Planet Nine was previously suggested as a possible explanation for distant orbital clustering. It was thought to be ten times Earth’s mass, orbiting far beyond Neptune.
-
Psyche’s twin cameras recorded long-exposure images of Earth and the Moon. From 180 million miles away, both appeared as faint dots.
-
ur Solar System is wrapped in such a shield, a bubble created by the Sun. Known as the heliosphere, it extends billions of kilometres into space and protects life on Earth.
-
NISAR marks the first joint Earth-observing satellite developed by India and the United States. The observatory will monitor a wide range of changes, including ground shifts caused by earthquakes, landslides, and volcanic activity.
-
The James Webb Space Telescope spotted signs of solid minerals. These are known as silicon monoxide, beginning to cool and harden.
-
NASA's Hubble Space Telescope has caught the first image of 3I/ATLAS. It is only the third known object from beyond our solar system.
-
Uranus is unlike any other planet in space. It tilts sideways, spinning like a barrel in orbit. Each pole gets 42 years of direct sunlight.
-
This is only the third interstellar object ever found. The first was 'Oumuamua in 2017, and the second, Borisov, in 2019.
-
On April 20, Lucy zoomed past Donaldjohanson at incredible speed. The spacecraft captured a series of close-up images using its L’LORRI imager just before the flyby.
-
It currently sits around 420 million miles (or 670 million kilometres) from Earth. Astronomers have since confirmed its foreign origin—it’s only the third known comet to travel from beyond our solar system.
-
The giant planet, named TOI-6894b, was spotted using NASA’s Transiting Exoplanet Survey Satellite, or TESS.
-
In 2022 and 2023, researchers turned JWST's powerful MIRI instrument toward Pluto. What they found was unlike anything seen elsewhere in the Solar System.
-
The asteroid was spotted during Lucy’s latest close encounter. The spacecraft flew just 960 kilometres above its surface on 20 April.
-
The European Space Agency's SOHO spacecraft was the first to detect it. Its SWAN instrument, which observes solar activity, detected the object.
-
As the solar system moved through this dust-rich region, Earth may have received an increased influx of interstellar particles.
-
Astronomers have discovered 128 new moons orbiting Saturn, giving the ringed planet a total of 274 confirmed moons and surpassing Jupiter's moon count, providing new insights into the solar system's formation and evolution.

Have you ever wondered how our home planet, Earth, looks from other planets in our solar system? Let's take a cosmic journey to explore the breathtaking views of Earth from our celestial neighbors.
-
New research suggests millions of unseen interstellar objects, some as big as the Statue of Liberty, could be trapped in the solar system, originating from Alpha Centauri, our closest star system.
-
NASA's Jet Propulsion Laboratory (JPL) is closely monitoring asteroid 2025 CA2, which is set to pass by Earth on 18 February 2025.
