Ahead Of Closest Approach To Earth, A Look At 3 Latest Images Of Interstellar Comet 3I/ATLAS
The comet was detected on July 1, 2025, by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey telescope in Chile.

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.

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.

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...

Alpha Centauri May Have Sent Millions of Asteroids into the Solar System
A study proposes that Alpha Centauri could be contributing a significant number of asteroids to the solar system. Simulations indicate that around 50 objects from the neighboring star system may enter the Oort Cloud annually. While most pass through due to their high velocity, a few could travel inward. The frequency of such occurrences is expected...

Over 10 Lakh Statue Of Liberty-Sized Alien Objects Lurking Outside Solar System
Simulations showed that over 10 lakh macroscopic objects, each wider than 100 metres were moving surreptitiously outside our cosmic backyard.

Organic Molecules in Space: A Key to Understanding Life's Cosmic Origins
Organic molecules, the building blocks of life, have been discovered across space—from interstellar clouds to asteroids and comets. Findings from missions like Rosetta, Hayabusa2, and Osiris-Rex reveal that these compounds existed long before the Sun formed. Scientists believe organic molecules survived planetary formation in protoplanetary disks...

Asteroids Impacting Neutron Stars May Be the Cause of Fast Radio Bursts
Research suggests asteroid impacts on neutron stars may be the cause of mysterious fast radio bursts (FRBs). These collisions release enormous energy and match observed FRB frequency. Scientists believe interstellar objects colliding with neutron stars could account for their rate and occurrence, while repeating FRBs may stem from asteroid belts. O...

Scientists Discover Interstellar Asteroids Hiding in Our Solar System
Asteroids, like the planets, revolve around the Sun in our Solar System. They have been known to be a part of the Solar System since their origin. But for the first time ever, researchers have found a group of asteroids that originated from outside our Solar System.

Interstellar Gatecrasher 2I/Borisov Is No Ordinary Comet
"This shows that 2I/Borisov is not a completely alien object, and confirms some similarity with our 'normal' comets, so the processes that shaped it are comparable to the way our own comets formed," said Martin Cordiner, an astrobiologist working at NASA's Goddard Space Flight Center.

This Bizarre Asteroid In Jupiter's Orbit Is An Interstellar Immigrant
For billions of years, without our knowing it, scientists say, our solar system has harbored a visitor from another star.
