©Caltech / R. 伤害(IPAC) “星球九号”的艺术家插图,一个比地球大10倍的假想世界。第九行星的证据继续增加,但科学家们尚未发现它的原因可能还有很多 - 它可能正在隐藏。

2017年10月,美国国家航空航天局发表声明称,九号行星距太阳的距离可能比海王星高20倍,甚至可以说“现在很难想象我们的太阳系没有一颗行星九而不是一颗行星”。

但它可能尚未被发现的原因是由于相同的距离。在那个距离,相当于600个天文单位(1 AU定义为地球和太阳之间的距离,或大约9300万英里),它将比海王星暗160,000倍。宾夕法尼亚州立大学的天文学家凯文卢赫曼告诉华盛顿邮报,在1000澳元,这是一个“砖墙,基本上”,使任何潜在的星球几乎不可能使用现有技术。

然而,科学家认为,确实存在另一个行星的可能性,这个行星可能具有“地球质量的10倍”。

Slide 49 of 75
Slide 50 of 75: The Calabash Nebula, also known as the Rotten Egg Nebula, pictured here is a spectacular example of the death of a low-mass star like the sun. The star is seen going through a rapid transformation from a red giant to a planetary nebula, blowing its outer layers of gas and dust out into the surrounding space. Astronomers rarely capture a star in this phase of its evolution because it occurs within the blink of an eye — in astronomical terms.
Slide 51 of 75: This colorful bubble is a planetary nebula called NGC 6818, also known as the Little Gem Nebula. It is located roughly 6,000 light-years away in the constellation of Sagittarius.
Slide 52 of 75: This image captures the cosmic pairing of the star Hen 2-427, commonly known as WR 124, and the nebula M1-67 which surrounds it. Both objects are found in the constellation of Sagittarius and lie 15,000 light-years away. The nebula is estimated to be no more than 10,000 years old — just a baby in astronomical terms.
Slide 53 of 75: This picture of young stars flaring to life was released by NASA to commemorate a quarter century of solar system exploration by Hubble Space Telescope. Scientists aimed Hubble’s near-infrared Wide Field Camera 3 through a dusty veil covering the stellar nursery to capture the nebula and the dense concentration of stars in the central cluster. The star cluster is about 2 million years old and contains some of our galaxy’s hottest, brightest and most massive stars.
Slide 54 of 75: This shot shows a maelstrom of glowing gas and dark dust within one of the Milky Way’s satellite galaxies, the Large Magellanic Cloud (LMC). At the heart of this cosmic cloud lies the butterfly-shaped Papillon Nebula, which is thought to be tightly linked to the early stages of massive star formation.
Slide 55 of 75: Dubbed a colorful holiday ornament in space, NGC 6326 is a planetary nebula with glowing wisps of outpouring gas that are lit up by a central star nearing the end of its life. This picture was taken using the Hubble Space Telescope’s Wide Field Planetary Camera 2.
Slide 56 of 75: This image shows the demise of a star like the sun. The star is ending its life by casting off its outer layers of gas, which formed a cocoon around the star
Slide 57 of 75: This image shows a spiral galaxy known as NGC 7331, located about 45 million light-years away. Facing us partially edge-on, the galaxy showcases its beautiful arms, which swirl like a whirlpool around its bright central region.
Slide 58 of 75: IC 342, one of the brightest in the sky, is nicknamed the “Hidden Galaxy” because of its obscure position next to the equator of the Milky Way’s galactic disk, which is thick with glowing cosmic gas, bright stars and dust. The galaxy, however, is active, as indicated by the range of colors seen in the image.
Slide 59 of 75: The spiral galaxy NGC 3521 has a soft, woolly appearance as it is a member of a class of galaxies known as flocculent spirals. Fluffy patches of stars and dust show up here and there throughout the disks in flocculent spirals. NGC 3521 is located almost 40 million light-years away in the constellation of Leo.
Slide 60 of 75: Lying about 500 million light-years away in the constellation of Sculptor, the cartwheel shape of this galaxy is the result of a violent galactic collision.
Slide 61 of 75: This image shows the center of the Lagoon Nebula in the constellation of Sagittarius. The region is filled with intense winds from hot stars, churning funnels of gas, and energetic star formation, all embedded within an intricate haze of gas and pitch-dark dust.
Slide 62 of 75: Large Magellanic Cloud is home to one of the largest and most intense regions of active star formation known to exist anywhere in our galactic neighborhood — the Tarantula Nebula. This image shows both the spindly, spidery filaments of gas that inspired the region’s name, and the intriguing structure of stacked “bubbles” that forms the Honeycomb Nebula (to the lower left).
Slide 63 of 75: Shown in this image is a small section of the expanding remains of a massive star, Veil Nebula, that exploded about 8,000 years ago. The debris is one of the best-known supernova remnants and derives its name from its delicate, draped filamentary structures. This close-up look unveils wisps of gas, which are all that remain of what was once a star 20 times more massive than the sun.
Slide 64 of 75: The two-lobed Red Spider Nebula harbors one of the hottest stars known and its winds generate waves that are 62.4 billion miles high. The atoms caught in the supersonic shocks caused by the waves emit the radiation seen in the picture.
Slide 65 of 75: An underlying population of infant stars embedded in the nebula NGC 346 are seen forming from gravitationally collapsing gas clouds.
Slide 66 of 75: Roughly 50 million light-years away lies a somewhat overlooked little galaxy named NGC 1559. Pictured here by Hubble’s Wide Field Camera 3, this barred spiral lies in the little-observed southern constellation of Reticulum (the Reticule).
Slide 67 of 75: This Hubble image shows the supernova remnant SNR 0509-68.7, also known as N103B. It is located 160,000 light-years from Earth in the neighboring galaxy of Large Magellanic Cloud. The actual supernova remnant is the irregular shaped dust cloud, at the upper center of the image. The gas in the lower half of the image and the dense concentration of stars in the lower left are the outskirts of the star cluster NGC 1850.

在过去的25年里,哈勃太空望远镜一直是人类对不断扩张的宇宙的注视。望远镜一直负责捕捉有史以来最令人惊叹的宇宙图像。

加入我们,我们将观看宇宙的恒星挂毯,其中包含来自地球轨道天文台的一些标志性图像。

图为:蝴蝶从行星状星云NGC 6302中的恒星灭亡中浮现出来。类似于生物精致的翅膀实际上是在燃烧加热到超过36,000华氏度的燃气的大锅。天然气以超过600,000英里/小时的速度穿越太空,速度足以在24分钟内从地球到月球!

东京大学卡夫利物理与数学研究所副教授Surhud More告诉Advocator说:“每次我们拍照时,都有可能行星九存在于镜头中。”

Slashgear报告说,在发现这颗行星之前可能需要长达1000年的时间。

来自加州理工学院的迈克尔·布朗曾表示,他认为最终将会发现“九号星球”,但它将需要比目前更强大的望远镜和行星发现技术。

在2017年10月的声明中,与布朗合作的加州理工学院行星天体物理学家康斯坦丁·巴蒂金说,有五种不同的观测证据可以指出这个星球的存在。

五行证据是:

柯伊伯带中的六个已知物体,所有物体都具有指向相同方向的椭圆轨道。

物体的轨道都以相同的方式倾斜; 30度“向下”。

计算机模拟显示有更多物体“相对于太阳平面倾斜”。

行星九可能是我们太阳系中行星倾斜的原因; 与太阳的赤道相比,行星轨道的平面倾斜约6度

来自柯伊伯带的一些物体在与太阳系中其他物体相反的方向上运行。

“没有其他模型可以解释这些高倾角轨道的怪异,”Batygin补充道。“事实证明,第九行星为他们这一代人提供了一条自然的途径。这些东西在第九行星的帮助下被扭曲出太阳系飞机,然后由海王星向内散射。”
