Bedtime Astronomy

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 eventually interstellar space?

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.

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.

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.
