A strange, layered structure in deep space has captured astronomers’ attention, looking uncannily like a cosmic sandwich ...

How can fission-powered propulsion help advance deep space exploration, specifically to the outer planets like Jupiter, Saturn, Uranus, and Neptune? This is what a recent study presented at the 56th ...

TL;DR: NASA's James Webb Space Telescope has observed grains the size of a single bacterium, which are expected to eventually form planets. The world's most powerful space telescope has captured ...

Astronomers have discovered a rare lemon-shaped planet called PSR J2322-2650b orbiting a city-size star. Found using NASA’s James Webb Space Telescope, the Jupiter-size world is stretched by extreme ...

Some 2.5 million years ago, viruses in Lake Tanganyika experienced an unexplained explosion in diversity. A new study analyzing iron-60 found in the lakebed suggests that the explosion of a ‘nearby’ ...

In April, scientists captured global attention by announcing they’d found a molecule in a faraway planet’s atmosphere that could signal life there. But a new analysis by University of Chicago ...

Much of the universe's regular "baryonic" matter is spread through intergalactic space and in diffuse halos around galaxies, researchers proposed after studying the behavior of fast radio bursts ...

Billions of years from now, the Sun will swell into a red giant, swallowing Mercury, Venus, and Earth. But that’s not the only way our planet could meet its demise. A new simulation points to the ...

A 3.5-gallon volume of deep space, specifically within the Milky Way's Orion-Cygnus Arm, would contain approximately 4 million neutrinos and about 13,000 gas atoms, predominantly hydrogen and helium.

"Returning the scientifically selected samples that await us on Mars, as part of a balanced portfolio, will help to ensure the US does not cede leadership in deep space to other nations, such as China ...
