Hundreds of thousands of volunteers have helped to overturn almost a century of galaxy classification, in a new study using data from the longstanding Galaxy Zoo project. The new investigation, published in the journal Monthly Notices of the Royal Astronomical Society, uses classifications of over 6000 galaxies to reveal that “well known” correlations between different features are not found in this…

Hubble survey captures iconic spiral galaxy NGC 2903
The iconic appearance of a spiral galaxy is exemplified here in the form of the stunning NGC 2903, imaged by the NASA/ESA Hubble Space Telescope. It shows off whirling, pinwheeling arms with scatterings of sparkling stars, glowing bursts of gas, and dark, weaving lanes of cosmic dust.

Image: Mature galaxy mesmerizes in new Hubble view
This striking image was taken by the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 (WFC3), a powerful instrument installed on the telescope in 2009. WFC3 is responsible for many of Hubble’s most breathtaking and iconic photographs. Source: https://phys.org/news/2019-06-image-mature-galaxy-mesmerizes-hubble.html…

Image: Hubble sees a galaxy bucking the trend
This luminous orb is the galaxy NGC 4621, better known as Messier 59. As this latter moniker indicates, the galaxy is listed in the famous catalog of deep-sky objects compiled by French comet-hunter Charles Messier in the 18th century. However, German astronomer Johann Gottfried Koehler is credited with discovering the galaxy just days before Messier added it to his collection in…

Hubble spies curious galaxy moving a little closer
This Hubble image stars Messier 90, a beautiful spiral galaxy located roughly 60 million light-years from the Milky Way in the constellation of Virgo (the Virgin). The galaxy is part of the Virgo Cluster, a gathering of galaxies that is over 1,200 strong. Source: https://phys.org/news/2019-05-hubble-spies-curious-galaxy-closer.html…

Polaris is the North Star
Many people think Polaris is the sky’s brightest star. In fact, Polaris ranks only 50th in brightness. Still, Polaris is famous because the entire northern sky wheels around it. Source: https://earthsky.org/brightest-stars/polaris-the-present-day-north-star…
