The Milky Way is just one galaxy in a vast cosmic web that makes up the Universe’s large-scale structure. While ESA’s Gaia spacecraft is building a map of our stellar neighborhood, a team of astronomers with the Dark Energy Spectroscopic Instrument (DESI) Legacy Survey have released a comprehensive galactic map that includes all the data from three wide-ranging surveys completed between 2014 and 2017. Called the Siena Galaxy Atlas (SGA), it contains the distance, location, and chemical profile of 380,000 galaxies across half of the night sky.

Apollo artifacts: NASA salvages parts from Alabama's rest stop Saturn IB rocket
At the very end, it was the rocket that took itself down. The Saturn IB was in the final minutes of being laid down when it fell the last 15 feet to the ground.
Loki season 2 episode 3 review: Timely but not elegant
The third episode of Loki season 2 brings back major players, teases the creation of the Time Variance Authority and is a bit convoluted.
A New Hope? Taming the Satellite Swarm
Going by the paperwork, 1 million satellites are headed for the skies. The question is, how many of these are real? New policy may help stem the tide.
Powerful new radio telescope could unmask the ancient universe — if satellites don't ruin the view
When complete, the Square Kilometer Array Observatory (SKAO) will be the world's most powerful radio telescope — if SpaceX's Starlink satellites don't ruin its view.
The Orionid meteor shower peaks this weekend. Here's how to see it
During the third week of October, the meteor display spawned by the debris shed by Halley reaches its peak: The Orionid meteor shower.
NASA's Artemis moon astronauts may wear electric field spacesuits to fight pesky lunar dust
NASA wants to put astronauts on the moon again in the 2020s, and lunar dust is expected to pose a major issue. An electric field spacesuit project received a big grant to find a solution.
A mud lake on Mars might be hiding signs of life in chaotic terrain
Martian biosignatures might be lurking in an ancient mud lake on the Red Planet, a new study suggests. But a landing mission is needed to confirm the satellite study.

Juno Completes its Closest Flyby of Io Yet
Jupiter’s ocean moons capture most of our attention because of their potential habitability. But Io, Jupiter’s bad-boy volcanic moon, is in a class of its own. There’s nothing else like it in the Solar System, and NASA’s Juno spacecraft captured new images of the volcanic satellite during its closest approach yet.
Thinking About Time Travel Helps Solve Problems in Physics
Time travel. We’ve all thought about it at one time or another, and the subject has been explored extensively in science fiction. Once in a while, it is even the subject of scientific research, typically involving quantum mechanics and how the Universe’s four fundamental forces (electromagnetism, weak and strong nuclear forces, and gravity) fit together. In a recent experiment, researchers at the University of Cambridge showed that by manipulating quantum entanglements, they could simulate what could happen if the flow of time were reversed.
Record-breaking radio burst could help us find the universe's missing matter
An 8 billion-year-old Fast Radio Burst could help astronomers solve the mystery of the universe's missing matter.
