3D-printed ‘hydrogels’ could be future space radiation shields for astronaut trips to Mars
Technology we already use everyday might be the future of space radiation shielding.
James Webb Space Telescope learns how a cosmic phoenix cools off to birth stars
Like its mythological namesake, the Phoenix Cluster burns with blisteringly hot gas, which cools to birth stars. The James Webb Space Telescope has now learned how this galaxy cluster does it.
‘Star Trek: Section 31’ got us thinking… Should you have to do your homework before you watch a movie?

The Winter Triangle meets the ‘Mars Triangle’ in the night sky this month
For the next few weeks, the planet Mars will form an isosceles triangle with the two bright stars marking the heads of the Gemini Twins, Pollux and Castor.
Watch the sun erupt in new images from NOAA’s weather satellite
A space-based telescope has captured new images of the sun that showcase one of our star's fiery outbursts — and Mercury is in the picture.
Some planet-forming stars never ‘grow up’ and lose their ‘Peter Pan’ disks
Astronomers used the James Webb Space Telescope to study a planet-forming disk around a low-mass star, finding it contains chemical signatures never seen before in such a disk.
Astronomers realize mysterious TV signal in their data bounced off an airplane
By tracking the TV signal back to the plane that was reflecting it towards the Murchison Wide-field Array, astronomers will be able to learn how to remove it from their data.
‘City-killer’ asteroid 2024 YR4 could hit the moon instead of us, scientists say
Asteroid 2024 YR4 has a 2.3% chance of hitting Earth in the year 2032. But according to new estimates, it may have an even smaller chance of hitting the moon instead.
Continent-size blobs in Earth’s mantle are a billion years old, ancient crystals reveal
New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion.
