A mysterious visitor from interstellar space is raising more questions than answers as astronomers continue tracking 3I Atlas ...

Moving is never easy. The packing and unpacking, having to start fresh and make new friends, all this can be challenging. Let ...

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

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 ...

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

Solar eclipses are a rare and brief opportunity for scientists to gather data on everything from the physics of the sun to air pressure in the upper atmosphere The evidence is mounting: this ...

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.

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 ...

Our solar system is a smashing success. A new study suggests that from its earliest period — even before the last of its nebular gas had been consumed — Earth’s solar system and its planets looked ...

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

And the earth was without form and void, and darkness was upon the face of the deep. Sometimes, if the night is dark and clear enough, you can look up and see the Milky Way in its arc across the sky.

Estimating ages of specific events is one of the most difficult problems in astrophysics. While we have a precise (and probably accurate) age for the solar system, we do not have precise ages for each ...
