SN2010jl supernova, Supernova At least I've found

SN2010jl supernova, Supernova At least I've found | New

  Observations made with NASA's Chandra X-ray Observatory, provides new evidence that the shock wave generated by the supernova is able to penetrate a collection of gas around a star that exploded. This discovery may help astronomers know the why some explosions

supernova supernova stronger than others.

On 3 November 2010, a supernova was found in galaxy UGC 5189A, located 160 million light-years from Earth with TODD data from the All Sky Automated Survey Telescope in Hawaii.

Composite image of UGC 5189A shows X-ray data in purple and optical data from Hubble telekop in red, green, and blue. SN 2010jl is the top of the galactic X-ray light is very bright.

Quoted from spacedaily.com, Tuesday (22/05/2012), The research team used NASA's Chandra X-ray Observatory to observe this supernova in December 2010 and October 2011. This supernova is one of the brightest supernova of other supernova ever detected by X-rays.

With optical light, SN 2010jl 10 times brighter than other types of supernova that resulted from the explosion of massive stars. And it goes into the brightest supernova group that is currently known by the optical survey. Different explanations proposed to explain the supernova energy including supernova blast wave interaction with matter density around the star will explode. Radioactive resulting from instability of the supernova (dipisu by the conversion of gamma rays into particle and anti-anti-particle), and the emission from the core of the star with a strong magnetic field which is not unusual.

Data retrieved from NASA's Chandra X-ray Observatory shows that the X-rays from the supernova blast wave is absorbed by the surrounding gas collection. And collection of the gas comes from the star is still before he explodes.

It Able Star Forming Galaxies Hundreds of Times Faster than the Milky Way | New

Astronomers recently managed to find a galaxy that turns into gas that is around the stars. This unique galaxy burn the gas to reach the level of 100 percent combustion efficiency. Astronomers found the galaxies after making observations through the IRAMPlateau de Bure interferometer in the French Alps, NASA's Wide-field Infrared Survey Explorer (WISE) telescope Hubble and NASA."The galaxy gas burning engines similar to gas-powered cars and galaxies that have a" machine "highly efficient gas" said Jim Geach from McGill University as the lead author of the study in the journal of astrophysics. "This galaxy is like a sports car, the difference between a galaxy's gas change at the level of change in the most efficient," he added.Galaxy named SDSS J1506 +54 was discovered when astronomers looking at the survey data generated by the WISE infrared and infrared galaxies have so obviously that is equivalent to a thousand billion times our sun. "Because WISE was able to observe the entire sky, the galaxy is seen very clearly from other objects," said Ned Wright of UCLA as the principal investigator of WISE."These galaxies formed their stars hundreds of times faster than our Milky Way galaxy and it is the most extreme star formation," said Jim Geach. Astronomers using the IRAM Plateau de ure instrument interferometer to measure the amount of gas available in the galaxy. The result is detected the light waves of carbon monoxide as an indicator of the presence of hydrogen gas is the fuel of stars.Of these data with the data then astronomers menggabungkannnya WISE and Iram (to measure the mass of gas) and the astronomers were able to get a measure of the efficiency of star formation. The results show that afisiensinya reached the maximum theoretical known as the Eddington limit. Appropriate areas of new star formation, then the nearby gas clouds collapse due to gravity.When the gas condenses and have the power to push the atoms to trigger nuclear fusion reactions, the new stars will be born and at the same time the wind and radiation of new stars that can prevent the formation of new stars other by pressing the gas around it to prevent collapse clouds and larger gas.Eddington limit is the limit of the point where the force of gravity pulls gas simultaneously balanced with the amount of pressure coming out of the star. If it exceeds the Eddington limit wan gas will explode and the star formation process will be stalled. "We see the gas flowing out of the galaxy is millions of miles per hour and gas is likely driven by the strong radiation of the stars that were there," said Ryan Hickox, astrophysicist Dortmouth College, Hanover.It causes a galaxy SDSS J1506 +54 is remarkable is its ability to produce very fast star and galaxy evolution period is also very short Yag possibility tersbuet galaxy is a merger of the two different galaxies. An estimated ten million years longer tersbeut galaxy will run out of gas and will turn into a large elliptical galaxy.

Gemini Observatory Use New Technique for Orion Bullets Photos | New

Team of the Gemini Observatory successfully developed a technique for image object space. This time the object of shooting them is part of the Orion nebula called "Bullet Orion" (Orion Bullets).

Orion Nebula itself is a nebula that can be seen even with the naked eye. That's because the distance is relatively close to the Earth which is about 24 light-years away in the constellation Orion. Recent photos developed by researchers at the Gemini Observatory is the result of the development of image retrieval method previously called Altair. Altair is one of the instruments at the Gemini Observatory in 2007 and it used to take a photo of "Bullet Orion".

Benoit Neichel as the scientist who led the development of methods and systems of the Gemini Observatory said it was busy for a few years with the development of a new system that is possible to be able to take pictures of the sky objects more clearly. The new system called GEMS.

The result on 28 December, 3 days before the new year Gemini Observatory Bullets managed to photograph the nebula with stunning results. Her picture was 2.5 times and 16 times finer details.

To see the difference Orion Bullets photo taken in 2007 to 2012, you can see below:

ESA Herschel Telescope recognize Owned | New

Herschel telescope which is also known as the Herschel Space Observatory is a large telescope made ​​and operated by the European Space Agency (ESA) which aimed to observe the process of the formation of galaxies in the universe, the evolution of galaxies, star formation and the interaction between

stars, the chemical composition of the atmosphere and the solar system, including planets, comets, and the moon, and to know the chemical composition of molecules in the universe. Herschel telescope was launched into space on May 14, 2009 from the Guiana Space Centre, France using the Ariane 5 ECA rocket.

Herschel telescope weighs 3,300 kg (3.3 tons) and is equipped with a giant mirror of 3.5 meters that is sensitive to infrared light and wave submilimeter (55-672 m). The telescope was placed at a distance of 1.5 million km from Earth.

The telescope is named after Herschel as a tribute to the discoverer Sir William Herschel infrared spectrum and planet Uranus. Herschel telescope is able to see the object space with the coldest temperatures in the area covered by the cosmic dust though. This telescope is able to collect light from the objects in the solar system that are billions of galaxies even light years from Earth. Light collected by the giant mirror was then focused on the three detectors were stored at a temperature of -271 degrees Celsius. The detector is cooled by as much as 2,300 liters of helium. So it is that determines the helium operational lifetime of the Herschel telescope. If helium is exhausted then the Herschel telescope mission ends

Right on 29 April 2013, Helium as coolant Herschel telescope detectors in the telescope out and stop operating. ESA engineers decided to put it in orbit the Sun.

During operation, telekop Herschel has done at least approximately 35 thousand scientific observations and collecting more than 25 thousand hours of scientific data. The success of such missions successfully determine cause of it by water on planet Jupiter which was caused by the comet Shoemaker-Levy 9 in 1994, managed to find galaxies HFLS3 and other successful series of observations.

Currently ESA is preparing the next generation of the Herschel telescope SPICA.

Create admire Hubble Telescope: Extreme Deep Field


Create admire Hubble Telescope: Extreme Deep Field | New

Hubble space telescope could arguably be one of the best telescopes belong to the human race to date. Photos of the beauty of the universe objects taken using this telescope often make us wonder. One of them is a photo called Extreme Deep Field or abbreviated

XDF.Hubble XDF is a photo of a tiny spot in the sky that its contents about 5,500 galaxies. Its location is the center of the photograph Hubble Ultra Deep Field in the constellation Fornax, a small constellation in the southern sky near the constellation Eridanus and Cetus. XDF is created thanks to the Hubble telescope performance for 10 years, a total observation time of 50 days, 2 million second exposure time (exposure time), and 2,000 photos combined.

In the photos XDF, almost all the points that are visible are a galaxy. Ranging from spiral galaxies like the Milky Way and Andromeda, until the red galaxies in which there is no more the process of star birth. The characteristics of object in the photo is a point that has the 6 pillars of light into a corner, for example, are objects in the right-middle-bottom.

According to the news release accompanying the photo on September 25, 2012 and it recorded the most distant galaxies in the XDF is 13.2 billion light years. Because of the age of the universe (based on the latest research) is 13.7 billion years old, then the galaxy is about 450 million years old. Compare with the Sun and the solar system 4.5 billion years old.
Perbandingan XDF dan Bulan (Sumber: hubblesite.org)
XDF comparison and Moon (Source: hubblesite.org)Before Hubble telescope began operation in the early 1990s, we could only see galaxies as far as 7 billion light-years away. Earth-based observations is limited by the presence of the atmosphere, which just passed the visual light and radio waves from space to the Earth's surface. Hubble telescope was finally able to widen the distance limitations to be almost 2-fold. But the next few years we will probably enjoy more spectacular photo again from James Webb Space Telescope.James Webb Space Telescope, scheduled for launch in 2018, will be directed to the same point with the XDF. Because sensitive in the infrared wavelength region, this telescope will be able to record a galaxy that is located further away from the existing XDF. It's interesting to wait.This article has been discussed in dadc twitter account some time ago:

    
- Goodnight twips. dadc want to discuss one of the best photos from hubble telescope ya. called extreme deep field # xdf

    
- Hubble # xdf is a photo of a tiny spot in the sky about 5500 galaxies contents!

    
- The farthest galaxies in photo # xdf it is 13.2 billion light years. whereas the age of the universe is 13.7 mtc!

    
- So galaxies are visible in photo # xdf it only lasted for 450 million years, since the formation of the universe / big bang

    
- Wonder how can the hubble take some photo # xdf which contains galaxies as far and as weak as that? gini how:

    
- Hubble focus to a single point in the sky is dark. photograph at that point the data recorded for 10 years.

    
- In total, hubble spent 50 days and get the exposure time / exposure time of 2 million seconds!

    
- And there are more than 2,000 photos were combined to produce # xdf

    
- Let ga curious, see first picture # xdf http://hubblesite.org/newscenter/archive/releases/2012/37/image/a/format/web_print/

    
- In the photo, all the points are galaxies! except with a rounded point spike in the bottom-right, it is a star # xdf

    
- Before # this xdf, hubble ultra deep field has photo # HUDF and hubble deep field. # Xdf is a central part of the # HUDF

    
- A few more years there will probably be a more sophisticated picture, with better depth # xdf

    
- James webb telescope sensitive in the infrared region will be directed also to # xdf order to see the much fainter galaxies again

    
- If the current # xdf wrote already cool, the telescope captured jw definitely cool again later. worth the wait!
