Although both images seem to be different visions, the truth is that they belong to the same celestial body. This is NGC 1850, the star cluster discovered by the Hubble Space Telescope and the latest postcard from deep space. Two images that, though incomparable, They tell us the same reality in two different portraits.
Where do the different colors of NGC 1850 come from? As NASA explains on its website, “Different filters with different assigned colors were used to study specific wavelengths of light coming from these objects.” Thus, we know that the star cluster does not have these colors in reality. For Hubble, this is a unique way to interpret and evaluate the results in more detail..
A star cluster is a spherical formation made up of millions of stars. They are all tightly packed by a mutual gravity that holds them together. Nonetheless, the cluster NGC 1850 observed by Hubble is an anomaly in most star clusters., due to the youth of its stars. Clusters with such characteristics have not been found in our galaxy.
NGC 1850 is about 100 million years old. It is located in the Large Magellanic Cloud, a satellite galaxy of our Milky Way.. This place is also home to billions of stars. From here they hatch from their shell of dust and gas to become stars over aeons.
What do Hubble images of NGC 1850 mean?
Image with blue nebula, for its part, allows you to see visible light and near infrared light. This gives a result closer to what we could only observe with the eye. However, near-infrared detection also reveals details that might be obscured by stellar gas or dust.
As for the reddish image, it covers a much wider range. Namely, from the near ultraviolet to the beginning of the infrared spectrum.. In this way, Hubble can detect light from the hottest and youngest stars, capturing them in stunningly detailed photographs.
The mass of NGC 1850 is about 63,000 times that of the Sun, and the diameter of its core is about 20 light-years. Astronomers have used Hubble Space Telescope observations over a wide range of wavelengths to photograph this large star cluster and learn more about star formation.

More about the star cluster
NGC 1850 is a star cluster full of surprises. In 2021 Scientists have discovered the presence of a black hole inside, according to NASA. There are also a large number of blue stars that can be seen to the right of the reddish image taken by Hubble. These stars will die earlier and have hotter surfaces than red stars.
Secondly, in a cluster of about 200 giant red stars.. They have run out of hydrogen at their centers, so they fuse hydrogen farther from their core with expanding outer layers that subsequently cool and glow red. They appear all over the second image.
As the last detail we have a nebula model. Product of dust and gas from supernova explosions. Thus, these colossal structures were formed, which give a mystical appearance to these celestial bodies.
