Astronomers Spot Mysterious Bar-Formed Cloud of Iron Inside an Iconic Nebula
A particular nebula contained in the constellation Lyra holds a never-before-seen cloud of iron atoms—and researchers aren’t positive why
The Ring Nebula is a sight to behold. Positioned within the constellation Lyra, this kaleidoscopic doughnut of gasoline is the dying echo of a star not too in contrast to our solar. And in accordance with a brand new research, it additionally hosts a never-before-seen, huge cloud of iron atoms. Astronomers aren’t positive why.
The cloud, which is within the form of a bar, has barely extra mass than Mars. Astronomers noticed it utilizing the William Herschel Telescope (WHT) in Spain utilizing an optical spectrometer referred to as the WHT Enhanced Space Velocity Explorer (WEAVE). The findings are detailed in a brand new paper within the Month-to-month Notices of the Royal Astronomical Society.
“After we processed the information and scrolled by the photographs, one factor popped out as clear as something—this beforehand unknown bar of ionized iron atoms, in the course of the acquainted and iconic ring,” mentioned Roger Wesson, an astronomer at Cardiff College in Wales and lead creator of the brand new paper, in a press release.

How the bar bought there’s a thriller. The bar is situated someplace in the course of the nebula and is about so long as 500 occasions Pluto’s orbit across the solar. It’s potential that the bar might inform scientists extra about how the nebula shaped. The researchers plan to conduct a follow-up research with WEAVE to attempt to reply a few of these questions.
Astronomers don’t know why it exists, nevertheless it probably just isn’t the one considered one of its sort. “It will be very stunning if the iron bar within the Ring is exclusive,” Wesson mentioned in the identical assertion. “So hopefully, as we observe and analyze extra nebulae created in the identical method, we are going to uncover extra examples of this phenomenon, which can assist us to know the place the iron comes from.”
