Nobel Laureate Anthony Leggett Passes Away at 87
Anthony J. Leggett died at age 87 in Urbana, Illinois. He was awarded the 2003 Nobel Prize for his theories that explained the superfluid transition of helium‑3, a breakthrough that reshaped low‑temperature physics. His work bridged experimental anomalies and introduced a new quantum state of matter.

NASA Discovers Crash of Extreme Stars in Unexpected Site
NASA's Chandra X‑ray Observatory has identified a rare collision of two neutron stars in a region of space previously thought too sparse for such events. The merger, detected through a burst of high‑energy X‑rays and a subsequent kilonova, occurred far from the host galaxy's core, challenging existing astrophysical models. Researchers estimate the combined mass at about 2.8 solar masses and have already coordinated follow‑up observations with gravitational‑wave detectors. The discovery was announced in a press release on March 10, 2026.
