Illustration depicting the life cycle of a star, from the formation in a stellar nursery like the Lupus 3 cloud, to infancy as T Tauri stars, and finally to a planetary nebula phase illustrated by the Helix Nebula, highlighting the process of cosmic recycling.
A breathtaking Webb image captures the vastness of deep space, showcasing an array of galaxies in dazzling shapes and colors. Prominent blue spirals and pale elliptical galaxies stand out among a sea of medium-sized orange and red galaxies, with even smaller and fainter celestial bodies scattered like cosmic confetti.

Ground-based VISTA and space-based Webb telescopes capture the Helix Nebula from different perspectives. The left image shows the nebula's expansive view, with a highlighted section showing Webb’s detailed examination on the right.
Proba-3's eclipse technology captures the solar corona in breathtaking detail.
A tranquil tapestry of cosmic gas and dust, teeming with hidden star formation activity.
What if a galaxy could exist without the brilliant stars that normally make galaxies visible? Cloud-9 may offer astronomers one of the most intriguing examples yet. Located near the spiral galaxy M94, this mysterious hydrogen-rich object appears to contain enormous amounts of gas while producing almost no detectable starlight.
Astrophysicists have completed ASTRID, the largest cosmological hydrodynamic simulation ever run, tracing the universe from the cosmic dawn ($z=99$) down to the present day ($z=0$). By resolving 166 billion particles across 815 million light-years, ASTRID unveils how supermassive black holes co-evolve with galaxies and sculpt the cosmic web.
Scientists have uncovered the first robust evidence of a black hole and neutron star crashing together while orbiting in an oval path, challenging long-standing assumptions about cosmic pair formation.
Most neutron star-black hole pairs are expected to adopt circular orbits long before merging, their orbits slowly rounded out by the constant emission of gravitational waves over millions of years.
