Astronomers are getting closer to solving the enduring mystery of fast radio bursts

Fast radio bursts shine in the sky above Earth. | Credit: NRAO Outreach/T. Jarrett (IPAC/Caltech); B. Saxton, NRAO/AUI/NSF Fast radio bursts (FRBs) are intense, short-lived bursts of radio waves from beyond the Milky Way and can emit in a thousandth of a second the same energy that it takes the sun three days to emit.… Read More »

Scientists find slowest spinning ‘radio neutron star’ – breaks all dead star rules

Astronomers have discovered the slowest spinning radio-emitting neutron star ever seen; It takes almost an hour to complete a full rotation. That might sound pretty fast, but these dead stars are known to spin so fast that some make 700 full rotations each. second. Even the slowest of the nearly 3,000 radio-emitting neutron stars, or… Read More »

Astronomers call for radio silence on far side of moon

There is a growing and passionate call for radio silence to be maintained on the far side of the moon. A first-of-its-kind international symposium is being held this week, turning up the volume to ponder the possibility of preserving real estate on the far side of the moon for exclusive scientific purposes. Even though the… Read More »

Mathematically perfect exoplanet system — a great place to look for alien technology

Late last year astronomers discovered a fascinating star system only 100 light years away from us. Neptune’s six subplanets orbit very close to their host star in mathematically perfect orbits, attracting the attention of scientists searching for alien technology or technosignatures, which they claim would provide convincing evidence of advanced life beyond them. Soil. To… Read More »

Mystery of vast ‘cosmic ORCs’ (strange radio circles spanning entire galaxies) may be solved

Scientists may have finally solved the mystery of cosmic ORCs, or “strange radio circles” as they are officially known, that are 10 times as wide as the Milky Way and large enough to encompass entire galaxies. A team of astronomers led by University of California San Diego Professor of Astronomy and Astrophysics Alison Coil pointed… Read More »

Can stars form around black holes?

In the 1930s, physicist and engineer Karl Jansky detected a continuous source of radio waves when he pointed his radio antenna at the center of our galaxy. After some analysis, scientists realized that these radio waves were emitted by something much farther away than our planet. Sun – but oddly enough, they were comparable in… Read More »
