A basin region within Margaritifer Terra on Mars contains deposits of clay-bearing sediment that provide evidence of flowing water on the red planet as recently as 2.5 billion years ago.
An analysis of the craters on Bennu’s surface provides evidence that the rubble pile asteroid is protected from smaller impacts by the boulders scattered on the surface
Using data from the fabulous Gaia mission, researchers have detected four new brown dwarfs as well as several other unusual companions to 25 stars in the Milky Way.
Using the radiation signatures of quasars, scientists have determined when the era of reionization ended in our universe – about 1.1 billion years after the Big Bang.
Astronomers combined observations of far distant galaxies exhibiting no signs of star formation and found active supermassive black holes that may have contributed to the evolution of their parent galaxies. Plus, rocket launches, detecting earthquakes, and why Uranus and Neptune are different shades of blue.
Fast, strong magnetic winds caused by quickly rotating pulsars may be accelerating particles like electrons to extremely high-energy states and creating gamma-ray photons in their wake.
Researchers using radioactive decay analysis have recreated the early history of some asteroids in our solar system, revealing a more chaotic phase than previously thought
A forensic analysis of the element concentration found in the Hypatia stone finds evidence in the cometary fragment, which may have impacted Earth 28 million years ago, of a supernova origin story
The flash of a pulsar about 3,000 light-years from our solar system was caused by a ‘black widow’ binary consuming a smaller star. Intriguingly, a third companion star is orbiting the pair, which may have originated near the Milky Way’s center.
A new paper looks at marsquakes and what is causing them, which turns out to be magma moving. And Curiosity has found rocks it needs to go around. Then there is the weather on Mars
