Europe's first deep-space optical communication link
The European Space Agency (ESA) successfully established a transmission-reception optical link with NASA’s Deep Space Optical Communications (DSOC) experiment onboard its Psyche mission, located 265 million kilometres away, using two optical grounds stations developed for this purpose in Greece.

The JWST Shows Us How Galaxies Evolve
The Milky Way and other similar galaxies have two distinct disk sections. One is the thin disk section, and it contains mostly younger stars with higher metallicity. The second is the thick disk, and it contains older stars with lower metallicity. The effort to study these disks in more galaxies and in greater detail has been stymied. But now we have the JWST, and researchers used it to examine more than 100 distant, edge-on galaxies.
When Theia Struck Earth, it Helped Set the Stage for Life to Appear
Earth life is carbon-based, and without carbon, there would be no life. New research shows how Earth got its carbon from impactors, including a boost from Theia, the impactor that created the Moon. Jupiter also pitched in to help.
Primordial Black Holes Could Have Accelerated Early Star Formation
The search for dark matter requires all of the best models, theories, and ideas we can throw at it. A new paper from Julia Monika Koulen, Stefano Profumo, and Nolan Smyth from the University of California at Santa Cruz (UCSC) tackles the implications of the sizes and abundance of one of the more interesting dark matter candidates - primordial black holes (PBHs).
How To Use Fusion To Get To Proxima Centauri's Potentially Habitable Exoplanet
Proxima Centauri b is the closest known exoplanet that could be in the habitable zone of its star. Therefore, it has garnered a lot of attention, including several missions designed to visit it and send back information. Unfortunately, due to technological constraints and the gigantic distances involved, most of those missions only weigh a few grams and require massive solar scales or pushing lasers to get anywhere near their target. But why let modern technological levels limit your imagination when there are so many other options, if still theoretical, options to send a larger mission to our nearest potentially habitable neighbor? That was the thought behind the Master’s Thesis of Amelie Lutz at Virginia Tech - she looked at the possibility of using fusion propulsion systems to send a few hundred kilogram probe to the system, and potentially even orbit it.
