Astronomers have spotted a gigantic radio jet that stretches over 200,000 light-years! That’s twice as wide as our Milky Way galaxy! This incredible jet comes from a quasar, a powerful object in the universe, and it dates back to when the universe was just 1.2 billion years old—less than 10% of its current age. The findings were shared in a science journal on February 6.
The quasar, called J1601+3102, is powered by a supermassive black hole. This discovery is exciting because it’s the largest radio jet ever found from such an early time in the universe. Scientists believe these powerful jets helped shape the first galaxies.
Why Is This Jet Important?
Finding jets from the early universe is tough because there’s a lot of cosmic microwave background radiation that hides them. But this time, astronomers used two powerful radio telescopes to see the jet clearly, including one called LOFAR in Europe. They also used telescopes in Hawaii and Texas to gather more information, which helped them understand the quasar and its giant jet better.
Lead researcher Anniek Gloudemans from NOIRLab said, “This is the largest radio jet seen so far in the early Universe.” She mentioned that jets this big have been hard to find because of interference from cosmic radiation.
A Smaller Yet Powerful Black Hole
At the center of J1601+3102 is a black hole that’s 450 million times heavier than our Sun. While that sounds huge, it’s relatively small compared to other quasars that can weigh billions of times as much. Gloudemans pointed out that this finding shows that you don’t need an enormous black hole to create such powerful jets in the early universe, which goes against what scientists thought before.
The jet itself isn’t even, with one side being longer and brighter than the other. Scientists think something in its surroundings is affecting its shape, but they’re not sure what that is yet.
How Early Black Holes Shape the Universe
One big question in astronomy is whether early black holes could create strong jets. This new discovery shows that they could, suggesting these jets were actively changing the young universe by spreading heat, magnetism, and cosmic rays beyond their home galaxies.
Gloudemans highlighted how important this finding is: “It shows that these jets were already shaping the universe long ago!”
Astronomers now think there may be even more of these jets out there waiting to be discovered. However, detecting them is difficult because of the cosmic background radiation that often overshadows their signals. Thanks to new telescope technologies, scientists hope to find more of these hidden giants. Discovering more of these radio jets can help us understand how black holes and galaxies formed over billions of years.
Gloudemans expressed excitement about the discovery: “There are around 1,000 known quasars from this time and even earlier in the universe, so while they are rare, we definitely know many of them. Jets have been found even earlier, but never this large!”
This discovery is a key step in understanding our universe’s early days. The research team plans to study J1601+3102 further to learn what conditions led to the creation of such enormous jets. Each discovery brings us closer to understanding how black holes and galaxies evolved in the first billion years after the Big Bang.
