Alien life may be missed by current space missions, but AI might help

It’s 2035 and NASA’s Dragonfly quadcopter has been “hopping” around the surface of Saturn’s largest moon Titan for just over a year taking images, scanning pebbles, drilling holes, and analyzing surface material for potential signs of life. You’re at NASA JPL and just moved to Blue Team (12am-8am) from Red Team (4pm-12am), so you’re hyped up on coffee, Red Bull, and will power. It’s 3:30am, you’ve been analyzing data since you clocked in, and you keep discarding what you’ve been told looks like positive signs of life but is more commonly known as false positives. In the meantime, some microbes on Titan that got scanned by Dragonfly keep posing in front of its main camera with signs saying, “We’re here!” from Universe Today https://ift.tt/AirJZqy via IFTTT

NGC 1514, the Crystal Ball Nebula, is about 1500 light years away and contains a binary pair in its center.

Is Dust the Best Thing in the Universe? Part 3: Tiny Chemistry Labs

Two hydrogen atoms can't form an H2 molecule on their own in empty space. They need a surface. The universe has only one surface available, and it's something I have just spent two articles complaining about. from Universe Today https://ift.tt/Meuc68x via IFTTT
