How galaxies transform into a shape.

A galaxy made of billions of stars and dust, gas, is so large in size that it takes billions of years for light to pass from one end to the other. This universe is another numbered galaxy, and every galaxy has its own shape  It is, some galaxies would have spiral shape, like our Milky Way. The Milky Way is spiral in shape, was it the same way when the Milky Way was formed, or was it different at that time. Now the question is, when the Milky Way was built, how did it come from its size at that time.

The Milky Way galaxy has an elegant spiral shape with long arms, but exactly how it came to be in this form, researchers have long been surprised by the size of the Milky Way. Researchers are studying another galaxy, how spiral-shaped galaxies acquire their own shape.

According to research by Infrared Astronomy and Stratospheric Observatory, magnetic fields play a strong role in shaping these galaxies. Scientists measured magnetic fields called NGC 1068, or M77, along the spiral arms of the galaxy. Fields are shown as streamlines, which closely follow the circled arms.

Enrique Lopez-Rodríguez, a University Space Research Association scientist at the SOFIA Science Center at NASA's Ames Research Center in Silicon Valley, California, says magnetic fields are invisible, but they affect the evolution of a galaxy, we can  Have a very good understanding of how gravity affects galactic structures.

The M77 galaxy is located in the constellation Cetus, 47 million light years away from the Milky Way, a spiral galaxy similar to the Milky Way, with a supermassive active black hole at its center, twice as large as the black hole at the center of the Milky Way galaxy.The arms of these galaxies are filled with rotating, dust, gas, and areas of intense star formation.Magnetic Field Alignment Extensively, the magnetic field alignment in the arms of the Milky Way extends over the entire length of the arms, up to about 24,000 light-years,Meaning that the gravitational forces that make up the spiral shape of the galaxy are also denser.Supporting the wave theory, its magnetic fields are compressed.

For the first time, researchers have aligned such large-scale magnetic fields with the birth of the current star in the spiral arms.To observe the magnetic magnetic field, SOFIA's newest tool, the high-resolution airborne wideband camera-plus or light With the ability to study galaxies, it aligns perpendicular to magnetic field lines.With these, astronomers can estimate the shape and direction of the invisible magnetic field. Especially at wavelengths of 89 μm, it can detect previously unknown aspects of magnetic fields.

To study how magnetic fields affect the formation and evolution of other types of galaxies, infrared astronomy will use a Boeing 747SP jetliner.  Modified to be carried on a 106-inch diameter telescope, NASA and the German Aerospace Center, a joint project of DLR.

The Esa / Nasa Hubble Space Telescope captured the image of cluster 47 Tucanae.

The Nasa/Esa Habble telescope has captured an image of a group of stars, spherical in shape, spanning a large area, this group of stars has billions of stars, these stars have their own color, which is much about them  It says.  In the image we can see, around 35,000 stars are visible near the center of the cluster 47 Tucanae , the stars are tightly packed near the core (top left) of the cluster, and propagate farther away from the core.

In the cluster image of stars, how stars are shown in natural colors, scientists have told about their composition and age through the color of stars, as the star which appears red, the stars end of their life. Is near, bright red signifies giants, while more common yellow stars indicate that these stars are still young, whose age is similar to our sun.

Cluster 47 Tucanae image taken by Hubble's Wide Field and Planetary Camera 2, this image was taken in 1999.

According to Nasa's report the rules protecting other planets from pollution can be very strict

Some scientists believe that the moon will have an interesting mission to seek life, with scientists also considering it as a potentially interesting site to investigate the origin of life on the Moon. But some scientists say that most of the moon is not astrologically interesting. Some places on the moon, Mars and other planets are safe, while some places are unprotected.  Some policies may be too strict to protect the Moon, Mars and other places.

What was the conclusion of NASA's 12-expert panel To review voluntary international guidelines, to keep space missions polluting other worlds with earthly life. These guidelines are recommendations of the international scientific organization COSPAR, which revised policies for spacefaring countries for decades.  Nasa will send a sample-collection mission to Mars next year, the same other space agency also lunar  Interpretation of preparing the trip, as the scientists, there is an urgent need to update safety guidelines of the planets.  A…

How did life begin on Earth? Is it possible by a violent collision on the moon.

The moon, which has many stories to make, did the violent, and cosmic collision during the making of the moon make life possible on earth? This is a big question, but a new study shows that this is true. Science has given many theories about life on earth, but there is always a question in our mind that how life came to be born on earth.Given by science, has many theories, and tries to explain to us how to find elements for life on our planet: such as carbon and nitrogen elements.
Scientists have previously believed that meteorites have brought life-giving elements to Earth, bacteria with meteorites coming from space for example, and the energy of explosions caused by the continuous fall of meteorites from organic matter.Synthesis of. And the isotopic signatures of these elements on Earth coincide with those objects, but what? The ratio of carbon to nitrogen is not very accurate.If we think of transporting the elements that are important for life on Earth due to meteorites, then each p…
