Dec 13, 2021 | Brown Dwarf, Citizen Science, Climate Change, Daily Space, Earth, Exoplanets, Milky Way, Review, Rockets, Spacecraft, SpaceX, Supermassive Black Holes

Using data provided by the Backyard Worlds: Planet 9 citizen science project, volunteers found a possible large planet or brown dwarf orbiting its star at a distance of more than 1,600 astronomical units. Plus, NASA launches the Imaging X-ray Polarimetry Explorer, and we review Ghostbusters: Afterlife.

40 Hours of Observations Finds No Dark Matter in Galaxy AGC 114905

Astronomers using the Very Large Array in New Mexico spent 40 hours observing galaxy AGC 114905, which seemed to have little to no dark matter in 2019 observations. The new evidence shows there is no dark matter in the galaxy at all. Plus, more Hubble and JWST updates, an eclipse over Antarctica, and an interview with Dr. Franck Marchis about citizen science.

Lightweight Mars-sized Planet Found in TESS Data

Dec 6, 2021 | Asteroids, Comets, Cosmology, Daily Space, Earth, Exoplanets, Our Solar System, Review

A Mars-sized planet was found just 31 light-years away, orbiting its star every eight hours and having 55 percent the mass of the Earth, leading scientists to conclude it’s mostly made of an iron-nickel core. Plus, water on Earth, a huge comet, and a review of a Canon lens.

Earth’s Orbital Changes Possibly Influenced Biologic Evolution

Dec 3, 2021 | Astrobiology, Comets, Daily Space, Earth, Galaxies, Sky Watching, Stars, Supermassive Black Holes

An analysis of over nine million samples of coccoliths whose ages span several million years has led scientists to conclude that changes in Earth’s orbit may have influenced changes in the size and shape of the microscopic algae. Plus, Europe contemplates geologic threats, and a comet is in this week’s What’s Up.

ALMA Data Helps Confirm Mechanism Behind Gas Stripping of Galaxies

Nov 22, 2021 | Astrobiology, Daily Space, Earth, Galaxies, Mars, Moon, Sky Watching, The Sun

A new research project called the Virgo Environment Traced in Carbon Monoxide Survey (VERTICO) used data collected by the Atacama Large Millimeter/submillimeter Array (ALMA) to understand just what is stripping star-forming gases out of the Virgo Cluster of galaxies. Plus, calderas, a mass extinction, and this week’s What’s Up.

Quasi-satellite of Earth has Lunar-like Material

After five years of observations, researchers have found that the quasi-satellite Kamo’oalewa, which currently orbits the Earth, is similar to a lunar sample collected during the Apollo 14 mission. Plus, Russia blows up a satellite, TESS finds a circumbinary planet, and we interview Dr. Gail Christeson of the University of Texas, Austin, about mapping the Chicxulub crater.
