Hubble's observations also paved the way for future instruments. M74 was one of the first targets of the new James Webb Powerful Space Telescope
This stunning image from the Hubble Space Telescope shows the arms of the spiral galaxy M74 studded with pink regions of new star formation. M74 — also known as the Phantom Galaxy — is located around 32 million light-years from Earth in the Pisces constellation, and is a familiar sight for Hubble.
What appear to be beautiful reddish blooms scattered around M74 are actually huge clouds of hydrogen gas. They glow because of UV radiation from young, hot stars embedded in them. These regions—which astronomers call H II regions—mark where many new stars form, and are an important target for telescopes both in space and on the ground. Hubble's Advanced Surveying Camera, which collected the data in this image, even has a filter specially tuned to pick out just that particular red wavelength!
A group of observations studying the evolution of local spiral galaxies like M74 provided the data for this image. This investigation aims to gain insights into the history of star formation in these spirals. To do this, astronomers analyzed star clusters to date the different parts of spiral galaxies, and this allowed them to understand how the galaxies clustered together over time. In addition, they studied the distribution of dust in spiral galaxies. This dust is visible in this image as dark filaments winding along M74's spiral arms.
Aside from their task of understanding the history of spiral galaxies, the astronomers observed M74 to complement observations from other telescopes. Combining observations of the same object from different telescopes in the electromagnetic spectrum provides astronomers with much more insight than observations from a single telescope. Hubble's observations also paved the way for future instruments. M74 was one of the first targets of the new James Webb Powerful Space Telescope.

Enough trolling in the comments. How much swelling and self-concentration do you need to call your thought, after your name - the "neural theory". delusional

The pissed off troll obsessively floods the comments with unrelated links, and stupid "theories".
He repeats the same things over and over again in different articles.
The discussions that used to be between the readers are sometimes swallowed up between *dozens* of obsessive responses from the same troll.
It is no longer fun to visit this site that was among the few that are normal in Hebrew in science
Father, don't give in to the troll and ask him to stop
A wondrous universe created from passive energy and time

According to neural theory, infinite space is full of passive time and energy.
That passive time rests completely and is completely cold, and is the medium that transmits light, as waves of passive time.
Passive time and energy fill the infinite space, and the matter of the stars is formed by combining quantities of passive time and energy.
In neural theory, matter is not a quantitative concept, and is seen as a physical form.
If a geometric shape is seen as a quantity of closed length containing a quantity of area, then a physical shape is seen as a combination of quantities of passive time and energy.
Quantitative material does not exist in neural theory, so it is impossible to talk about a lot of material, or a little material.
Matter is a physical form, and the concept of quantity (a lot or a little) does not apply to matter.
Therefore there is no room for a lot of gravity, or a little gravity.
In the neural theory the universe works without gravity.
Since infinite space is full of passive time and energy, in this space stars are always formed from what is in space.
When a star disintegrates, it releases into space the amount of its passive time, and its amount of energy.
