Astronomers using the XRISM X-ray observatory have captured rare details of a neutron star feeding on the powerful stellar wind of a massive blue hypergiant 13,000 light-years away. The observations reveal plasma racing toward the neutron star at about 335,000 mph, creating intense X-ray flares and a turbulent accretion disk. The discovery offers an unprecedented look at how matter behaves under e...

SpaceX’s Starship enters another critical phase as its 14th flight attempts to push the massive spacecraft closer to true orbital operations.

NASA’s Perseverance rover has uncovered evidence that water transformed Mars in at least three distinct episodes. In Jezero Crater’s Margin Unit, the rover found igneous rocks containing carbonates and silica—clues to ancient groundwater, a long-vanished lake, and later heated fluids underground. The discovery reveals a far more complex watery history for Mars and raises new questions about whethe...

Cornell students have successfully tested tiny solar sails in orbit using miniature ChipSats and 3D-printed spacecraft. Their Alpha CubeSat and Sailing to the Stars missions demonstrated how sunlight can propel ultra-light spacecraft, while testing low-cost navigation and deployment technologies. Could these tiny sails become a stepping stone toward future missions across the solar system—and even...

A new study suggests Venus may once have had a moon that eventually spiraled inward and crashed into the planet. Simulations show that Venus’s slow rotation could make moons unstable, offering a possible explanation for its unusual evolution and raising questions about moons around other slowly rotating planets. Thank you for listening to Bedtime Astronomy — your guide to the cosmos. New episodes...

Computer simulations show that massive collisions can reshape icy moons without necessarily destroying their hidden oceans. Larger moons may even retain enough heat to thicken their subsurface oceans, while smaller moons could lose insulation and cool down. The findings could help guide future searches for extraterrestrial life. Thank you for listening to Bedtime Astronomy — your guide to the cosm...

Scientists are searching for clues that the universe may be finite and globally connected rather than infinite. By analyzing the cosmic microwave background and galaxy patterns, the COMPACT collaboration is looking for repeating structures that could reveal whether traveling far enough through space might eventually bring you back to where you started. Thank you for listening to Bedtime Astronomy...

Researchers have proposed using entangled superconducting qubits to search for axions, hypothetical particles that could explain dark matter. The idea is to detect tiny quantum-state rotations caused by these elusive particles and extract the signal from quantum noise using advanced statistical methods. If successful, quantum computers could become powerful new detectors for one of physics’ bigges...

Hubble has captured a striking view of NGC 4698, a spiral galaxy about 55 million light-years away in the Virgo Cluster. Unlike most galaxies, its central bulge rotates almost perpendicular to its main disk. Astronomers believe this unusual structure may have been caused by an interaction with another galaxy or the capture of external gas. A hydrogen tail provides further clues to its turbulent pa...

Researchers have uncovered tens of thousands of organic compounds inside the Murchison and Aguas Zarcas meteorites using the world’s highest-resolution mass spectrometer. Atomic force microscopy also revealed rare images of individual extraterrestrial molecules in remarkable detail. The findings suggest that the chemical ingredients needed for life were widespread across the early solar system—and...

New research suggests that black holes of vastly different sizes follow the same rule when launching powerful radio jets. By studying stars torn apart by black holes, scientists found that jets appear when the feeding rate falls below a critical threshold. The discovery reveals a surprising universal pattern in how matter falls into black holes and could help astronomers predict when these powerfu...

VT J1906+0849 is a mysterious radio source in the Milky Way that has remained active for more than 20 years, repeatedly brightening while producing no detectable X-rays. Astronomers believe it may involve a black hole or neutron star feeding on surrounding matter, with a dense disk wind hiding its central engine while powering powerful radio jets. The object could represent a previously unknown cl...

The Moon could support permanent human settlements, but its resources may place strict limits on how large they can become. Near-constant sunlight at the lunar poles could provide abundant energy, yet limited water ice could prevent the growth of large cities and heavy industry. Future lunar civilizations may need hidden water reserves, imported resources, or radically better recycling to expand b...
