Abrand-new Hubble imagedelivers an incredible view of a quasar, enabling the space telescope to “peer closer than ever into the throat of an energetic monster black hole.” The new views, described as “weird,” show what could be a group of galaxies falling into a black hole. Quasars a...
The results of their approach were better than 90% based on 10-fold cross validation to classify a galaxy as either an elliptical or a spiral. These galaxy classification methods have provided powerful results. However, there is another trend to deal with galaxy images, i.e. to determine the...
comparable in size to our galaxy, the Milky Way. Both Messier 61 and our home galaxy belong to a group of galaxies known as the Virgo Supercluster in the constellation of Virgo (The Virgin)—a group ofgalaxy clusterscontaining up to 2,000 spiral andelliptical galaxiesin total. ...
This packed image taken with the NASA/ESA Hubble Space Telescope showcases the galaxy cluster ACO S 295, as well as a jostling crowd of background galaxies and foreground stars. Galaxies of all shapes and sizes populate this image, ranging from stately spirals to fuzzy ellipticals. This galact...
We use a Spitzer IRAC 3.6- image to perform a detailed structural analysis of this galaxy. If one fits to this image only bulge and disc components, the bulge occupies a locus in the masssize relation close to that of elliptical galaxies. When an outer stellar spheroid is added to improve...
A new image from the Hubble Space Telescope shows a small dwarf galaxy called IC 3430 that's located 45 million light-years away. This galaxy is classified as both a dwarf galaxy, because of its small size, and an elliptical galaxy, because of its form. ...
Together with irregular galaxies, spiral galaxies make up approximately 60 percent of the galaxies in the local universe. However, despite their prevalence, each spiral galaxy is unique—like snowflakes, no two are alike. This is demonstrated by the stri
Messier 31 is classified as aspiral galaxy, but it looks elliptical because it is tilted at an angle from our vantage point on Earth. This galaxy isextremely brightcompared to most others we see in the night sky. The galaxy lies 2.5 million light-years away from us, and it is similar to...
In the northern constellation of Coma Berenices (Berenice’s Hair) lies the impressive Coma Cluster — a structure of over a thousand galaxies bound together by gravity. Many of these galaxies are elliptical types, as is the brighter of the two galaxies dominating this image: NGC 4860 (cent...
Jupiter is full of surprises, and this image shows how the weather on the planet is changing — especially in the Great Red Spot, the large circular structure shown in orange which is a superstorm stretching nearly 10,000 miles across. That means this spot is so large it could swallow the...
