A busy week on the Space Coast saw two rockets launch within hours of one another as both SpaceX and United Launch Alliance had missions to proliferate a pair of competing satellite constellations. Go to Source Interference from human activity has always been a sticking point in astronomical observations. Radio astronomy is notoriously sensitive to unintentional interference—hence why there are “radio silent” zones near telescopes where cell phones are banned. But gravitational wave astronomy is affected to an even worse degree than radio astronomy, according to a new paper published on […] Manuel Linares is a physicist at NTNU who studies binary stars called “spider pulsars.” The stars got this name because they could eat their partner, just like some spiders do. Go to Source An expensive lunar rover that once had its moon trip canceled has a ride once again. Go to Source SpaceX’s sunrise launch from Cape Canaveral on Sunday was the 80th launch of the year on the Space Coast, which is on track to break the annual record and surpass 100 for the year. Go to Source An international team of astronomers has conducted detailed multicolor photometric and spectroscopic observations of SN 2022xlp—a type Iax supernova. Results of the observational campaign, published September 9 on the arXiv pre-print server, could shed more light on the nature of this rare subclass of supernovae. Go to Source A discovery involving researchers at The University of Hong Kong (HKU) has, for the first time, revealed millisecond pulsations hidden within a powerful cosmic explosion known as a gamma-ray burst (GRB). Go to Source With help from amateur astronomers, scientists tracked how an asteroid traveled from space, broke up in Earth’s atmosphere and sent fiery fragments shooting to the ground, gathering new information about how these space rocks disintegrate. Go to Source When the ESA launched the Gaia spacecraft in 2013, it didn’t generate the same fanfare as the launch of other missions like the JWST, or first light from telescopes like the Vera Rubin Observatory. That’s largely because Gaia doesn’t capture gorgeous images of celestial objects like other telescopes. Instead, Gaia was an astrometry mission. Go […] A new class of supermassive black holes embedded in a thick gas shell could explain small red dots in images from the James Webb Space Telescope. Go to Source A new NASA mission will capture images of Earth’s invisible “halo,” the faint light given off by our planet’s outermost atmospheric layer, the exosphere, as it morphs and changes in response to the sun. Understanding the physics of the exosphere is a key step toward forecasting dangerous conditions in near-Earth space, a requirement for protecting […] The first model of the European Space Agency’s (ESA) reusable rocket demonstrator Themis is standing at its launch pad in Kiruna, Sweden. Go to Source Researchers from the Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences have revealed for the first time how gas flows from vast distances toward the disk surrounding a nascent massive star in the process of star formation. Go to Source Gamma-ray bursts (GRBs) are the brightest explosions in the universe. In just a few seconds, they can outshine all the stars in their host galaxy combined, releasing more energy than our sun will emit over its entire lifetime. Yet, despite decades of observations, key mysteries remain unsolved: What powers the prompt emission? What is the […] Of the many roads leading to successful Artemis missions, one is paved with high-tech computing chips called superchips. Along the way, a partnership between NASA wind tunnel engineers, data visualization scientists, and software developers verified a quick, cost-effective solution to improve NASA’s SLS (Space Launch System) rocket for the upcoming Artemis II mission. This will […] |
