Now that the Hubble Space Telescope is back online and working properly, it has captured some amazing images, including new stars emerging from a “star nursery” in deep space.
Hubble’s Wide Field Camera 3 (WFC3) image captured a “stellar nursery” in the constellation of Gemini, about 5,000 light-years from Earth.
The nursery, known as AFGL 5180, is made up of dust and gas and is one of the many regions of space where stars are born.

Arboretum AFGL 5180 consists of dust and gas and is located in the constellation Gemini. Gemini has two stars: Pollux (left) and Castor (right). Pollux is located 33 light years from Earth and Castor is 51 light years away
The image was taken by Hubble’s Wide Field Camera, which captures images in visible and infrared light
The image was captured by Hubble’s WFC3, which captures images in visible and infrared light, allowing young stars hiding in regions like AFGL 5180 to be seen more clearly.
How are stars formed?
Stars form from dense molecular clouds – of dust and gas – in regions of interstellar space known as stellar nurseries.
The mass of a single molecular cloud, containing mostly hydrogen atoms, can be thousands of times greater than the mass of the Sun.
They undergo turbulent motion as gas and matter move over time, disrupting atoms and molecules, causing some regions to contain more matter than others.
If a sufficient amount of gas and dust accumulates in one area, it will begin to collapse under the influence of its own gravity.
As it begins to break down, it slowly gets hotter and expands outward, absorbing more of the surrounding gas and dust.
At this point, when the region is about 900 billion miles wide, the core becomes pre-stellar and the process of becoming a star.
Then, over the next 50,000 years, this latitude will shrink by 92 billion miles to become the star’s inner core.
Excess material is ejected toward the star’s poles, and a disk of gas and dust forms around the star, forming a protostar.
This material is then either incorporated into the star or ejected into a wider disk, resulting in the formation of planets, moons, comets, and asteroids.
“Stars are born in dusty environments, and while this dust makes amazing images, astronomers can sometimes see stars in them,” NASA wrote in the NASA Journal. advertisement.
Hubble’s WFC3 instrument is designed to capture detailed images in both visible and infrared light, meaning that young stars hiding in vast star-forming regions like AFGL 5180 can be seen more clearly.
In the image, a “massive” star begins to form and its voids appear through the clouds.
NASA added that the light reaches Earth by illuminating the recesses, similar to a “lighthouse piercing storm clouds.”
The constellation of Gemini consists of two stars: Pollux and Castor.
NASA said on the site website.
Instead, Castor is 51 light-years away and is a blue main-sequence star, 2.7 times the size of the Sun.
Castor has at least two stellar companions, while Pollux has at least one “Massive Planet”.
In June, a group of cosmic cartographers mapped star nurseries and revealed just how diverse the different galaxies are in the universe.
They have studied star-forming regions in our part of the universe and mapped more than 100,000 nurseries in 90 nearby galaxies to gain insight into the origin of stars.
Stars consist of clouds of dust and gas called molecular clouds or stellar nurseries.
Each stellar nursery in the universe can form thousands or even tens of thousands of new stars in its lifetime.
Stellar nurseries live for up to 30 million years, which is a small amount of time on astronomical scales, and not very efficient at turning gas into stars.
Scientists study the atmosphere of distant exoplanets using huge satellites in space such as Hubble
Distant stars and the planets they orbit often have conditions that are different from anything we see in our atmosphere.
To understand this new world and its components, scientists must be able to discover the components of the atmosphere.
They often do this with a telescope similar to NASA’s Hubble Telescope.
These massive satellites are scanning the sky and pinning them to exoplanets that NASA thinks might be of interest.
Here, the onboard sensors perform various forms of analysis.
Of the most important and useful is absorption spectroscopy.
This form of analysis measures the light emitted by the planet’s atmosphere.
Each gas absorbs a slightly different wavelength of light, and when this happens, a black line appears across the spectrum.
These lines correspond to a very specific molecule, indicating its presence on the planet.
They are often called the Fraunhofer lines, after the German astronomer and physicist who first discovered them in 1814.
By combining all of the different wavelengths of light, scientists can identify all of the chemicals that make up the planet’s atmosphere.
The key is that what is missing provides clues to what is there.
It is very important that this is done by space telescopes, as they penetrate the Earth’s atmosphere.
The uptake of chemicals into our atmosphere can skew the sample. That’s why it’s important to study light before it has a chance to reach Earth.
This is often used to search for helium, sodium, and even oxygen in exotic atmospheres.
This graph shows how light passing from a star and through the atmosphere of an exoplanet produces Fraunhofer lines, which indicate the presence of important compounds such as sodium or helium.
