The Hubble Space Telescope is one of the great achievements in modern astronomy, still producing stunning and scientifically valuable images after more than 30 years of operation. Each week, scientists working with Hubble share an image captured by the telescope, and this week’s image shows a snippet of a famous nebula along with two bright stars.
The star V 372 Orionis is of a particular type called a variable star, meaning that its brightness changes over time. Certain variable stars, called Cepheid variables, are especially important to astronomy because they brighten in a particular way, which means they can be used to accurately estimate distances to extremely far-off galaxies. V 372 Orionis is a different type of variable, however, called an Orion variable.
