A team of astrophysicists has discovered a binary pair of ultra-cool dwarfs so close together that they look like a single star. They’re remarkable because they only take 20.5 hours to orbit each other, meaning their year is less than one Earth Day. They’re also much older than similar systems.

The Subaru Telescope spotted a spiral shape in the sky shortly after SpaceX sent a GPS satellite to space on Wednesday (Jan. 18).
James Webb Space Telescope's ground-breaking study of a planet-forming disk hints at future exoplanet discoveries
The James Webb Space Telescope has for the first time peered inside a planet-forming disk of dust surrounding a nearby star, a development promising to supercharge the search for exoplanets.
Mars helicopter Ingenuity aces 40th Red Planet flight
NASA's tiny Ingenuity helicopter flew for the 40th time on Mars Thursday (Jan. 19), covering about 584 feet (178 meters) of ground during a 92-second sortie.
Light Pollution Is Increasing Even Faster Than We Realized
The average brightness of the night sky is increasing by 10% every year, making the stars less visible.
Tiny, bright flashes on the sun could help scientists predict solar flares
Tiny but bright flashes in the sun's corona that precede solar flares could help astronomers predict when the next one might occur.
See the conjunction of Venus and Saturn in free webcast on Jan. 22

1st-ever recovered US rocket stage, an artifact from Gemini 5, returns to launch site 60 years later
The first U.S. rocket stage to be recovered after its launch, an artifact from Gemini 5, has landed at the Cape Canaveral Space Force Museum, not far from where it lifted off almost 60 years ago.
A new way to Peer Into the Permanently Shadowed Craters on the Moon, Searching for Deposits of Water ice
Not all flashlights are created equal. Some are stronger, consume more power, or have features such as blinking or strobes. Some aren’t even meant for humans, such as a new project that recently received funding from a NASA Institute for Advanced Concepts (NIAC) Phase I award. Designed by the Ultra Safe Nuclear Corporation (USNC), this flashlight doesn’t emit visible light, but it does emit x-rays and gamma rays, and the researchers on the project think it could be useful for finding resources on the Moon.
