Betelgeuse's elusive companion star: Siwarha's 'wake' detected
Using new observations from NASA's Hubble Space Telescope and ground-based observatories, astronomers have tracked the influence of a recently discovered companion star, Siwarha, on the gas around Betelgeuse. The research, by scientists at the Center for Astrophysics | Harvard & Smithsonian (CfA), reveals a trail of dense gas swirling through Betelgeuse's vast, extended atmosphere, shedding light on why the giant star's brightness and atmosphere have changed in strange and unusual ways.

Jupiter's moon Europa lacks the undersea activity needed to support life, study suggests
The giant planet Jupiter has nearly 100 known moons, yet none have captured the interest and imagination of astronomers and space scientists quite like Europa, an ice-shrouded world that is thought to possess a vast ocean of liquid salt water. For decades, scientists have wondered whether that ocean could harbor the right conditions for life, placing Europa near the top of the list of solar system bodies to explore.

The moon has been secretly feasting on Earth's atmosphere for billions of years
A new study reveals that tiny fragments of Earth's atmosphere are transported to and absorbed by the moon via gusts of solar wind and our planet's magnetic field, upending a 20-year-old theory based on NASA's Apollo lunar samples.

Venus reaches superior solar conjunction today: What does it mean and can you see it?
A solar conjunction occurs as Venus' orbit carries it into alignment with the sun and Earth.
Active solar region observed for record 94 days
In May 2024, the strongest solar storm in twenty years raged. An international team led by ETH Zurich observed it. Their findings are now helping to improve space weather forecasts.

Hubble examines Cloud-9, first of new type of object
A team using the NASA/ESA Hubble Space Telescope has uncovered a new type of astronomical objectโa starless, gas-rich, dark-matter cloud that is considered a "relic" or remnant of early galaxy formation. Nicknamed "Cloud-9," this is the first confirmed detection of such an object in the universe. The finding, published in The Astrophysical Journal Letters, furthers the understanding of galaxy formation, the early universe, and the nature of dark matter itself.
