Brown dwarfs: too small to be stars, too big to be planets.

Scientists have unveiled a new approach to detecting gravitational waves in the milli-Hertz frequency range, providing access to astrophysical and cosmological phenomena that are not detectable with current instruments.

Phosphorus is one of six key elements necessary for life on Earth. When combined with hydrogen, phosphorus forms the molecule phosphine (PH3), an explosive, highly toxic gas.

Beyond the race for scientific, commercial and military purposes, there is another space race of a more curious sort. A race to be the first to send various objects up

A comet from another star system will swing by Mars on Friday as a fleet of spacecraft trains its sights on the interstellar visitor.

Port Canaveral has had such a busy year supporting SpaceX’s rocket recovery efforts, it brought in a new crane to assist in the launch parade on the Space Coast.

Since the early 20th century, scientists have gathered compelling evidence that the universe is expanding at an accelerating rate. This acceleration is attributed to what is known as dark energy—a

The most distant and most powerful “odd radio circle” (ORC) known so far has been discovered by astronomers. These curious rings are a relatively newly identified astronomical phenomenon, having been

Astronomers have identified an enormous “growth spurt” in a so-called rogue planet. Unlike the planets in our solar system, these objects do not orbit stars, free-floating on their own instead.

Astronomy is increasingly becoming an online affair. Recent discoveries of interstellar Comet 3I/ATLAS and R2 SWAN have highlighted this fact, when both were first discussed on message boards and verified
