Ursa Major , the Tadpole Galaxy , the Crab Nebula — when it comes to naming object in space , it sometimes seems like astronomers wish they ’d endure into zoology . keep on in this long custom , a investigator has latterly identified mammoth tower - determine complex body part carved from gas and rubble that he has called Giant Elephant ’s Trunks .
even - size of it astronomical Elephant ’s tree trunk are well - studied entities . When newborn star are young , they breathe colossal amounts of radiation , which can gnaw nearby interstellar gas and dust . obtuse pocket of textile are more resistant to this eating away , protecting downstream flatulency and dust from the radiation pressure and creating tenacious filaments that resemble pachyderm proboscises , according to NASA .
The Giant Elephant Trunks found in two spiral arms of the Milky Way are between 65 and 160 light-years across and may be 10,000 solar masses. It’s not clear yet what forms them, but it’s possible that these are the sites of large-scale star formation in the galaxy.

Famous instance of such bodily structure include the Horsehead Nebula and the Elephant ’s Trunk Nebula , as well as the highly photogenicPillars of Creationfound in the Eagle Nebula . Researchers often look into Elephant ’s Trunks because they are the website of star birth and other organic evolution .
Using data from a survey of the plane of theMilky WayGalaxy conduct by the Nobeyama 45 - meter Radio Telescope in Japan , uranologist Yoshiaki Sofue spotted three Elephant ’s Trunks in two pocket-size spiral limb 15,000 to 22,000 light - years away , known as the Scutum and Norma arms . They were at least an order of magnitude great in size and mass than previously seen entity .
Ordinary Elephant ’s Trunks are generally a few wakeful - years across and perhaps 10 time the mass of our sunlight . Sofue observed three objects between 65 and 160 clear - geezerhood long , each count around 1,000 to 10,000 times the mass of the sun . Apaper describing the discoveriesis set to come out in the Publications of the Astronomical Society of Japan .
Because the smaller column - shaped structures are cradles for newborn hotshot , Sofue told Live Science that the Giant Elephant ’s bole could be created by big - scale star establishment activity in the beetleweed . Perhaps they are region from which spherical accumulation of humble stars rise up , he suggested .
Now that he has trumpet these finding , Sofue say he would like to conduct a systematic review of his data in the hopes of uncover more Giant Elephant ’s body and listing them in an astronomical atlas for other researcher to study .
