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.

NASA's Spitzer Space Telescope will be closed.

NASA briefly informed that the Spitzer Space Telescope will be permanently discontinued on January 30, 2020. After about 16 years of discovering the universe in light energy.  And by that time, the space shuttle has been working for more than 11 years beyond its prime mission, Spitzer examines the universe's various objects in infrared light.  It was in 2003 through the rocket that the American Space Research Organization NASA entered the space and entered the orbit around the Earth.  Spitzer rotates the sun on a path similar to that of the Earth but it runs a bit slower.  Today it is about 158 ​​million miles (254 million kilometers) away from our planet - more than 600 times the distance between Earth and Moon.  The spacing of Spitzer's orbit curve means that when the spacecraft indicates its fixed antenna on the earth to download data or receive commands, its solar panels tend to lean away from the sun.  During those periods, to operate the space shuttle, one should rely on…

SpaceX is launching its next dragon spacecraft.

SpaceX is preparing for its next mission, very soon Spacex will launch the Dragon Spacecraft with its Falcon 9 Rocket.
  SpaceX is the 18th commercial reproduction service mission, dragon spacecraft will be loaded with dozens of experiments made in space.  Launch date: Sunday, July 21, 2019 at 7:35 pm  International Space Station (ISS) us  The National Laboratory SpaceX's dragon is giving a finalization to more than two dozen payloads for launch in a circular circular laboratory.  Many of these payloads are aimed at improving human health on the earth, many of which are focused on drug development.  In addition, a series of payloads from identified private sector partners will be launched on this mission.  More than 40 student experiments and demonstrations have been included on the 18th Commercial Recepti Services Mission (CRS-18) of SpaceX.  One part of ISS American National Laboratory's goal is to encourage and engage next generation scientists.                              …

SpaceX,Dragon Cargo Returns Mission in Pacific ends with SplashDown

SpaceX dragon cargo spaceship dropped at 5:48 pm in the Pacific Ocean.  The EDT (2:48 p.m. PDT) is located approximately 202 miles southwest of Long Beach, California, which is located at the end of the company's 17th contracted Cargo Resipulli mission for NASA.  Spacecraft returned more than 4,200 pounds for other valuable scientific uses. Some scientific investigations of Dragon's return to Earth include: Overview of protein crystals growth, in the use of NASA's biophysics-6, to be interested in cancer treatment and radiation safety  There has been an increase in the growth of two proteins.  Scientists are using ground-based predictions and X-ray crystallography in space to determine that proteins are beneficial in crystallization in microbiology, where some proteins can grow with big and small flaws.Microglio biosynthesis in M…
