Cosmic Manatee with a Particle Accelerator on its Head
Scientists observing the Manatee Nebula find that the supernova remnant contains a stellar-mass black hole that is emitting powerful, high-energy jets, creating the strange, double-lobed shape. Plus, rocket launches, mission updates from Mars and the Moon, and a spinning galaxy from the early universe.

Climate Change: Oxygen, Dinosaurs, Ice, and Earth
From the Great Oxidation Event to how Earth is dimming, we look at a selection of stories about how climate changes have affected the Earth in the distant past, the recent past, and the current time. Plus, we review an app called MeteorActive.
Large Comet Discovered; Won’t Get Past Jupiter
Contrary to recent clickbait headlines, a recently discovered comet that likely originated in the Oort Cloud will not be coming near Earth. The closest point of the icy body’s orbit is between Saturn and Jupiter. Plus, how floods shaped Mars, how microbes helped clover grow, and this week’s What’s Up.
Rocket Roundup for September 29th, 2021
For Rocket Roundup, we have the latest in a long series of US weather satellites, a Chinese remote sensing satellite on a small rocket’s return to flight, and another secret Chinese satellite launched into an unusual orbit. Plus, this week in rocket history we look back at the first competition flight of SpaceShipOne.
Cosmic Billiards Leads to Inner Planetary Growth
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
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+.
Six Early, Massive, “Dead” Galaxies Found in Hubble Data
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.
