Betelgeuse’s unusual dimming and the Crab Nebula’s remnants offer insight into stellar death and rebirth. Composite images from multiple telescopes show gas filaments and a neutron star, illustrating how massive stars explode, enrich space with heavy elements, and seed future star formation. These observations help scientists trace stellar life cycles in the unive...

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.

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.
