## Planet Disappears After 7 Years
A gas giant exoplanet like Jupiter went missing after astronomers spent seven years watching it with NASA's TESS telescope.
## Planet's Orbit Acts Weird
The planet, TOI-2535 b, had been acting a little weird for a while. Each time it passed, which astronomers call a transit, it arrived as much as six hours early or late.
## Transits Grow Shorter
The crossings also grew shorter and fainter until the planet stopped showing up earlier this year.
## Orbit Tilted
The planet's orbit is tilting so quickly that its transit disappeared while we were watching.
## Hot Jupiter Formation
Scientists think most hot Jupiters formed through violent encounters, but this pair spiraled in slowly together.
## What Happened Next
The planet still circles its star but now passes above or below it from Earth's view.
## Key takeaway

NASA's TESS telescope detected a gas giant exoplanet vanishing after seven years of observation as its orbit tilted, revealing how hot Jupiters form.
