Scientists Baffled by Neptune's Temperature Swings
Temps should be 'slowly growing warmer, not colder' amid southern summer
- Neptune's southern hemisphere has spent the last 17 years in its summer season, yet global temperatures have plummeted.

Newly Discovered Planet 'Is a Very Hellish World'
TOI-1431b is 3 times the size of Jupiter and hotter
- Being 490 light-years from Earth, a newly discovered planet would be difficult to get to. That's just as well. "This is a very hellish world," an astrophysicist said. That's because, the team that pinpointed it found, TOI-1431b is inhospitably hot—hot enough to melt metal, hotter...
