3/4 Around the young star lies a dense disc of dust and gas where astronomers have spotted a prominent spiral structure with a twist that marks the site where a planet may be forming.

4/4 This feature, found in 2019 and early 2020, could be the first direct evidence of early planet formation in a young stellar disc.

1/10 All eyes on #Betelgeuse these days. What’s happening to this well-known star in the constellation of #Orion?
2/10 Normally one of the brightest stars in the sky, it’s now fainter than ever before in recorded history.
3/10 Astronomers think the star is preparing to blow, going #supernova. Think cosmic time scales though. This artist’s impression shows #Betelgeuse shedding its material. eso.org/public/images/…

2/ The discovery of exoplanet #51Pegasib was announced on 6 October 1995 by Mayor and Queloz, who detected it using the ELODIE spectrograph at the Observatoire de Haute-Provence in France.
3/ The discovery revolutionised astronomy, initiating an entirely new field and new instruments focused on finding and characterising exoplanets.
