Thirty years ago, a probe headed for distant space turned around and took a final photo of Earth.
Context: Known as the "Pale Blue Dot," the image has lived on, and last week NASA released a newly processed version of it that shows our world and everyone on it as a bright pixel nestled in a sunbeam.
A privately funded hunt for intelligent extraterrestrial life has turned up empty so far, but a newly released trove of data could aid in the search.
The big picture: The search for alien life has gone mainstream in recent years, with multiple scientific ventures looking for radio signals that could signify the presence of intelligent civilizations somewhere else out there.
More rain is expected to barrage Mississippi's already-flooded capital city of Jackson later on Tuesday, according to the National Weather Service.
The state of play: Heavy rain is projected to strike eastern Louisiana, central parts of Mississippi, Alabama and even into far western Georgia, the Weather Prediction Center in College Park, Maryland, predicts, per AP. As much as 2 inches is expected to fall rapidly in Mississippi, prompting flash flood warnings.
Galactic cosmic rays from outside of the solar system may change the atmosphere of Saturn's moon Titan, according to a new study.
Why it matters: Titan is one of the most intriguing objects in the solar system — with a thick atmosphere and liquid lakes of hydrocarbons — and scientists think it could harbor the ingredients necessary to support life in some form.
SpaceX has penned a deal with the space tourism outfit Space Adventures to launch private citizens to orbit aboard the company's Crew Dragon capsule.
Why it matters: SpaceX is building and testing the Crew Dragon to fly astronauts to the International Space Station, but this announcement shows they're thinking about orbital space tourism as a possible driver of revenue for them in the future.
NASA is unlikely to meet its deadline of sending astronauts to the surface of the Moon by 2024, even with a large influx of funding.
Why it matters: The Artemis mission to send people back to the Moon is the Trump administration's flagship space policy, and its aggressive, politically-motivated timeline is its hallmark.
