Hubble Catches a Bounty of Stars and Cosmic Dust













NASA - Hubble Space Telescope patch.

June 28, 2019


This Hubble Space Telescope image shows the spiral galaxy Messier 98, which is located about 45 million light-years away in the constellation of Coma Berenices (Berenice's Hair). The galaxy was discovered in 1781 by the French astronomer Pierre Méchain, a colleague of Charles Messier, and is one of the faintest objects in Messier’s astronomical catalog.

Messier 98 is estimated to contain about a trillion stars, and is full of cosmic dust — visible here as a web of red-brown stretching across the frame — and hydrogen gas. This abundance of star-forming material means that Messier 98 is producing stellar newborns at a high rate; the galaxy shows the characteristic signs of stars springing to life throughout its bright center and whirling arms.

This image of Messier 98 was taken in 1995 with the Wide Field and Planetary Camera 2, an instrument that was installed on Hubble from 1993 until 2009. These observations were taken in infrared and visible light as part of a study of galaxy cores within the Virgo Cluster, and feature a portion of the galaxy near the center.

Messier 98 is included in Hubble’s Messier catalog, which highlights some of the most fascinating objects that can be observed from Earth’s Northern Hemisphere. See the NASA-processed image and other Messier objects at: https://www.nasa.gov/content/goddard/hubble-s-messier-catalog.
