International team detected radio bubbles with South Africa’s MeerKAT telescope. A gigantic, balloon-like structure has been hiding in plain sight, right in the center of…
An artist’s impression of the rocky exoplanet Kepler-186f, which is one of the most promising candidates for a planet could potentially be habitable, but how…
This image, taken with the NASA/ESA Hubble Space Telescope, shows a massive galaxy cluster, about 4.6 billion light-years away. Along its borders four bright arcs…
Within a galaxy hosting around 300 billion stars, here the NASA/ESA Hubble Space Telescope has captured a mere handful or two — just about enough…
