'We thought it was impossible:' Water frost on Mars discovered near Red Planet's equator
Water frost has been found on huge volcanoes at the equator of Mars, a region where scientists thought frost was impossible.
Frosty volcanoes discovered in Mars’s tropics
ESA’s ExoMars and Mars Express missions have spotted water frost for the first time near Mars’s equator, a part of the planet where it was thought impossible for frost to exist.
A milestone in digital Earth modelling
Destination Earth is now live! Launched today during a ceremony at the EuroHPC LUMI Supercomputer Centre in Kajaani, Finland, Destination Earth provides unprecedented insights into the complexity of our planet to advance climate change adaption and environmental resilience modelling.
Youthful galaxy in the early universe was a heavy metal rebel
The existence of carbon in the early universe means that planets and perhaps even life could have formed sooner than anticipated.
The Milky Way's last major act of galactic cannibalism was surprisingly recent
Gaia discovers the Milky Way's last major act of galactic cannibalism was surprisingly recent, as the space telescope counts the "wrinkles" of our galaxy to retell its history."
'Supercharged rhino' black holes may have formed and died a second after the Big Bang
Tiny 'supercharged' black holes born just after the Big Bang may have been brief companions to primordial black holes, dying before the universe was a second old.
Starlink Flares Can Fool Anyone — Even Airline Pilots
Starlink satellites can flare as brightly as Venus, confusing ground observers and airline pilots alike.

Teaming up for space fun
PLAYMOBIL's little robot space explorer ROBert was reunited with ESA astronaut Matthias Maurer and ESA Kids mascot Paxi as they teamed up to meet young space fans at ESA's Space Days. Children had an absolute blast at ESA's Space Days, held at the PLAYMOBIL FunPark in Zirndorf, Germany from 30 May to 2 June 2024.
Instead of Losing its Atmosphere, an Exoplanet Puffed Up and Held Onto it
To date, astronomers have confirmed the existence of 5638 extrasolar planets in 4,199 star systems. In the process, scientists have found many worlds that have defied expectations. This is certainly the case regarding “hot Neptunes,” planets that are similar to the “ice giants” of the outer Solar System but orbit much closer to their stars. But when a Johns Hopkins University-led team of astronomers discovered TIC365102760 b (aka. Pheonix), they observed something entirely unexpected: a Neptune-sized planet that retained its atmosphere by puffing up.
Carbon is Surprisingly Abundant in an Early Galaxy
The James Webb Space Telescope (JWST) has once again found evidence that the early universe was a far more complex place than we thought. This time, it has detected the signature of carbon atoms present in a galaxy that formed just 350 million years after the Big Bang – one of the earliest galaxies ever observed.

What is the 3-body problem, and is it really unsolvable?
The three-body problem is a physics conundrum that has boggled scientists since Isaac Newton's day. But what is it, why is it so hard to solve and is the sci-fi series of the same name really possible?

Two astronauts performed tests inside full-scale mock ups of SpaceX’s Starship Human Landing System to test spacesuits and other hardware for NASA's Artemis 3 moon mission.
'Stellar Dreams' project gifting 100 telescopes to 100 families (exclusive)
An interview with Raven Baxter and NASA's Ronald Gamble about the Stellar Dreams Project, which will give 100 telescopes to 100 families.
Euclid is Finding Free Floating Planets in Orion Too
There are likely millions of “rogue” or free-floating planets (FFPs) spread through the galaxy. These planets, which aren’t big enough to become stars but also aren’t beholden to a star’s gravity, are some of the hardest objects for astronomers to spot, as they don’t give off their own light, and can only be seen when they cross in front of something that does give off its own light. Enter Euclid, a space telescope that launched last year. Its primary mission is to observe the universe’s history, but a new paper describes an exciting side project – finding FFPs in Orion.
