木星上有一個大“黑洞”？

Stunning new images shot by NASA's Juno spacecraft appear to show a massive black hole on the surface of Jupiter.

美國宇航局“朱諾號”宇宙飛船拍攝的令人震驚的新圖像顯示，木星表面有一個巨大的黑洞。

The photographs were taken earlier this month as Juno's elliptical orbit took it close to the gas giant - only 8000km from the top of its clouds.

這些照片是在本月早些時候拍攝的，當(dāng)時“朱諾號”的橢圓軌道將其靠近這顆氣態(tài)巨星——距離其云層頂部僅8000公里。

But rather than an abyss from which there is no escape, Jupiter's latest feature is just a shadow cast by one of its moons, Io, as it blocked the sun during an eclipse.

不過，木星的最新特征并不是無法逃脫的深淵，而是它的衛(wèi)星之一木衛(wèi)一(Io)在日食期間擋住太陽時投下的陰影。

Io is about the same size as Earth's moon. Because it's so far away, in the Jovian sky Io appears about four times the size as the sun - so its shadow is large and relatively sharp, compared to eclipses here on Earth, Universe Today reports.

木衛(wèi)一的大小和地球的月球差不多。據(jù)《今日宇宙》報道，由于木衛(wèi)一離地球太遠(yuǎn)，在木星的天空中，木衛(wèi)一的大小大約是太陽的四倍，所以與地球上的日蝕相比，木衛(wèi)一的陰影更大，也更銳利。

Last week it was reported a volcano is set to erupt on Io.

上周有報道稱，木衛(wèi)一火山即將噴發(fā)。

Jupiter's other distinctive feature - its giant red spot - is a storm that is expected to dissipate one day.

木星的另一個顯著特征——它的巨大紅斑——是一場預(yù)計需一天才會消散的風(fēng)暴。
