A trio of stories examines the possibilities for finding life in strange, new places, including deep underground here on Earth, in the subsurface oceans of Europa, and fossilized within sedimentary rocks on Mars.
A star cataloged as Gliese 781 is approaching our solar system and in slightly more than a million years from now, will reach the Oort Cloud, likely disrupting the orbits of icy bodies that could head toward Earth
Starting with the stunning release of JWST’s first image of galaxy cluster SMACS 0723 on July 11, the bonanza continued the morning of July 12 with newly released images of Stephan’s Quintet, the Carina Nebula, the Southern Ring Nebula, and exoplanet WASP-96b
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
