Graham tried tweaking the CNN approach so that the kernel would only be placed on 3-by-3 sections of the image that contain at least one pixel that has nonzero value (and is not just blank).…

Most celestial objects—from stars and nebulas to quasars and galaxies—emit light at a range of wavelengths. Some include visible light, which is how astronomers are able to photograph them…

The NANOGrav team was essentially able to turn the Milky Way into a giant gravitational wave detector by measuring the signals from these pulsars to determine when a wave nudged them. The…

During fleeting fits, the sun occasionally hurls a colossal amount of energy into space. Called solar flares, these eruptions last for mere minutes, and they can trigger catastrophic…

Throngs of satellites are streaking across the Hubble Space Telescope’s field of view, leaving what look like scratch marks on space photos and hindering scientists’ work. Teeming swarms of…

Thanks to data from a magnified, multiply imaged supernova, a team led by University of Minnesota Twin Cities researchers has successfully used a first-of-its-kind technique to measure the…

If you are a star-gazing enthusiast, the sky is now the limit, quite literally. From immersive ‘space travel’ experiences to observing the night sky in a cold desert, there are a whole lot…

But the word “most” is important. The ACT team’s findings agree with studies of the CMB made with instruments like the European Space Agency’s Planck telescope, which together cover the…

Intriguingly, this kind of decoherence will occur anywhere there is a horizon that only allows information to travel in one direction, creating the potential for causality paradoxes. The…

In the early 2000s, Phil Plait wrote his first book, Bad Astronomy, which debunked conspiracy theories and fallacies, like the idea that NASA faked the moon landings in the 1970s or that…
