Researchers are learning that the jets associated with black holes can do more than we ever expected to destroy their surroundings. New data from the Atacama Large Millimeter Array and the Very Large Telescope have captured two galaxies in the process of colliding and merging into one system. Like two balls flying past one another on a bowl made of gravity, these two systems will pass back and forth...

JWST Echoes the Hubble Tension

Comparison of Hubble and Webb views of a Cepheid variable star. Credit: NASA, ESA, CSA, STScI, A. Riess (JHU/STScI) Understanding our universe isn’t a straightforward process. For every theory that appears to be beautifully proven out by data, there is another theory...

Gaia Watches the Universe Form

Credit: ESA/Gaia/DPAC; Lucy Reading-Ikkanda/Simons Foundation; K. Storey-Fisher et al. 2024 In trying to understand our universe, theorists can build models that describe how the universe formed as a mostly, but not completely, smooth distribution of matter and energy...

Galaxies are Born Bright

This image from Webb’s NIRCam (Near-Infrared Camera) instrument shows a portion of the GOODS-North field of galaxies. At the lower right, a pullout highlights the galaxy GN-z11, which is seen at a time just 430 million years after the Big Bang. One prominent...

Black Holes Formed Before Stars

An illustration of a magnetic field generated by a supermassive black hole in the early universe, showing turbulent plasma outflows that help turn nearby gas clouds into stars. New findings suggest this process might be responsible for accelerated star formation in...
