哈勃太空望远镜捕捉到了一张令人惊叹的星云图像，名为LDN 1471。这个抛物线形状的星云是由一颗新形成的恒星产生的恒星风吹出的空腔，恒星位于抛物线的顶端，发出明亮的光芒。恒星风与英仙座分子云中的周围物质相互作用，导致星云发光。我们只能看到空腔的一侧，另一侧被黑暗的尘埃遮挡。星云的抛物线形状是由于恒星风吹出的空腔随着时间的推移而扩大形成的。此外，在原恒星的两侧还可以看到两个赫比格-哈罗天体，它们也是恒星风与周围物质相互作用的结果。然而，空腔壁上的条纹成因仍然未知。这张图片由哈勃望远镜拍摄，最初由斯皮策太空望远镜探测到。

🔭**LDN 1471是由一颗新形成的恒星产生的星云空腔，形状呈抛物线。**这颗原恒星位于抛物线的顶端，发出明亮的光芒，其产生的恒星风与周围的英仙座分子云相互作用，导致星云发光。

🌌**空腔的一侧被黑暗的尘埃遮挡，我们只能看到其一侧。** 抛物线形状是由于恒星风吹出的空腔随着时间的推移而不断扩大形成的。

Astronomy Picture of the Day Discover the cosmos!Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.2024 November 17 LDN 1471: A Windblown Star Cavity Image Credit: Hubble,NASA,ESA; Processing & License: Judy Schmidt Explanation: What is the cause of this unusual parabolic structure? This illuminated cavity, known as LDN 1471, was created by a newly forming star, seen as the bright source at the peak of the parabola. This protostar is experiencing a stellar outflow which is then interacting with the surrounding material in the Perseus Molecular Cloud, causing it to brighten. We see only one side of the cavity -- the other side is hidden by dark dust. The parabolic shape is caused by the widening of the stellar-wind blown cavity over time.Two additional structures can also be seen either side of the protostar; these are known as Herbig-Haro objects, again caused by the interaction of the outflow with the surrounding material. What causes the striations on the cavity walls, though, remains unknown. The featured image was taken by NASA and ESA’s Hubble Space Telescope after an original detection by the Spitzer Space Telescope.
