• Would You See the Future While Falling Into a Black Hole? — Relativity makes clocks disagree near a black hole, but the popular claim that a falling observer sees the entire future needs careful limits.
• How does Parker read the Sun's corona? — Direct data collected by a spacecraft from inside the star's atmosphere.
• How Webb sees the first galaxies — The cosmological redshift moves light from the early universe into the infrared.
• Tracing the cosmic dust: galaxies appearing in a row — NASA's Overlap Zoo call turns galaxy pairs into an observing tool for cosmic dust.
• Webb's panorama of IC 348: a new look at star birth — We examine young stars, brown dwarfs and the limits of observation through the observation of September 15, 2026.
• Chandra's mysterious X-ray sources — 84 extraordinary sources, stellar remnants and unseen energy in galaxies.
• James Webb examines planet-shattering collisions — How silica in extreme debris disks reveals violent pasts of young planetary systems
