A new space observatory in NASA is scheduled to be launched throughout this week on a noble mission to appoint more than 450 million galaxies.
The SPHEREX Mission (briefly for the spectral scale of the history of the universe, the era of re -ionization and Explorer) will plan the entire sky four times over two years, providing scientists an opportunity to study how to form galaxies and develop, and providing a window with how the universe is.
NASA SPAREX Observatory is under BAE Systems in Bulder, Colonel, in 2024.
“He will answer a basic question: How did we get here?” Sean Domagal Goldman, Acting Director of Astronomical Physics at NASA headquarters, told a recent press conference.
The launch of the Vandenberg Space Force Base in California is scheduled to be launched on Saturday, within a window that opens at 10:09 pm Easter.
It was initially planned on February 27, but NASA renounced it several times, first to “complete the treatment of vehicles and remove prior”, and because of the availability of the California launch site.
The spacecraft will be deployed in the form of a cone-along with four satellites, the size of a bag that will at the same time on a separate sun task-at the top of the Spacex Falcon 9 missile.
The initial design of the spacecraft, including the hexagonal sunlight that will help keep cold tools.
SPHEREX mission of $ 488 million, which was under development for about a decade, was designed to assign the heavenly sky in infrared colors – more than any other task before it, according to NASA.
Infrared in space is ideal for a hole through dust and gas to see some of the oldest stars and galaxies of the universe, which can block view. (Colors in the infrared range are invisible to people because infrared light has longer wavelengths than the eye can discover.)
Using a technique called spectral analysis, scientists can divide light infrared light from stars and galaxies into different colors, similar to how the sun’s rays that strike the post into a rainbow from visible shapes. The objects of the object can reveal many useful properties, including its composition, density, temperature and movement.
Jimmy Book, the main researcher at the SPAREX mission and professor of physics at the California Institute of Technology, said that the SPAREX Observatory will use its spectrums to wipe the sky in three dimensions and measure these characteristics in hundreds of millions of galaxies.
Book said that these notes can open the answers about the formation of the galaxy and enable the observatory to investigate the origin of water and other organic materials in the Milky Way.
“When the light is divided, we can use it to determine the distance to the galaxies, to build this 3D map, and we also see the water fingerprints.”
Tracking the origins of water can not only help scientists how life develops on Earth; Work may also result in a place where the main ingredients can be found for life elsewhere in our galaxy.
“This is a new ability, and with any new ability, the possibility of discoveries and surprises comes,” said Book.
When drawing the heavenly sky, SPAREX will also deal with one of the most permanent secrets of astronomy: What happened in the first moments after the big explosion that created the universe about 13.8 billion years ago.
One of the theories, which were proposed in the late 1970s and early 1980s, indicate that the universe has undergone a noticeable trillion trillion twice in the first fractures of the second after the big explosion. Theory, known as cosmic inflation, was used to explain the flat universe engineering and a lack of bending, and as a possible reason for how some of the largest structures in the universe – galaxies and galaxies, for example -.
But astronomers have long struggled to collect what prompted cosmic inflation or why it happened in the first place. SPHEREX mission can test theory in new ways, because determining the exact distribution of hundreds of millions of galaxies would help scientists refine cosmic inflation physics and how this rapid expansion has occurred.
“What SPHEREX will do will test certain models of inflation by tracking three dimensions hundreds of millions of galaxies on the entire sky,” said Brook.
Domagal Goldman said that the SPAREX mission of galaxies, cosmic inflation and the origins of the universe could enhance the understanding of humanity of basic physics.
He said: “We are very distinguished in the long story of human existence on this planet to live at a time when we can already answer questions about the universe.”
