New photos of the recently discovered asteroid 2024 MK, which zoomed past Earth in late June, reveal that the massive space ...

Using gravitational microlensing, scientists have discovered a rare, large planet at the edge of the Milky Way. The planet is ...

Stars often whip their planets with solar winds and radiation, pull them ever closer with gravity and sear them with heat.

This discovery marks the first known case of a compact planetary system with such a noticeable tilt between close planet ...

The discovery of the exoplanet, a super-Earth called Kepler-735c, is all down to something called transit timing variations, ...

Gravitational assists are an emblematic example of why space travel is hard —it is exactly rocket science, after all. Gravity ...

On their way to a colony planet around Proxima Centauri b, roughly 4.2 light years from Earth, the crew of the Ark One suffers a species-threatening catastrophe while still a year away from their ...

The conclusion that most rogue worlds are small makes more sense than the idea that they are Jupiter-size, Dr. Bennett said. That’s because planets are thought to go rogue when two protoplanets ...

Thanks to the map, the researchers found about 20 of these weird massive structures, which varied in size, but were about 300-400 kg/m 3 more dense than the surrounding rock.

Temperature: The average temperature at the top of clouds on Jupiter is –244° F (–153° C). Escape velocity: To escape Jupiter’s gravity, you have to travel 133,100 miles (214,200 km) per ...
