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.
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.
Far from the warmth of any star, moons orbiting rogue gas giants might harbor oceans of liquid water—and potentially complex life—for billions of years.
Liquid water is considered essential for life. Surprisingly, however, stable conditions that are conducive to life could exist far from any sun.
Look up on a clear night and you'll see the streaks of our modern satellite networks. What you don't see is the growing fallout for the atmosphere that keeps us alive.
A wave of satellite launches and reentries is changing the chemistry and physics of the middle and upper atmosphere. Studies warn of ozone depletion, stratospheric heating, and new metal aerosols from burning spacecraft.
