Astronomers using the FAST telescope have discovered the lowest-mass double neutron star system ever recorded, which is losing energy via gravitational waves. Astronomers using the Five-hundred-meter Aperture Spherical Telescope (FAST) have identified...

rays but suffer more intense, destructive gas collisions. Consequently, an object’s ability to survive the journey to our solar system is a delicate trade-off between its speed, composition, and the density of the interstellar medium it traverses....

The James Webb Space Telescope has detected an interstellar visitor hiding within a comet’s icy grains, challenging everything we know about space rocks. The James Webb Space Telescope has uncovered a distinct chemical fingerprint in the interstellar...

investigation by the Hubble and James Webb Space Telescopes has uncovered a surprising truth about the deep reaches of our solar system: some of the smallest, most distant icy bodies appear to be pristine time capsules from the dawn of planetary...

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...

Study shows Uranus’s odd rotation stretches its bow shock, causing it to expand and contract every planetary day. New simulations reveal that the ice giant Uranus reshapes its bow shock on a daily basis, driven by the planet’s extreme axial tilt and an...

radial‑velocity method to a brown dwarf—rather than a conventional star—marks a first in the search for moons beyond our Solar System. While the detection does not yet constitute a formal exomoon confirmation, it provides a compelling candidate for...

suggest the Sun’s final act will be surprisingly turbulent, upending previous theories about the dramatic fate of our solar system’s planets. New astrophysical modeling suggests that our solar system’s outer giants may face a far more precarious future...

Webb data hint Neptune’s tiniest moons could be relics of an ancient satellite system shattered by a violent cosmic event billions of years ago. New observations from the James Webb Space Telescope indicate that the tiny inner moons of Neptune may be...

evidence from deep within Uranus and Neptune suggests these distant ice giants may have formed in different parts of our solar system. Uranus and Neptune have long been considered the quintessential planetary twins of our solar system. Positioned far...

Why This Changes Everything This discovery forces scientists to reconsider the physical makeup of the small bodies in our solar system. If these asteroids are not flying apart at 1.9-minute rotation speeds, they must have some form of internal cohesion....

JWST has captured an icy Centaur warming up after a Saturn encounter, potentially transforming the distant world into an active comet. Deep in the outer reaches of the solar system, more than 3 billion miles from our planet, a small, frozen body is...

a great opportunity to study what happens to planets at these cooler temperatures.” He continued, “Most planets in our solar system have almost circular orbits, but this new planet follows a slightly more unusual and oval-shaped path. At its closest...

detected radio waves from an exoplanet, marking the first time a magnetic field has been measured on a world beyond our solar system. Astronomers have achieved a milestone in planetary science by capturing the first direct radio emissions from an...

have discovered two distinct gas rings around a white dwarf, suggesting hidden planets could hold the key to our Solar System’s final fate. Astronomers have uncovered a highly unusual configuration surrounding a white dwarf, revealing two distinct rings...

Six toaster-sized satellites will synchronize to form a giant radio telescope, helping scientists study solar eruptions that threaten space missions. NASA is preparing to launch an ambitious mission that will reconfigure how we monitor the Sun,...

a gravity-assist maneuver, utilizing Earth’s gravitational pull to slingshot itself further into the depths of our Solar System. This high-stakes orbital adjustment serves as a critical milestone in the spacecraft’s multi-year trek toward Jupiter, where...

moons—along with the distant Earth, the photo visually conveys the vast differences in scale and distance that define our solar system. Phobos continues to attract intense study because of its irregular shape, rapid orbital decay, and ambiguous origin,...

Astronomers discover a unique planetary system around a nearby star, featuring traits unlike any previously known exoplanets. A new study published in Monthly Notices of the Royal Astronomical Society offers the most comprehensive look yet at the...

A newly mapped channel of hot plasma may link our solar system to distant stars, offering fresh clues about the Milky Way’s complex structure. Astronomers have identified what appears to be a vast, low-density pathway of hot plasma extending from our...
