Which planet is the furthest from the sun? Some may think it’s Pluto, but it’s actually Neptune. Learn more about this ice ...

With temperatures reaching almost 2,000 degrees Celsius on its dayside, LTT 9779 is one of the few known planets in the "hot ...

Sometimes it’s necessary to break a few diamonds to figure out what’s happening on an alien planet’s surface. Or at least diamonds in diamond anvil cells, devices designed to squeeze materials to ...

Stars often whip their planets with stellar winds and radiation, pull them ever closer with gravity and sear them with heat. But a newfound planet exerts an unexpectedly strong—and ultimately ...

If it’s actually out there, Planet 9 would take 10,000 years to orbit the Sun. (Credit: R. Hurt/California Institute of Technology) For years, astronomers have toyed with the idea that the Sun hides ...

This artist's concept illustrates the results of a new study that measured the masses of many planets relative to the stars that host them, leading to new information about populations of planets in ...

The exoplanet K2-18b is generating headlines because researchers announced what could be evidence of life on the planet. The JWST detected a pair of atmospheric chemicals that on Earth are produced by ...

In deep space, far beyond our solar system, astronomers have spotted loads of super-Earths, mini-Neptunes, and hot Jupiters. But only once have they found an "ultra-hot Neptune" — a Neptune-size world ...

Starting in 2025 the Vera C. Rubin observatory will increase the number of known objects circling the sun by roughly tenfold, spotting new comets, exotic asteroids from other stars, and perhaps even ...

This work's sample overlaid with known transiting planets. Hexagons indicate planets in our sample also being observed by JWST through Cycle 2, while triangles are not yet scheduled or approved for ...

In a nutshell: NASA's Transiting Exoplanet Survey Satellite (TESS) spacecraft was launched in April 2018, and it quickly began detecting signs of potential exoplanets orbiting around distant stars.
