Scientists have been all aflutter since several space-based detectors picked up a powerful gamma-ray burst (GRB) in October 2022—a burst so energetic that astronomers nicknamed it the BOAT (Brightest ...

An international team of astronomers has performed photometric and spectroscopic observations of a distant Type Ibn supernova known as SN 2024acyl. Results of the observational campaign, published ...

On 24 October 2025, South Africa's MeerKAT radio telescope detected a signal that has left astronomers stunned. The ...

Light from 23 distant galaxies, identified with red rectangles in the Hubble Space Telescope image at the top, were combined to capture incredibly faint emission from eight different elements, which ...

Two slitless Bragg spectrometers were successfully used on a Sun-pointed Skylark rocket flight (SL 304) on May 5, 1966, to measure the solar X-ray emission below 25 Å. The crystals were of potassium ...

A set of five gas discharge tubes are arranged such that when they are touched with a Tesla coil, their characteristically colored emission spectra are seen. The Tesla coil can burn your skin on ...

ABSTRACT Internal kinematics is rapidly becoming an important tool for understanding the nature and evolution of distant galaxies. However, the very low signal‐to‐noise ratios involved in these ...

This is a preview. Log in through your library . Abstract Radial velocities and relative fluxes of emission lines in the spectrum of RS Oph obtained 70 days after the 1985 outburst are presented. The ...

Two astrophysicists have finally solved a 20-year-old astrophysical puzzle concerning the lower-than-expected amounts of the element sulphur found in Planetary Nebulae (PNe) in comparison to ...
