This cat-like nebula is sculpted by two massive stars, each over 20x the Sun’s mass. Expanding shells of ionized gas make it glow, while dense regions collapse under gravity, forming new stars—a stellar nursery emerging from cosmic chaos.

JWST captured Neptune’s auroras for the first time! Neptune has a tilted magnetic field, shifting auroras away from its poles. Webb also found Neptune’s upper atmosphere cooled by hundreds of degrees—likely why they stayed hidden so long.

The Sun loses about 4.2 million tons of mass every second due to nuclear fusion, where hydrogen atoms combine to form helium, releasing vast amounts of energy. This process sustains the Sun’s energy output and is key to life on Earth. #science #physics #universe #space #facts
