Bedtime Astronomy

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.

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.

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’ biggest mysteries.

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 past, offering a glimpse into how galaxies evolve.

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 that the primordial space environment was far more chemically diverse than scientists expected.
