A comet’s common run on the solar is dicey enterprise, and essentially the most promising house snowball of the yr is already feeling the warmth because it cruises towards Earth and our native star.
Comet C/2023 P1 (Nishimura) was first noticed final month by Hideo Nishimura, an newbie astronomer in Japan, utilizing solely a digital digital camera setup and a number of talent. It is set to make an in depth cross by Earth on Sept. 12 after which whip across the solar on Sept. 17 earlier than being flung again out to deep house. If it survives that lengthy.
Comet Nishimura has been assembly some severe resistance within the type of blasts of charged particles and plasma issuing forth from a tumultuous solar. Observers like astrophotographer Michael Jaeger (see above) watched Saturday as a photo voltaic storm engulfed the comet and appeared to blow a portion of its tail away for a second.
Here is a extra dramatic instance that was captured by NASA in 2007 of Comet Encke having its tail briefly stolen:
Comet Encke suffered a disconnection occasion in 2007.

“Researchers name this a disconnection occasion; It is brought on by a CME (or quick photo voltaic wind stream) hitting the comet,” former NASA astronomer Tony Phillips wrote at Spaceweather.com. “Nishimura’s tail has since grown again — but it surely may not final for lengthy. Extra CMEs are heading its manner.”
CME stands for coronal mass ejection, which is an eruption from the outer layers of the solar that usually accompanies a photo voltaic flare. Consider it as a really sturdy gust of energetic wind coursing via house and inflicting electromagnetic chaos. This is similar pressure that causes auroras to mild up the skies when it collides with Earth’s magnetic subject. It may additionally affect different issues in house, like asteroids and comets.
The solar is presently constructing towards the height of its roughly 11-year photo voltaic cycle, which implies extra frequent flares and CMEs. At the very least two extra of the ejections Phillips talked about issued forth from the solar’s corona on Tuesday, exploding within the course of Comet Nishimura.

Nishimura is a brand new comet that was found on August 11, 2023. It is anticipated to brighten to a magnitude of 1.8. Its closest strategy to us shall be on Sep 12 and its perihelion on… pic.twitter.com/BXhDo0IOpq

Learn how to catch the comet
All this tough house climate generally is a bit distressing for skywatchers hoping to see the comet with the bare eye. Though the comet continues to be approaching Earth, now could possibly be the perfect time to begin searching for it. Nishimura is predicted to be vivid sufficient to see as quickly as Sept. 8, however within the Northern Hemisphere it can seem close to the horizon, making it a bit harder to find.
“It is actually finest seen with binoculars or a telescope,” Alison Klesman, who holds a doctorate in astronomy, wrote for Astronomy.com. “However via these optics, it can dazzle.”
In different phrases, it may be simpler to identify in early morning skies with some kind of magnification, so would possibly as nicely begin wanting immediately.
Seek for the comet within the constellation Leo an hour or two earlier than dawn. You need to use apps like Stellarium, Star Stroll or TheSkyLive to assist find it.
It is very troublesome to know what the longer term holds for a comet. They will journey for hundreds of years from the sting of the photo voltaic system to make a single orbit across the solar. On the identical time they’re fragile issues with an inclination to disintegrate as they cross via the inside photo voltaic system. They’ve even been identified to crash into Jupiter or the solar alongside the best way. The dinosaurs might also have had an in depth encounter with one many thousands and thousands of years in the past.
So with all of the turbulence the solar is sending out currently, it is good to stand up early to attempt to see Comet Nishimura for your self whereas it is nonetheless holding itself collectively. Good luck!
