Spectacular advances in modern astronomy have opened our horizon to an unexpected cosmos: a dark, mysterious universe, populated by enigmatic entities we know very little about, such as black holes, d...
The current rate of the expansion of space – called the Hubble constant is a measure of the age and size of the universe. But recently, a new debate has emerged about the Hubble constant, potentiall...
Scanning the first images of a well-known early galaxy taken by NASA’s James Webb Space Telescope (JWST), Cornell astronomers were intrigued to see a blob of light near its outer edge.
When we look out into space, all of the astrophysical objects that we see are embedded in magnetic fields. This is true not only in the neighborhood of stars and planets, but also in the deep space be...
It all started around 13.8 billion years ago with a big, cosmological “bang” that brought the universe suddenly and spectacularly into existence. Shortly after, the infant universe cooled dramatically...
It looks like fireflies flickering in the darkness. Slowly, more and more amass, lighting up the screen in large chunks and clusters.
When Yen-Jie Lee came to MIT as a graduate student in 2006, it was a bit of a culture shock. The aspiring particle physicist had studied physics at National Taiwan University before his career took a ...
A new special edition of EPJ Special Topics brings together several papers that detail our understanding of Quark-Gluon Plasma (QGP) and the processes that transformed it into the baryonic matter we a...
In 1983, astrophysicists at the Center for Astrophysics | Harvard & Smithsonian (CfA) released a cosmic map using 2,400 galaxies. Now, CfA scientists are aiming to map 30 million.
Determining how rapidly the universe is expanding is key to understanding our cosmic fate, but along with more precise data comes a conundrum. Estimates based on measurements in our current universe d...
A team of scientists has detected the presence of a high-energy neutrino -- a particularly elusive particle -- in the wake of a star's destruction as it is consumed by a black hole.The discovery is a ...
The supersharp radio "vision" of the U.S. National Science Foundation's Very Long Baseline Array has revealed previously unseen details in a jet of material ejected at three-quarters the speed of...
From a mountain high in Chile's Atacama Desert, astronomers at the U.S. National Science Foundation's Atacama Cosmology Telescope (ACT) have taken a fresh look at the oldest light in th...
In the 13.8 billion-year-old universe, most galaxies form gradually, reaching their large mass relatively late.But the National Science Foundation-funded discovery of a massive rotating disk gala...
Astronomers using National Science Foundation radio telescopes have demonstrated how a combination of gravitational-wave and radio observations, along with theoretical modeling, can turn the mergers o...
