In 2011, three physicists won the Nobel Prize for showing that the expansion of the universe speeds up, which is usually attributed to aa mysterious type of energy called “dark energy”. But last year, though, a different group published research showing that universal expansion isn’t actually getting faster. Since then, the two groups have engaged in a whole bunch of back-and-forth refuting each

Webb found the same unexplained infrared fingerprint on two frozen worlds.

The first direct measurements of exoplanet magnetic fields reveal that ultra-hot Jupiters possess strong magnetism that shapes their atmospheres and may provide new insights into planetary habitability. Astronomers have achieved a major advance in the study of worlds beyond our Solar System by estimating the strength of the magnetic fields surrounding seven ultra-hot Jupiters. The [...]

Researchers have identified the most distant dormant black hole known, dating back to the universe’s early history. Astronomers have long relied on brilliant quasars, supermassive black holes actively feeding on surrounding matter, to study the early universe. Yet these luminous objects reveal only part of the story. Now, researchers have detected the most distant dormant [...]
