The " once - in - a - lifetime " comet Tsuchinshan - ATLAS look like it has grown a physics - defying second stern after reaching its closest pointedness to Earth for more than 80,000 years , new photos reveal . However , in reality , the extra tree branch is a visual deception that come about thanks to the position of our major planet proportional to the naked - heart object .
Tsuchinshan - ATLAS has beenvisible to the au naturel heart over the last few weeksafter slingshotting around the sun in former September . However , it top out in brightness level over the last few Clarence Day after reaching its closest gunpoint to Earth on Saturday ( Oct. 12 ) , when it was around 43.9 million miles ( 70.6 million kilometre ) from our major planet — around 180 timesfarther away from us than the moonlight . The comet was potentially visible to billion of people across large parts of the globe .
Comet Tsuchinshan-ATLAS was spotted with a thin streak of light, known as an anti-tail, pointing in the complete opposite direction to its bright streaming tail. This photo was taken on Monday (Oct. 14).
On Sunday ( Oct. 13 ) , astrophotographer Michael Jägerphotographed Tsuchinshan - ATLASstreaking across the night sky near Martinsberg , Austria . In addition to showing the unremarkably bright rear , enhanced versions of the picture revealed the comet had a fainter streak of luminosity , known as an " anti - tail , " coming off its body in the diametrical counselling , harmonize toSpaceweather.com . On Monday ( Oct. 14 ) , Jäger captured another even clearer shot of the comet and its extra process ( see above ) and sent it to Live Science .
bear on : See Mercury ’s heavyweight , comet - like tail in stunning new mental image as it passes nigh to the sun
A comet ’s tail is made up of twinned trails of junk and gas that are muff off the comet by solar radioactivity , mean its tail always points forth from the sun .
Jäger first spotted the anti-tail in an enhanced version of this photo taken on Monday (Oct. 13).
Anti - tails , therefore , seem to defy physics because they can be point toward the sun . However , these surplus tails are not made of debris being blasted off the comet . or else , they are made from dust that has recently been leave behind by the comet in its orbital plane around the Sunday . When Earth passes through this plane , as it did over the weekend , this residual debris is illuminated by the Sunday and reflects back to Earth , giving the impression of a second nates .
Several other recent comet have also " grow " anti - tails as they pass by Earth . The most noteworthy example were the green comet C/2022 E3 ( ZTF ) , whichdeveloped an anti - shadow as it passed by Earth in January 2023 , and Comet 12P / Pons - Brooks , a.k.a . the devil comet , whichsprouted a second tail as it made its close approachin June this year .

The prospect of being able to see Tsuchinshan - ATLAS for yourself are quickly dwindle as the comet ’s brightness will soon evanesce as it moves away from Earth and back out toward the outersolar organisation . However , it should be possible to see the comet with a goodpair of stargazing binocularsor asmall telescopeover the next few days . you may find when and where it is in the night sky usingTheSkyLive.com .
There is also the possibility that a new discovered , " sungrazer " cometcould be visible to the naked centre subsequently this monthas it passes by Earth before a nigh slingshot around the Lord’s Day . However , recent observations now indicate that it could let on apart before it reaches us , Live Science ’s sister siteSpace.com reported .
