The NSF-DOE Vera C. Rubin Observatory in Chile recently captured rare footage of the visitor known as 3I/ATLAS — only the ...

Professional analysis of the Voyager probes’ journey toward the Oort Cloud, examining the likelihood of collisions and ...

The existence of the Oort Cloud was first proposed in 1950 by Dutch astronomer Jan Oort, who imagined it as a shell of icy bodies swirling around the sun from up to 1.5 light-years away.

The Oort cloud, if it indeed exists, likely isn’t unique to our own solar system. Correa Otto says that some astronomers believe these clouds exist around many solar systems.

An accidental discovery might change how we think about one of the most mysterious structures in our solar system. The Oort Cloud, a large expanse of icy bodies revolving around the sun at a distance ...

The Oort cloud could stretch as far as a lightyear away from our sun. Like the name suggests, the Oort cloud is kind of cloudy, and surrounds our solar system like a wide but tenuous shell.

We don’t know very much about the Oort cloud, except from hypotheses based on physics. We need to actually see some of those icy bodies—Oort Cloud Objects, or OCOs if you like—so that we can ...

While the dwarf planet is incredibly far out, it’s still not far enough to be part of the Oort cloud, a hypothesized cloud of icy debris that surrounds the solar system’s disc in a spherical ...

New Oort Cloud comets are discovered all the time, a dozen or so per year in recent years. The odds of any of them colliding with Earth are extremely low. But it is possible.
