The Keen-Eyed Vera Rubin Observatory Has Discovered a Massive Stellar Stream
The Vera Rubin Observatory’s first light images captured the Virgo Cluster of galaxies, highlighting the discovery of a massive 163,000-light-year-long stellar stream extending from the spiral galaxy Messier 61. This stream is likely the remnant of a dwarf galaxy or globular cluster torn apart by tidal forces.
Rapid Brightening of Interstellar Comet 3I/ATLAS As It Nears Sun Surprises Scientists
An interstellar comet named 3I/ATLAS, only the third of its kind recorded, recently passed close to the sun, brightening at an unprecedented rate and appearing blue instead of the usual red. This unusual behavior has puzzled scientists, who monitored it using space-based solar observatories due to solar glare blocking Earth-based views. Researchers suggest the brightness surge may be caused by visible gas emissions as the comet neared perihelion.
