Astronomers Witness Birth of a Powerful Magnetar (2)

Topic: Space

Researchers detected an X-ray flash that lasted 10 minutes. They think it might be the birth of a magnetar, a powerful object created when two neutron stars collide.

Astronomers have long used brief bursts of gamma rays to find collisions between neutron stars. These flashes are very short-lived, disappearing in less than two seconds. Now, new research suggests that some neutron star mergers may also produce X-ray flashes that last much longer.

The study was published in Science Bulletin and presents strong evidence for this connection. The researchers used data from the Einstein Probe satellite, which has detected hundreds of bright X-ray flashes from distant galaxies since its launch in January 2024. These events are called fast X-ray transients and have several possible origins. Some are connected to massive stars dying, while others remain unexplained.

The team led by Professor Eleonora Troja's group obtained observations that helped identify the source of one such X-ray transient. They used several instruments, including the European Southern Observatory's Very Large Telescope (VLT) and the Very Large Array. By studying what remained after the explosion, they concluded that they may have witnessed the formation of a magnetar produced by the collision of two neutron stars.

Neutron stars are extremely dense objects left behind when massive stars die. When two neutron stars merge, they generate gravitational waves that travel through space. The light produced during these events can help astronomers determine what survives the collision.

Why It Matters

This discovery helps us understand how powerful objects like magnetars are formed in the universe. It also shows how scientists use advanced technology to study distant events and learn more about the cosmos.

Key Facts

• Astronomers detected an X-ray flash that lasted 10 minutes, which might be the birth of a magnetar.
• The event was detected by the Einstein Probe satellite on July 4, 2025.
• Neutron stars are extremely dense objects left behind when massive stars die.
• Magnetars are rapidly spinning neutron stars with huge magnetic fields.
