What it is : Sagittarius C ( Sgr C ) region of theMilky Way .
Where it is:25,000 light - old age from thesolar systemin the constellation Sagittarius .
The Milky Way captured by the MeerKAT radio telescope array, with the James Webb Space Telescope’s image inset.
When it was shared : April 2 , 2025
Why it ’s so particular : TheMilky Wayoften appears as a reddish , pinkish and blueish - white arc across the night sky , but this new super - tenacious picture figure of speech from South Africa ’s ground - based MeerKAT wireless telescope shows our home galaxy in a completely new way .
Colored in dingy , cyan , yellow and lily-white , the main figure — whose many bubbles of colour are remnants of supernova — span 1,000 light - eld of the Milky Way .
The newfangled wireless image help oneself to put in context of use the inset infraredimage by the James Webb Space Telescope from 2023of Sagittarius C ( Sgr C ) . This is a 44 light - yr - encompassing region about 200 light - age from the Milky Way ’s central supermassive disgraceful hollow , Sagittarius A * , where stars are being formed .
JWST ’s image discover more than 500,000 headliner , but in this Central Molecular Zone — an uttermost environment — star are not being form as quickly as astronomers expect . One grounds may be the impregnable magnetized fields around that supermassive grim maw , which are mold the filaments ascertain by MeerKAT and JWST . These magnetic flying field may also be strong enough to resist the gravity that causes slow clouds of gas pedal and dust to break down to create stars , thus suppressing star shaping in Sgr C.
— James Webb scope ’s scene of the Flame Nebula is a ' quantum leap ' forrard for astronomers
— Hubble rapid growth in on the glittering galaxy next door
— The last sight you see before break down on the moon
" A adult question in the Central Molecular Zone of our galaxy has been , if there is so much dense gas and cosmic dust here , and we know that stars constitute in such cloud , why are so few stars turn out here ? " saidJohn Bally , an astrophysicist at the University of Colorado Boulder and one of the principal investigator of a related paperpublishedApril 2 in The Astrophysical Journal . " Now , for the first time , we are seeing like a shot that stiff magnetic fields may play an important role in inhibit ace establishment , even at little scales , " Bally pronounce in aNASAstatement .
MeerKAT is a radio scope made up of 64 dishes in South Africa ’s Karoo region . It will finally form part of a far large radio scope called the Square Kilometre Array , the world ’s big and most sensitive radio telescope that will also use more than 130,000 Christmas tree - shaped antennas on the traditional Land of the Wajarri Yamaji , in Murchison , Western Australia .
