A Supernova Remnant

This tangled web is an object known as SNR 0454-67.2. It’s a supernova remnant created after a massive star ended its life in a cataclysmic explosion and threw off its constituent material out into surrounding space. SNR 0454-67.2 lies in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. The remnant is probably the leftovers from a Type Ia supernova explosion. A Type IA supernova is the death of a white dwarf star that grown by siphoning material from a stellar companion until it reached critical mass and exploded.

A Star Cluster in Another Galaxy

The clump of stars in the center of the picture is the globular cluster NGC 1898. It’s not in our galaxy. It’s near the middle of the Large Magellanic Cloud, a satellite galaxy of The Milky Way which contains a rich population of star clusters, making it an ideal laboratory for investigating star formation.

Monster Stars

R136 observed with WFC3This Hubble image shows the central region of the Tarantula Nebula in the Large Magellanic Cloud. The young and dense star cluster R136 can be seen the lower right of the image. This cluster contains hundreds of young blue stars. One of them is the most massive star detected in the universe to date.

Dozens of stars in the cluster exceed 50 solar masses, and nine very massive stars are all more than 100 times more massive than the Sun. The most massive is R136a1—weighing in at more than 250 solar masses.

Rotating a Galaxy

This animation illustrates the rotation rate of the Large Magellanic Cloud (LMC). Hubble Space Telescope observations have been used to determine that the central part of the LMC completes a rotation every 250 million years. It takes more than 10 million years for even the small amount of rotation illustrated in this video.

The Large Magellanic Cloud

This is not a photograph. It’s a map of radiation detected by ESA’s Gaia spacecraft while observing the Large Magellanic Cloud. The color of each pixel was derived from data taken through different filters.

The image is dominated by the brightest, most massive stars. They outshine their fainter, lower-mass counterparts. The central bar of the LMC is readily visible, as are individual regions of star formation such as 30 Doradus, visible just above the center of the galaxy.
