Abstract Long-period radio transients are an emerging class of extreme astrophysical events of which only three are known. These objects emit highly polarized, coherent pulses of typically a few tens of seconds duration, and minutes to approximately hour-long periods. Although magnetic white dwarfs and magnetars, either isolated or in binary systems, have been invoked to…

A dim star in the night sky 3,000 light-years from our solar system could soon become visible to the naked eye for the first time since 1946 — and you can easily find it in the night sky. The “Blaze Star” — officially called T Coronae Borealis (T CrB) — is expected to brighten significantly…

Vikas Chander from Delhi, India The Seagull Nebula spans the constellations of Canis Major and Monoceros. Its head is the emission nebula IC 2177 and its broad, billowing wings are part of Sharpless 2–296. Note the bow shock around the star FN Canis Majoris, which forms as the star plows through surrounding gas, like the…

I spy something red: Some of the molecules found on the surface of Arrokoth, a reddish, lumpy world located in the Kuiper belt. By bombarding samples of frozen methane with simulated cosmic rays, the research team succeeded in recreating Arrokoth’s unusual colour slope.

The universe burst into existence 13.8 billion years ago. What happened in that earliest moment is of intense interest to anyone trying to understand why everything is the way it is today. “I think this question of what happens at the beginning of the universe is a profound one,” said David Spergel, president of the…

Space exploration has always fascinated people and captured their imagination. From the time humans first looked up at the stars to the present day, we have been driven to understand the mysteries of the universe beyond our planet. In recent decades, space exploration has made significant strides, with multiple nations launching probes and missions to…

Cavendish-like: A schematic diagram of the proposed experiment on gravitational interaction between two torsion balances. Two torsion pendula are placed with their equilibrium orientations (dashed lines) in parallel and allowed to interact through gravity. An electromagnetic shield is placed between the two pendula to suppress electromagnetic interactions. The rotational degrees of freedom of each pendulum…
