A symmetrical, glowing nebula shaped like an ant stretches out in opposite directions from a bright central star. The twin lobes of the nebula are narrow, curving outward and then tapering off, creating the appearance of pincers or insect legs. The structure is reddish-orange with fine details of gas and dust, surrounded by dark space. The central region is bright and compact, highlighting the star system driving the outflow.

Supernova SN 2024aecx, captured by ZTF, showed signs of shedding material before it exploded. Studying this helps astronomers better understand the final stages of massive stars.

Planetary nebulae are beautiful, expanding shells of gas and dust ejected from dying low-to-medium mass stars. They are not related to planets in any way, despite their name. #PlanetaryNebulae #StellarDeath #Nebulae

Planetary nebulae, the beautiful, expanding shells of gas and dust, are created by the death throes of sun-like stars. #PlanetaryNebulae #StellarDeath #Nebulae

Nebulae are vast clouds of gas and dust in space, some of which are stellar nurseries where new stars are born. Others are the remnants of stars that have died. #Nebulae #StarFormation #StellarDeath

False-color radio image of a supernova remnant in M82 galaxy, 12 million light-years away. The image, 1.5 light-years across, was created using Very Long Baseline Interferometry (VLBI), combining data from 20 radio telescopes across Earth. Shows detailed structure of expanding stellar debris cloud.
