Annular solar eclipse turns the sun into a dramatic 'ring of fire' today! Here's what you need to know

Today (Feb. 17), the moon and sun will create a "ring of fire" during an annular solar eclipse. Here's what to expect.

Scientists Make a Game-Changing Find in the Bennu Asteroid

In 2023, NASA's OSIRIS-REx mission delivered samples of the 4.6-billion-year-old asteroid Bennu to Earth. Upon examining them, scientists discovered that the asteroid - which existed when the Solar System was in the earliest phase of its formation - contained amino acids, the fundamental building blocks of life as we know it. These acids are responsible for the production of proteins and peptides found in DNA. Their retrieval from space confirmed what scientists had theorized decades ago: that the ingredients for life came from space.

Why don't more Tatooine-like exoplanets exist in our Milky Way galaxy? Astronomers might have an answer

Astronomers may finally understand why planets orbiting two suns, the real-world equivalents of the "Star Wars" planet Tatooine, are so scarce in our galaxy — and it has to do with general relativity.

Astronomers discover chemicals that could seed life in the core of a developing star

An organic molecule called methanimine was found scattered throughout a dense clump of gas and dust 554 light-years away.

Very Few Planets Have the Right Chemistry for Life

Many factors influence a planet's habitability. The more obvious ones include being in a star's habitable zone and having a magnetic shield to protect it from radiation. But other important factors are less obvious.

Comet C/2024 E1 Wierzchos makes its closest approach to Earth tomorrow: Here's what you need to know

The comet is now racing away from the sun following a close flyby on Jan. 20.

Wormholes may not exist – we've found they reveal something deeper about time and the universe

The puzzle Einstein and Rosen were addressing was never about space travel, but about how quantum fields behave in curved spacetime. I

The Moon Hides Mercury, Tours the Planets Through Late February

The Moon paves the way among the planets in the last half of February.

How astronomers are unveiling the 'skeleton' of the universe

Faint structures play a crucial role in cosmic development, and scientists are only just beginning to grasp their full extent and role in shaping the universe.

Double delivery: SpaceX sends Starlink satellites into orbit on launches from California and Florida

SpaceX Falcon 9 rockets carrying Starlink satellites launched on Feb. 14 and Feb. 16, 2026 from Vandenberg Space Force Base, California and Cape Canaveral Space Force Station, Florida, respectively.

Five new Mandalorian-themed sets are coming soon from Lego

With The Mandalorian & Grogu movie release getting ever closer, Lego has just announced five tie-in sets.

Scientists hunt for origins of the mysterious 'sun goddess' particle

Scientists have used a novel new approach to discover the potential origins of the sun goddess particle Amaterasu, the second most energetic cosmic ray ever to be detected striking Earth.

'Fully unlocking the orbital economy': California company will fly astronauts to the space station in 2027

NASA has selected the California startup Vast to operate the sixth private astronaut mission to the International Space Station. Liftoff is targeted for summer 2027.

Is Dark Energy Actually Evolving?

Dark energy is one of those cosmological features that we are still learning about. While we can’t see it directly, we can most famously observe its effects on the universe - primarily how it is causing the expansion of the universe to speed up. But recently, physicists have begun to question even that narrative, pointing to results that show the expansion isn’t happening at the same rate our math would have predicted. In essence, dark energy might be changing over time, and that would have a huge impact on the universe’s expansion and cosmological physics in general. A new paper available in pre-print on arXiv from Dr. Slava Turyshev, who is also famously the most vocal advocate of the Solar Gravitational Lens mission, explores an alternative possibility that our data is actually just messy from inaccuracies in how we measure particular cosmological features - like supernovae.

What time is the annular solar eclipse on Feb. 17?

A 'ring of fire' eclipse is coming to Antarctica on Feb. 17.

How Rotten Eggs Solved an Exoplanet Mystery

Nobody expects hydrogen sulphide to smell pleasant. The molecule responsible for the distinctive odour of rotten eggs hardly suggests breakthrough science. Yet its detection in the atmospheres of four distant gas giants has just answered one of planetary science's most fundamental questions: what makes a planet a planet?

A New Concept for Catching Up with 3I/ATLAS

The arrival of 3I/ATLAS in our Solar System spawned multiple proposals for a rendezvous mission to study it up close. As the third interstellar object (ISO) ever detected, the wealth of information direct studies could provide would be groundbreaking in many respects. However, the mission architecture for intercepting an interstellar comet poses numerous significant challenges for mission designers and planners. Chief among them is the technological readiness level (TRL) of the proposed propulsion systems, ranging from conventional rockets to directed-energy propulsion (DEP).

The Little Moon with a Giant Electromagnetic Punch

At just 500 kilometres across, Saturn's sixth largest moon would fit comfortably inside my home country, the United Kingdom with room to spare. Yet new research reveals this tiny ice world wields electromagnetic influence over distances exceeding half a million kilometres, more than the distance between Earth and the Moon.

Earth's Radiation Fingerprint

Earth's radiation budget, that’s the balance between incoming sunlight and outgoing heat, drives our climate system. Understanding it requires measuring radiation escaping from every corner of our planet, but current satellite observations face a fundamental trade off. Low Earth orbit satellites provide detailed snapshots but miss temporal continuity, whilst geostationary satellites maintain constant watch but can't see the whole globe at once. Time for an unusual solution, enter an unlikely observation platform: the Moon.
