Shell Galaxy Reveals Its Onion-Like Layers to Dark Energy Camera
Behold a galactic onion: the shell galaxy NGC 3923, spotted by the Cerro Tololo Inter-American Observatory’s Dark Energy Camera (DECam) at a distance of about 70 million light-years from Earth. Shell galaxies make up approximately 10% of all elliptical galaxies, one of the three main galaxy types. The other two types are spiral galaxies, like…

Antimatter Reacts to Gravity in the Same Way as Ordinary Matter, Physicists Find
In the 95 years we’ve known about antimatter, physicists have not tested how the elusive inverse of ordinary matter is affected by gravity, the force that pulls masses to Earth and seems to affect all things in the classical realm. Now, a group of physicists have. Members of the Antihydrogen Laser Physics Apparatus (ALPHA) collaboration…
