If you think you’ve met the wildest exoplanet yet, you haven’t learned about TOI-4507 b.
This strange world, which sits about 578 light-years from the solar system, breaks almost every known rule for how planets should behave. First off, it orbits a very young star that’s just 700 million years old, making it one of the youngest planetary systems ever discovered. The planet is 9x…
Citizen scientists just discovered the most powerful 'odd radio circle' twins in space we've ever seen
October 15, 2025
Citizen scientists have found several new “odd radio circles<” or ORCs, in distant, enormous galaxy clusters — and through their discoveries, scientists are learning more about how these huge ring-like structures form.
ORCs were first identified only six…
Astronomers have long called Uranus and Neptune the “ice giants” because models suggested that these outer planets’ interiors are largely made of mixtures of water, ammonia and other ices — compounds that freeze easily in deep space. But new research…
Meteor hunters rejoice! The Orionid meteor shower 2025 peaks next week with no moon in sight
October 14, 2025
Get ready stargazers! The Orionid meteor shower peaks next week overnight on Oct. 20-21, bringing with it a flurry of spectacular ‘shooting stars’ to brighten a blissfully dark moonless sky.
The Orionid meteor shower is active from Oct. 2 to Nov. 7. It occurs when Earth barrels through the trail of debris shed by Halley’s Comet as it makes its 76-year orbital tour of the solar…
Scientists open untouched Apollo 17 lunar samples from 1972 — they may hold clues about the moon's violent origins
October 14, 2025
Scientists have found that a sample of the moon brought to Earth in 1972 by Apollo 17 astronauts contains a ratio of sulfur isotopes very different to what we see on Earth. It’s a discovery that could either tell us about the giant impact that formed the moon, or about…

October 13, 2025
An amazing new video shows flashes of sunlight sparkling off a batch of SpaceX satellites, with a green aurora glowing just below.
NASA astronaut Don Pettit, an accomplished amateur photographer, captured the stunning “train” of SpaceX Starlink broadband…
The case for a newborn ocean on Saturn’s moon Mimas continues to build.
Research mapping the thickness of the world’s icy crust not only provides a window for how old an existing ocean might be but also probes where the crust might be at its thinnest — the perfect spot for future missions to detect the ocean. At the same time, examination of Mimas’ largest crater is providing…
If you’re a space buff but haven’t already seen the 1995 film “Apollo 13,” it’s worth the watch. It recreates the near-disaster mission marked by an oxygen tank explosion and emergency ocean-landing back to Earth starring Tom Hanks as Jim…

Blast off with the 'Space Gal' Emily Calandrelli for World Space Week on Arm and Hammer's Baking Soda Rocket Day
October 10, 2025
The volatile, back-and-forth relationship between baking soda and vinegar is one we all know well.
Every time the two get together, you can count on a serious — and seriously fun — reaction. But if you’re still mixing your chemical-reaction cocktails to make miniature volcanoes, today is the day to point those erupting bubbles in the other direction. Today, we’re using baking soda and…
