NASA's Astronomy Picture of the Day highlights the spiral structure of the Triangulum Galaxy and the star-forming regions within the Carina Nebula.
Key facts
- •Messier 33 is considered a satellite of the Andromeda Galaxy.
- •Variable stars in M33 are used by astronomers as a cosmic yardstick to measure the distance scale of the universe.
- •The dust pillar in the Carina Nebula contains a massive star approximately 19 times the mass of the Sun.
- •The Carina Nebula image is a collaborative effort involving NASA, ESA, and CSA.
NASA has showcased two distinct celestial features through its daily astronomy series. The features include the Triangulum Galaxy, a spiral galaxy located in the northern sky, and a dust pillar within the Carina Nebula captured by the James Webb Space Telescope.
By the numbers
The Triangulum Galaxy
Messier 33, also known as the Triangulum Galaxy or the Pinwheel Galaxy, is a face-on spiral galaxy spanning over 50,000 light-years in diameter. Located approximately 3 million light-years from the Milky Way, it is the third-largest member of the Local Group. The galaxy is characterized by blue star clusters and pinkish star-forming regions, including the prominent NGC 604 region.
Star Formation in the Carina Nebula
The James Webb Space Telescope captured a dust pillar in the Carina Nebula, situated roughly 7,500 light-years away. This structure, shaped by radiation and stellar winds, contains a compact cluster of approximately 70 stars estimated to be 1.3 million years old. The region is influenced by the Eta Carinae stellar system, which is more luminous than 5 million suns.
