Neptune’s far-flung moon Nereid may be the last of the planet’s original companions that managed to survive a cosmic crash, scientists reported Wednesday.

A team of scientists has recorded one of the most detailed views ever of a failed solar eruption, a powerful blast from the sun that never broke free. Their work is published in the journal Nature Astronomy.

LSU researchers helped uncover what may be the first clear detection of gamma rays from a superluminous supernova, using data from NASA’s Fermi Gamma-ray Space Telescope—a breakthrough that offers new insight into the powerful magnetars believed to drive some of the universe’s brightest stellar explosions.

On a special night, if you are lucky, you might catch a faint red glow quietly lighting up Japan’s sky, stretching low along the horizon and easy to miss if you are not looking carefully. Subtle and diffuse, it probably appears as a soft crimson haze. But behind this glowing beauty are countless charged particles traveling from the sun toward Earth’s magnetic field, which then collide with oxygen atoms high above our planet. At these great heights, where the air is extremely thin, the excited oxygen atoms then release their energy as dim red light, creating the auroras we see from the ground.

As orbital data centers move from concept to reality, scalable power generation and efficient thermal management are emerging as critical enabling technologies. A new whitepaper from Redwire examines how power generation and distribution, along with […]
