如果你知道往哪里看，你可以看到一颗白矮星的热核爆炸。可能是两个。这样的爆炸被称为新星，目前在地球的南半球用肉眼可以隐约看到爆炸，但用双筒望远镜更容易看到。这张照片是上周在靠近银河系中央平面的狼星座南部拍摄到的新星Lupi 2025 （V462 Lupi）。新星Lupi 2025最初是在6月12日发现的，大约一周后亮度达到顶峰。同样的，在船帆星座（船帆）南部方向的新星Velorum 2025也于6月25日被发现，并在几天后达到峰值。每隔一两年，我们银河系的某个地方就会有一颗新星被肉眼短暂地看到，所以同时看到两颗新星是很不寻常的。与此同时，人类在等待一颗不同的新星：北极星T冠状星云，它应该在北方的天空中可见，预计会变得更加明亮。

If you know where to look, you can see a thermonuclear explosion from a white dwarf star. Possibly two. Such explosions are known as novas and the detonations are currently faintly visible with the unaided eye in Earth's southern hemisphere -- but are more easily seen with binoculars. Pictured, Nova Lupi 2025 (V462 Lupi) was captured toward the southern constellation of the Wolf (Lupus) last week near the central plane of our Milky Way galaxy. Nova Lupi 2025 was originally discovered on June 12 and peaked in brightness about a week later. Similarly, Nova Velorum 2025, toward the southern constellation of the Ship Sails (Vela), was discovered on June 25 and peaked a few days later. A nova somewhere in our Galaxy becomes briefly visible to the unaided eye only every year or two, so it is quite unusual to have two novas visible simultaneously. Meanwhile, humanity awaits even a different nova: T Coronae Borealis, which should become visible in northern skies and is expected to become even brighter.
