The VLT platform on Paranal just after sunset. The four 8.2m Unit Telescopes are ready for the night.
Taken during the ESO Ultra High Definition Expedition at ALMA Observatory, the 66-antenna ALMA array can be seen looking up towards the star-filled violet skies.
A whole group of ALMA antennas was collected on this UHD image, while they are observing the night sky.

A deep, fiery sunset at Paranal caught in this UHD panorama. ESO's VLT platform can be seen high on Cerro Paranal in shadow (left). Taken during the ESO Ultra HD Expedition.
The Milky Way glitters above the ALMA array in this image taken from a time lapse sequence during the ESO Ultra HD Expedition.
Like a celestial blanket the Milky Way forms an arc high above the antennas of the Atacama Large Millimeter/submilimeter Array. This arc is caused by the panoramic view of the image.
A panorama of ALMA at sunset. In the centre, the Moon can be seen. This image was taken during the ESO Ultra HD Expedition.
The Paranal platform photographed in January 2007. The four main Very Large Telescope (VLT) units can be seen, as well the four auxiliary telescopes.
什么东西又大又亮又美,仿佛披着云朵披风,而且正处于绕地球椭圆轨道上距离地球最近的点?当然就是近地点满月,这里捕捉到的影像拍摄于11月5日凌晨,地点是土耳其开塞利Kayseri,当时夜空正值月落前夕。发生在(或非常接近)近地点的满月,比普通满月略大略亮,因此也被称为“超级月亮”。事实上,这次近地点满月是2025年三次超级月亮中最接近和最明亮的一次。当太阳落下时升起,这次满月紧随着10月的丰收月,传统上也被一些人称为猎人月。

这片被称为海马星云的奇特星云,跨越数光年,在繁星点点和闪耀的氢气映衬下,呈现出迷人的轮廓。这片尘埃弥漫的暗星云位于北天的皇家星座-仙王座方向,是距离我们约1,200光年的银河系分子云的一部分。它也被列为巴纳德150号(B150),是天文学家E·E·巴纳德在20世纪初期编录的182个天空暗标记之一。低质量恒星群正在内部形成,但它们的塌缩核心仅在长红外波段下才能被观测到。尽管如此,仙王座中银河系深邃明亮的景象,依然为壮丽的银河景观增添了魅力。
北极光降临佛罗里达的夜空。事实上,在这张摄于11月11日佛罗里达州希尔德岛(Shired Island)的海天相接照片中,一颗耀眼的北金牛座流星划过繁星点点的夜空,照亮了海滩上方。每年这个时候,北金牛座流星雨的流星如期而至。然而,数位相机的曝光也记录下了极光的闪烁光芒,这种现象通常在地球较高纬度的地区才能看到。这些北极光,也称为极光,是近期大规模 极光活动的一部分,这些活动是由强烈的地磁风暴引起的。在过去的几天中,风暴性的太空天气是由多次冲击地球的日冕物质抛射和强烈的太阳活动所触发的。
