72 New Planets, Including a World Covered in Volcanoes 🌋🌋🌋 We've added LP 791-18 d, a newly discovered world that may be as volcanically active as Jupiter's moon Io, and a new #JWST emission spectrum for GJ 1214 b. exoplanetarchive.ipac.caltec…

Earth-size exoplanet LP 791-18 d may have volcanic outbursts as often as Jupiter’s moon Io, the most volcanically active body in our solar system! That activity could help the planet maintain an atmosphere.

300 light-years from Earth, two planets still glowing from formation 17 million years ago, were directly imaged. We can't see exoplanets beyond a few pixels of light because of the distances. But what glorious light! (Seen with the star, at upper left.) go.nasa.gov/41wPxin

A blip in brightness & a world's demise Astronomers saw a flash in a sky survey, and found it again in infrared: the first direct observation of a star devouring a planet. Our Sun, and perhaps our planet, will face a similar fate in 5 billion years. go.nasa.gov/42fREYs

A distant planet outside our solar system – and unlike anything in it – gets a look by @NASAWebb. It’s the closest look yet at the mysterious world, a “mini-Neptune” that was largely impenetrable to previous observations! go.nasa.gov/42IoS2V

Five planets are locked in a rhythmic dance around their Sun-like star. It's one of the best examples we have of orbital resonance, where the planets move in synchronicity. There's also evidence of a sixth world in this cosmic ballroom!💃🏾 go.nasa.gov/42L7DOJ

What's YOUR favorite planet? There are eight in our solar system and billions beyond, and we've confirmed 5,347 of them. So, if you don't have a favorite yet, stay tuned! Maybe we're still looking for it? Exoplanets.nasa.gov

A bright star, visible in Earth’s Southern sky, has a secret. The well known Fomalhaut debris disk, imaged by @NASAWebb, has inner rings and an undulating structure that hints at unseen planets. go.nasa.gov/42dH7h6

We’ve found exoplanets with two, or even three, suns. What could conditions on those planets be like? We checked in with exoplanet scientists to see: exoplanets.nasa.gov/news/143…

We've long thought that, at the end of their lives, stars like our Sun swell up to 100 times their former diameter and consume surrounding planets. Now, we've seen it. 15,000 light-years away, a hungry star consumed a nearby planet. go.nasa.gov/42fREYs

📷 The NASA/ESA/CSA James #Webb Space Telescope has found hints of water vapor around the rocky exoplanet GJ 486 b. 💧 If the water vapor is associated with the planet, it could indicate that it has an atmosphere despite its scorching temperature and close proximity to its star. ☀ However, the team cautions that the water vapor could be on the star itself – specifically, cool starspots – and not from the planet at all. 🔗esa.int/ESA_Multimedia/Image…

Could a water signature be coming from a star?! When @NASAWebb studied the exoplanet GJ 486 b and its host star, it saw H2O. On the planet, it would indicate an atmosphere. The water could also be vapor lingering in a cooler sunspot of its red dwarf star! go.nasa.gov/40UaRy1
