Modeling quark star merger ejecta: Study reveals three possible outcomes

A recent Physical Review Letters study presents a new model for quark star merger ejecta that could resolve whether these cosmic collisions generate ordinary matter or something different.

Clues from the deep sea that an exploding star sent debris to the Earth 10 million years ago

Scientists trying to work out whether a star exploded and the resulting debris crashed into Earth 10 million years ago may be one step closer to solving the mystery. They discovered an unusual amount of Beryllium-10 (10Be) at the bottom of the Pacific Ocean, which may be explained by a supernova, an exploding star.

Scientists discover first evidence of lava tubes on Venus

Venus is often called Earth’s “sister planet” because of their similarities in size, mass, and composition. Both are rocky worlds that formed about the same time in the inner solar system; however, despite these similarities, Venus evolved into a world vastly different from Earth, with surface temperatures around 465°C, crushing atmospheric pressure 90 times greater […]

Space dust is spongier than we thought, say scientists

Cosmic dust—the tiny particles that help form stars, planets and the chemical building blocks of life—might be much spongier and fluffier than long assumed, according to an international group of scientists.

Two Neptune-sized exoplanets discovered around a young sun-like star

Using NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered two new exoplanets around a young sun-like star known as TOI-6109. The newfound alien worlds are slightly larger than Neptune and orbit their host in less than 10 days. The finding was presented in a paper published September 18 on the arXiv pre-print server.

JWST searches for stars in a glowing gas cloud

Star formation is a fundamental physical process in our universe. Stars light up the cosmos, and give rise to planets, some of which may support life. While humans have no doubt wondered about stars since prehistoric times, new technological tools like the Milky Way have taken our natural curiosity to a whole new level. Now […]

Rogue planet SIMP-0136 displays strong auroral activity similar to Northern Lights

Strong Northern Lights-like activity is the standout feature of today’s weather report, which is coming at you from a strange, extrasolar world, instead of a standard TV studio. That is thanks to astronomers from Trinity College Dublin, who used the NASA/ESA/CSA James Webb Space Telescope to take a close look at the weather of a […]

Double launch day complete with SpaceX, ULA successes

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.

Gravitational wave detectors affected by daylight savings time

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 […]

New catalog compiles more than 100 ‘spider’ pulsars that consume stellar partners

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.
