Comet 3I/ATLAS Larger Than Expected, Could Be Alien Probe: Astrophysicist
Harvard researchers said that interstellar object 3I/ATLAS may be much larger than initially thought and could potentially harbour alien technology.

What Is Heliosphere? NASA's New Mission To Study Sun's Protective Bubble
NASA launched the Interstellar Mapping and Acceleration Probe (IMAP) spacecraft from Kennedy Space Center in Florida on Wednesday, September 24.

NASA IMAP Mission To Explore The Far Reaches Of The Solar System
NASA is gearing up to launch the Interstellar Mapping and Acceleration Probe (IMAP), a mission aimed at exploring the farthest reaches of our solar system.

Mystery Green Glow: Interstellar Comet 3I/ATLAS Puzzles Scientists With Change In Colour
3I/ATLAS was discovered on July 1 by the Asteroid Terrestrial-impact Last Alert System (ATLAS) at a distance of 675 million kilometres from the Sun.

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.

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.

NASA Shares New Details About Interstellar Comet 3I/ATLAS That's Hurtling Towards Earth
Hubble also captured a dust plume ejected from the Sun-warmed side of the comet and a hint of a dust tail streaming away from the nucleus.

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.

Harvard Astronomer Avi Loeb Suggests Interstellar Object Could Be Alien Probe
A senior Harvard astronomer has reignited speculation about the origins of a vast interstellar object hurtling through the solar system. He has suggested that it might be an engineered probe instead of a natural phenomenon.
