A new study lets some of the air out of a long-held theory that growing, rocky planets will lose their atmosphere if they smash into a large object in space. In fact, these kinds of collisions often help proto-planets hold…

Astronomers have confirmed for the first time with direct evidence that a lone, starless world is actually drifting through the Milky Way. Though scientists have documented a dozen of these so-called "rogue planets" in the past decade, this one isn't…
A brilliant red star beaming through our night sky is Betelgeuse, an aging supergiant on the shoulder of the Orion constellation. For years astronomers have watched this star — pronounced "Beetlejuice" just like the Michael Keaton character — with some convinced it's…
New radio observations with NSF’s Karl G. Jansky Very Large Array (VLA) and the Atacama Large Millimeter/submillimeter Array (ALMA) show the red supergiant star’s outer atmosphere has rebounded and hint that its recently identified companion star is reshaping it.
Webb observations suggest TOI-561 b reflects most of the starlight reaching it. Clouds formed from vaporized minerals could explain its surprising brightness. TOI-561 b should be a naked ball of lava. The planet orbits so close to its star that…
James Webb Space Telescope observations suggest that exotic mineral clouds may be shielding a distant lava planet from its star. A rocky planet exposed to extreme heat from its star appears to reflect nearly three-quarters of the starlight that reaches…
Astronomers have discovered an unusual planet with an extremely hot host star and a highly eccentric orbit that challenges expectations for its class. A giant planet racing around an unusually hot star has caught astronomers’ attention because of its highly…
TOI-561b, a rocky exoplanet so close to its parent star that its year lasts just over 10 hours, may be wrapped in a thick, reflective atmosphere, according to a new analysis of data gathered by the NASA/ESA/CSA James Webb…
Astronomers may have just discovered our solar system’s sixth dwarf planet Located farther away from Earth than Pluto, the object was hidden in the light of the Milky Way’s stars By Adam Kovac edited by Claire Cameron NSF–DOE Vera…
Planets around other stars: new exoplanet discoveries, habitable worlds such as K2-18b, and the search for biosignatures in their atmospheres.
