πͺ In the spiral galaxy NGC 3147, astronomers have discovered a supermassive black hole encircled by a disk of gas that defies expectationsβit's thin and spinning at nearly the speed predicted for much larger, brighter disks found around actively feeding black holes. This surprising find, made with the Hubble Space Telescope, shows that even "starving" black holes can maintain disks behaving like those from the most powerful galactic cores, challenging what scientists thought they knew about black hole feeding habits. β¨

πͺ In the galaxy ESO 184-G82, astronomers observed GRB 980425βa gamma-ray burst that was directly linked to a supernova explosion called SN 1998bw. Gamma-ray bursts are intense flashes of the highest-energy light in the universe, and the connection in ESO 184-G82 revealed that some of these powerful bursts are caused when massive stars end their lives in energetic supernovae, giving scientists a rare glimpse into how the most violent stellar deaths can unleash extraordinary cosmic fireworks. β¨

πͺ On Mercury, time passes at a different rate than on Earth because the planet orbits much closer to the Sun and feels stronger gravityβa real effect called time dilation. According to Einstein's theory of relativity, stronger gravity slows down the flow of time, so a clock sitting on Mercury's surface would actually run slightly slower than an identical clock on Earth, making time itself stretch differently across the solar system. β¨
