What’s the difference between asteroids and comets?
Asteroids and comets are generally composed of different materials and reside in different locations of the solar system, while some rare objects display characteristics of both. Source: https://earthsky.org/astronomy-essentials/whats-the-difference-between-comets-and-asteroids…
New evidence for multiple ice ages on Mars
Earth has had at least 5 major ice ages. Now it appears Mars – the next planet outward from the sun – has undergone anywhere from half a dozen to 20 ice ages in the past several hundred million years. Source: https://earthsky.org/space/new-evidence-for-multiple-ice-ages-on-mars…
Striped brown dwarf looks a lot like Jupiter
The surface features of brown dwarfs – objects midway in mass between planets and stars – can’t be seen. But researchers have found a way to reveal Jupiter-like stripes and bands in the atmosphere of the closest brown dwarf, Luhman 16B.

Winds and jet streams found on the closest brown dwarf
A University of Arizona-led research team has found bands and stripes on the brown dwarf closest to Earth, hinting at the processes churning the brown dwarf’s atmosphere from within. Source: https://phys.org/news/2021-01-jet-streams-closest-brown-dwarf.html…
New sunspot cycle could be among strongest on record
A study of oppositely charged magnetic field bands, moving in the sun’s northern and southern hemispheres, suggests the coming sunspot cycle – Cycle 25 – will be a particularly strong one. This result contradicts an earlier expert forecast, suggesting a weak Cycle 25. Source: https://earthsky.org/space/sunspot-cycle-25-among-strongest-on-record-says-ncar…
‘Super Nintendo World’ Amusement Park Previewed By Mario’s 68-Year-Old Creator
“On Friday, Nintendo and Universal Studios Japan took the veil off a years-in-the-making project: the very first Nintendo-themed theme park,” reports Ars Technica (in an article shared by long-time Slashdot reader mprindle): And who better to introduce the world to this life-sized walk through of all things Mario than the character’s creator himself, longtime Nintendo developer and designer Shigeru Miyamoto… Many…
Here’s the 5G Glossary Every American is Apparently Going To Need
T-Mobile last week introduced the market’s newest 5G moniker: “Ultra Capacity.” The label, writes blog LightReading, will stew alongside “5G Ultra Wideband,” “Extended Range 5G,” “5G+,” “5Ge,” “5GTF,” “5G Nationwide” and plain-old “5G” in the US wireless industry, ensuring that if American mobile customers aren’t confused yet, it’s only a matter of time before they’re hopelessly bewildered by operators’ thesaurus-toting marketing…
Scientists discover new way to measure turbulence of large planets and exoplanets
The swirls, eddies, and wavy bands of Jupiter and Saturn may remind us of a soothing, starry, starry night—but they reveal these two gas giants to be stormy, turbulent places. The turbulence produces energy cascades, a non-linear transfer of energy between different scales of motion. These are as fundamental to understanding planetary dynamics as the cardiovascular system is to understanding the…
