cosmic inflation big bang dark ages
The hot Big Bang was an energetic, brilliantly luminous event. Today's Universe is alight with stars. But in between, the dark ages ruled.
NASA Fermi LAT pulsar gamma ray sky
An enormous amount of antimatter is coming from our galactic center. But the culprit probably isn't dark matter, but merely neutron stars.
galaxy cluster PLCK G165.7+67.0 triply lensed supernova
Named "Supernova H0pe," it shows how JWST plus gravitational lensing can be used to solve the greatest puzzle facing astronomy today.
Nasa's nasa spacecraft observing annular eclipse.
An annular eclipse is coming to Earth on October 14, 2023. Six months later, a total solar eclipse is headed our way. Here's the reason why.
spiral galaxies MIRI PHANGS JWST
How does star-formation, occurring in small regions within galaxies, affect the entire host galaxy that contains it? JWST holds the answers.
hypermassive neutron star
Neutrons can be stable when bound into an atomic nucleus, but free neutrons decay away in mere minutes. So how are neutron stars stable?
quantum gravity
Dark matter hasn't been directly detected, but some form of invisible matter is clearly gravitating. Could the graviton hold the answer?
