Do Neutron Stars Have Mountains? Gravitational Wave Observatories Could Detect Them
Neutron stars are the incredibly dense remnants from massive star supernovae. Although they're pulled into dense spheres by their intense gravity, it's believed that neutron stars could have slight deformations, known as "mountains," caused by crustal strains and interactions with magnetic fields. If the mountains are there, merging neutron stars should slightly distort the signal received by gravitational wave observatories.

Want to Find Life? See What's Missing in an Atmosphere
In the search for life, astrobiologists have proposed that various chemicals, like methane, could be potential biosignatures. But a new study suggests that missing chemicals might make an even stronger case there's life in the world. For example, if a terrestrial planet has much less carbon dioxide in its atmosphere than other planets in the same system, life could cause the difference. Fortunately, this is the kind of signal JWST could search for.

The Most Massive Neutron Stars Probably Have Cores of Quark Matter
When a star with several times the mass of the Sun dies in a supernova explosion, it ends up as a neutron star, compressing its protons and electrons into neutrons. But neutron stars have layers, and the most massive ones there might have a core made of an even denser material called "deconfined quark matter." A new supercomputer simulation predicts that the most massive neutron stars almost certainly have these quark-matter cores.

The Early Universe Was Surprisingly Filled With Spiral Galaxies
The Milky Way is a mature, grand spiral galaxy, and so are many galaxies around us. Astronomers have assumed that spiral galaxies are the result of many mergers between dwarf galaxies and shouldn't show up until later on in the Universe's evolution. New research using JWST has shown that's not true, with a surprising number of spiral galaxies in the first few billions years of the Universe's history. Spiral arms showed up much earlier than anyone expected.

The Atmosphere of an Exoplanet Reveals Secrets About Its Surface
Astronomers have now characterized the atmospheres of several exoplanets, with JWST and upcoming missions promising to turn that into the thousands. The next era will come when our observatories can directly observe the surfaces of exoplanets. We're learning that the atmospheres of planets and their surfaces affect one another, and just by observing their atmospheres, we'll learn valuable secrets about the surfaces of those worlds.
