NASA’s InSight Mars Lander Gets a Few Extra Weeks of Science Operations

NASA’s InSight Mars lander uses a seismometer to study the inner layers of Mars. Seismic signals from quakes change as they pass through different kinds of materials; seismologists can “read” the squiggles of a seismogram to study the properties of the planet’s crust, mantle, and core.

This Electronic Tattoo Can Measure Your Blood Pressure Better Than a Smartwatch

Getting a new tattoo isn’t only about looking cool (or making a decision you’ll regret years later)—it could also save your life. At least, that’s the idea behind a new electronic tattoo that can continuously and unobtrusively measure your blood pressure. In a paper published Monday in the journal Nature Nanotechnology, a team from the …

Deciding to Read This Article Isn’t The Result of Gravity Crushing Your Quantum Spirit

A few years ago, deep beneath the Apennine Mountains in Italy, a team of physicists hunted for flashes of light that just might suggest human consciousness is the product of gravitational forces. The fact they came up empty-handed doesn’t mean we’re all meat computers with no free will; it does make the quest for a …

Physicists Build Atom Laser That Can Stay On Forever

University of Amsterdam physicists build an atom laser that can stay on forever. Credit: UVA These days, imagining our everyday life without lasers is difficult. Lasers are used in printers, CD players, measuring devices, pointers, and so on. What makes lasers so special is that they use coherent waves of light: all the light inside …

Dead Star Caught Violently Tearing Up Planetary System

This illustration shows a white dwarf star siphoning off debris from shattered objects in a planetary system. The Hubble Space Telescope detects the spectral signature of the vaporized debris that revealed a combination of rocky-metallic and icy material, the ingredients of planets. The findings help describe the violent nature of evolved planetary systems and the …

Weird Star Produces the Fastest Nova on Record

This illustration shows an intermediate polar system, a type of two-star system that the research team thinks V1674 Hercules belongs to. A flow of gas from the large companion star impacts an accretion disk before flowing along magnetic field lines onto the white dwarf.

Low-cost Astra rocket suffers upper stage failure, two NASA satellites lost

California-based Astra on Sunday launched two shoebox-size NASA satellites from Cape Canaveral in a modest mission to improve hurricane forecasts, but the second stage of the company’s low-cost booster malfunctioned before reaching orbit and the payloads were lost. “The upper stage shut down early and we did not deliver the payloads to orbit,” Astra tweeted. …
