this proximity, it offers one of the best chances of studying the interaction between an active supermassive black hole and the surrounding gas of its host galaxy. Such interaction, or feedback, is recognized to play a key role in the growth of supermassive black holes and their host galaxies. If the X-ray emission in NGC 4151 originates from hot gas heated by the outflow from the central black hole, it would be strong evidence for feedback from active black holes to the surrounding gas on galaxy scales. This would resemble the larger scale feedback, observed on galaxy cluster scales, from active black holes interacting with the surrounding gas, as seen in objects like the Perseus Cluster.
These results were published in the Aug. 20, 2010 issue of The Astrophysical Journal Letters. The authors were Junfeng Wang and Giuseppina Fabbiano from the Harvard Smithsonian Center for Astrophysics (CfA); Guido Risaliti from CfA and INAF-Arcetri Observatory, in Firenze, Italy; Martin Elvis from CfA; Carole Mundell from Liverpool John Moores University in Birkenhead, UK; Gaelle Dumas and Eva Schinnerer from the Max Planck Institute for Astrophysics in Heidelberg, Germany; and, Andreas Zezas from CfA and the University of Crete in Greece.

Me and my big ideas
So now I wake up. Iš tikrųjų viskas baigėsi labai seniai, vasarą. Tik tada dar to nežinojau. Kažko vis laukiau. Paskui prasidėjo lomkės, tačiau tai jau buvo tik mano asmeninės lomkės. Todėl metų pabaiga nieko ir nereiškia. Mes jau seniausiai baigėmės.
Stebuklų nebūna, tėra tik atsitiktinumai - laimingi arba ne. Ne kiekviena žemėn nukritusi sėkla duoda derlių. Nėra tokio dalyko kaip turi būti, todėl sakau, kad taip tiesiog atsitiko.
Tarsi seniai mirusi žvaigždė, kažkur visatos pakrašty, kurios šviesą vis dar matome, tačiau kūno jau nebėra. Praskriejanti kometa, ryškiai šviečiantis laikinas svečias žiemos danguje.
Ratas apsisuko, aš vėl visa ko pradžioje.

All our days
I'm full of all the good emotions and have nobody to share it with. And that's not right. Strange. Can't wait for this year to be over. Never had such a bad year. Overall, I know it won't get any better. I'm too smart to believe in miracles. And too old. But then again, every time this year I look into the future and hope that next year will be different. How stupid of me.
Kiekvieną kartą šiuo laiku galvoju, kad jau kitais metais tai viskas bus kitaip. O gaunasi kaip visada. Jei būtų pasaulinis lipimo ant to pačio grėblio čempionatas, aš tikrai būčiau nepralenkiama nugalėtoja. Noriu, kad viskas baigtūsi, tačiau nenoriu, kad taip. Miegoti negalima pabusti. Kablelis vis nenori pasidėti teisingai. Kas būtu teisinga? Mylėti negalima pamiršti. Ir vėl nežinau. O ne, žinau, tik nenoriu. Nes dar nepramušiau galva sienos, o nepadaryti visko iki galo - negerai. Galėčiau pati iš savęs pasijuokti, tik kad niekas negirdėtų. Tiesą sakant, bijočiau būti su tokiu žmogumi kaip aš. Visko per daug. Jausmų, vilčių, pykčio, tikėjimo.
Too much expectations, too little reason. I'm not safe to be with. Once there were a boy and the man I loved. And they both got so scared of all that unconditional feeling, they just had to run away to keep their sanity in tact. I was left with an enormous split in my heart. This is how I've learnt I'm a natural disaster. Too dangerous to keep, too feeble to let go. I'm too obsessed with thing called free will. Looks like some people just don't won't to make up their own mind. In the end nothing has changed, I champion something others don't see the reason too.
Labas mama. Tu buvai teisi dėl visko. Tačiau geriau jau nebūtum buvus. Tikriausiai ir pati su manimi sutiktum.

Festival of Lights
WISE, NASA's Wide-field Infrared Survey Explorer, has a new view of
Barnard 3, or IRAS Ring G159.6-18.5, that is awash in bright green and
red dust clouds. Interstellar clouds like these are stellar nurseries,
where baby stars are being born.
The green ring is made of tiny particles of warm dust whose composition is very similar to smog found here on Earth. The red cloud in the center is most likely made of dust that is more metallic and cooler than the surrounding regions. HD 278942, the bright star in the middle of the red cloud, is so luminous that it is the likely cause of the surrounding ring's glow. The bright greenish-yellow region left of center is similar to the ring, though more dense. The bluish-white stars scattered throughout are stars located both in front of, and behind, the nebula.
Regions similar to this nebula are found near the band of the Milky Way galaxy in the night sky. This nebulas is slightly off this band, near the boundary between the constellations of Perseus and Taurus, but at a relatively close distance of only about 1,000 light-years, the cloud is a still part of our Milky Way.
The colors used in this image represent specific wavelengths of infrared light. Blue and cyan (blue-green) represent light emitted at wavelengths of 3.4 and 4.6 microns, which is predominantly from stars. Green and red represent light from 12 and 22 microns, respectively, which is mostly emitted by dust.
