Key points

From ScienceDaily’s report

NASA's JWST studied SIMP 0136, a brown dwarf 20 light-years away.
Researchers found three recurring weather states driven by temperature and clouds.
Two main factors explain atmospheric variability: temperature changes and vertical cloud structure.
Study used Principal Component Analysis to decode light variations over rotations.
Findings suggest a surprisingly organized weather system on a distant world.

Why it matters. The pattern reveals an unexpectedly organized atmosphere on a brown dwarf.

What to watch. Changes among the three recurring states.

“Astronomers discover green star 280 light-years away; what makes it glow green”

Key points from The Times of India

Astronomers identified white dwarf WD J1330+6435 in Draco about 280 light-years away.
Green hue arises from sodium-helium interactions under extreme atmospheric conditions.
Study published in RAS Techniques and Instruments analyzes unusual colours of white dwarfs.
Researchers used spectral data and colour-perception models to determine appearance.
The star's temperature is estimated around 4,000 degrees Celsius and is Earth-sized.
