Since the first black hole photo in human history was screened on major social media, the public's curiosity and enthusiasm for the mysterious and vast universe was rekindled overnight.

Beyond the dome that mankind looks up to together, there are countless unsolved mysteries. Its mystery, vastness, complexity and unrepeatable beauty all exude infinite charm, attracting human beings to explore her from ancient times to the present.

The truth of the universe is not only the motivation of scientists' lifelong struggle, but also the sacred muse of many artists, who spend years just to present us with the magnificent picture of outer space in the most authentic way.

This time, Shanshan will take you to see the Xinghai outside the dome with the lens of an astronomical photographer.

Matt Harbison, an astrophotographer, took 5 years to take 2,508 photos. After 500 hours of editing and 42 hours of composition, he finally realized his dream that he started seven years ago: to take a 2.5-megapixel photo of Orion in 2020, showing the clearest details of Orion in great detail.

This great pioneering work was named "Orion Project" by Harbison. He made extraordinary efforts to provide one of the most detailed images of Orion in history, all of which originated from his childhood curiosity.

Harbison was deeply attracted by the Orion nebula since he was a child. He first observed the Orion nebula through a telescope when he was a boy scout. Many years later, he used the latest breakthrough of computer technology and digital photography to buy a QHY 16200 CCD monochrome camera for nearly $5,000, creating this immortal image for one of the most important landmarks in the night sky.

We can imagine that it takes hundreds of nights to take thousands of constellation photos. In search of dark skies and sunny weather, Harbison traveled through five states.

Even if all the photos are taken and every negative is taken (more than 200 in total), the final image mosaic is not smooth because it is a huge technical challenge.

It will take five years for the technology at that time to catch up with Harbeson's demand, because he won't have a powerful computer to complete this task until August 2020.

The final 44TB data of this project is stored in 2 1 hard disk, 7 notebook computers and 4 desktop computers.

But in the end, Harbeson proudly announced that the Orion project was successful in 2020 10.

Now, people can browse the website of Orion Project, zoom in and move the details of this photo at will, observe this starry sky carefully in their leisure time, and reveal the mysterious nebula The Secret Behind.

Harbeson believes that the final result is not only the strength of science, but also the presentation of art.

Some details of this huge photo after amplification, zhen beauty call way:

Two weeks ago, China's Chang 'e-5 probe successfully landed on the moon again, trying to bring back lunar rock samples to Earth. On the same day, an astronomical photographer in Utah, USA, took a photo of "Eye of the Moon". When the full moon passed through the sandstone arch millions of years ago, you couldn't help but smile: Who is watching who?

60 million light-years away, facing the southern constellation Ursa, two large galaxies are colliding. In this snapshot of the Hubble Space Telescope, it took hundreds of millions of years to capture the wreckage of the space train with amazing details.

These two galaxies are named NGC 4038 and NGC 4039 respectively, but individual stars in these two galaxies do not often collide directly. However, their macromolecular gas and dust clouds will trigger intense star formation events near the center of the wreckage. Under the action of gravity, new star clusters and interstellar matter are thrown out of order, away from the scene of the accident.

In this Hubble close-up image, the estimated distance of colliding galaxies is about 50,000 light years. In a wider field of vision, their suggestive visual appearance-extending the arc of the structure by hundreds of thousands of light years-gives the pair of galaxies a widely known name: tentacle galaxy.

M63 was identified as a typical spiral galaxy in the early stage, and it was one of the 14 spiral galaxies discovered in 1960s. However, in recent years, astronomers have found that it has the characteristics of curl.

Two months ago, the National Radio Observatory (NRAO) also announced the best astronomical image award in 2020. Let's see how scientists can bring those mysterious galaxies closer to us through artistic means!

(The following explanations of the contents of the pictures are all from NRAO. Although there are a lot of terms, astronomers have made great efforts to communicate with us in "normal language". If you are interested, you can watch the rising posture. If you are really dizzy, enjoy the pictures! )

The most energetic event in the universe is the collision between clusters of galaxies-this collision forces huge hot gas mixing between galaxies.

Through the accurate computer simulation of these events, we can compare our universe model with the real telescope observation results. These events occurred on the time scale of billions of years, and the shock wave they produced could be as high as 6 million light years.

When these impacts pass through the diffuse magnetic field in the almost empty space between galaxies, a large number of radio emissions will be produced, and a spectacular scene called "radio relics" will be presented to us.

This is a composite image of VLA and Hubble Space Telescope, revealing the expanding magnetic field of NGC 5775 galaxy.

In the optical data of the Hubble Space Telescope, the spiral disk contains hot ionized bubbles (magenta) produced by newborn stars. The fast-moving charged particles produced in these bubbles-called cosmic rays-are transported away, forming a so-called "radio continuous halo", which is shown here as a faint, ghostly blue-gray light. Some cosmic rays will be captured by magnetic field lines. These lines are represented by "streamline" (line integral convolution algorithm is converted from radio polarization vector).

The magnetic field lines begin to be parallel to the disk (marked purple in this area), and then bend outward until they are vertical. In this higher region (allocated as blue), the largest extended feature can be traced back to 26,000 light years-a quarter of the diameter of the Milky Way! By studying the magnetic field structure and radio continuous halo of NGC 5775 and other galaxies, astronomers hope to determine the origin of magnetic fields in disk galaxies and how they cause changes in the characteristics of spiral galaxies over time.

Perseus cluster is 250 million light years away from the Earth, and it is the gathering place of hundreds of relatively close galaxies. In this image, two bright giant elliptical galaxies stand out: NGC 1275 (middle left) and its sister galaxy NGC 1272 (middle).

Like many galaxies, there is a powerful supermassive black hole hidden in the center of NGC 1272. This black hole is like an engine, providing power for relativistic particle jets propagating outside the galaxy. These particles are immersed in a magnetic field and emit light in the radio band (wavy orange-red band in the figure).

These jets span at least 200,000 light years (twice the size of the Milky Way), and the particles in them are captured in a complex arrangement, including rotating eddies, narrow curved channels and spiral spirals.

Seeing the picture of the vast universe in front of me, I think of 1 the voyager1which set foot on the journey in 1977, and the famous dim blue dot-"one last look at the familiar home".

Voyager 1 launched on1September 5, 977;

198 1 year, flying over Saturn;

1986, it flew over Uranus;

1989, it flew over Neptune. ...

As he was about to fly to the edge of the solar system, carl sagan, an American astronomer, tried his best to persuade NASA to turn the camera around before Voyager/Kloc-0 ran out of fuel and look back at the Earth 6.4 billion kilometers away for the last time.

At the moment when the photo was taken, the sun just shone on the metal of the spacecraft, and the earth was buried in this beam of metal reflected light, which was extremely dim, as small as 0. 12 pixel in the photo.

After this photo was sent back to the earth, it caused a great sensation-6.4 billion kilometers away, the beautiful blue planet where we lived for generations turned out to be like this-a dim blue dot.

Carl sagan in his popular science book "dim blue dot" said with emotion:
