According to NASA's article on the test, this is a big step toward sending a manned mission to Mars:

NASA successfully tested the first deep space RS-25 rocket engine for 500 seconds March 10, clearing a major milestone toward the next great era of space exploration. The next time rocket engine No. 2059 fires for that length of time, it will be carrying humans on their first deep-space mission in more than 45 years.

This is all part of a plan to send humans to Mars by 2030, which NASA has laid out in this beautifully illustrated image:

The Hubble Space Telescope took this image of a star that looks like it's inside a blue bubble. NASA says the blue bubble is actually a nebula formed around 20,000 years ago. This is how it's described on the Hubble's website:

The distinctive blue bubble appearing to encircle WR 31a is a Wolf–Rayet nebula — an interstellar cloud of dust, hydrogen, helium and other gases. Created when speedy stellar winds interact with the outer layers of hydrogen ejected by Wolf–Rayet stars, these nebulae are frequently ring-shaped or spherical.


According to NASA, these type of stars don't last very long (in terms of bodies in space at least). It'll only be around for a "few hundred thousand years".
