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.

Scientists Say Missions to Interstellar Comets Like 3I/ATLAS Are Feasible With Existing Tech
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.

TARS: Sunlight-Powered Space Slingshot Could Propel Tiny Probes to the Stars
Astronomer David Kipping has proposed TARS, a sunlight-driven space slingshot. Using reflective panels spun in space, it can fling small probes at escape speed. Though Alpha Centauri is over a thousand years away, this simple, fuel-free idea could pave the way for future interstellar missions.

Could a Planet Exist Without a Host Star? Astronomers Say Rogue Worlds May Roam Freely
Astronomers have discovered that planets can survive without stars, drifting as rogue or hypervelocity worlds. Some are flung into space by black holes, while others are displaced by gas giants. On some of these rogue worlds, the idea goes, there might be oceans beneath icy crusts, where life, at least life at a microbe level, could exist.

NASA's Hubble Captures Interstellar Comet 3I/ATLAS Ahead of Close Mars Flyby
On October 3, 2025, interstellar comet 3I/ATLAS will pass just 30 million km from Mars — nine times closer than from Earth. ESA’s Mars Express and TGO, along with NASA and China’s orbiters, will attempt to image its coma, analyze gases, and study this rare visitor from beyond the solar system.

NASA’s OSIRIS-REx Mission Finds Stardust in Asteroid Bennu Older Than the Solar System
NASA’s OSIRIS-REx mission has found presolar stardust grains inside Bennu’s samples. These tiny particles, older than the Sun, carry chemical fingerprints of ancient stars and interstellar space. Bennu thus serves as a pristine time capsule, preserving the earliest clues to the birth of our solar system.

James Webb Detects Carbon Dioxide–Dominated Coma in Interstellar Object 3I/ATLAS
The James Webb Space Telescope observed 3I/ATLAS, the third interstellar object detected in our solar system. Its coma is unusually rich in carbon dioxide with little water or carbon monoxide, suggesting a COâ‚‚-rich core or an insulating crust. Findings raise new questions about its cosmic origin.

Powerful Space Telescope Observes Interstellar Object, Finds CO2 And Water
NASA explained that the object has been categorised as interstellar because of the hyperbolic shape of its orbital path.

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.

Hubble Takes Best Picture Yet Of Comet From Another Solar System
The Hubble Space Telescope has captured the best picture yet of a high-speed comet visiting our solar system from another star.

Harvard Scientist Claims Rare Interstellar Object Might Be "Alien Technology"
The comet will reach its closest point to the Sun (perihelion) on October 29, 2025, passing just inside Mars' orbit

Hubble Captures First Images of Ancient Interstellar Visitor Comet 3I/ATLAS
Hubble has captured images of comet 3I/ATLAS, an ancient interstellar object likely 7 billion years old. As only the third known visitor from beyond the solar system, it offers rare insights into distant planetary systems. With its water ice and D-type asteroid-like dust, 3I/ATLAS is now under global scientific scrutiny before it vanishes back into...

Gemini North Telescope Spots Interstellar Comet 3I/ATLAS Racing Through Solar System
Gemini North has imaged 3I/ATLAS, the third interstellar object to enter our solar system. Larger than its predecessors and possibly older than our solar system, the comet will pass closest to the Sun on Oct. 30 before returning to deep space. Scientists worldwide are racing to gather data during its brief visit.

ESO Captures Clear Images of Interstellar Comet 3I/ATLAS Using VLT
The European Southern Observatory’s Very Large Telescope has captured the clearest images so far of comet 3I/ATLAS, an interstellar visitor first spotted on July 1, 2025. Identified by its hyperbolic orbit, the comet is only the third interstellar object recorded passing through our solar system. The VLT’s deep image and timelapse confirm it is...

Crystalline Ice Discovered in Space: New Study Reveals Hidden Order in Cosmic Ice
A groundbreaking study from University College London and the University of Cambridge reveals that water ice in space, long believed to be completely amorphous due to extreme cold, may actually contain up to 25% crystalline structure. Simulations and X-ray diffraction experiments confirm the presence of nanocrystals in so-called low-density amorpho...
