Interstellar Comet 3I/ATLAS Shows Wobbling Jets in Rare Sun-Facing Tail, Surprising Astronomers
Astronomers have detected strange wobbling jets in the rare sun-facing tail of interstellar comet 3I/ATLAS. Observed as the comet neared the Sun, the shifting jets reveal new details about how material escapes from comets formed around other stars, offering rare insight into alien planetary systems.

Scientists May Finally Explain Mysterious Crown-Like Features on Venus
Venus’ distinctive crown-like coronae may be explained by heat trapped beneath a rigid mantle layer, according to recent studies. This discovery provides key insights into the planet’s geological activity and helps researchers compare Venus’ surface evolution to that of other planets in our solar system

Scientists Propose Space Missions to Chase Down Interstellar Comets
A Southwest Research Institute study reveals that chasing interstellar comets like 3I/ATLAS is achievable with current rockets and instruments. Such missions could collect data on comet nuclei and comae, providing clues to the formation of other star systems. International collaborations make these rare, high-value missions increasingly realistic.

Asteroids vs Comets vs Meteors vs Meteorites: What Are They and How Are They Different From Each Other?
Asteroids, comets, meteoroids, meteors, and meteorites may seem similar, but each plays a unique role in the Solar System. Asteroids are rocky remnants, comets are icy wanderers, meteors are shooting stars, and meteorites are fragments that survive the plunge to Earth.

Mercury Has Shrunk by Several Kilometers Over Billions of Years, Scientists Report
Mercury’s surface reveals it has been shrinking for billions of years due to cooling and faulting. A new study estimates the planet’s radius has contracted by 2.7–5.6 kilometers, offering the most precise figures yet. The findings sharpen understanding of Mercury’s thermal evolution and could help scientists apply the same techniques to tec...

Hubble Delivers Best View Yet of Rare Interstellar Comet 3I/ATLAS Racing Through Solar System
Hubble has captured its sharpest image of 3I/ATLAS, a rare interstellar comet speeding through the solar system at 130,000 mph. The view reveals a dust-filled coma, a faint tail, and activity similar to native comets. Astronomers aim to study its composition before it vanishes forever, offering insight into objects formed around other stars.

Mysterious Planet Nine May Still Lurk in the Outer Solar System
Astronomers have long speculated about a hidden planet—Planet Nine—lurking beyond Neptune. First proposed in 2016, the theory explains the strange orbits of distant Kuiper Belt objects through the gravitational pull of a massive, unseen world. Caltech researchers remain confident, while others suggest alternatives like debris rings or even a bl...

NASA’s IMAP Spacecraft Gears Up for Mission to Explore Solar System’s Edge
NASA’s Interstellar Mapping and Acceleration Probe (IMAP) has begun final preparations at Kennedy Space Center for a launch no earlier than September 2025. The mission will position IMAP at Lagrange Point 1, a million miles from Earth, to study the solar wind and the edge of the heliosphere. The spacecraft, built by Johns Hopkins APL, will fly al...

Asteroid Vesta May Be a Fragment of a Lost Planet, Say Scientists
Vesta, once believed to be a stalled protoplanet, may be a fragment of a long-lost differentiated planet. Using refined gravity data from NASA’s Dawn mission, scientists found it lacks a dense core, suggesting it was ejected during a primordial impact. This revised view may apply to other asteroids and reshape planetary formation theories.

Most Promising "Hints" Of Potential Life Detected On Distant Planet
Astronomers announced Thursday that they had detected the most promising "hints" of potential life on a planet beyond our solar system, though other scientists expressed skepticism.
