Bedtime Astronomy

Scientists are taking a closer look at Kallichore, one of Jupiter’s smallest and least understood moons, ahead of potential exploration by ESA’s JUICE spacecraft.

By refining its orbit and physical characteristics, researchers reduced positioning errors by 80%, helping enable a possible future flyby. This tiny, dark world could offer rare clues about the early solar system.

Could the universe be slowing down rather than accelerating?

A new study from Yonsei University challenges the standard picture of cosmic expansion, arguing that age-related biases in Type Ia supernovae may have distorted previous conclusions. The findings add fuel to the growing debate over dark energy and the evolution of the universe, while proposing a new way to test the competing explanations.

After an eight-year journey across billions of kilometers, BepiColombo is entering its final approach to Mercury.

The mission has completed a crucial autonomous maneuver and is preparing to place two spacecraft around the mysterious planet later in 2026.

Their observations could reveal new clues about Mercury’s magnetic field, enormous iron core, and the origins of rocky planets.

A mysterious gamma-ray signal from distant galaxy clusters may be offering one of the strongest clues yet to the nature of dark matter.

Researchers from the Chinese Academy of Sciences found a distinct energy spike consistent with predictions for WIMPs, while struggling to explain it through conventional astrophysical sources or instrumental effects.

Although the signal still needs confirmation, its unusual characteristics could point researchers toward the long-sought invisible matter dominating the universe.

New astronomical simulations suggest that Earth-like planets may be far more common than previously thought.

By allowing planets to form from randomized starting conditions, researchers found that worlds resembling Earth, Venus, and Mars can naturally emerge around other stars. The findings offer new clues about how habitable planets form—and how common life-friendly environments might be across the universe.
