A new mosaic image captured by the NASA/ESA Hubble Space Telescope and released on 9/24/15 shows an incredibly detailed look at a small section of the remains of a massive star that exploded about 8,000 years ago. Called the Veil Nebula, it is one of the best-known supernova remnants. The entire nebula is 110 light-years across and sits about 2,100 light-years away in the constellation Cygnus, the Swan.

On 9/10/15 scientists in South Africa announced that they had discovered a new human ancestor species. This is a composite skeleton and other fossil elements of what scientists call Homo naledi. The new hominid species shows a unique mix of human-like and more primitive characteristics. (AP)

This new image of the spiral galaxy NGC 3521 was captured by the NASA/ESA Hubble Space Telescope released on 9/21/15. It’s a member of a class of galaxies known as flocculent spirals and is located almost 40 million light-years away in the constellation of Leo. (ESA/Hubble & NASA and S.

A perigee full moon or supermoon is when a full moon makes its closest approach to Earth during its elliptical orbit. Skywatchers were treated to a rare combination of a supermoon and a total lunar eclipse on 9/27/15. Here’s a look at the supermoon behind an Orthodox church in Belarus as it nears the end of the eclipse. (AP)
