Astronomers have discovered the very first confirmed planetary system that resembles the expected fate of our solar system.

Two NAU astronomers presented groundbreaking research at the annual meeting of the Division for Planetary Sciences, a branch of the AAS.

A team of space scientists has published a paper suggesting that there may be an Earth- or Mars-sized planet orbiting beyond Neptune.

So far, we know of only two interstellar objects (ISO) to visit our solar system. They are 'Oumuamua and 2I/Borisov. There should be more.

In addition to gathering data on hundreds of known objects, this survey revealed 461 previously undetected objects.

The huge comet or minor planet, which astronomers are calling 'the coolest thing we've found', is expected to reach Saturn in 2031

The rise and fall of sunlight reflected off the Moon, as it presents its different faces to us, is known as a "phase curve"

The familiar star at the center of our solar system has had billions of years to mature and ultimately provide life-giving energy to us here

The asteroid credited with the extinction of the dinosaurs 66 million years ago likely originated from the outer half of the solar system

Scientists think there may be 100 trillion Borisov-like interstellar comets, meteors, asteroids and other debris in the Oort cloud
