Alien Probes Could Be Hiding In Solar System Beyond Our Sight, NASA Study Suggests

A NASA‑linked study argues that alien probes could already be in our Solar System, but our surveys are still too crude to rule them out. From misidentified rocket boosters to blurry moon maps, it suggests we have barely begun to look for extraterrestrial artefacts.

Comet crash or ice volcano? Scientists are stumped by a secret world past Pluto, and it may be wearing a secret atmosphere

2002 XV93 atmosphere mystery stuns space scientists as a distant Kuiper Belt object reveals unexpected signs of activity. The 470-kilometer icy world challenges old Solar System theories. Researchers believe possible gas, dust, impacts, or icy volcanoes may explain this rare cosmic discovery. The finding shows even small worlds can hold…

Sonic booms from meteors can release the energy of hundreds of tons of TNT – here’s how they work

As humans, we live out our lives on a planet that is constantly sweeping through a cosmic ocean littered with ancient debris from the formation of the solar system. For the most part, our world glides silently through space, shielded by Earth’s thin atmosphere.

An ancient piece of the moon found in Africa hints at a long-ago collision that turned the lunar surface molten

A meteorite shows evidence that an ancient crash on the moon 3.5 billion years ago was so powerful, it turned the surface molten.

In 1995, astronomers found a planet circling a Sun-like star, and the solar system stopped looking unique

In 1995, scientists made a revolutionary find with the discovery of 51 Pegasi b, a massive exoplanet in a tight orbit around its star. This startling revelation contradicted prior assumptions about how planets form, opening our eyes to the possibility of planetary systems that aren't structured like our own.

2 long-vanished 'super Earths' once orbited near Neptune in our outer solar system, new study hints

Our solar system may have hosted up to six giant planets in its first hundred million years, a new study suggests. The findings paint a more crowded picture of the early outer solar system than previously thought.

What is Planet Nine, and where is it? Mystery of large hidden planet beyond Neptune explained

What is Planet Nine, and where is it? The question has fascinated astronomers for years. Scientists believe a massive undiscovered planet may exist in the outer Solar System. Although no telescope has directly observed it, unusual movements of Kuiper Belt objects, Extreme Trans-Neptunian Objects, sednoids, and other distant bodies continue…

Why do Venus and Jupiter meet up in the sky so often? It's a symptom of a solar system that supports life on Earth

As it turns out, the conditions that set Venus and Jupiter up for their conjunctions in the sky are the same that are critical for life to survive on Earth.

Upcoming telescopes could shed light on dark matter – astronomers are looking for these ‘fingerprints’ of the elusive substance

NASA’s plans to return astronauts to the Moon through the Artemis program and ultimately send humans to Mars highlight just how far space exploration has come. Yet while the Moon and Mars remain compelling destinations filled with scientific mysteries, looking beyond our solar system raises even deeper questions about the…

Interstellar comet 3I/ATLAS is blasting out a bunch of methane. Here's why that's weird

The James Webb Space Telescope observed a large amount of methane around 3I/ATLAS, revealing just how different it is from comets from our solar system.

Scientists search for signs of alien life on a visitor from another solar system

3I/ATLAS is the third known interstellar object – leading to suggestions that it could be an alien spacecraft

The Independent UK

If 3I/ATLAS isn’t an alien probe, why is it silent on radio signals but rich in methane from another star system?

If 3I/ATLAS isn’t an alien probe, its discovery may be even more important. Scientists detected no radio signals from the interstellar comet despite an extensive search for technosignatures. Instead, the James Webb Space Telescope found unusually high methane and carbon dioxide levels. Those findings suggest 3I/ATLAS formed in a vastly…

'Hot Jupiter' winds blasting at over 15,000 mph reveal 1st evidence of exoplanets with magnetic fields

Astronomers have discovered the first evidence of magnetic worlds beyond the solar system thanks to their high-speed, violent winds, representing a major step forward in exoplanet research.

Scientists used a method from ecology to identify whether icy moons could hold conditions for life

New observatories and spacecraft missions are probing environments in our solar system that could potentially host life but have long remained hidden. Icy moons like Saturn’s Enceladus and Jupiter’s Europa likely contain oceans beneath frozen outer shells. But a layer of ice prohibits space probes from sampling them directly.

A 'lost planet' may have given Jupiter and Uranus their moons

New research suggests the moons of Jupiter and Uranus may hint that our planetary neighborhood once had a third ice giant.
