A team of astronomers from the University of Montreal has discovered a new potentially habitable exoplanet orbiting the red dwarf star L 98-59, 35 light-years from Earth. This discovery means there ...

Analysis reveals what appears to be a channel of hot, low-density plasma stretching out from our solar system toward distant ...

A group of astronomers from the US, Europe, Chile and South Africa have determined that 70,000 years ago a recently discovered dim star is likely to have passed through the solar system’s distant ...

Long before humans walked the Earth, your solar system had a brush with two blazing blue stars that passed surprisingly close by. Nearly 4.4 million years ago, they swept past at a distance of only ...

Nearly 4.5 million years ago, two enormous, blazing stars swung close to the solar system. They did not touch the sun, but they came close enough to leave a permanent mark on the thin mist of gas that ...

Microscopic crystals extracted from meteorites could help settle a debate about the birth of our patch of the Milky Way.

Astronomers studying a disk of material circling a still-forming star inside our Galaxy have found a tantalizing result — the inner part of the disk is orbiting the protostar in the opposite direction ...

Our solar system might still bear the scars from an extremely close shave with an alien star. Such an encounter – the closest pass we know of – would have shaken up objects on the outskirts and might ...

For centuries, astronomers have sought to understand the formation and evolution of the solar system and the dynamics that govern it. In particular, there is the long-standing question of whether or ...

Our solar system passed through a vast wave of gas and dust around 14 million years ago, dimming Earth’s view of the night sky. The wave may even have left traces in our planet’s geological record.
