Bedtime Astronomy

Plants begin changing their genetic activity almost immediately after entering space. In a suborbital flight experiment, researchers identified changes in more than 1,200 genes in Arabidopsis plants, revealing how roots and leaves respond to spaceflight stress.

The findings offer new insights into growing plants beyond Earth and demonstrate how commercial spacecraft could advance biological research in space.

The James Webb Space Telescope has revealed that gas surrounding Sagittarius A*, the supermassive black hole at the center of the Milky Way, is surprisingly rich in heavy elements.

Researchers at McGill University found chemical similarities between this gas and nearby stars, suggesting they may share a common origin. These metals influence how gas cools and flows toward the black hole, offering clues to why it consumes matter so slowly. However, scientists warn that local environmental conditions can distort these emissions, making them unreliable evidence of past black hole outbursts.
