Astronomers have discovered fast-moving sodium clouds in the young PDS 70 system, suggesting comets are actively transporting water to new planets. A distant stellar system, located 370 light-years away, appears to be mirroring the early history of our...

realized that the prospector had not found gold, but rather a rare, 4.6-billion-year-old relic from the dawn of the solar system. An Astronomical Case of Mistaken Identity Geologists at the museum, who frequently evaluate rocks brought in by the public,...

could have once hosted a substantial satellite, born from a violent collision during the chaotic early history of the solar system, only for that moon to be slowly dismantled by the very gravitational forces that governed its orbit. The study, led by...

A new observing technique has allowed scientists to identify carbon dioxide in the atmospheres of distant giant planets from Earth’s surface, offering a powerful alternative to space telescopes. More than 5,000 planets have now been confirmed beyond...

for planetary classification. As Zurlo points out, “We have a clear delineation between the planets and the Sun in the Solar System, so defining things like moons is simple. In the CD-35 2722 system, where we are blurring the lines between stars,...

Webb telescope observations of interstellar comet 3I/ATLAS reveal unique dusty ice, suggesting shared planet-building blocks across distant solar systems. Data captured by the James Webb Space Telescope (JWST) has unveiled a curious composition within...

Watch as the Moon passes in front of Jupiter during a rare predawn lunar occultation on October 6, visible to observers across parts of North America. Skywatchers across large swaths of North America are in for a rare celestial display on the morning...

Violent eruptions on a distant red giant reveal how a stellar companion and magnetic forces combine to trigger extraordinary, powerful superflares. Astronomers have finally pinpointed the physical processes responsible for some of the most intense...

New impact simulations are reshaping our understanding of moon formation, providing researchers with vital clues to finally pin down when the event occurred. New Simulations Challenge Long-Held Theories on the Moon’s Violent Origins For decades, the...

2722 system. The findings, published in Nature, may constitute the first credible detection of an exomoon outside the Solar System. A Multi‑Component System That Defies Classic Labels The host star of the CD‑35 2722 system is about half the mass of the...

The James Webb Space Telescope has captured a distant supernova, offering new insights into how massive stars died in the early universe. Astronomers have leveraged the unparalleled sensitivity of the James Webb Space Telescope (JWST) to detect one of...

goals and prepares the fleet for a voyage that could reshape current models of solar activity and its influence across the Solar System. Rationale Behind the Launch Vehicle Change Switching the SunRISE payload to Falcon Heavy reflects more than a...

interiors of the progenitor bodies. “We see something that doesn’t really look like anything else we’ve identified in the solar system; it doesn’t match anything we have in our spectral libraries,” Davis explains. “We assume it’s some form of hydrated...

A proposed 6,800-mile lunar solar ring could harvest massive amounts of energy and beam it back to Earth, offering a radical solution for global power needs. Tokyo-based construction giant Shimizu Corporation has proposed an ambitious architectural...

A newly discovered star orbiting Sagittarius A* could provide astronomers with a rare, groundbreaking way to measure the Milky Way’s central black hole. Astronomers have uncovered a celestial speedster named S301, a star hurtling through the extreme...

The James Webb Space Telescope has revealed that Chariklo’s rings are changing far faster than expected, challenging theories on small-body ring stability. The small, ringed body Chariklo, located in the outer solar system between the orbits of Uranus...

New ultra-deep observations finally unveil the hidden outer regions of a massive galaxy, solving a long‑standing mystery for astronomers. Using the deepest optical exposures ever taken of IC 1101, astronomers have finally delineated the galaxy’s...

NASA’s MAVEN mission uncovers a new magnetic process driving localized auroras on Mars, reshaping our view of the planet’s atmospheric dynamics. NASA’s MAVEN probe has identified a previously unknown magnetic circulation that can generate localized...

mph. This marks a practical transition for a spacecraft that is five years into a mission aimed at probing some of the solar system’s most primitive building blocks. Early Imaging of Remote Trojan Candidates In the spring of 2026, Lucy pointed its...

NASA’s Perseverance rover has captured a rare solar eclipse as Phobos transits the Sun, turning the Martian event into vital new scientific data. NASA’s Perseverance rover has successfully documented a rare solar transit, capturing the Martian moon...
