Satellite data reveal nearly 20,000 previously unknown deep-sea mountains
By looking for tiny bumps in sea level caused by the gravity of subsurface mountains, researchers have roughly doubled the number of known seamounts.
- Environment
Satellite imagery reveals ‘hidden’ tornado tracks
Twisters that churn over barren landscapes leave scars that are invisible to human eyes but are detectable with infrared light.
- Agriculture
Dry farming could help agriculture in the western U.S. amid climate change
Some farmers in the western United States are forgoing irrigation, which can save on water and produce more flavorful fruits and vegetables.
- Planetary Science
Marsquakes hint that the planet might be volcanically active after all
Seismic data recorded by NASA’s InSight lander suggest molten rock moves tens of kilometers below the planet’s fractured Cerberus Fossae region.
- Earth
Landslides shaped a hidden landscape within Yellowstone
Scientists have used lasers to get a detailed view of the national park’s topography, and they’ve spotted more than a thousand landslides.
- Planetary Science
Mars’ buried ‘lake’ might just be layers of ice and rock
Evidence grows that possible detections of liquid water buried near Mars’ south pole might not hold water.
- Environment
Mangrove forests expand and contract with a lunar cycle
The carbon-sequestering trees grow in a roughly 18-year cycle according to tides influenced by the moon’s orbit, a study in Australia finds.
- Planetary Science
Passing through the Milky Way’s arms may have helped form Earth’s solid ground
Barrages of comets stirred up by the early solar system’s journey around the center of the galaxy could explain the timing of ancient rock formation.
- Astronomy
The discovery of the Kuiper Belt revamped our view of the solar system
Thirty years ago, astronomers found the Kuiper Belt, a region of space home to Pluto and other icy worlds that helped show how the solar system evolved.
- Planetary Science
Asteroid impacts might have created some of Mars’ sand
Roughly a quarter of the Red Planet’s sand is spherical bits of glass forged in violent impacts, new observations reveal.
- Astronomy
A celestial loner might be the first known rogue black hole
The object could be the first isolated stellar-mass black hole identified in the Milky Way — or it might be an unusually heavy neutron star.
- Planetary Science
NASA’s InSight lander has recorded the largest Marsquake yet
The magnitude 5 temblor, detected May 4, will help scientists learn more about the Red Planet’s interior.
