Fresh off the excitement of the Perseids meteor shower is a chance to see six planets lined up in the sky at once. These events, colloquially known as planet parades, occur occasionally with the most ...

Space is a very big place, and as such, it's full of mysteries that scientists can't explain. Some of this is simply because it's impossible to fully observe, thanks to its sheer size and the ...

Most planet-forming disks have warps that can lead to planets on inclined orbits, which could explain where the tilt of Earth's orbit came from. The origin of the differing tilts in the orbits of the ...

Somewhere at the edge of the solar system a new Earth-sized world might be lurking, dubbed Planet Y. Astronomers have long proposed that there might be hidden planets beyond the Kuiper belt, a region ...

If you look up on a clear night, the brightest and largest object in the sky will probably be the moon. And unless you have a decent telescope, it is the only natural satellite you can see with your ...

The latest research on asteroid Bennu has revealed its heterogeneous origin and a parent world with flowing water, adding to the evidence that this small and somewhat dangerous rock is extremely ...

The U.S. planetary science community is sounding the alarm about plans to discard a nuclear technology that has powered dozens of NASA missions over the past 50 years But RPS is expensive, costing ...

The textbook picture of how planets form—serene, flat disks of cosmic dust—has just received a significant cosmic twist. New research, published in Astrophysical Journal Letters, is set to reshape ...

"Considering the direction and frequency of our most common signals gives insights into where we should be looking to improve our chances of detecting alien technosignatures." Scientists have taken a ...

Scientists all over the world have been poring over samples of Bennu ever since material from the asteroid was brought to Earth in 2023, courtesy of NASA 's OSIRIS-REx mission, which flew alongside ...
