Star systems come in all shapes and sizes. Some have lots of planets, some have larger planets and others have no planets at all. But a particularly unusual system about 150 light-years from our own has scientists scratching their heads.
In 2016, astronomers discovered two planets orbiting the star HD 3167. They were thought to be super-Earths — between Earth and Neptune in size — and circled the star every one and 30 days. A third planet was found in the system in 2017, orbiting in about eight days.

Skywatchers taking in the view after sunset have a chance to see Venus and the moon line up with Jupiter and Saturn in the evening sky tonight (Nov. 8).
Look close to the southwestern horizon about 30 minutes after sunset and you'll be able to spot the waxing moon, just to the left of the bright glare of Venus . The moon and bright planet will appear to make a line with Jupiter and Saturn that stretches up and to the east.

Hunting for alien planets with a new solar telescope
Interstellar objects that accumulate like pebbles to form planets, study suggests | Daily Mail
Scientists are still unsure exactly how planets form, but interstellar objects may have played a role in constructing, a new study suggests.
Researchers at the Space Telescope Science Institute in Baltimore, Maryland believe that interstellar objects like 'Oumuamua or Comet 2I/Borisov may be considerably more prevalent in the universe.
Planetary evolution reveals a volatile history
To deepen our understanding of planet formation, scientists must find and observe the formation of many such systems. But watching a planet evolve in real time would take millions of years.
The most widely accepted model for planet formation, known as the nebular hypothesis, begins with a swirling disk of gas and dust—leftover material from the birth of a nearby star.

(CNN) I've always been a bit dazzled by the fact that, as humans, we truly are made of star stuff. This week, an element found in our teeth was detected for the first time in a galaxy 12 billion light-years away .
Watch Uranus and its brightest moons dance across space - CNET
The observatory tracked Uranus for four hours and made a video showing the planet's four brightest moons -- Titania, Oberon, Umbriel and Ariel -- moving around it. The celestial objects appear to slide across space as the stars in the background hold still. It's mesmerizing.
You might be sensing a theme to the moon-naming scheme for Uranus. Most of the moons are named for characters from William Shakespeare's plays. For fans of A Midsummer Night's Dream... yes, there is a moon named Puck, but it's too small to appear in the observatory's footage.
New 'Phase' Of Water Found Inside Planets Recreated On Earth By Scientists
According to scientists from the University of Chicago, the "strange black" ice can be found at the centre of planets like Neptune, Uranus, and even Earth .
The study was published in Nature Physics, whereby scientists explained how such ice could be created in extreme conditions. To recreate the extreme conditions required to hold water in this state on Earth, scientists pressed water between two diamonds (considered the hardest material on Earth) .
