Cosmic Billiards Leads to Inner Planetary Growth

Sep 29, 2021 | Black Holes (Stellar), Climate Change, Daily Space, Earth, Mars, Mercury, Moon, Our Solar System, Stars, Venus

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.

Clouds Detected on Exoplanet WASP-127b

Sep 27, 2021 | Daily Space, Earth, Exoplanets, Galaxies, Mars, Perseverance, Review

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.

Penguin Poo Reveals Past Populations

Sep 22, 2021 | Asteroids, Climate Change, Daily Space, Earth, Mars

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.

Dark Matter Delays Supernova Signal

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”.

Supervolcanoes Remain Active Post-Eruption Longer Than Thought

Sep 17, 2021 | Daily Space, Earth, Jupiter, Mars, Mercury, Sky Watching, Venus

Research into the Toba caldera and its super-eruption 75,000 years ago shows that magma continued to flow out of the volcano for thousands of years after the main eruption event. Plus, magma and volcanoes throughout our solar system as well as our weekly What’s Up segment.
