The inner solar system was a wild and wooly place as the planets were forming, and new research shows that the collisions that formed Earth and Venus were likely of the hit-and-run variety. Plus, polar ice loss warps the planet, and a black hole eats a star.
Using data from the Hubble Telescope and the ESO’s Very Large Telescope in Chile, a team of scientists have successfully detected clouds on an exoplanet and even measured their altitude. Plus, fossil evidence of humans’ arrival in North America and a review of the first episode of “Foundation” on Apple TV+.
While searching for objects deep in the universe’s history, at about three billion years of age, researchers found six massive but “dead” galaxies in Hubble and ALMA data, a strange finding for a time period known for prolific star birth. Plus, planetary science from the EPSC2021 conference and this week’s What’s Up.
This week’s Rocket Roundup includes Inspiration4, the first all-private citizen orbital spaceflight. Plus, a Chinese crew returns to Earth, and China sends up a resupply spacecraft to prepare for their next crewed expedition. And this week in rocket history looks back at the Surveyor 2 mission.
A study of the feces of Adélie penguins from Inexpressible Island on the Ross Sea of the Antarctic sheds new light on how the avian population may survive during climate change. Plus, the possibility for life on Mars and understanding destructive meteors.
A supernova first observed in 2016 will be replayed in a few years because of the light’s journey through a galaxy cluster and how dark matter gravitationally warps space-time. Plus, inactive centaurs, a Scottish ice wall, and a review of “Countdown: Inspiration4 Mission to Space”.
