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 ...

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 ...

Scientists observe a dramatic collision between two planets, offering insights into the formation of Earth's Moon 4.5 billion years ago.

Over 4 billion years ago, as planets were coalescing around the newborn Sun, our star may have gone on an epic road trip across the Milky Way along with thousands of stellar "twins." And we may owe ...

Astronomers using NASA’s James Webb Space Telescope have produced the first three-dimensional map of Uranus’ ionosphere, ...

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 ...

It provides a dynamic, time-resolved view of planetary transformation, a missing link between young inflated worlds and the compact sub-Neptunes that populate the galaxy.

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), ...

Scientists uncover a new reason for fewer planets around twin stars. Einstein's theory of general relativity shows that close ...

At the end of 2021 humanity launched into a distant orbit the most technologically advanced (and expensive) space telescope ever made. Now parked at the second Sun-Earth Lagrange point (L2) in the ...

– 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 ...
