Betelgeuse and the Crab Nebula Reveal Stellar Death and Rebirth in Multi-Telescope Views

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 Captures Gas Escaping Sideways Spiral Galaxy NGC 4388 in Virgo Cluster

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.

Electricity-Driven Nitrogen Insertion Opens a Sustainable Path to Drug-Ready Heterocycles

Scientists at the National University of Singapore have developed an electricity-driven method to insert nitrogen into stable carbon rings, enabling greener synthesis of valuable heterocycles. Published in Nature Synthesis, the approach avoids harsh chemicals, reduces waste, and allows access to key drug-ready molecular frameworks under mild conditions.
