A star's magnetic field must be considered in order to correctly determine the characteristics of their exoplanets from observations by space telescopes such as Kepler, James Webb, or PLATO. This is demonstrated by new model calculations presented today in the journal Nature Astronomy by a research group led by the Max Planck Institute for...
The threat of an asteroid colliding with Earth is a real and potentially catastrophic danger. While the probability of a large asteroid impact in our lifetimes is low, the consequences could be devastating,...
A team of physicists has developed a method to detect gravity waves with such low frequencies that they could unlock the secrets behind the early phases of mergers between supermassive black holes, the heaviest...
Reports that NASA’s James Webb Space Telescope broke the universe may have been exaggerated.
In its first images, JWST captured what appeared to be gargantuan galaxies in the early universe — ones much too big...
Satellites are more likely to be at risk from high-speed solar wind than a major geomagnetic storm according to a new UK-US study published this week in the Journal Space Weather.
Researchers investigating the space...
From 20th April to 12th May, Armagh Observatory and Planetarium are delighted to be hosting the Ec(h)o exhibition by Csilla Toldy. Csilla has worked...
The afterglow of the Big Bang reveals the geometry of the universe. Einstein’s field equations describe gravity not as a force, but rather a
property...

Scientists have developed enhancements to the shape-from-shading technique, greatly improving the efficiency and accuracy of mapping the Moon’s surface. This innovation aids mission planners...
The H-R diagram was created around 1910 by Ejnar Hertzsprung and Henry Norris Russell, plotting stars’ absolute magnitudes or luminosities against their colors or...
