It’s a Star-Eat-Planet Universe Out There
Artist's impression of a terrestrial planet being captured by a twin star. Credit: intouchable, OPENVERSE Data, at the end of the day, is our first and last source of understanding. We look, build models to match what we see, predict things we haven’t seen yet, and...
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...

100 Million Computer Hours in One Model Universe
Part of the simulated universe. Credit: The AGORA Collaboration In a paper that made me do math, researchers have shared the results of a remarkable new suite of simulations that explore how galaxies are born, live, and evolve. Over 160 researchers from 60...
Closer Look: Diversity Makes Understanding More Difficult (Planetary Edition)
Planet-forming discs around young stars and their location within the gas-rich cloud of Orion, roughly 1600 light-years from Earth. The mesmerising images of the discs were captured using the Spectro-Polarimetric High-contrast Exoplanet REsearch (SPHERE) instrument...
Galactic Death may not be Permanent
False-colour JWST image of a small fraction of the GOODS South field, with JADES-GS-z7-01-QU highlighted. Credit: JADES Collaboration In a paper in Nature, with Tobias Looser as the first author, researchers discuss a galaxy cataloged as JADES-GS-z7-01-QU. This...
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...

Can Radar Protect Us From the Earth-Killer?
Deep Space Station 13 at NASA’s Goldstone complex in California – part of the agency’s Deep Space Network – is an experimental antenna that has been retrofitted with an optical terminal. In a first, this proof of concept received both radio frequency and laser signals...
