ESA's JUICE Mission Reveals More Activity from 3I/ATLAS

During November 2025, ESA’s Jupiter Icy Moons Explorer (JUICE) used five of its science instruments to observe 3I/ATLAS. The instruments collected information about how the comet is behaving and what it is made of.



Engineering the First Reusable Launchpads on the Moon

Engineers need good data to build lasting things. Even the designers of the Great Pyramids knew the limestone they used to build these massive structures would be steady when stacked on top of one another, even if they didn’t have tables of the compressive strength of those stones. But when attempting to build structures on other worlds, such as the Moon, engineers don’t yet know much about the local materials. Still, due to the costs of getting large amounts of materials off of Earth, they will need to learn to use those materials even for critical applications like a landing pad to support the landing / ascent of massive rockets used in re-supply operations. A new paper published in Acta Astronautica from Shirley Dyke and her team at Purdue University describes how to build a lunar landing pad with just a minimal amount of prior knowledge of the material properties of the regolith used to build it.

Astronomers Find the First Compelling Evidence of "Monster Stars" in the Early Universe

Using the James Webb Space Telescope, a team of international researchers has discovered chemical fingerprints of gigantic primordial stars that were among the first to form after the Big Bang.

During the deployment of new space telescopes that are several critical steps each has to go through. Launch is probably the one most commonly thought of, another is “first light” of all of the instruments on the telescope. Ultimately, they’re responsible for the data the telescope is intended to collect - if they don’t work properly then the mission itself it a failure. Luckily, the Interstellar Mapping and Acceleration Probe (IMAP) recently collected first light on its 10 primary instruments, and everything seems to be in working order, according to a press release from the Southwest Research Institute who was responsible for ensuring the delivery of all 10 instruments went off without a hitch.

The Hubble Witnesses Catastrophic Collisions In The Fomalhaut System

This composite Hubble Space Telescope image shows the debris ring and dust clouds cs1 and cs2 around the star Fomalhaut. Fomalhaut itself is masked out to allow the fainter features to be seen. Its location is marked by the white star. Image Credit: NASA, ESA, Paul Kalas (UC Berkeley); Image Processing: Joseph DePasquale (STScI)

For the first time, astronomers using the Hubble Space Telescope have spotted a pair of catastrophic collisions in another solar system. They were observing Fomalhaut, a bright star about 25 light-years away, and detected a pair of planetesimal collisions and their light-reflecting dust clouds. The system is young, and the collisions reflect what our Solar System was like when it was young.

Could Advanced Civilizations Communicate like Fireflies

In a new paper, a team of researchers explores how non-human species (in this case, fireflies) could inform new approaches in the Search for Extraterrestrial Intelligence (SETI).



Did Astronomers Just Find a ‘Superkilonova’ Double Explosion? Maybe.

Astronomers may have just seen the first ever ‘superkilonova,’ a combination of a supernova and a kilonova. These are two very different kinds of stellar explosions, and if this discovery stands, it could change the way scientists understand stellar birth and death.
