In the vast universe, the relationship between star formation and the activity of supermassive black holes is drawing significant attention from astronomers. Recent studies suggest that the development and activity of supermassive black holes may influence the process of star formation in galaxies. This connection is not only crucial for our understanding of the universe but also opens a new perspective on how galaxies evolve over time.

Supermassive black holes, with masses millions or even billions of times greater than that of the Sun, are believed to exist at the center of most large galaxies. When matter falls into a black hole, it is not only pulled in but also heated, emitting extremely powerful X-rays. These X-rays can impact the clouds of gas and dust in the galaxy, causing changes in the material conditions, which in turn affect the ability to form new stars.

A study from the Herschel Space Observatory of the European Space Agency (ESA) showed that, in galaxies with highly active supermassive black holes, the rate of star formation is significantly lower compared to galaxies with less active black holes. According to Mathew Page, a researcher at the University of London, “We want to better understand how star formation and black hole activity are related.” They found that in galaxies with active black holes, star formation tends to decrease significantly, especially when the black hole emits an enormous amount of radiation (Page, M., “Herschel Space Observatory: The Impact of Active Black Holes on Star Formation,” Nature Astronomy, 2016).

An interesting example comes from studies of galaxies about 8 to 12 billion years away from us. During this period, the star formation rate was extremely high, about 10 times higher than today. NASA’s research revealed that in these galaxies, supermassive black holes emitting high-energy radiation hindered the formation of new stars. These black holes emitted a massive amount of radiation, preventing cold gas clouds from concentrating and forming new stars, leading to a decline in star formation (Bock, J., “NASA’s Insight into Active Black Holes,” Astrophysical Journal, 2018).

“We find that supermassive black holes not only brighten regions of space around them but can also halt the process of star formation,” said James Bock, a NASA researcher. “The stronger the black hole, the faster it strips away the opportunity to create new stars in galaxies.”

Gaining a better understanding of the relationship between star formation and black hole activity will help us answer many questions about the evolution of galaxies in the universe. By utilizing modern tools such as the Herschel Space Telescope and the Chandra X-ray Observatory, scientists are gradually uncovering these mysteries.

“We want to know whether this process starts when the brightest galaxies form, or whether all supermassive black holes stop star formation, with only the most powerful ones doing so more quickly,” shared Bill Danchi, a Herschel program scientist at NASA (Danchi, B., “The Evolution of Galaxies and the Role of Supermassive Black Holes,” NASA, 2019).

Exploring this connection not only helps us better understand how galaxies evolve but also opens new doors to the exploration of how cosmic forces work simultaneously. As astronomers continue to observe and study distant galaxies, we are gradually getting closer to unlocking the great mysteries of the universe.
