Bedtime Astronomy

How do giant planets end up orbiting dangerously close to their stars? New simulations suggest that supersonic shock waves in their atmospheres can drain orbital energy, driving planets inward.

Depending on the intensity of these disruptions, a planet may settle into a tighter orbit or lose much of its atmosphere. This mechanism could help explain the mysterious distribution of hot Jupiters and other giant exoplanets.

Could comets have delivered the ingredients for life on early Earth? A University of Cambridge study challenges this long-standing theory, suggesting that high-speed impacts may have destroyed fragile organic molecules before they could trigger prebiotic chemistry.

Mars may have offered more favorable conditions, but the findings raise new questions about how life’s essential building blocks first appeared.

Astronomers analyzing data from the Vera C. Rubin Observatory have identified a massive icy object beyond Neptune that could be a new dwarf planet.

Provisionally named 2026 ED138, the distant world remained hidden among crowded background stars until advanced search algorithms revealed its movement across a decade of archival images. If future observations confirm its shape, it could become another recognized member of the solar system’s dwarf planet family.

New radio observations reveal that Betelgeuse’s atmosphere has largely recovered from its mysterious 2019 dimming. But astronomers have uncovered another intriguing clue: a companion star called Siwarha, whose orbit appears to create a distinctive wake inside the supergiant’s atmosphere. Further observations could reveal how this hidden stellar interaction works and offer new insights into the final stages of massive stars.

The scorching exoplanet TOI-561 b is challenging expectations about worlds beyond our solar system.

Using the James Webb Space Telescope, astronomers have uncovered surprising clues about its atmosphere, where reflective mineral clouds may shield the planet from intense stellar radiation. With a surface of molten rock, this extreme world could reveal new insights into how atmospheres survive under the harshest conditions.
