WASP-189b is one of the most ‘extreme’ planets ever discovered and its star holds some surprises too. — The European Space Agency (ESA) satellite CHEOPS is living up to its potential. The first study developed with data provided by the exoplanet hunter — launched at the end of last year — reveals its observation of one of the most remarkable exoplanets ever discovered — WASP-189b. The planet in…

The first identification of an ultraviolet aurora around the comet Chury is further evidence that nearly half a decade after the end of the Rosetta mission, the ESA’s historic project is still delivering breakthrough science. — Earth’s aurora provides a stunning visual light show called the Northern Lights which has fascinated observers for centuries. But astronomers have discovered that other bodies such as other planets and moons have auroras too. …

Astronomers have discovered the Phoenix Stream — the remains of a shredded globular cluster of stars. These fossilised remains of an early star system could throw theories of galactic evolution into question. — Astronomers have spotted the shredded remains of an ancient collection of stars, an archaeological artifact of the early Universe. The globular cluster was ripped apart by the gravitational influence of the Milky Way over two billion years ago. forming a ‘stream’ of stars in the Phoenix constellation.

The exposed interior of a newly discovered exoplanet offers astronomers a unique opportunity to research the conditions beneath the surface of planets. A newly discovered exoplanet — TOI 849 b — located 730 light-years from Earth offers astronomers a unique opportunity to study the interiors of planets. The exoplanet —…

Astronomers have spotted huge superflares millions of times more powerful than solar flares, and giant magnetic spots on hot stars. The finding could be a key step towards understanding how magnetic fields affect stellar bodies. — The surfaces of hot stars hidden in stellar clusters are riddled with giant magnetic spots and superflare explosions millions of times more powerful than those seen on the Sun says a team of astronomers from INAF Astronomical Observatory of Padua in Italy.

By studying Westerlund 2, a dense star cluster containing stars 100 times the size of the Sun, astronomers have discovered why planets don’t form around some stars. Using the Hubble Space Telescope researchers have conducted a pioneering 3-year study of the massive dense young star cluster Westerlund 2. In the…

Using the ESPRESSO spectrograph, astronomers from the University of Geneva have confirmed the existence of an Earth-like exoplanet orbiting the nearest star to ours. The discovery comes with a surprise, the planet may have a companion. Proxima b an Earth-like exoplanet orbiting in the habitable zone of the nearest star…

The confirmation of a rare type of massive galaxy, shaped into a doughnut-like ring, in the early Universe could cause a rethink of how galaxies evolve. — Astronomers have discovered an incredibly rare type of galaxy described as a “cosmic ring of fire” that existed in the Universe 11 billion years ago. …
