A population study of 43 exoplanets orbiting M-dwarf stars to find the densities of the worlds shows the planets are less dense than expected, suggesting they are not purely rock but half-rock and maybe half-water.
Time for Weekly Space News with @WSHCrew. This week the crew discuss about technosignatures with Dr. Sophia Sheikh. Also why NASA is trying to crash on Mars on purpose, a marshmallow world, a star destroyed its planet atmosphere and ancient data finding Uranus rings.
JWST has already directly imaged its first exoplanet! What are we able to learn about these planets from the data collected? How does exoplanet geology compare with our own geology here on Earth? Plus news roundup with @WSHCrew
TOI 849b is an exoplanet located about 730 light years away from Earth. Due to its close proximity to its star the atmosphere of this exoplanet was blasted away by its host star, leaving behind a naked core. This is the first ever planetary core discovered by astronomers.
As we return from our summer hiatus, we are back with a rundown of some of the stories such as JWST images, dark matter, and Betelgeuse. Also thirty orbital launches but not including Artemis.
So we have rocky planets, gas giants, and ice giants in Solar System. What are their differences? And how about exoplanet. Are they the same?
Starting with the stunning release of JWST’s first image of galaxy cluster SMACS 0723 on July 11, the bonanza continued the morning of July 12 with newly released images of Stephan’s Quintet, the Carina Nebula, the Southern Ring Nebula, and exoplanet WASP-96b
Most if not all newly formed stars have protoplanetary disks of gas & dust circling around them. More about the HL Tauri planet which forming in the gaps.
Time for weekly update. Tonight @WSHCrew will discuss about imaging exoplanets using gravitational lens with Alexander Madurowicz. Also the possibility that Ceres moved, Insight power down, and Voyager 1 glitch.
The Earth is teeming with life, but the upper atmosphere to kilometers underground. There’s no question that our planet has life. But is our planet itself alive?
