It’s still a mystery how life got started on Earth – but maybe it didn’t start on Earth after all. A new Japanese study simulated the gigantic clouds of dust and gas that float around between the ...

Can the fastest brightening ever recorded in a comet rewrite what we know about interstellar visitors? As Comet 3I/ATLAS ...

Observations were maintained using imagery from solar imagers on the STEREO-A, SOHO, and GOES-19 missions near the Sun.

Interstellar invader Comet 3I/ATLAS is still full of surprises — an unexpected brightening has scientists baffled ...

Astronomers have captured new, detailed maps of three nearby interstellar gas clouds containing regions of ongoing high-mass star formation. The results of this survey, called the Star Formation ...

The interstellar comet 3I/ATLAS will make its closest pass to the sun on Oct. 30, and various spacecraft will be watching, ...

Astronomers have measured the distribution of mass inside a dark filament in a molecular cloud with an amazing level of detail and to great depth. The measurement is based on a new method that looks ...

Our solar system dwells in a low-density environment called the Local Hot Bubble (LHB), filled by a tenuous, million-degree hot gas emitting dominantly in soft X-rays. A team led by scientists at the ...

Berkeley - A bit of Earth-bound chemistry has led scientists at the University of California, Berkeley, to conclude that there is an unsuspected wind of low-energy cosmic ray particles blowing through ...

Chiral universe: chiral molecules discovered in the Milky Way. (Courtesy: Brett A McGuire) Scientists could be one step closer to understanding how life emerged on Earth, now that chiral molecules ...

Two astronomers from Greece have managed to model the three-dimensional structure of an interstellar gas cloud, and found that it’s on the order of 10 times more spacious than it originally appeared.

A long time ago, Mars had an atmosphere thick enough to allow running water on its surface. But today these vast gullies — and features that some scientists interpret as ocean shorelines — are ...
