Astronomers find the first known exposed core of a gas giant

[ad_1] It’s not certain just what led to the ‘naked’ jovian world, but there are two theories. TOI-849b is so close to its star that it completes an orbit in 18 hours, raising the possibility that tidal disruptions or a planetary collision stripped it of gas. Evaporation due to starlight is a possibility, but wouldn’t […]

NASA’s TESS spacecraft discovers its smallest exoplanet to date

[ad_1] TESS spotted the planets by using transits (regular dips in the star’s brightness caused by passing planets). You might get more information soon, at least. TESS completes its first year of studies in July, and that could be enough to both collect more detail about the known planets and possibly spot more. This isn’t […]

NASA’s TESS spacecraft finds its first Earth-sized exoplanet

[ad_1] This newly identified planet is the smallest world outside our solar system that TESS has spotted. And the spacecraft’s data shows HD21749c circles its star every 7.8 days, meaning it has a tight orbit that would lead to surface temperatures of up to 800 degrees Fahrenheit. TESS has now found 10 planets smaller than […]
