Back in 2009, astronomers using the Fermi Gamma-ray Space Telescope noticed that there was a lot more gamma-ray light coming from the center of the Milky Way than might otherwise be expected given the objects there. Since then, two theories have appeared to explain this Galactic Center Excess (GCE) as it’s become known. One theory posits that the extra gamma rays are created by thousands of unseen milli-second pulsars (MSPs) in the Galactic center, while the other suggests that dark matter annihilating itself could also be the source. A new paper from Moortis Muru and hisco-authors at the Leibniz Institute for Astrophysics Potsdam (AIP) hasn’t necessarily solved the conundrum, but does level the playing field between the two theories again.

Lake Turkana in Kenya, known as the cradle of humanity, has shrunk in recent millennia – and the loss of water has led to increased seismic activity, which could have impacted our ancient ancestors

Several large tech firms that are active in AI have set goals to hit net zero by 2030, but a new forecast of the energy and water required to run large data centres shows they’re unlikely to meet those targets

The popularization of the term “slop” for AI output follows a centuries-long pattern where new tools flood the zone, audiences adapt and some of tomorrow’s art emerges from today’s excess

An international team of researchers, led by the Leibniz Institute for Astrophysics Potsdam (AIP), has shed light on a decades-long debate about why galaxies rotate faster than expected, and whether this behaviour is caused by unseen dark matter or a breakdown of gravity on cosmic scales.

The ESA's ExoMars Trace Gas Orbiter (TGO) recently captured images of streaks formed from a dust avalanche on the slopes of Apollinaris Mons the night before Christmas in 2023. A new study reveals that these types streaks are largely the result of seasonal factors, rather than meteoroid impacts.

It’s almost become expected that many space telescopes and probes can have “extended missions”. Both Voyagers are still sending data back 40+ years after their 5-year primary mission ended. But figuring out what to do with those spacecraft after their primary mission takes some negotiation. One such craft that will reach its end-of-mission in 2030 is Euclid, which is currently on a mission to map the “dark universe” of dark energy and dark matter. According to a new paper from Luigi “Rolly” Bedin of the Astronomical Institute of Padova, which is available in pre-print form on arXiv, for its second act we could turn Euclid into the most powerful astrometric telescope ever made.
