A Whisper of Radio Waves Pins Down the Distance to a Mysterious Gamma-Ray Halo
China's FAST telescope caught a microjansky-faint radio pulse from a gamma-ray pulsar, finally giving astronomers a distance estimate that helps explain the puzzling TeV source it may be powering.

Webb Catches Baby Stars Feeding in Fits and Starts: New Evidence for Episodic Accretion in FS Tau
A new Webb infrared image of the FS Tau protostar system reveals gaps in its gas outflows — evidence that young stars gain mass in sudden bursts rather than a steady stream.

X-ray Echoes of Dead Stars Nudge the Milky Way's Outer Arms Farther Out
Using dust-scattered X-ray light echoes from three gamma-ray bursts, astronomers re-measured two of the Milky Way's outer spiral arms and found them up to 10% farther from the galactic center than assumed.

Hubble's 'Chandelier Cluster' Reveals Its Ancient Stars Formed in Two Separate Bursts
Hubble's June 2026 image of NGC 6723, the 'Chandelier Cluster,' shows its 10-billion-year-old stars formed in two closely spaced bursts — the second within 634 million years of the first — undercutting the old idea that globular clusters are single-age populations.

Euclid's 60-Million-Star Portrait of the Galactic Bulge Lays Groundwork for Roman
Euclid's new visible-light mosaic of the Milky Way's crowded center packs 60 million stars across 22 Moons of sky — and quietly hands NASA's Roman telescope a two-year head start on its planet hunt.
