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, Reuters reported.

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, opens new tab.

“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.

Crown Prince Mohammed bin Salman launched a new company to develop and manage artificial intelligence technologies in Saudi Arabia on Monday, a top priority of its economic diversification drive, Reuters reported.

U.S. President Donald Trump travels to Saudi Arabia this week, the first stop on his Gulf tour, and AI is expected to be a major discussion point during Tuesday’s joint Saudi-U.S. investment forum in Riyadh.

The kingdom, the world’s biggest crude exporter, is undergoing a significant economic and social transformation under its Vision 2030 programme which aims to wean the economy off its oil dependency.

It wants to develop AI technology and infrastructure – including data centres – and has ambitions to establish the kingdom as a global centre for AI, pitching itself as a prospective hub for AI activity outside the United States, read the report.

Chaired by bin Salman, Saudi Arabia’s de facto leader, the new company, Humain, will operate under the Public Investment Fund, and offer AI services and products, including data centres, AI infrastructure, cloud capabilities and advanced AI models, the state news agency reported.

Earlier this year, cloud software seller Salesforce (CRM.N), said that it planned to invest $500 million in Saudi Arabia related to artificial intelligence.

Skype officially shut down on Monday. The closure comes after nearly 22 years in operation, during which Skype became known for making international voice and video calls accessible and affordable for millions of people worldwide.

Microsoft acquired Skype in 2011 and says the decision is part of a strategy to focus on its other platform, Microsoft Teams.

Launched in 2003, Skype quickly became a revolutionary tool for free voice and video calls over the internet, amassing more than 300 million monthly users at its peak in the mid-2010s. The free platform changed how people communicated across borders, long before Zoom or FaceTime.

In 2011, Microsoft acquired Skype for $8.5bn, aiming to make it a central part of its communications strategy. But as competitors like WhatsApp, Zoom, and eventually Microsoft’s own Teams gained traction, Skype’s popularity faded.

On February 28, Microsoft said it would retire Skype on May 5 to streamline its services and prioritise Teams for communication and collaboration.

Microsoft has urged users to transition to Teams by visiting skype.com and utilising the “Start using Teams” feature. All Skype chats and contacts will remain accessible through Teams using the same login credentials.
