The ghostly green glow at the very top of this image reveals the presence of 46P Wirtanen – a relatively small comet with an estimated diameter of 1.2 kilometers. Had the path of history taken a different course, we would ...
Barely visible to the naked eye, Comet 46P/Wirtanen keeps some secrets so close that only radar can uncover them.
As the brilliant comet 46P/Wirtanen streaked across the sky, NASA telescopes caught it on camera from multiple angles.
As comet 46P/Wirtanen neared Earth on December 2, astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) took a remarkably close look the innermost regions of the comet's coma, the gaseous envelope around ...
Astronomers are being treated to an exciting view of Comet 46P/Wirtanen at W. M. Keck Observatory, with sharper-than-ever data images of this icy and rocky space visitor.
A special visitor is crossing the sky: Comet 46P/Wirtanen, sighted with telescopes and binoculars in recent weeks, is on the way to its closest approach to Earth this weekend, when it might become visible to the naked eye.
