What you’re looking at is the most zoomed-in photo ever shot by mankind. Titled the eXtreme Deep Field (XDF), it’s a followup to the famous Hubble Ultra-Deep Field photo created in the mid-2000s. Scientists combined 10-years-worth of Hubble Space Telescope photos to create this resulting image that shows 5,500 individual galaxies, some of which are one ten-billionth the brightness of what our human eyes can see.
The amount of photography and imagery that went into this image is staggering. The Hubble “space camera” was pointed at this tiny patch of sky for a total of 50 days, with a total cumulative exposure time of over 23 days (uber-long-exposure photography, anyone?). This resulted in 2,000 individual photos showing the same little section of the sky, all of which went into creating this photograph. It’s the “deepest image of the sky ever obtained” that reveals “the faintest and most distant galaxies ever seen.”

While SpaceX works on giant reusable rockets to reach Mars, other companies are working on technologies to keep colonists alive on the red planet. Relativity Space has made the world's largest metal 3D printer, called Stargate, to print rockets, tools, and other useful objects off-Earth.
When humans take the drug MDMA, versions of which are known as molly or ecstasy, they commonly feel very happy, extraverted, and particularly interested in physical touch. A group of scientists recently wondered whether this drug might have a similar effect on other species—specifically, octopuses, which are seemingly as different from humans as an animal can be. The results of their experiment, in which seven octopuses took MDMA, were “unbelievable.”
