Astronomers detected mysterious high-energy ultraviolet radiation around five infant stars in the Ophiuchus star-forming region. This kind of radiation shouldn’t exist near young protostars… and yet, it does.

Could baby stars be more powerful than we thought?
Or is something even stranger going on?

Join us as we break down this cosmic mystery and explore how this discovery could change everything we know about how stars are born :glowing_star:

00:00The James Webb Space Telescope just spotted something totally unexpected.
00:04Mysterious high-energy radiation, coming from baby stars.
00:08Astronomers aimed Webb at the Ophiuchus Star Nursery, 450 light-years away.
00:12They found five newborn protostars,
00:15tiny stars still forming deep inside clouds of gas and dust.
00:18But here's the twist.
00:20These infant stars were surrounded by powerful ultraviolet radiation
00:23that shouldn't be possible.
00:25Young stars aren't supposed to produce this kind of energy.
00:28So where is it coming from?
00:30At first, scientists thought nearby, massive stars might be to blame.
00:34But even after factoring in the surrounding dust and distances,
00:37the radiation didn't match up.
00:39That's when things got really weird.
00:41Turns out, the UV light is coming from the stars themselves.
00:45Maybe from shocks around them, or from jets of gas, they violently launch into space.
00:49This discovery could change our entire understanding of how stars are born.
00:53And the James Webb Telescope is just getting started.
