Pulsar

A student started a chase for the stars after detecting unusual sound waves in archival data.

Astronomers in Europe said they have discovered what might be the smallest exoplanet found so far. If real, it is smaller than our moon and orbits a pulsar. The post Possible smallest exoplanet found … and it orbits a pulsar first appeared on EarthSky.

Learn how researchers have interpreted the story of one particular fast radio burst that emerged from a neutron star 200 million light-years away.

MIT astronomers pinned down the origins of at least one fast radio burst, a brief and brilliant explosion of radio waves emitted by an extremely compact object. The team's novel technique might also reveal the sources of other FRBs.

Astronomers have finally pinpointed the source of slowly repeating radio bursts: a red dwarf star with a possible white dwarf binary companion. The post Odd, slowly repeating radio bursts traced to red dwarf star first appeared on EarthSky.

New observations from Webb confirms previous Hubble measurements of distances between nearby stars and galaxies, offering a crucial cross-check to address the mismatch in measurements of the Universe's mysterious expansion. Known as the Hubble tension, the discrepancy remains unexplained even by the best cosmology models.

Astronomers using the MeerKAT Pulsar Timing Array, an international experiment that uses the MeerKAT Radio Telescope in South Africa, have uncovered further evidence of gravitational wave signals originating from merging supermassive black holes.

Science often accommodates audacious proposals.

A "flame-like" beam.

It's extraordinarily dense and fast.

A new study reveals that Generation 2 Starlink satellites are leaking up to 30 times more radio waves than their predecessors. If SpaceX continues to deploy the newer versions as planned, we could reach an "inflection point" where astronomers can no longer properly study the cosmos, researchers warn.

Right now, it looks like cosmology is at a tipping point. Will the James Webb telescope resolve the issue by revealing new physics?

Nestled between mountains in a secluded corner of West Virginia, a giant awakens: the Green Bank Telescope begins its nightly vigil, scanning the cosmos for secrets.

A mysterious ring invisible at all wavelengths except radio could be a trace of a dramatically unstable star shedding its skin.

The search for extraterrestrial life has profound physical, mental and spiritual implications, says Nathalie Cabrol in The Secret Life of the Universe—and it belongs to everyone

Ten neutron stars found lurking in the Milky Way include cosmic black widows killing stars with "webs" of viscous plasma and a speed demon that spins over...

New calculations reveal that pairs of supermassive black holes can merge into a larger black hole because of previously overlooked behavior of dark matter particles, proposing a solution to the long-standing 'final parsec problem.'

Do dead stars glow? A strange gravitational phenomenon could be generating enormous amounts of light around neutron stars, new research suggests.

On Aug. 24, 2023, more than three decades after the first confirmation of planets beyond our own solar system, scientists announced the discovery of six new exoplanets, stretching that number to 5,502. From zero exoplanet confirmations to more than 5,500 in just a few decades, this new milestone marks another major step in the journey to understand the worlds beyond our solar system.

Pulsars that emit radio waves "glitch" as they rotate – this seems to be caused by interruptions to swirling vortices inside these ultra-dense stars
