Magnetic Field Saves Pillars of Creation from Destruction
New 850 micrometer observations, taken as part of the BISTRO (B-Fields in Star-forming Region Observations) Survey using the POL-2 polarimeter on the SCUBA-2 camera of the James Clerk Maxwell Telescope (JCMT) show that the internal magnetic fields run along the length of the pillar.

Double or Nothing: Astronomers Rethink Quasar Environment
Using Hyper Suprime-Cam (HSC) mounted on the Subaru Telescope, astronomers have identified nearly 200 “protoclusters,”the progenitors of galaxy clusters, in the early Universe, about 12 billion years ago.

No relation between a supermassive black hole and its host galaxy!?—The co-evolution mystery deepened by a new ALMA observation
Astronomers observed an active galactic nucleus with ALMA and found that molecular gas in the galaxy is not affected by the ionized gas ejected from the nucleus. This result questions a popular scenario that supermassive black holes and their host galaxies co-evolve by affecting each other.
