Astronomers have spotted tantalizing signs of a planet in a star system outside the Milky Way, which, if it's confirmed, would be the first ever found in another galaxy.
The discovery, reported in a study published Monday in the journal Nature Astronomy, demonstrates a new technique for finding far-off worlds, and it could significantly expand the search for so-called extragalactic exoplanets.
Scientists find strange black 'superionic ice' that could exist inside other planets
This type of ice forms at extremely high temperatures and pressures, such as those deep inside planets like Neptune and Uranus.
"It was a surprise—everyone thought this phase wouldn't appear until you are at much higher pressures than where we first find it," said study co-author Vitali Prakapenka, a University of Chicago research professor and beamline scientist at the Advanced Photon Source (APS), a U.S.

We argue that taxonomical concept development is vital for planetary science as in all branches of science, but its importance has been obscured by unique historical developments.
The literature shows that the concept of planet developed by scientists during the Copernican Revolution was theory-laden and pragmatic for science. It included both primaries and satellites as planets due to their common intrinsic, geological characteristics.
The 6 spookiest planets of the cosmos
From vicious black holes that swallow up everything around them to undetectable dark matter that pushes the boundaries of the expanding universe , the silent void of space is as spooky as it is mysterious.
But perhaps nothing is more terrifying than the thought of ending up on a fiery world with raging volcanoes, iron rain, or hellish temperatures. These horrifying planets are perhaps the last place you want to be, especially if you're alone.

HONOLULU (HawaiiNewsNow) - Scientists led by a team at the University of Hawaii at Manoa have discovered one of the youngest planets ever observed around a distant infant star.
Its discovery is unique, researchers said, because it is newly formed and can be directly observed.
How to Find Hidden Oceans on Mysterious Worlds?
A new study shows how the chemicals in an exoplanet’s atmosphere can, in some cases, reveal whether or not the temperature on its surface is too hot for liquid water In our solar system, planets are either small and rocky (like Earth) or large and gaseous (like Neptune).
In the new study , accepted in the Astrophysical Journal Letters, researchers show how the chemistry of those atmospheres could reveal clues about what lies beneath – specifically, which planets are too hot to support liquid-water oceans.
Scientists believe they've spotted the first planet outside the Milky Way - CBS
NASA says a group of scientists may have discovered signs of a new planet beyond the Milky Way. The potential discovery could be the first-ever planet found in another galaxy.
The potential planet, which is unnamed and roughly the size of Saturn, was spotted in the spiral galaxy Messier 51, or what's known as the Whirlpool Galaxy, about 28 million lightyears away from the Earth, according to NASA.
Look up to see the Kootenay sky full of planets – Nelson Star
Over time, constellations were formed by connecting the brighter points of light of a certain area of sky.
Here, imaginary shapes were formed representing an object, person, animal or even a god – the constellations. Then came the mythologic stories and how they interacted in the celestial theatre.
Pluto is no longer a planet — or is it? | Science News for Students
For 76 years, Pluto was the beloved ninth planet. No one cared that it was the runt of the solar system, with a moon half its size. No one minded that it had a tilted, oval-shaped orbit. Pluto was a weirdo, but it was our weirdo.
"Children identify with its smallness," wrote science writer Dava Sobel in her 2005 book The Planets . "Adults relate to its … existence as a misfit." People felt protective of Pluto.
