NASA’s Hubble Space Telescope has discovered 16 extrasolar planet candidates orbiting a variety of distant stars in the central region of our Milky Way galaxy. The planet bonanza was uncovered during ...

Not every planet has a sun. Scattered across the Milky Way are worlds that belong to no star at all, drifting through ...

Erik Gillis, a PhD student in McMaster University’s Department of Physics and Astronomy, is lead author of a new study revealing that the most common planets in our galaxy don't exist around the most ...

The distribution of HI hydrogen in the Whirlpool Galaxy (M51) as determined by the THINGS VLA survey extends far beyond the visible stars in the galaxy and its satellite NGC 5195 (marked by cross), ...

– January 7, 2026 (London time) – One of the biggest recent surprises in astronomy is the discovery that most stars like the Sun harbor a planet between the size of Earth and Neptune within the orbit ...

The Euclid space telescope unveiled seven more rogue planets in an image of the Horesehead Nebula, roughly 1,500 light years from Earth. Making the find even more incredible is that these ...

What can the galactic habitable zone (GHZ), galactic regions where complex life is hypothesized to be able to evolve, teach scientists about finding the correct stars that could have habitable planets ...

Over the past decade or so, astronomers have speculated about the characteristics of rogue planets in the Milky Way galaxy. These "free-floating" worlds don't orbit stars, but instead roam the ...

Astronomers now estimate there is at least one planet for every star in our galaxy. These worlds, called exoplanets, are planets that orbit stars outside our solar system. But new research from ...

(CNN) – Astronomers have discovered a rare family of six planets about 100 light years from Earth. The exo-planets are larger than the Earth but smaller than Neptune. The planets are in a ...

Scientists now have direct evidence that a planet — not just failed stars — can rove the galaxy after a violent expulsion from its orbit. Credit: NASA / JPL-Caltech / R. Hurt illustration Astronomers ...
