Hubble Observes Massive Stars Forming In Nebula

Stars are born from turbulent clouds of gas and dust that collapse under their own gravitational pull. As the cloud collapses, a dense, hot core forms and begins to accumulate dust and gas, creating a protostar. This star-forming nebula in the constellation Aquila, G035.20-0.74, is known to produce a particular type of massive star known … Read more

Hubble Observes a Superbubble Deflating a Nebula

N44 is a complex nebula filled with bright hydrogen gas, dark dust streaks, massive stars and many populations of stars of different ages. One of its most distinctive features, however, is the dark, starry gap called the “superbubble” visible in this Hubble Space Telescope image in the upper central region. The hole is about 250 … Read more

Hubble Observes the First Moments of Supernova Formation

As a witness to a violent death, NASA’s Hubble Space Telescope recently gave astronomers an unprecedented and comprehensive view of the first moments of a star’s cataclysmic death. Hubble’s data, combined with other observations of the doomed star made by space and ground-based telescopes, could give astronomers an early warning system for other stars about … Read more

Hubble Observes Peculiar Arp 86 Galaxy Pair In Preparation For James Webb Studies

This NASA/ESA Hubble Space Telescope observation shows Arp 86, a peculiar pair of interacting galaxies that lies about 220 million light-years from Earth in the constellation Pegasus. Arp 86 is composed of two galaxies NGC 7752 and NGC 7753 – NGC 7753 is the large spiral galaxy dominating this image, and NGC 7752 is its … Read more
