Multi-messenger astronomy has been all the rage lately. It involves capturing data on the gravitational and electromagnetic signals from catastrophic cosmic events. However, with that newfound interest comes required updates to infrastructure. Gravitational wave detectors have been upgraded and will be even more sensitive soon. But to realize the promise of multi-messenger astronomy, scientists must have a fleet of spacecraft watching the entire sky for high-energy signals indicative of the events that cause gravitational waves. At least, that is the team's long-term plan behind the High Energy Rapid Modular Ensemble of Satellites Pathfinder (HERMES-PF) mission, which successfully launched in March and is currently undergoing commissioning.

The Solar System is a whopping 26,000 light-years from the heart of the Milky Way, where a mysterious and dense region—shrouded in thick gas and dust—holds one of the Galaxy’s most active zones: the Central Molecular Zone (CMZ). A team of scientists have unleashed a cutting-edge 3D model of this region, mapping out everything from massive molecular clouds to young stars in the making. Armed with powerful radio telescopes and infrared observatories, they’ve pieced together a detailed map, offering a rare glimpse into the heart of our Galaxy’s chaotic core.

Galaxies are stellar factories generating stars at different speeds—some working at a breakneck pace while others trickling along! We have known for a long time that the availability of raw materials makes a difference to stellar formation, but according to a new paper which surveyed 1,000 galaxies the location of the matter plays a role too. Those with a high stellar formation rate seem to have a high volume of gas reserves in the heart of their densest star clusters with the highest concentration of stars.

We know that planets form in protoplanetary disks, swirling collections of gas and dust that rotate around very young stars. But we don't know all the details, partly because it's difficult to see inside these disks and watch the process unfold. One question astronomers want an answer to concerns ultraviolet radiation. Does extreme ultraviolet radiation disrupt the planet-forming process?

Co-paired stars, or stars that travel together, can provide insights into processes that other stars can't. Differences in their brightness, orbits, and chemical composition can hint at different features, and scientists are beginning to exploit them. A new paper from researchers in Australia, China, the US, and Europe analyzed data to determine if one of those features - specifically the depletion of particular elements in a star - could be a sign that it has formed a planet, or if it ate one.

Some 13,000 years ago, the Sun emitted a huge belch of radiation that bombarded Earth and left its imprint in ancient tree rings. That solar storm was the most powerful one ever recorded. The next strongest was the 1839 Carrington Event. It was spurred by a huge solar flare that triggered a powerful geomagnetic storm at Earth. The resulting "space weather" disrupted telegraph communications around the world. Today, as we move through this year's "solar maximum", a period of solar activity that occurs every 11 years, scientists want to prepare governments for the effects of severe solar storms.

The JWST has done it again. The powerful space telescope has already revealed the presence of bright galaxies only several hundred million years after the Big Bang. Now, it's sensed light from a galaxy only 280 million years after the Big Bang, the most distant galaxy ever detected.

Mars' oceans, lakes, and rivers are long gone. They've left behind evidence of their time here in river channels, deltas, paleolakes, and other features. The water's existence isn't a mystery, but its whereabouts is. Did it disappear into space, or did it retreat into underground aquifers?

As humanity heads back to the Moon, a silent danger lurks: exhaust plumes from multiple spacecraft will blast lunar dust into orbit, creating a potentially deadly obstacle course for future missions. The solution will be to build landing pads on the lunar surface out of the lunar regolith. Researchers simulated landing pads just like these and their tests showed they could handle the heat and force of the propellant exhaust from a landing spacecraft. The techniques they found will minimise erosion over multiple landings.

Jupiter and its powerful gravity have played a major role in sculpting the Solar System. A new study provides a glimpse into Jupiter's primordial state, which could have implications for our understanding of how the Solar System evolved.
