Humanity has lost an interstellar pioneer. Ed Stone, who served as project scientist for NASA’s groundbreaking Voyager mission from 1972 to 2022, died on Sunday (June 9) at the age of 88. “Ed Stone was a pioneer who dared great things in space. He was a dear friend to all who knew him and a

A new study published in Nature Physics presents a theory of electron-phonon coupling that is influenced by the quantum geometry of electronic wave functions. The movement of electrons in a lattice and their interactions with lattice vibrations
Summary: Mental maps in the brain are activated when we think about sequences of experiences, even without physical movement. In an animal study, they found that the entorhinal cortex contains a cognitive map of experiences, which is activated during mental simulation. This is the first study to show the cellular basis of mental simulation in

The consequences of a thermonuclear explosion in a binary star system about 3,400 light years away has been witnessed by Hubble Space Telescope. HM Sagittae, or HM Sge for short, is what is known as a symbiotic system, in which a white dwarf is eating with a friend red giant star The stolen material forms
While standing on planet Earth, it’s easy to forget that we’re sitting on a rock hurtling through the Solar System on a path that might collide with other (smaller) space rocks, mostly because we can’t feel that motion. If you ever feel like putting yourself completely at the mercy of random space rocks, we recommend
Every fall, a narrow pass in the Pyrenees mountain range between southern France and northeastern Spain is flooded with a torrential stream of marmalade butterflies, pollinators with citrus-colored bodies and black stripes. The hoverflies avoid harsh mountain winds by flying close to the ground, making the sunlit streams look “almost like a river of golden
Astronomers expect a “new star” to appear in the night sky anytime between now and September in a celestial event that has been years in the making, according to NASA. “It’s a once-in-a-lifetime event that will create a lot of young astronomers out there, giving young people a cosmic event they can observe for themselves,
Space changes you, even during short trips off-planet. Four people who spent three days outside Earth in September 2021 experienced physical and mental changes that included modest declines in cognitive tests, heightened immune systems and genetic changes within their cells, scientists report in a suite of papers published Tuesday in the journal Nature and some.
HUSTON – Hello, from your fellow Houstonian! I know it’s already hot in Texas as we prepare for the intense summer and humid heat we are blessed with every year. Apparently it’s getting hotter as we get older — or is it just me? Anyway, I wasn’t much of a beach girl growing up, but
