A distant 'exomoon' the size of Jupiter is changing how we think about the cosmos.

Humans discovered the first exoplanet in 1992 and have since found approximately 6,000 other planets from outside our solar ...

It circles a 'failed star' like a moon would. But scientists aren't quite sure what to call it.

Astronomers detected a strong 170-day signal suggesting a Jupiter-mass object orbits the brown dwarf CD-35 2722 B. The ...

Have astronomers observed the first exomoon, or have they spotted a weird object that could challenge the very concept of planets and moons?

This is HOPS-315, a baby star where astronomers have observed evidence for the earliest stages of planet formation. The image was taken with the Atacama Large Millimeter/submillimeter Array (ALMA). In ...

While life on Mars (and Venus) has long been an obsession for those wondering if we're alone, there are other places in our solar system that could support life in some form.

Spiral Galaxy from Kirkland et al. CREDIT Chris Kirkland and colleagues. A new study of zircon crystals from two of Earth’s oldest continents indicates that the formation of Earth’s continental crust ...

Astronomers using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) have found evidence of a Jupiter-mass object orbiting a brown dwarf in the CD-35 2722 system, a discovery ...

For obvious reasons, the Sun’s influence weakens as you get closer to the edge of the solar system. But things might be a lot more complicated than we previously thought, according to a new study.

Oh, we humans do love a cleanly defined boundary, don’t we? They make things easier, after all. If we’re trying to categorize something, knowing what labeled bin to put it in is handy. If we’re ...

In the latest research, telescope observations of 3I/ATLAS examine its chemical structure and suggest that it took shape in a peripheral region of a relatively calm planetary system ...
