Astronomers discover over 800 cosmic anomalies using a new AI tool

Engadget

Other discoveries included planet-forming disks viewed edge-on, galaxies with huge clumps of stars and jellyfish galaxies . Adding a bit of mystery, there were even several dozen objects that defied classification altogether. This is a fantastic use of AI to maximize the scientific output of the Hubble archive, Gómez is quoted as saying in the ESA's announcement. Finding so many anomalous objects in Hubble data, where you might expect many to have already been found, is a great result. It also shows how useful this tool will be for other large datasets.

The Chandra X-Ray Observatory has gathered over 1.3 million detections in 27 years. Breakthroughs, discoveries, and DIY tips sent six days a week. NASA's Chandra X-Ray Observatory is considered one of the agency's greatest achievements, but it's not necessarily as recognizable as siblings like the James Webb and Hubble Space Telescopes . However, since 1999, the powerful spacecraft has peered deep into the cosmos to provide astronomers with never-before-seen glimpses of the Milky Way galaxy . As the observatory nears its 27th anniversary, NASA is highlighting its Chandra Source Catalog (CSC), an absolutely massive archive of visualization data collected over the years.

Mysterious space object is full of dark matter

Popular Science

The failed star factory is nicknamed'Cloud-9.' This image shows the location of Cloud-9, which is 2000 light-years from Earth. The diffuse magenta is radio data from the ground-based Very Large Array (VLA) showing the presence of the cloud. The dashed circle marks the peak of radio emission, which is where researchers focused their search for stars. Breakthroughs, discoveries, and DIY tips sent every weekday.

'We essentially have 102 new maps of the entire sky.' Breakthroughs, discoveries, and DIY tips sent every weekday. NASA aimed big for its SPHEREx's first 3D cosmic map . Only six months after starting operations, the orbital space telescope has completed its inaugural infrared scan of the entire sky. Although infrared isn't visible to the human eye, the map's 102 wavelengths remain detectable across the universe--to the right instruments. "It's incredible how much information SPHEREx has collected in just six months--information that will be especially valuable when used alongside our other missions' data to better understand our universe," Shawn Domagal-Goldman, director of the Astrophysics Division at NASA, said in a statement .

IAEmu: Learning Galaxy Intrinsic Alignment Correlations

Pandya, Sneh, Yang, Yuanyuan, Van Alfen, Nicholas, Blazek, Jonathan, Walters, Robin

arXiv.org Artificial Intelligence

The intrinsic alignments (IA) of galaxies, a key contaminant in weak lensing analyses, arise from correlations in galaxy shapes driven by tidal interactions and galaxy formation processes. Accurate IA modeling is essential for robust cosmological inference, but current approaches rely on perturbative methods that break down on nonlinear scales or on expensive simulations. We introduce IAEmu, a neural network-based emulator that predicts the galaxy position-position ($ξ$), position-orientation ($ω$), and orientation-orientation ($η$) correlation functions and their uncertainties using mock catalogs based on the halo occupation distribution (HOD) framework. Compared to simulations, IAEmu achieves ~3% average error for $ξ$ and ~5% for $ω$, while capturing the stochasticity of $η$ without overfitting. The emulator provides both aleatoric and epistemic uncertainties, helping identify regions where predictions may be less reliable. We also demonstrate generalization to non-HOD alignment signals by fitting to IllustrisTNG hydrodynamical simulation data. As a fully differentiable neural network, IAEmu enables $\sim$10,000$\times$ speed-ups in mapping HOD parameters to correlation functions on GPUs, compared to CPU-based simulations. This acceleration facilitates inverse modeling via gradient-based sampling, making IAEmu a powerful surrogate model for galaxy bias and IA studies with direct applications to Stage IV weak lensing surveys.
