Astronomers spot galaxy shaped like the Milky Way but is far more massive
WASHINGTON: Astronomers have observed a galaxy dating to an earlier epoch in the universe's history that surprisingly is shaped much like our Milky Way - a spiral structure with a straight bar of stars and gas running through its center - but far more massive, offering new insight into galactic formation. The distant galaxy, called J0107a, was observed as it appeared 11.1 billion years ago, when the universe was about a fifth of its current age. The researchers used data from the Chile-based Atacama Large Millimeter/submillimeter Array (ALMA) and NASA's James Webb Space Telescope to study the galaxy. They determined that the galaxy's mass, including its stars and gas, was more than 10 times greater than that of the Milky Way, and it was forming stars at an annual rate approximately 300 times greater. J0107a was more compact than the Milky Way, however. 'The galaxy is a monster galaxy with a high star formation rate and plenty of gas, much more than present-day galaxies,' said astronomer Shuo Huang of the National Astronomical Observatory of Japan, lead author of the study published this week in the journal Nature. 'This discovery,' said study co-author Toshiki Saito, an astronomer at Shizuoka University in Japan, 'raises the important question: How did such a massive galaxy form in such an early universe?' While a few galaxies that are undergoing star formation at a similar rate to J0107a exist in today's universe, almost all of them are ones that are in the process of a galactic merger or collision. There was no sign of such circumstances involving this galaxy. J0107a and the Milky Way have some commonalities. 'They are similarly huge and possess a similar barred structure. However, the Milky Way had plenty of time to form its huge structures, while J0107a didn't,' Saito said. In the first few billion years after the Big Bang event 13.8 billion years ago that initiated the universe, galaxies were turbulent entities and were much richer in gas than those existing currently - factors that fostered extreme bursts of star formation. While galaxies with highly organized structures like the barred spiral shape of the Milky Way are common now, that was not the case 11.1 billion years ago. 'Compared to other monster galaxies in the distant universe (dating to an earlier cosmic epoch) whose shapes are usually disturbed or irregular, it is unexpected that J0107a looks very similar to present-day spiral galaxies,' Huang said. 'Theories about the formation of present-day galactic structures may need to be revised,' Huang added. The Webb telescope, as it peers across vast distances back to the early universe, has found that galaxies with a spiral shape appeared much earlier than previously known. J0107a is now one of the earliest-known examples of a barred spiral galaxy. About two thirds of spiral galaxies observed in the universe today possess a bar structure. The bar is thought to serve as a form of stellar nursery, bringing gas inward from the galaxy's spiral arms. Some of the gas forms what are called molecular clouds. Gravity causes the contraction of these clouds, with small centers taking shape that heat up and become new stars. The bar that is part of J0107a measures about 50,000 light years in length, Huang said. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). The Webb telescope 'has been studying the morphology of early massive galaxies intensely recently. However, their dynamics are still poorly understood,' Saito said.

Scientists spot high-speed galaxy collision 11 billion light-years away: 'We hence call this system the cosmic joust'
When you buy through links on our articles, Future and its syndication partners may earn a commission. Using a telescope in Chile, astronomers have captured a high-speed collision between two galaxies located more than 11 billion light-years away, getting a rare direct glimpse into how the universe's most luminous sources of energy, known as quasars, can sculpt their surroundings and influence the evolution of galaxies. The new findings describe a galactic battle between the galaxy on the right in the image above, which hosts an actively feeding black hole, a quasar, at its center, and its neighbor on the left, which is being bombarded by intense radiation that disrupts its ability to form new stars. "We hence call this system the 'cosmic joust,'" Pasquier Noterdaeme, a researcher at the Institut d'Astrophysique de Paris in France, who co-led the new study, said in a statement. Named J012555.11−012925.00, the quasar is generally so bright that it outshines its surroundings, dominating optical images as a single point of light. However, using the Atacama Large Millimeter/submillimeter Array (ALMA), a network of 66 radio dishes in the Chilean Andes working together as one giant telescope, astronomers were able to distinguish the second galaxy. The observations revealed the companion galaxy is moving toward the quasar-hosting galaxy at about 1.2 million miles per hour (2 million kilometers per hour), indicating the two are in the midst of a high-speed collision. To study how the quasar's radiation affects the companion galaxy, the researchers used the X-shooter instrument on the Very Large Telescope (VLT), also located in Chile. By analyzing the quasar's light as it passed through the other galaxy, they found the radiation blasts apart the gas in the companion galaxy, leaving behind compact cloudlets that are too small to form new stars.

The gravitational forces at play are also pulling more gas toward the black hole, allowing it to continue feeding and powering the quasar, the study found. "These mergers are thought to bring huge amounts of gas to supermassive black holes residing in galaxy centres," said Balashev. The study was published on Wednesday (May 21) in the journal Nature.
