在天空中，有些神奇的事情正在發生！當一顆白矮星爆發時，它會產生叫做nova的閃亮光芒。我們最近看到的兩顆nova分別叫做Nova Lupi 2025和Nova Velorum 2025。Nova Lupi 2025在6月12日發現，約一周後變得非常明亮，而Nova Velorum 2025在6月25日被發現，也在幾天之後達到最高亮度。這樣的nova每一兩年才會出現一次，而最近卻有兩顆同時可見，真是難得！另外，還有另一顆nova，叫做T Coronae Borealis，預計也會在北方的天空中變得更加明亮，讓人非常期待！
原文:
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.
