Methane is a powerful greenhouse gas with strong heat-trapping capabilities. Although there is less methane in the atmosphere than carbon dioxide, the foremost greenhouse gas, researchers attribute 30 ...

NASA’s Kepler Space Telescope is no longer operating, but its data still has surprises. Astronomers re-checking observations from Kepler’s extended K2 mission have identified what looks like a small ...

Climate change makes nitrous oxide disappear faster, creating new uncertainty for future climate and ozone predictions.

The planet's radius from pole to center has been revised to 66,842 km, and at the equator to 71,488 km. That makes it about 12 km smaller along the poles, and about 4 km smaller at the equator, than ...

On Mars or the Moon, researchers use high-resolution optical cameras to spot “skylights,” which are essentially holes in the ground where a cave roof has collapsed. But on Venus, the thick atmosphere ...

A planet that looks faintly familiar has emerged from old space telescope data, though it may be far from welcoming. Scientists analysing observations.

A common iron mineral hiding in soil turns out to be far better at trapping carbon than scientists realized. Its surface ...

NASA confirmed that the rockets would deploy four subpayloads to collect data on electron flow and plasma density.

Earth’s magnetic field and atmospheric oxygen appear to have moved in sync for half a billion years, pointing to a surprising connection between the planet’s deep interior and life-supporting ...

Auroras, shimmering bands of light that shoot through the night sky near the Earth’s poles, can follow patterns known as arcs ...

NASA has selected two Earth science missions for development, one focused on studying the atmosphere and the other on terrestrial ecosystems and ice.

A new study reveals that chemicals used to replace ozone-damaging CFCs are now driving a surge in a persistent “forever ...
