The arrival of 3I/ATLAS in our solar system spawned multiple proposals for a rendezvous mission to study it up close. As the third interstellar object (ISO) ever detected, the wealth of information ...

Researchers detail a 2035 Solar Oberth maneuver mission using chemical propulsion to intercept interstellar comet 3I/ATLAS within 35 to 50 years.

Earth's cosmic neighbourhood is more dynamic than imagined, hosting temporary 'mini-moons' captured by gravity and ...

Interstellar comet 3I/ATLAS reached a speed of 58 km/s upon arrival, and was too fast to be captured, making a short flyby a valuable high-value experiment in chemistry, dust physics, and solar ...

An international team of astronomers has discovered a distant planetary system that challenges long-standing theories of how ...

Out in the Kuiper Belt, the massive doughnut of debris beyond Neptune, about one in 10 kilometer-scale objects have surprised scientists with their unexpected shape. Rather than resembling a ball, ...

In a conventional system like our own, rocky planets such as Mercury, Venus, Earth, and Mars orbit closest to the host star. Farther out, gas giants ...

A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

Planetary systems in the Milky Way galaxy tend to follow a particular pattern: rocky planets toward the center, closest to ...

A 'ring of fire' eclipse is coming to Antarctica on Feb. 17.

Today (Feb. 17), an annular solar eclipse will commence its journey across a remote region of Antarctica where it will be visible to more penguins than people. The partial solar eclipse portion of the ...

Scientists may be one step closer in their hunt for signs of past life on Mars after the Curiosity rover's latest find.
