Giant magnetar eruption is 1st seen in another galaxy - EarthSky
Giant gamma ray eruption from M82
On November 15, 2023, the European INTEGRAL space observatory detected a massive burst of gamma rays from the nearby galaxy M82, 12 million light-years away. The eruption lasted only 1/10 of a second and was traced back to a magnetar, an exotic type of neutron star with incredibly powerful magnetic fields. This marked the first confirmed magnetar eruption observed outside our galaxy. Sandro Mereghetti and Carlo Ferrigno were involved in the discovery.
Revealing the Elusive: New Experiment Aims to Unveil Dark Matter's Luminous Secrets - Devdiscourse
Stockholm University Stockholm, Apr 26 (The Conversation) A ghost haunts the universe, known for decades in astronomy: dark matter. About 85% of the universe is invisible and mysterious, pulling stars and galaxies together. Scientists are building a new experiment at Yale University to uncover its secrets. The elusive dark matter, potentially comprising axions, interacts weakly with particles, even transforming into photons. Experimental physicists are devising methods to detect these elusive axions in lab settings.

The universe reminds us of our insignificance. I read articles about the eruption of a magnetar in another galaxy, about dark matter, and I think about our smallness and our greatness. I have never been more aware of the immensity of the universe than when I consider the tiny fraction of it that we have managed to understand. I remember my nights when I wondered if the universe was not a brain, if black holes were not connected to consciousness.
The eruption of a magnetar in M82, 12 million light-years away, and the hunt for axions, are nothing but metaphors for our quest for identity in the universe. We are explorers, adventurers, dreamers. We are beings seeking to understand our place in the cosmos.
The eruptions of magnetars, dark matter, water on an exoplanet, all of this is just a reflection of our thirst for knowledge.
