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
Teflon objects (orange cylinders) were placed in a waveguide with a rectangular cross section. Then, an electromagnetic signal (blue wavefront) was injected from the right to extract information about the metallic cuboid shown in gray. By measuring the wave field in the area shown in red, researchers can show how information is generated and transported
A rare burst of light from a dead star is likely to be visible to humans in earth this summer in a fleeting but potentially gloomy celestial display that scientists are calling “a once-in-a-lifetime event.” The technical term for the impending cosmic explosion is nova, which occurs when a white dwarf suddenly and often spectacularly
Following one dirty anchorage on the International Space Station last week, Boeing managed to send a pair of NASA astronauts to the orbiting laboratory. The stressful Starliner saga continues as the crew capsule developed more leaks in its service module. NASA is currently evaluating its ability to return the pair to Earth. The first Sonos
