Fast radio bursts are millisecond-duration, extremely bright flashes of radio light that reach us from other galaxies. We do not know what they are but...
Dark matter, the “glue” that holds our Universe bound, remains a mystery. A key question to understand its nature is whether dark matter particles can interact...
The reason why the Vikings left Greenland in the early 15th century remains unclear. The declining temperature during the Little Ice Age had been thought to be...
Lessons from past warm periods in the Earth's history reveal that climate and atmospheric changes could lead to more intense seasonal rainfall, disturbing...
Analyzing seismic waveforms recorded by the InSight mission seismometer, we discovered and documented 47 marsquakes in the Cerberus Fossae region of Mars....
The gravity of massive objects can magnify background objects, making them appear larger and brighter. Precise alignment between a background star and a...
Better representation of Northern Hemisphere vegetation may resolve a scientific debate over how global temperatures changed during the past 12,000 years. Our...
Over the next 30 years, the expansion of cities will threaten global biodiversity unless we change the way that they are built. Greener cities can become part...
Disasters such as hurricanes, floods, and wildfires are increasing in frequency, and many locations are experiencing repeated disasters. Each disaster can...
We have discovered a new kind of repeating radio source using a sensitive low-frequency radio telescope in outback Western Australia. Its unusual properties...
The characteristics of an astronomical site limits the performance of telescopes. “Seeing”, the blurring of stellar images by atmospheric turbulence, is a key...
Volcanic hotspots like Hawaii are usually thought to be fed by hot blobs inside the Earth. A new class of cold hotspots is identified by inferring the...
