By observing the young star HW2 in Cepheus A, located 2300 light years from Earth, researchers have resolved the structure and dynamics of an accretion disk feeding material to this massive star. This finding sheds light on a central question in astrophysics: how do massive stars, which often end their lives as supernovae, accumulate their immense mass?

NSF VLA Contributes Crucial Puzzle Piece to ‘Peculiar’ High Energy Transient
January 27, 2025 at 9:00 am | News Release

High-energy transient signals are most often determined to be gamma-ray burst events, but the recently-launched Einstein Probe has expanded astronomers’ ability to quickly respond to similar signals occurring at X-ray wavelengths.

Helical Magnetic Fields: A Universal Mechanism for Jet Collimation?
Helical Magnetic Fields: A Universal Mechanism for Jet Collimation?
January 7, 2025 at 12:53 pm | News Release

New observations from the National Science Foundation National Radio Astronomy Observatory’s (NSF NRAO) Karl G. Jansky Very Large Array (NSF VLA) provide compelling evidence supporting a universal mechanism for the collimation of astrophysical jets, regardless of their origin. A new study, published in the Astrophysical Journal Letters, reveals the presence of a helical magnetic field within the HH 80-81 protostellar jet, a finding that mirrors similar structures observed in jets emanating from supermassive black holes.

Astronomers Detect Earliest and Most Distant Blazar in the Universe
Astronomers Detect Earliest and Most Distant Blazar in the Universe
December 18, 2024 at 11:00 am | News Release

A groundbreaking discovery has revealed the presence of a blazar—a supermassive black hole with a jet pointed directly at Earth—at an extraordinary redshift of 7.0. The object, designated VLASS J041009.05−013919.88 (J0410−0139), is the most distant blazar ever identified, providing a rare glimpse into the epoch of reionization when the universe was less than 800 million years old. This discovery challenges existing models of black hole and galaxy formation in the early cosmos.
