Wrong! As long as you set up your lock screen and your ICE contact correctly, all an emergency worker has to do is glance at your locked screen to find your ICE Contact. Here are two different ways to set it up, depending on the model Galaxy you have. Most Samsung Galaxies have an ...
Some galaxies, such as the dwarf Galaxy calledSegue 2, do not have a Supermassive Black Hole but rather orbit a central gravitational point. The word galaxy comes from the French word Galaxie, which additionally comes from the Latin galaxias meaning "Milky Way". In ancient times, there was o...
Among early-type galaxies with almost circular isophotes, E0 and E1 galaxies are, at 99.3% significance, more luminous than face-on objects classified as S0(0) and S(0)(1). This result supports the view that rotation and "diskiness" are more important in the outer regions of faint early...
The debate on the origin and nature of UCDs, and the recently discovered ultra-faint dwarf spheroidal (dSph) galaxies which contain very few stars, has motivated us to as the question 'What is a galaxy?' Our aim here is to promote further discussion of how to define a galaxy and, in ...

While globular clusters can span hundreds of light-years, they are still dwarfed by their home galaxies, which are usually tens to hundreds of thousands of light-years across. The Milky Way, for instance, is known to contain 158 globular clusters. You may like Star cities: New 3D view of...
that resemble a pattern. Constellations are areas of the sky where we have broken the sky into parts. All the stars in the constellations are withinthe Milky Way. A galaxy is a large collection of stars containing billions or trillions of stars. Galaxies exist outside our own Milky Way ...
Blazars are the cores of galaxies that contain supermassive black holes that are millions to billions of times the size of the sun. They are some of the most luminous and energetic objects in the universe and emit light across the electromagnetic spectrum. In 1929, Cuno Hoffmeister discovered ...
Webb is known for its ability to stare unblinking into the deep sky. Since it came online, it has produced deep-field images containing thousands of distinguishable galaxies and narrow profiles of individual stars—and its repertoire is still expanding. In June 2024, JWST astronomers presented the...
Zooming out to look at entire clusters of galaxies, astronomers found that the clusters didn't contain enough mass to keep them from drifting apart. Looking more closely at individual galaxies, astronomers realized their motion was...wrong. The outside of the galaxy rotated around its core at...
