Located 20,000 light-years away in the constellation Carina, the young cluster and starforming region Westerlund 2 fills this cosmic scene. Captured with Hubble’s cameras in near-infrared and visible light, the stunning image is a celebration of the 25th anniversary of the launch of the Hubble Space Telescope on April 24, 1990. The cluster’s dense concentration of luminous, massive stars is about 10 light-years across. Strong winds and radiation from those massive young stars have sculpted and shaped the region’s gas and dust, into starforming pillars that point back to the central cluster. Red dots surrounding the bright stars are the cluster’s faint newborn stars, still within their natal gas and dust cocoons. But brighter blue stars scattered around are likely not in the Westerlund 2 cluster and instead lie in the foreground of the Hubble anniversary field of view.

位於距離地球20,000光年的卡拉（Carina）星座中，年輕的星團和星際形成區域Westerlund 2填滿了這幅宇宙場景。這幅令人驚嘆的圖像是用哈勃太空望遠鏡（Hubble Space Telescope）的相機拍攝的，結合了近紅外線和可見光，並慶祝其於1990年4月24日發射25週年。該星團的明亮、大質量的星星密集分佈，寬約10光年。這些年輕巨星強烈的風和輻射雕塑並塑形這個地區的氣體和塵埃，形成指向中心星團的星際形成柱。圍繞著亮星的紅點是星團內仍在其出生氣體和塵埃繭中的微弱新生星。但散布在周圍的較亮藍星則可能不在Westerlund 2星團內，而是位於哈勃紀念場景的前景。
