Hey everyone!...

The Subaru Telescope has made an exciting discovery: a small body beyond Pluto, with implications for the formation, evolution, and current structure of the outer solar system....

A team of astronomers led by the Center for Astrophysics | Harvard & Smithsonian has discovered a rare object far beyond Neptune, from a class known as trans-Neptunian objects, that is moving in rhythm with the giant planet. This object, called 2020 VN40, is the first confirmed body that orbits the sun once for every ten orbits...

Our circumstances here on the wondrous, life-supporting Earth can give us a false understanding of what the Universe is really like. But our blue-skied, temperate planet is the extreme exception when it comes to other worlds. There’s nothing remotely like Earth in our Solar System, and exoplanet studies reinforce that idea....

Astronomers have detected a giant exoplanet—between three and ten times the size of Jupiter—hiding in the swirling disk of gas and dust surrounding a young star....

With the recent first light milestone for the Vera Rubin Observatory, it’s only a matter of time before one of astronomy’s most long-awaited surveys begins. The Legacy Survey of Space and Time (LSST) is set to start on November 5, and will scan the sky of billions of stars for at least ten years....

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....

There’s a new object in the solar system headed toward the sun, and it may have come from interstellar space. We only know of two other interstellar objects that have entered into our solar system before, ‘Oumuamua and Comet 2I/Borisov. The nature of ‘Oumuamua is still a matter of debate, and the second was a comet from...

Some planets take the expression “you’re your own worst enemy” to the extreme. At least, that’s what astronomers found when they recently discovered a doomed planet clinging to its parent star so tightly that it’s triggering explosive outbursts and destroying itself....

A rare astronomical sight is unfolding in the southern sky. Two exploding stars are shining so brightly that both can be viewed with the naked eye....

The scientists who precisely measure the position of Earth are in a bit of trouble. Their measurements are essential for the satellites we use for navigation, communication and Earth observation every day....
