‘At the edge of what we thought possible’: Astronomers find extremely rare star from ancient universe

“Cosmic archaeologists” have discovered an iron-deficient second-generation star, which provides evidence of how ancient stars enriched their successors.

X-ray spacecraft watches monster black hole wake up and fire cosmic bullets at starburst galaxy

The research could shed light on how black holes vomit out matter and how this influences their home galaxies.

Ryugu asteroid sample contains all five key components of DNA, scientists find

A sample collected by the Hayabusa 2 spacecraft from the spinning top-like asteroid contained the nucleobases adenine, guanine, cytosine, thymine, and uracil.

How fast is the universe expanding? Astronomers may be one step closer to resolving ‘Hubble trouble’

The local universe may be expanding more slowly than previously thought, a discovery that could relieve a pesky discrepancy known as the Hubble tension.

Astronomers discover a new type of planet that probably smells like rotten eggs

Using the James Webb Space Telescope, astronomers have discovered an example of a new class of exoplanet, and it smells like rotten eggs.

Deep underground, a telescope may soon detect ghosts of stars that died before Earth existed

With the help of an extremely powerful telescope deep underground in Japan, astronomers may be able to catch a glimpse of ghost particles from long-dead stars.

A state of matter last seen just after the Big Bang may exist inside neutron stars — and scientists think they can prove it

As binary neutron stars spiral around each other to merge, their gravitational tidal forces distort each other’s shape and structure, potentially revealing clues as to what lies within them.

Why are some stars always visible while others come and go with the seasons?

So, why is it that Orion is not always visible in the night sky, and certainly not in the same location month after month, while the Big Dipper always is?

Hubble and NASA space telescopes track ‘game-changing’ gamma-ray burst back to neutron star collision in ‘forbidden’ region of the universe

Astronomers have tracked a powerful blast of radiation back to its source, finding a neutron star collision within colliding galaxies.
