NASA has released An astonishing new map of the universe, The agency says this could help scientists solve some of these Long-standing mysteries of the universe,

taken using The agency’s SPHEREx space telescopeThe first all-sky map simulates the instrument’s three-dimensional view of the sky, including burnt red cosmic dust, electric blue hydrogen gas and white, blue and green. Stars,

Panoramic view using binoculars captures these and dozens of other colors ability to see infrared wavelengths of lightWho are invisible to the human eye,

The colors allow astronomers to measure the distances to millions of galaxies from the telescope, plus the three-dimensional view of the map measures how the captured galaxies are distributed throughout the universe. red galaxies are more distant And closer ones appear blue when light is stretched or retracted, a phenomenon known as “redshift.”

Scientists will use this data, collected since the launch of the telescope into low-Earth orbit in March, to study how galaxies have changed over the universe’s nearly 14 billion-year history and potentially learn more about how the key ingredients for life were formed in our Milky Way galaxy.

NASA's SPHEREx mapped the entire sky in 102 infrared colors to reveal different features of the universe. This panoramic view shows blue stars and hydrogen gas, green and white stars and red cosmic dust.

“Despite not being visible to the human eye, these 102 infrared wavelengths of light are prevalent in the universe, and observing the entire sky in this way enables scientists to answer big questions,” NASA explained in a statement. release“It also includes how a dramatic event that occurred just a billionth of a trillionth of a second after the Big Bang affected the three-dimensional distribution of billions of galaxies in our universe.”

While the James Webb Space Telescope can also see in infrared light, its field of view is thousands of times smaller.

To date, no mission has mapped the entire sky in as many colors as SPHEREx.

The SPHEREx telescope – also known as the “Spectro-Photometer for the History of the Universe, the Age of Reionization and the Ice Explorer” – is currently orbiting about 400 miles above Earth.

It orbits Earth about 14.5 times a day, taking about 3,600 photographs along a circular swath of the sky, and constantly turning to capture the entire sky in 360 degrees.

It will complete three more all-sky scans during its two-year mission, collecting data on more than 450 million galaxies and more than 100 million stars in the Milky Way.

“SPHEREx is a medium-sized astrophysics mission that delivers big science,” said Dave Gallagher, director of NASA’s Jet Propulsion Laboratory. “This is an unprecedented example of how we turn bold ideas into reality, and in doing so, unlock the immense potential for discovery.”
