NASA's Roman to peer into cosmic 'lenses' to better define dark matter

Dark matter affects how stars move within galaxies, how galaxies build up over time, and how everything in the universe is held together - but no existing tool has directly detected it. While dark matter does not reflect, absorb, or emit light, it can still be indirectly observed by telescopes.

20-Million-Light-Year-Wide Cloud of Particles around Distant Galaxy Cluster

Astronomers have discovered the largest known cloud of energetic particles surrounding a galaxy cluster - the 20-million-light-year-wide cloud around the galaxy cluster PLCK G287.0+32.9.

Hubble Investigates Surface Conditions on Four Uranian Moons

In new research, astronomers using the NASA/ESA Hubble Space Telescope searched for signs of interactions between the magnetic environment and the surfaces of Uranus and its four largest moons: Ariel, Umbriel, Titania, and Oberon.

The atmosphere is getting thirstier and it's making droughts worse

Rising “atmospheric thirst” – also known as atmospheric evaporative demand (AED) – is responsible for about 40% of the increase in drought severity over the last four decades (1981-2022).

Atmosphere of Saturn's Titan Wobbles Like Gyroscope

Titan is the only moon in the Solar System with a significant atmosphere, and one that has long captivated planetary scientists.

Largest explosions in the universe since the Big Bang

Astronomers in Hawaii detected three different stars being devoured by supermassive black holes that released more energy than 100 supernovas. These are the largest explosions since the Big Bang. 

Asteroid 2024 YR4 chances of hitting the moon go up again

On April 2, 2025, NASA said that new data from the Webb space telescope and ground-based telescopes suggested a 3.8% chance of a moon strike.

Giant planet around tiny star challenges formation theories

An international team of astronomers discovered a giant planet orbiting the smallest known star to host such a companion. It’s a finding that defies current theories of planet formation.

NASA Webb Identifies Frozen Water in Young Star System

Researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star 155 light-years away using detailed data known as spectra from NASA’s James Webb Space Telescope.

A 'Crazy Idea' About Pluto Was Just Confirmed in a Scientific First

When the New Horizons spacecraft swept past Pluto and Charon in 2015, it revealed two amazingly complex worlds and an active atmosphere on Pluto.

What if the Big Bang wasn't the beginning?

In this blog, Professor Enrique Gaztanaga from the Institute of Cosmology and Gravitation at the University of Portsmouth, puts forward a new theory about how the Universe was created.

Origins of ultra-hot exoplanet WASP-121b revealed

Researchers have used new clues from the James Webb Space Telescope (JWST) to provide a fascinating insight into how the exoplanet WASP-121b formed. 

We now have a good idea about the makeup of Uranus' atmosphere

20 years of observations have given us more knowledge about the icy giant.

Uncovering Ongoing Surface Modification On Europa

The JWST shows that ice on Europa is developing at different rates in different places, such as Tara Regio, where crystalline ice (lighter colors) is found on the surface as well as below the surface.

Stunning Images Reveal The Sun's Surface in Unprecedented Detail

A team at the National Solar Observatory is using AO to examine the Sun's corona in unprecedented detail.
