NASA and its commercial partners are conducting demonstrations of advanced satellite relay capabilities supporting near-Earth science missions as part of the Communications Services Project.

Cosmic “touchdown airbursts” — explosions of comets or asteroids above Earth’s surface — may be far more common and destructive than previously thought, according to new research. Unlike crater-forming impacts,

Today, oceans cover about 70% of Earth’s surface. This stark contrast has long driven scientific interest in how water managed to survive Earth’s transition from an early molten state to a largely solid planet, and how it was preserved rather than completely lost during this violent period.

One key component might be RNA, a molecular cousin of DNA found in every form of life on Earth, and now scientists say they have shown how it could have formed on our planet eons ago. But not everyone is convinced,

Rising global emissions of hydrogen over the past three decades have added to the planet's warming temperatures and amplified the impact of methane, one of the most potent greenhouse gases, according to new research published in Nature.

New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through a solid iron lattice. This unusual behavior makes the core soft, matching seismic observations that have puzzled scientists for decades.

The new dataset, published in Earth System Science Data by 16 scientists, shows a significantly cooler Earth from the late 1700s through 1849 compared with 1850-1900 — the latter being what scientists have defined as the “preindustrial” baseline period used to assess the planet’s temperature change.

When the early Earth’s magma ocean crystallized 4.4 billion years ago, the deep mantle trapped an ocean’s worth of water, scientists say.

Rocky planets like our Earth may be far more common than previously thought, according to new research published in the journal Science Advances. It suggests that when our solar system formed, a nearby supernova (the massive explosion of a star near the end of its life) bathed it in cosmic rays containing the radioactive ingredients to make rocky,

Human activities increasingly lead to climate change, overuse of water, hazards and the destruction of biodiversity — to name just a few. Earth scientists need to take on the challenge of serving society on these issues, in close collaboration with ...
