Beautiful nebula, violent history: Clash of stars solves stellar mystery

When astronomers looked at a stellar pair at the heart of a stunning cloud of gas and dust, they were in for a surprise. Star pairs are typically very similar, like twins, but in HD 148937, one star appears younger and, unlike the other, is magnetic. New data suggest there were originally three stars in the system, until two of them clashed and merged. This violent event created the surrounding cloud and forever altered the system's fate.

Twinkle twinkle baby star, 'sneezes' tell us how you are

Researchers have found that baby stars discharge plumes of gas, dust, and magnetic flux from their protostellar disk. The protostellar disk that surrounds developing stars are constantly penetrated by magnetic flux, and if too much magnetic flux remained, the resulting object would generate a magnetic field stronger than any observed protostar. These newly discovered discharges of magnetic flux, or 'sneezes' as the researchers describes them, may be a vital step in proper star formation.

CHEOPS detects a 'rainbow' on an exoplanet

The CHEOPS space telescope is providing new information on the mysterious exoplanet WASP-76b. This ultra-hot giant is characterized by an asymmetry between the amount of light observed on its eastern terminator -- the fictitious line that separates its night side from its day side -- and that observed on its western terminator. This peculiarity is thought to be due to a 'glory', a luminous phenomenon similar to a rainbow, which occurs if the light from the star -- the 'sun' around which the exoplanet orbits -- is reflected by clouds made up of a perfectly uniform substance. If this hypothesis is confirmed, this would be the first detection of this phenomenon outside our solar system.
