Are you ready for some astronomical football?
Astronomers using the Hubble Space Telescope say they have found a gaseous planet about the size of Jupiter that is shaped like the pigskin thrown around on Sundays.
The planet -- WASP-121b -- is 900 light-years from Earth. It's also ridiculously hot.
WASP-121b is orbiting "dangerously close" to its star, according to NASA. So close that it's on the verge of being ripped apart by the star's gravity.
"This hugging distance means that the planet is football-shaped due to gravitational tidal forces," NASA said.
To say the temperature on WASP-121b is unbearable would be a significant understatement. WASP-121b's upper atmosphere is 4,600 degrees Fahrenheit, about 10 times greater than any known planetary atmosphere, according to NASA.
NASA says heavy metals that would condense into clouds on other planets are instead escaping from WASP's atmosphere. Heavy metals are elements heavier than hydrogen and helium.
Magnesium and iron gases are streaming away from the planet. NASA says it's the first time astronomers have found a hot, Jupiter-like planet that does this.
"With WASP-121b, we see magnesium and iron gas so far away from the planet that they're not gravitationally bound," lead researcher David Sing of the Johns Hopkins University said.
Facts about Hubble
- Named for astronomer Edwin Powell Hubble, who determined by observing other galaxies that the universe was expanding -- the basis for the big bang theory.
- Deployed from Space Shuttle Discovery on April 25, 1990. It was serviced five times during subsequent shuttle missions, with the last coming in May 2009.
- Hubble orbits 340 miles above the Earth at 17,000 mph.
