Using NASA’s Hubble Space Telescope, astronomers pinpointed an invisible monster lurking 600 million light-years away, but not in any galactic center, where supermassive black holes are typically found. This sneaky black hole quietly devours stars that wander too close and surrounding material. Its presence was exposed in a recent tidal disruption event (TDE) called AT2024tvd, where a doomed star was shredded and consumed, unleashing a brilliant burst of radiation.

State-space models are AI designed to better understand long-term patterns in data, such as climate trends or biological signals. Unlike traditional models, they track how information evolves rather than just analyzing individual points. However, these models can sometimes become unstable or require high computational power, making them challenging to scale for long sequences. Researchers are improving their efficiency to make them more reliable for analyzing complex, evolving data.

Neutron stars are incredibly dense remnants of exploded stars. When these stars collapse, they often get a powerful kick, sending them speeding through space. The Milky Way’s center contains immense, bone-like structures that appear in radio waves and are lined with parallel magnetic fields. The radio waves come from charged particles spiraling along these fields, creating the mysterious features seen in space.

NASA’s SPHEREx space observatory has officially begun its science operations following its March 11 launch and six weeks of calibrations. This mission is mapping the entire sky in 3D, tracking hundreds of millions of galaxies to investigate the origins of the universe and the building blocks of life in the Milky Way. On May 1, SPHEREx started capturing about 3,600 images daily, with plans to operate for two years.

The Daniel K. Inouye Solar Telescope, the world’s most powerful solar telescope, has reached a key milestone. Operated by the NSF National Solar Observatory (NSO), it has captured its first solar image using its most advanced instrument, the Visible Tunable Filter (VTF)—the largest imaging spectro-polarimeter ever built. A newly released image shows sunspots on the Sun’s surface at 10 km (6.2 miles) per pixel resolution.
