The Vera C. Rubin Observatory has officially begun its 10-year sky survey, promising to generate millions of astronomical alerts nightly. Meanwhile, new Webb images reveal Uranus in unprecedented detail, and the Artemis program faces timeline adjustments.
The James Webb Space Telescope has detected an ancient galaxy, JADES-GS-z13-0, existing just 320 million years after the Big Bang. Its surprising maturity challenges current theories about the rapid formation of early galaxies.
Exploring Earth's planetary status, the impossibility of figure-8 orbits, the ongoing debate about dark matter's composition, and the future of human spaceflight.
Fraser Cain of Universe Today hosted a live Q&A session on March 1st, 2026, delving into exoplanets, orbital mechanics, and the search for extraterrestrial life. The event highlighted Universe Today's commitment to making space science accessible.
The concept of dark matter is rooted in a wealth of observational data, not mere theory. Scientists are using new tools to unravel this cosmic mystery, while also clarifying phenomena like the Great Attractor and the extreme climate of Venus.
Earth faces a profound transformation over the next billion years, primarily driven by the Sun's increasing luminosity. This will lead to dramatic climate shifts, the loss of oceans, and ultimately, the extinction of all life on our planet.
The discovery of Eris, a massive object in the outer solar system, challenged the definition of a planet. This led to the IAU's 2006 decision to reclassify Pluto as a dwarf planet and establish new criteria for planetary status, expanding our understanding of the solar system's diverse populations.
Interstellar visitor 3I/ATLAS has revealed surprising details about its composition and behavior. Passing near the Sun, it exhibited intense outgassing and color changes, and was confirmed by radio telescopes to be a water-rich comet, not an artificial object. Its unique chemistry suggests it has been "cooked" by cosmic rays over billions of years.
The James Webb Space Telescope has captured the first direct image of planet formation in action around the young star HOPS-315. This breakthrough observation reveals the crucial moment when gas condenses into solid material, offering unprecedented insights into the earliest stages of planetary system development and providing a potential mirror to our own solar system's birth.
Astronomers may have found the first evidence of the elusive Planet Nine, a massive hypothetical world in the outer solar system. New analysis of decades-old infrared data reveals a single candidate object, but further observation is needed for confirmation.
