Since the third Gaia data release in 2022, wide binary stars with separation greater than several thousand astronomical units have been intensely investigated across the world, to probe the nature of ...

Out in the Kuiper Belt, the massive doughnut of debris beyond Neptune, about one in 10 kilometer-scale objects have surprised scientists with their unexpected shape. Rather than resembling a ball, ...

The simulations showed that the gravity hole was initially much less pronounced. Between roughly 50 million and 30 million years ago, however, it intensified significantly. This period coincides with ...

A peer-reviewed study modeling Mars transit times for chemical propulsion rockets found that even optimized Starship-class trajectories would still require roughly three months to reach the Red Planet ...

A new study led by the University of Florida has revealed that one of the planet’s most significant "gravity holes" sits directly beneath Antarctica.

They show up as a mathematical solution in general relativity, basically as a time-reversed version of a black hole. Some ...

SIGNS of an alien planet that’s about the same size as Earth have been picked by up a Nasa telescope. Scientists say it might ...

Scientists using Juno report Jupiter is smaller than previously thought, enhancing understanding of its shape, interior density, gravitational field, and comparison to other gas giant planets ...

For nearly a century, astronomers have watched galaxies spin and the universe expand in ways that visible matter alone cannot explain. The dominant answer has been dark matter, an unseen substance ...

Planet Labs barreled into December on a high note -- almost literally. On the last business day of the previous month, Planet Labs announced the successful launch of a pair of artificial intelligence ...

Astronomers have found what appears to be one of the strangest known worlds in the universe. It orbits a type of rapidly spinning neutron star called a pulsar – this in itself is unusual, but it is ...
