A black patch of sky looks empty until you stop taking it for granted. That is the starting point of a theory from Professor Richard Feynman, built around what sounds like a child’s question, why the ...

The Dark Energy Spectroscopic Instrument, or DESI, has finished its planned 3D map of the universe — but the work is far from over. Carnegie Mellon University researchers are already pushing the ...

Cosmologists have spent decades trying to pin down exactly how fast the universe is flying apart and whether that rate is ...

Astronomers have confirmed a rare pair of merging quasars, J2037–4537, from just 1 billion years after the Big Bang, using ...

The Hubble Space Telescope launched in 1990 and marks 36 years in space later this month. Each year, NASA shares a photo taken by Hubble to celebrate the space telescope's anniversary. The photos show ...

NASA's Hubble Space Telescope recently revisited the Crab Nebula, a supernova remnant, 25 years after its initial observations. The new images reveal stunning details of its intricate structure and ...

Here’s what you’ll learn when you read this story: However, nailing down the universe’s exact expansion rate (known as the Hubble constant, or H₀) hasn’t been easy. Today scientists rely on two ...

A dazzling new Hubble image peels back the layers of the mysterious Egg Nebula, a rare and fleeting phase in a Sun-like star’s death just 1,000 light-years away. Hidden inside a dense cocoon of dust, ...

A major international effort has produced an ultra-precise measurement of the Universe’s expansion rate, confirming it’s faster than early-Universe models predict. By linking multiple ...
