After sunset this evening, look 15 degrees up from the southwest horizon. There you’ll see a crescent moon, 30 percent illuminated. Hovering almost directly below it will be Mars, which looks like a moderately bright yellow-orange star.

Researchers using data gathered by NASA's Hubble Space Telescope have determined that the supernova SN 1993J — which was first observed in 1993, as its name suggests — occurred because one star nabbed hydrogen from another.
19 September 2014, 10:00 AM ET
The Chile-based Atacama Large Millimeter/submillimeter Array (ALMA) and other telescopes employed a sort of cosmic magnifying glass to look at details of a galaxy called H1429-0028, revealing that the object is actually two merging galaxies.
19 September 2014, 08:30 AM ET
The galaxy lies 11 billion light-years from Earth, so viewing it gives astronomers a glimpse into processes that occurred less than 3 billion years after the Big Bang that created the universe.
18 September 2014, 01:39 PM ET
The gas giant WASP-18b, 10X larger that Jupiter, orbits its relatively young parent star in just 23 hours. With the planet that close, the star’s magnetic field may be damped so much it is emitting x-rays at old age star rates.
18 September 2014, 12:23 AM ET
This stunning space wallpaper from the VLT Survey Telescope at ESO’s Paranal Observatory in northern Chile shows the globular cluster Messier 54. This cluster looks very similar to many others, but it has a secret.
