James Webb Space Telescope makes 1st discovery of disappearing neon around newborn star
Missing neon in a planet-forming disk of gas and dust indicates a change in radiation that's slowly eroding the disk.
1 year after Artemis 1 launch, NASA readies Artemis 2 to shoot for the moon again (video)
Artemis 1 launched on Nov. 16, 2022. One year later, NASA is readying the follow-up Artemis 2 mission to send four astronauts around the moon.
The Echoes From Inflation Could Still Be Shaking the Cosmos Today
In the very early universe, physics was weird. A process known as “inflation,” where best we understand the universe went from a single infinitesimal point to everything we see today, was one such instance of that weird physics. Now, scientists from the Chinese Academy of Science have sifted through 15 years of pulsar timing data in order to put some constraints on what that physics looks like.

Hubble measures the size of the nearest transiting Earth-sized planet
The NASA/ESA Hubble Space Telescope has measured the size of the nearest Earth-sized exoplanet that passes across the face of a neighbouring star. This alignment, called a transit, opens the door to follow-on studies to see what kind of atmosphere, if any, the rocky world might have.
How students built Ireland’s first satellite
Video: 00:22:10
A team of university students from University College Dublin is taking Ireland to space, for the very first time. The story begins in 2017, when the team was accepted to ESA's educational CubeSat programme, Fly Your Satellite! Over the course of six years, they have designed, built, and tested the satellite with the help of ESA experts and with access to ESA's state-of-the-art spacecraft testing facilities. As the team prepares for launch and operations, hear more about their journey to this historic moment.
