Caption: 這幅圖像由兩張照片合成，顯示了系外行星老人增四b和一個物質盤，它們都圍繞年輕恆星老人增四運行。這兩張照片都是在紅外波段拍攝的。圍繞太陽之外的恆星運行的行星稱為“系外行星”，內側圖像即為首批被拍攝到的系外行星照片之一。這張照片是利用一種叫做“自適應光學”的技術拍攝的，該技術可以消除地球大氣引起的模糊效應，從而使星光不再散開。然後，星光被高度集中，並由一個叫做“星冕儀”的遮擋圈（此處顯示為黑圈）遮擋，其周圍的波紋是成像過程中的偽影。老人增四b是一顆氣態巨行星，質量約為木星的12倍，在黑圈左上方顯示為一個小點。 外側圖像顯示的是年輕恆星老人增四周圍溫暖物質盤的熱輻射。我們的視線處於這個物質盤的側面，因此它顯示為一條線。這個由氣體和塵埃組成的物質盤提供了形成老人增四b的物質。

Caption: 這組圖像展示了太陽系外行星（系外行星）β Pictoris b 的軌道運動。這顆行星是每幅圖中的亮點。行星的主星被隱藏在每幅圖中間的黑圈後面。這樣做是為了去掉更亮的主星，否則主星的光會掩蓋行星的光。行星軌道側面對著我們。從這個角度觀察軌道，會讓人覺得行星是沿著一條直線運動的。 2015年2月至2016年11月期間，β Pictoris b似乎越來越靠近它的主星。之後，這顆行星離恆星如此之近，以至於近兩年都沒有人看到它，之後它又再次出現在恆星的另一側。

Caption: The constellation Pictor with its bright stars and surrounding constellations. Pictor is surrounded by (going clockwise from the top): Columba, Caelum, Dorado, Volans, Carina and Puppis. Pictor is notable for its second brightest star, Beta Pictoris. This young star hosts a large disk of dusty material left over from the planet formation process along with two planets, one of which Beta Pictoris b was one of the first planets to be directly imaged by astronomers. Pictor is a southern constellation and thus the whole constellation is visible at some point in the year throughout the southern hemisphere. The whole constellation is also visible from some equatorial regions of the northern hemisphere with parts of the constellation visible to the remaining northern equatorial regions and some northern hemisphere temperate zones. Pictor is best viewed in the northern hemisphere winter and southern hemisphere summer. The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly. The dotted boundary lines mark the IAU's boundaries of the constellations and the solid green lines mark one of the common forms used to represent the figures of the constellations. Neither the constellation boundaries, nor the lines joining the stars appear on the sky.
