说明: 船底座新星2018未来会变多亮呢?这颗新星上星期才刚发现。虽然新星经常出现在宇宙各处,但在影像中以箭头标示,出现在美丽的船底座大星云附近,编录号为ASASSN-18fv这颗新星,在地球夜空中异常的明亮,用双筒望远镜就能在南半球的天空见到它。新星成因,通常是白矮星表面累积了来自伴星的物质,因而发生热核爆炸,但这类爆发的细节目前仍不明。在接下来的数星期之中,职业和业余天文学家都会持续监控这个不寻常的恒星爆发,看船底座新星2018会如何演化,包括它是否会增亮到肉眼可见的程度。(Nova Carinae 2018 船底座新星2018)

Explanation: How bright will Nova Carinae 2018 become?The new nova was discovered only last week.Although novas occur frequently throughout the universe, this nova, cataloged as ASASSN-18fv, is so unusually bright in the skies of Earth that it is now easily visible through binoculars in the southern hemisphere.Identified by the arrow, the nova occurs near the direction of the picturesque Carina Nebula.A nova is typically caused by a thermonuclear explosion on the surface of a white dwarf star that is accreting matter from a binary companion, although details of this outburst are currently unknown. Both professional and amateur astronomers will be monitoring this unusual stellar outburst in the coming weeks, looking to see how Nova Carinae 2018 evolves, including whether it becomes bright enough to be visible to the unaided eye.
