Is réaltra lionsach i dtreo na ciumhaise é NGC 4570 atá suite timpeall 57 milliún solasbhliain ón domhan^[5] i réaltbhuíon na Maighdine.^[6] D'aimsigh an réalteolaí Gearmánach William Herschel NGC 4570 ar 13 Aibreán 1784^[7] agus is ball de Bhraisle na Maighdine é.^[8]^[9]

Struchtúr

Tá diosca núicléach ag NGC 4570 a shíneann thart ar 330 solasbhliain ó lár an réaltra. Tá bearna thart ar 330 solasbhliain ar fad idir imeall amuigh an diosca núicléigh agus imeall istigh an phríomhdhiosca.^[10] Trí bhreathnuithe ar na braislí cruinneogacha timpeall NGC 4570, aimsíodh cuid mhaith acu atá idir 1 billiún agus 3 billiún bliain d'aois. Aisteach go leor, is cosúil go bhfuil aois mheasta na mbraislí cruinneogacha óga ag teacht go maith le haois mheasta na réaltaí sa diosca núicléach (≤2 billiún bliain). Tugann sé seo le tuiscint gur cruthaíodh na braislí cruinneogacha óga agus an diosca núicléach ó theagmhas cumaisc nó fuillimh a raibh méid mór gáis ann, agus a spreag réaltphléasc láidir sa réaltra.^[11]

Aimsíodh thart ar 120 braisle chruinneogach timpeall NGC 4570. ^[12]
