A Carbon Forge on a Windy Planet Around a Pulsar
A wind blowing against the planet's rotation stokes a carbon forge. That is what the atmosphere of PSR J2322-2650b looks like: a Jupiter-like companion to a millisecond pulsar.
Moons of Distant Planets: What's Keeping Us from Seeing Them
The light from a distant star is never steady. It shimmers like heat over hot asphalt. When astronomers pointed JWST at the star TOI 700, they saw this shimmer especially clearly: every 16 minutes, the brightness changed by a tiny fraction, just 46 parts per million.For comparison: if you placed a light bulb a kilometer away, this change would be…
A Lava World with a Cool Face
A hot skillet on the stove glows in the dark, but if you cover it with a lid, the heat escapes more slowly and the surface doesn't look as bright. That's roughly the situation on planet HD 3167 b: it always shows the same face to its star, and the dayside is heated to temperatures that melt rock.
The Universe's Recipe: A Sub-Saturn Around a Cool Star Reveals a Standard Method for Making Giants
Some 158 light-years away, around the dim star TOI-6894, a red dwarf, a planet moves leisurely. Its year lasts less than two Earth days, yet it is a cool world with an equilibrium temperature around 420 K, just a bit warmer than a sauna.
