p>A fireball streaked across the night sky over southern Australia on Monday night, causing a sonic boom and rattling homes across Victoria.
The Australian Space Agency (ASA) said the fireball was likely the remnants of a Russian Soyuz rocket that had launched a Glonass navigation satellite earlier that day.
The Soyuz's third stage reentered Earth's atmosphere over the open ocean, southeast of Tasmania, around 10:00 AM EDT (14:00 GMT; midnight Melbourne time).
The fireball was visible for several minutes and was captured on video by many people across Victoria.
"It was amazing," said one witness. "It was like a shooting star, but much, much brighter."
The ASA said the fireball was not expected to cause any damage, but it is a reminder of the dangers of space junk.
Space junk is a growing problem, as more and more objects are being launched into space. These objects can pose a risk to satellites and spacecraft, and even to people on the ground.
The ASA is working to develop technologies to track and remove space junk, but it is a complex problem with no easy solutions.
In the meantime, people who live in areas where space junk is likely to reenter the atmosphere should be aware of the risks and take precautions.
Here are some tips for staying safe during a space junk re-entry:
