A puzzling gravitational wave was detected, and astronomers have determined that it comes from a record-breaking black hole merger

It came from outer space.

The private Ax-4 astronaut mission will undock from the International Space Station on Monday morning (July 14), and you can watch the action live.

Planetary construction sites around other stars are filled with pebbles, and for the first time radio telescopes have detected these tiny chunks of rock that stick together to form planets.

With the universe constantly expanding, scientists have a hard time finding where its center is.

The winners will be announced during a ceremony in September.

"It is incredible that modern telescopic surveys have the ability to detect such small objects up to millions of kilometers away."

SpaceX launched a mystery satellite to geostationary transfer orbit from Florida's Space Coast early Sunday morning (July 13).

A team of international researchers led by Tomas Stolker in the Netherlands has imaged a young gas giant exoplanet near a 12-million-year-old star. The planet is orbiting a star whose planet formation has finished, while a same-aged companion star in this double star system still has a planet-forming disk.

In a recent study, a team of astronomers examined 27 confirmed and candidate exoplanets identified by TESS for signs of radio transmissions during star-planet occultations. The purpose was to see if radio signals from these targets of interest (TOIs) were interrupted as they passed behind their stars, thereby indicating that they were artificial in origin.

Cosmic dust does far more than float through space. It's the raw material from which stars, planets and possibly even life emerge. Yet astronomers have long puzzled over where this vast amount of dust comes from and what it's made of.

Why is there a spiral around the North Pole of Mars?
