Earlier estimates of its age were around 7 billion years, but a new study suggests it’s much older.

The Solar System is a weird place filled with incredible physics and geological oddities that often break down in human terms ...

What is the actual speed and direction of our solar system as it moves through the cosmos, and how does this compare to longstanding cosmology models? This is what a recent study published in Physical ...

The comet formed in a cold and distant part of the early Milky Way up to 12 billion years ago, putting it just under 2 ...

An object eight times the mass of Jupiter may have swooped around the sun, coming superclose to Mars' present-day orbit before shoving four of the solar system's planets onto a different course. When ...

Our solar system is way more bizarre and dynamic than what our school textbooks taught us. From Venus being super hot to ...

When I was a kid, there were nine planets. Now we know of thousands! But that includes exoplanets, alien worlds that orbit alien suns. Only eight planets call our solar system home. Or there might ...

Black holes about the size of a hydrogen atom could be careening through the solar system unnoticed. But their days of stealth may be numbered. Two teams of researchers propose methods to search for ...

Estimating ages of specific events is one of the most difficult problems in astrophysics. While we have a precise (and probably accurate) age for the solar system, we do not have precise ages for each ...

Oh, we humans do love a cleanly defined boundary, don’t we? They make things easier, after all. If we’re trying to categorize something, knowing what labeled bin to put it in is handy. If we’re ...
