On Sept. 17, an observatory in Chile snapped a photograph utilizing a telescope, displaying SWAN25B with a vivid coma and hanging emerald ion tail. A coma is an environment that types round a comet because it nears the solar. The solar’s warmth causes the frozen gases and icy chunks within the comet’s nucleus to alter and create an environment.
“With its orbit nonetheless poorly constrained because of a really brief observational arc, this comet has shortly grow to be an enchanting goal to observe within the coming weeks,” the team in Chile said.
What precisely is a comet?
NASA calls comets “cosmic snowballs of frozen gases, rock, and mud that orbit the solar,” noting that “when frozen, they’re the scale of a small city.”

You’ll be able to track the position of SWAN25B utilizing TheSkyLive.com, which provides the comet’s distance from the Earth in actual time and affords a neat interactive star map. That map allows you to enter your location so you possibly can see what the sky seems to be like from the place you reside.
It is a lot simpler to see the comet, or any cosmic options within the night time sky, when you head away from metropolis lights and go to a darkish space within the nation.
