NASA’s PUNCH mission has captured striking views of Comet Lemmon as it passed close to the Sun in late 2025. The observations show how solar wind and eruptions reshape a comet’s tail, sometimes causing it to break and regrow. The images provide valuable insight into how solar activity affects objects across the inner solar system.

Hubble has captured a glowing plume of gas escaping the spiral galaxy NGC 4388 in the Virgo cluster. Moving through hot intracluster gas, the galaxy sheds material, partially energised by its central black hole. Multi-wavelength observations reveal the impact of both environmental forces and central activity on galaxy evolution.
