A team of astronomers using a Yale supercomputer have determined for the first time that galaxies in denser environments are as much as 25% larger than their counterparts in less dense regions of the ...

If Earth had the same diameter as the head of a pushpin, how much would all of the other celestial bodies in the universe need to shrink to scale proportionally? It’s a fun, ridiculous question and ...

Astronomers have assembled the largest-ever compilation of high-precision galaxy distances, called Cosmicflows-4. How old is our universe, and what is its size? A team of researchers led by University ...

NASA's James Webb Space Telescope has helped astronomers determine the distance to nearly 200 galaxies and galaxy clusters formed in the universe's early days. One of the first publicly released ...

A team of astronomers from the International Center for Radio Astronomy Research (ICRAR) has released new data from an ...

Astronomers have detected an enormous cosmic filament stretching 850,000 light-years across the early universe, offering a ...

One of the ways massive stars, those at least 10-times bigger than the Sun, reach their end is in a supernova—an enormous explosion caused by the star’s core running out of fuel. One consequence of a ...

The discovery that the universe extends beyond the Milky Way galaxy was a pivotal moment in astronomy. In 1925, astronomer Edwin Hubble identified a Cepheid variable star, known as V1, in the ...

How old is our universe, and what is its size? A team of researchers led by University of Hawaiʻi at Mānoa astronomers Brent Tully and Ehsan Kourkchi from the Institute for Astronomy have assembled ...
