Hubble has discovered a 'mysterious golden dragon' 4 billion light-years away, spanning 5 galaxies!
Dragon is a mystical animal in ancient Chinese mythology, it can fly through clouds and fog, however the golden dragon we are referring to is not this type, instead it is a natural image. strange text.
The Chinese dragon is a legendary animal. This dragon has a long snake-like shape, a body with scales like fish scales, a head like a lion's head, and four legs with claws. Dragons can fly, can spray water to create rain. For thousands of years, people have tried to find this legendary animal, but have failed, because in fact dragons do not exist at all.
However, as NASA's Hubble Telescope was observing the dark and deep space of Cetus, it suddenly spotted a bright, yellowish line in the galaxy cluster Abel 370 4 billion miles away. light year.
The Hubble Space Telescope (English: Hubble Space Telescope, abbreviated HST) is an active space telescope of NASA. Hubble is not the world's first space telescope, but it is the largest and most powerful telescope ever launched.
It was launched and operated in Earth's orbit at an altitude of about 610 km, about 220 km higher than the orbital altitude of the international space station ISS. With a speed of about 7,500 m/s, Hubble can orbit the Earth once in 97 minutes and 15 times a day. The Hubble telescope is named after the American astronomer Edwin Powell Hubble (1889-1953). This is a reflecting telescope equipped with a computer system and a light-collecting mirror with a diameter of 240 cm.
This is the Hubble Telescope's Extremely Deep Space Frontier Field and Relic (BUFFALO) observation program. When observing galaxy cluster Abel 370, scientists noticed strange distortions on the edge of the gravitational lens, so they nicknamed it The Dragon.
Abell 370 is a galaxy cluster located nearly 5 billion light-years from Earth, in the constellation Cetus. Its core is made up of several hundred galaxies. It was cataloged by George Abell, and is the most distant of the clusters he cataloged.
The galaxy cluster Abel 370 is a collection of hundreds of galaxies, each containing tens to hundreds of billions of stars, and this cluster's proportion of dark matter is thought to be extremely large, which creates a gravitational field. very big.
When the light behind the cluster passes through this gravitational field, the gravitational force is so strong that the light's path is bent, resulting in a magnifying effect known as gravitational lensing, which allows us to see see things that we normally can't see.
Hubble uses two cameras to observe two different types of light simultaneously, an Abell 370 and another that looks deep into the early universe by observing the 'parallel field', a thinner portion of the sky adjacent to it. cluster Abell 370.
These Abell 370 and parallel field observations are part of NASA's recently concluded ambitious Frontier Fields program. According to IBTimes, Frontier Fields' aim is to make the deepest observations of large galaxy clusters such as Abell 370 and the older, distant galaxies that lie behind them.
The mysterious dragon observed this time is not a real dragon but a distorted image of the Milky Way.
Scientists think they are actually five images of the same spiral galaxy, enlarged and stretched by galaxy cluster Abell 370 to form an arc that resembles the shape of a Chinese dragon.
However, some scientists previously believed that the dragon could be some galaxy about 5 billion light-years away.
In this image, the yellowish-white objects are the largest and brightest elliptical galaxies containing billions of stars. The bluish objects are spiral galaxies (like the Milky Way that contains our earth), which often contain many younger bluish stars. The mysterious arcs of blue light scattered throughout the image are distorted images of the galaxies behind the cluster Abell 370.
Abell acts as a natural lens, destroying space and governing the passage of light. through it to Earth to magnify and stretch images of these galaxies, which are too dim for Hubble. This phenomenon, known as gravitational lensing, helps diffuse distant galaxies that can only be observed with large natural lenses like the galaxy cluster Abell 370.
By measuring The Dragon's arc, scientists can track and determine the degree of distortion and radiation between these galaxies and dust, and calculate the missing dark matter mass, to understand structure of the universe and understand the deepest problems in the universe.
NASA and the European Space Agency have begun a mission to unravel the evolution of the earliest galaxies in the universe. The BUFFALO survey will observe six massive galaxy clusters and their surroundings.
Using the Hubble Telescope, a BUFFALO survey will be conducted to observe six massive galaxy clusters and their surroundings.
NASA says the mission is important because learning about the formation and growth of the first galaxies in the universe is "critical to our understanding of the universe." This will allow astronomers to determine how large galaxy clusters formed during the first 800 million years after the Big Bang.
